AnalysisofofInformation the role of transaction in supplier selection Journal Technologycosts (2003) 18, 53–67 53 What will it take for China to become a competitive force in offshore outsourcing? An analysis of the role of transaction costs in supplier selection ZHONGHUA QU and MICHAEL BROCKLEHURST The Business School, Imperial College, London, South Kensington Campus, London SW7 2AZ, UK Using transaction costs theory this paper argues that transaction costs are almost as significant as production costs when it comes to offshore outsourcing and, moreover, that it is in the field of transaction costs where China has been unable to compete with India in the supply of information technology outsourcing. The paper outlines a framework for analysing transaction costs and uses the framework for pinpointing where China is unable to compete. The paper concludes with a review of the policy implications for the Chinese Government. Introduction Information technology outsourcing is said to have originated with the Kodak–IBM outsourcing agreement of 1989 (Loh and Venkatraman, 1992). Yet the form and range of IT outsourcing have undergone two key transformations since that date. First, it has expanded beyond just the outsourcing of IT to encompass entire business processes, which are underpinned or enabled by IT. Such business process outsourcing, such as customer interaction centres, have grown rapidly, but the claim is that the growth will accelerate. Thus, the Gartner group estimate that the market grew from $100 billion in 1999 to $150 billion in 2001. However, this is predicted to reach $300 billion by 2004 (Bravard, 2002). The second transformation is the spread from onshore to offshore outsourcing. This trend to offshore outsourcing is largely serendipitous. The enormous amount of reprogramming required by 2000 meant that domestic suppliers could not meet the demand and firms in the USA and Europe had to take a chance on overseas suppliers in spite of concerns about quality. However, most of these concerns proved groundless and offshore outsourcing began to mushroom. The split between onshore and offshore outsourcing is difficult to determine with any degree of precision. However, companies in the USA will spend more than $17.6 billion on offshore outsourcing in 2005, tripling from $5.5 billion in 2000 (Prencipe, 2001). Another approach is to look at it from the supply side. India is known to be the principal offshore vendor of IT services, claiming at least 80% of the world’s business. The India software and IT-enabled services export industry has achieved an annual growth rate as high as 62.3% for the last 5 years. Total exports of $7.78 billion were achieved in 2001 and are expected to reach $23 billion in 2005 and $50 billion in 2008 (www.nasscom.org). The immediate question is why it should be India that has the lion’s share of this market and not China. After all, in the last decade China has been hugely successful in attracting offshore manufacturing. However, the story is different in the IT offshore outsourcing market. In 2001, Chinese export revenue in software and IT-enabled services was only $720 million, less than one-tenth of India’s (www.nasscom.org). One of the most important factors in the growth of offshore outsourcing in manufacturing was the global market channel built up by companies and individuals from Hong Kong and Taiwan, particularly in the early stages. However, Hong Kong and Taiwan have no experience in the software outsourcing market and so cannot help in this respect. This is of concern to the Chinese Government. In common with other developing countries such as Malaysia (Tidd and Brocklehurst, 1999), the Chinese Government wants to try to move away from labour-intensive and low value-added manufacturing to more highly value-added services which the offshore IT market provides. This will become essential as Chinese living standards rise and it ceases to be competitive as a source of cheap manufacturing labour. Moreover, there is a window of opportunity based on three factors. First, it is unlikely that India will be able to produce the qualified manpower required to meet burgeoning world demand sufficiently. India currently has approximately 445 000 IT workers and this is expected to grow to 625 000 by 2005. However, the demand for offshore IT workers will reach more than Journal of Information Technology ISSN 0268-3962 print/ISSN 1466-4437 online © 2003 The Association for Information Technology Trust http://www.tandf.co.uk/journals DOI: 10.1080/0268396031000077459 54 1 million by 2005, as compared with 360 000 in 2001 (Greenemeier, 2001). Second, putting all of your offshore outsourcing in one country is too risky: buyers prefer to outsource to different countries in order to spread the risk. Third, military tension between India and Pakistan is creating uncertainty. This paper is organized as follows. In the next section the nature of the Chinese Software Industry and current Chinese Government policy for trying to compete with India will be briefly outlined. The third section critiques transaction costs theory and examines why it is of value in this context. In the fourth section transaction costs are used for comparing production costs with transaction costs. The fifth section develops a simple framework for enabling transaction costs for two national industries to be compared. In the sixth section the paper turns to comparing China and India in terms of transaction costs and the final section sets out a policy agenda for the Chinese Government. Chinese Government policy and the Chinese software industry According to the China Software Industry Association (2002), China has 5700 software companies of which 70% employ less than 50 employees each and a further 20% employ only 100–500 employees. Only 50 companies have more than 1000 employees. As for revenue, most of these earn less than $10 million and only 18 companies make above $50 million. International software companies dominate most of the China software product markets. Domestic suppliers only manage to dominate accounting applications, anti-virus tools, Chinese platform and solutions for some industries. In total, 250 000 professionals work in the software industry. In 2001, the entire software and services market was $9.6 billion, composed of $4 billion software products, $4.9 billion services and only $700 million exports. Chinese Government policy is detailed in its document Policies on Encouraging the Development of Software and Integrated Circuit Industries, which was issued by the State Council in June 2000 (www.mii.gov.cn). Some of the policy initiatives that have been so successful in the realm of manufacturing have been applied to the software industry. Preferential taxation and special zoning arrangements, including high-tech parks to attract domestic and foreign investors, have sprung up. Many regional and local government organizations have echoed these national initiatives by providing further subsidies such as corporation and individual income tax deductions, low interest loans, 3 years rent-free offices in software science parks and investment in the education of IT labour. However the Chinese Government believes there are three problems that currently hamper the software Qu and Brocklehurst industry and it has devised three key policy initiatives for addressing each in turn. First is the shortage of qualified labour. Here the response has been to go for expansion in education and training. The Chinese higher education sector has achieved considerable growth in the last 3 years but the growth will accelerate dramatically. Graduates will increase from 1.08 million in 2002 to 3.767 million in 2004 (www.moe.edu.cn). There is also an expansion in IT training: recently, Microsoft, IBM and some Indian IT training firms have invested heavily in IT. Thus, the supply of new IT professionals should cease to be an issue after 2004. Second is the perception that China is way behind India in terms of quality when it comes to IT supply. China may be able to compete with India in terms of cost, but it lags well behind India (and other high-cost suppliers such as Ireland, Singapore and Israel) when it comes to quality (Amoribieta et al., 2001). A major indicator of quality is whether or not a supplier has quality certification. The government believes that this problem will be partly addressed by its education and training measures, but its major initiative is to encourage firms to seek quality certification by means of an incentive refunding plan. The Capability Maturity Model (CMM), a worldwide certification developed by the Software Engineering Institute of Carnegie Mellon University, is becoming the industry standard in the offshore outsourcing market. Generally, buyers only deal with suppliers that have a level 3 or higher CMM certification. Compared with India, China lags far behind on CMM certification. At June 2002, only six Chinese software companies had CMM level 3 or above certification and these awards were all recent. The only level 5 company is the Motorola China R&D centre, which focuses exclusively on internal business anyway. Huawei Technology, a telecom equipment manufacturer and a level 4 company, actually outsources to Indian suppliers. Thus, there are only four Chinese companies that have much chance of getting onto the shortlist of a prospective client. Compare this to India where 45 companies have level 5, a further 28 level 4, and 16 more have level 3 certification (www.sei.cmu.edu, www. nasscom.org and www.sina.com). Third is the fragmented nature of the Chinese software industry noted above. According to Orbys Consulting, the average contract size of an offshore outsourcing is $7.2 million and the average contract duration is 3.3 years, which works out at $2.18 million per year (ComputerWire, 2001a). However, the average revenue of a Chinese software company is less than $600 000 (China Software Industry Association, 2002). Moreover, seeking CMM certification is an expensive undertaking for smaller vendors. It would appear that the fragmented nature of the Chinese software industry is a severe Analysis of the role of transaction costs in supplier selection impediment. The government response is to encourage the formation of ‘software export clusters’ trying to overcome the firm-size barriers in the offshore outsourcing market. In order to assess the merits of this strategy requires determining why outsourcing occurs in the first place. It is argued in the next section that transaction costs theory provides a useful framework for answering this question, particularly in relation to offshore outsourcing. Transaction costs theory: a critique Hui and Beath (2002) provided a useful summary showing the various theoretical perspectives that have been applied to outsourcing. They noted that, although the early theory-based literature drew heavily on transaction costs theory, recently there has been much more interest in applying a resource-based view or social exchange theory to understanding outsourcing decisions and outcomes. However, as Hui and Beath (2002) observe, much of the literature has focused on the buyers side and been applied at the level of the individual firm. The focus in this paper is much more at the national level and concerned with the implications for the seller. To this end the authors wish to reclaim transaction costs theory, as they believe it still has much to offer although they recognize its limitations. Transaction cost theory, which was pioneered by Coase (1937) and developed principally by Williamson (1975, 1985a), is based on the assumption that human beings are utility maximizers and firms are profit maximizers. In pursuit of these objectives, agents are boundedly rational and sometimes display opportunistic behaviour. The paradigmatic question of transaction costs theory is the ‘make-or-buy’ decision: should a firm carry out an economic activity in-house or should it be outsourced? Williamson (1985b) referred to these as modes of governance–organizational hierarchy and the market respectively. In making this decision firms balance the savings made in production costs (because a supplier can provide the goods/services more cheaply) against the transaction costs that result from outsourcing. These costs include operational costs (e.g. search costs) and contractual costs (e.g. the costs of writing, monitoring and enforcing a contract) (Gurbaxani and Whang, 1991). If the savings in production costs exceed the transaction costs then it is worth outsourcing and vice versa. A basic knowledge of transaction costs theory is assumed, as excellent guides are readily available (e.g. Douma and Schreuder, 2002). One of the key criticisms of transaction costs theory is that it is too stark: make or buy – organizational hierarchy or the market. However, there are intermediate governance structures. Firms often establish long-term relationships, 55 which are neither one-off nor pure market in form (spot contracting), nor do they involve purely internal hierarchies: there are forms of long-term relationship which outlive the one-off buy/sell. (As noted above, the average length of an offshore IT outsourcing contract is 3.3 years (ComputerWire, 2001a).) Ouchi’s (1980) work on clans and, more recently, the literature on network organizations (Thompson et al., 1991) and communities of practice (Wenger, 1998) have demonstrated how nuanced the relationship between buyers and sellers can be. Indeed Williamson (1989) himself rehearsed some of these forms with his category of ‘relational contracting’. A second line of attack is that almost all of the literature on transaction costs theory relates to manufacturing rather than services and that services may be quite different. Wang’s (2002) work is one of the few exceptions (see also Murray and Kotabe, 1999). He applied transaction costs theory specifically to customized software as applied to IT in the following way. (1) Asset specificity: this refers to ‘the degree to which an asset can be redeployed to alternative uses and by alternative users without sacrifice of productive value’ (Williamson, 1989, p. 142). (i) Functional/Information requirements. (ii) Operating procedures. (iii) Business domain knowledge required. (iv) Training for the developers. (v) Technical skills required. (2) Uncertainty. (i) Requirements specification. (ii) Delivery dates. (iii) Costs. (3) Opportunism. (i) The contractor ‘reinterprets’ the contract. (ii) The contractor fails to deliver on things that are expected by the buyer, but are not in the contract. Using this classification his results show that ‘contractor reputation and uncertainty have the predicted effects on the contractor’s post-contractual opportunism perceived by the client and outsourcing success, but asset specificity has a negative effect on post-contractual opportunism and a positive effect on the outsourcing success, which are opposite to the typical predictions of TCT’ (Wang, 2002, p. 153). However, from this study’s perspective the most valuable feature of transaction costs theory is that it focuses on the comparison between production costs and transaction costs. To recap, if a supplier can produce something for a buyer for less than the buyer can produce it and the difference is greater than all the costs in managing the transaction, then it is worth the buyer outsourcing. However, what is the relative importance of production and transaction costs in outsourcing IT? Qu and Brocklehurst 56 Ang and Straub (1998) made the first attempt to compare the relative effects of production and transaction costs on onshore outsourcing decisions in the IT context. Their study shows that information systems outsourcing in USA banks was strongly influenced by the production cost advantages offered by vendors. Transaction costs played an important role in the outsourcing decision, although they were much smaller than the production costs. According to their model, the coefficient for production cost advantage is approximately six times larger than that of transaction costs. This suggests that the effect of production costs on the decision whether to outsource or not is far greater than that of transaction costs, even though both are significant. However, their questionnaire simply asked their respondents to state whether production costs were more (or less) significant than transaction costs. It gives only a qualitative feel for which is the more important. Nevertheless, the strong inference is that, when it comes to onshore outsourcing, transaction costs are relatively trivial in comparison to production costs. However, this paper wishes to argue that, when it comes to offshore outsourcing, the relative significances of production and transaction costs are markedly different. Indeed, transaction costs are much more significant and production costs less so. Intuitively one would expect transaction costs to be higher when a buyer and seller are based in different countries. However, one would also expect production costs to be much greater as that is the principal reason for buyers going offshore in the first place, namely to take advantage of wide differences in labour costs. In order to make the point, in the next section a simple analytic model for transaction costs theory is set up, which allows direct comparison between production and transaction costs. Published data are then used for providing some approximate weights to the two elements. Using transaction cost theory for comparing production and transaction costs Recall that firms outsource a job only if the advantage gained by lower production costs is bigger than the transaction costs. This rule can be expressed as follows: ∆ = ( Pin − Pout ) − Tout × Pin , Pout , × Tout ≥ 0 (1) where Pin is the in-house production costs, Pout is the outsourcing production costs, Tout is the transaction costs of outsourcing and ∆ is the net gain of outsourcing. Firms will outsource only if ∆ ≥ 0. The transaction costs of outsourcing can be analysed quantitatively, at the limit. First, transaction costs cannot be lower than zero, but could be zero if firms made no effort regarding the transaction. Second, since the outsourcing production costs cannot be lower than zero, the maximum transaction costs of outsourcing cannot be higher than the in-house production costs, otherwise firms would not outsource anything. Thus, Pin ≥ Tout ≥ 0 (2) Pin − Pout ≥ Tout ≥ 0 (3) Equation (2) has defined the widest range of transaction costs. It is arguable that, in a specific case, the transaction costs might be above the production cost gain or even higher than the in-house production costs and the outsourcer would therefore lose money. Although this is possible in theory, it is unsustainable because firms would cancel this kind of outsourcing contract as soon as possible once they realized the loss involved. Both in-house and outsourcing production costs should be quantitatively measurable ex ante or ex post (that is before or after the deal is made) with the data from historical transactions, internal budgeting, outsourcing contracts and the actual accounting records. Empirically, in each specific outsourcing case the transaction costs could be quantitatively measured ex post. There are two ways of doing this. One is activity-based costing, which totals up the costs of all related activities. The other is to find the difference in the firm’s profit before and after outsourcing, assuming nothing has changed except outsourcing and then compare this profit gap with the production cost gain. The difference is the transaction costs. This method can be expressed as follows: Tout = ( Pin − Pout ) − ∆ profit (4) where ∆profit is the profit after outsourcing minus the profit before outsourcing. It is more difficult to measure transaction costs ex ante for outsourcing clients. However, it is at least possible to estimatè their maximum transaction costs, which is the production cost gain from outsourcing: Pin – Pout. It is not difficult to get the in-house production costs ex ante. As the IT outsourcing market is relatively mature and many suppliers compete in it, it is easy to estimate the mean outsourcing production costs as well. Now, by knowing the maximum gain (∆ = Pin – Pout when Tout = 0) and the maximum payment (Tout = Pin – Pout, when ∆ = 0), complex outsourcing decisions could be simplified by finding an acceptable balance between the benefits and risks. The transaction costs will then be dependent on how much risk the firm is willing to take. The lower the risk the firm takes, the higher the transaction costs the firm has to pay. (See Jurison’s (1995) model based on transaction costs theory and the capital asset pricing model.) The next step is to try and estimate the relative importance of production costs and transaction costs and here the paper turns to published sources of data. Analysis of the role of transaction costs in supplier selection Amoribieta et al. (2001) attempted a comparison of onshore and offshore software development costs, which is reproduced in Figure 1. The production costs of onshore in-house development in the USA are expressed as 100 in Figure 1. The production costs of offshore outsourcing are expressed as 25. Therefore the savings on production costs should be 75. However, other research shows that the actual average cost saving for US customers is approximately 25 (Greenemeier, 2001). This leaves a gap of 50. The temptation is to say that these must all be transaction costs. However, the figure of 50 will now be inspected more closely. Almost all outsourcing contracts involve a proportion of the suppliers working at the client’s base (e.g. in the USA). If just Indian workers are considered (recall that Indian companies have 80% of the market), then Table 1 shows the breakdown of Indian IT and service export revenues on-site (in the USA) and offshore (in India). The relative proportion of on-site to offshore fluctuates, but the most recent figure puts it at almost 50:50. Let it be assumed for the moment that all Indian on-site workers are paid at the same rate as their US colleagues. Now returning to the breakdown in costs in Figure 1, then for those Indians who work on-site in the USA, labour costs will be 50 and additional statutory costs (taxes and insurance) will be 15, which gives a figure of 65 for those Indians working in the USA. 57 However, Figure 1 shows that, for those Indians working in India, the labour costs are 7 and the statutory costs are 3, which gives a total of 10 for those Indians working in India. Using the 50:50 split derived from Table 1 this means that the labour costs are on average 65 + 10 divided by 2, which gives a figure of 37.5 for the offshore labour costs as a whole. From Figure 1 the offshore mark-up (8) and the travel and other expenses (7) need to be added in, which gives a total of 52.5. Therefore the production costs of offshore outsourcing are not 25 but 52.5 and the gap is reduced from 50 to 22.5. This would put transaction costs at 22.5. However, it is known that the assumption that Indian on-site workers will be paid the same as their US counterparts is unrealistic. They are likely to be paid less (although not as little as their fellow offshore workers working back in India). How much less will vary according to the types of work permit held (H-1B or B1), human resource and pay policies of different US firms, etc. Table 2 shows some of the differences, but does not enable a mean figure for the differentials in wages to be specified. All that can be said is that the transaction costs are likely to lie somewhere between 22.5 and 50. If a figure midway between these two is taken it will give a figure of 36.25 for the transaction costs. It is known from Table 1 that, if there were no transaction costs, the difference in production costs Figure 1 Normalized cost structure of software development.

Source: www.nasscom.org. would be 75 between in-house development and pure offshore development. However, if the transaction costs are 36.25 then the real difference in production costs, which takes account of the realities of offshore outsourcing (partly at the client’s base), is 75 less 36.25, which gives a figure of 38.75. This means the increase in the transaction costs for offshore outsourcing is 36.25 while the saving in production costs is 61.25. This can be approached another way. Let the cost of in-house production be stated as 100. According to Amoribieta et al. (2001), labour accounts for more than 75% of the costs of developing software. Thus, labour costs in-house can be expressed as 75 and other costs as 25. However, it is also known that the offshore labour cost is approximately one-fifth of that of the onshore labour cost (Heeks, 1996). This means that the offshore labour costs can be expressed as 20% of 75, which gives a figure of 15. Add in non-labour costs (which it will be assumed are the same as for those in-house, i.e. 25) and then the total cost of offshore production is 40, a saving in production costs of 60. This has been confirmed from other sources: ‘there are currently hundreds of companies in India offering these services to companies in the US and Europe for as little as 40% of the cost of going to a local system integrator or software VAR’ (ComputerWire, 2001b, p. 10). However, according to Forrest Research the mean gain from offshore outsourcing is only 25% (Greenemeier, 2001), not 60 as might be expected Therefore, a 35% gap that represents the increase in transaction costs for going offshore is found. This is close to the figure of 36.25 derived from the first estimate. This paper does not pretend that these figures are precise and they depend on making a number of assumptions, but it can be argued that these assumptions are not unrealistic. To conclude, unlike onshore outsourcing where the transaction costs appear trivial in comparison to the production costs, in offshore outsourcing the transaction costs are almost as significant as the production costs. Production costs savings appear to explain why firms outsource onshore in the first place (Ang and Straub, 1998). They explain why a firm will decide to outsource offshore (the salary of an Indian programmer is approximately one-fifth that of their US counterpart (Heeks, 1996)). However, they do not explain why a buyer will select one low-cost country rather than another. For example, an Indian company might demand $8.5 per hour and a Chinese company $7.5 per hour. There is a 15% difference from the supplier’s point of view. However, from the customer’s point of view, where the labour costs only represent approximately 10–15% of overall offshore Table 2 Monthly personnel costs ($) of software development according to employee status Cost element Per contractor monthly costs Wagesb Overhead and profitc Total man hour charges Hourly rate (175 h/month) Per diemf Per project monthly costs Travel expenses to offshore siteg Telephone status callsh Domestic/H-1B contractor/Outsource Offshore a B1 contractor on-site Low Medium High Low Medium High 5800 5800 11 600 66 N/A 450 2700 d 3150 18 1000 700 4200 d 4900 28 1500 950 5175 d 6125 35 2000 350 2275e 2625 15 N/A 700 3675 e 4375 25 N/A 950 4650 e 5600 32 N/A N/A N/A N/A N/A N/A N/A N/A N/A 600 200 900 400 1200 600 Low Medium High 3500 3500 7000 40 N/A 4600 4600 9200 53 N/A N/A N/A N/A N/A a: India is used as the offshore country in this table; b: Hourly charge for ERP contracts (e.g. SAP, PeopleSoft, BAAN, etc.) can add 100–200% to this charge.

Source: Heeks (1996). Analysis of the role of transaction costs in supplier selection outsourcing costs, the difference is only 1.5–2%. At this low level of production cost difference the difference in transaction costs becomes much more important. An immediate implication is that governments and their firms in countries such as China should be less concerned with holding down production costs by keeping wages low and more concerned with minimizing the transaction costs which potential buyers and sellers may incur. The next section develops a framework that will enable China and India to be compared in terms of potential transaction costs. Developing a framework for comparing transaction costs The first step is to classify the various factors buyers consider when choosing a vendor. There are many different versions (e.g. Terdiman, 2002). The most significant factors are discussed below. (1) Production costs differentials. These have been discussed above where it was noted that, where one low-cost country is competing with another (e.g. China versus India), then these are likely to be trivial. (2) Language barriers. Where these are low, communication costs fall and there is less misunderstanding, which leads to lower uncertainty. (3) Government support. Incentives reduce production costs and attract more investment into the sector. High-level commitment by government may reduce the opportunistic behaviour of vendors. (4) A plentiful IT professional pool and education system. This guarantees the availability of human resources, which reduces the uncertainty and avoids increases in production costs due to labour shortages. (5) Quality. This is the basic requirement of a product or service and reduces monitoring costs. (6) Culture fit. People prefer to work with those who come from the same culture for a reassuring atmosphere. It is a transaction costs barrier for others. It is easier to communicate, understand and monitor and thus reduces contractual costs. There is more chance of building a trust relationship and this reduces the probability of opportunism. (7) Political stability. This means lower uncertainty. (8) Financial robustness. If it is unlikely or costly for suppliers to declare bankruptcy this will prevent them appropriating the quasi-rent. Customers can avoid the shifting costs of finding new vendors as well. Therefore, transaction costs are reduced. 59 (9) Process and methodology (CMM). By means of standardizing processes and third party monitoring, the uncertainty/complexity is reduced. (10) Supplier reputation. Giving consideration to reputation in source selection can reduce opportunism by sellers, thereby reducing the uncertainty and thus the transaction costs for buyers. On the supplier side, reputation building is an investment in some kind of asset specificity that will increase their transaction costs. Although reputation has a high and durable value if the supplier maintains it appropriately, it is also easily lost if the supplier makes a mistake. (11) On-site presentation. This could reduce the transaction costs for buyers. However, it increases sellers’ transaction costs by higher site specificity (one kind of asset specificity). (12) Expertise. Hardware/Software: a Windows–Intel platform, as well as common developing tools and skills, produces lower asset specificity for suppliers. Equipment such as mainframes could be provided by clients or accessed through the Internet, thereby reducing asset specificity for suppliers as well. However, some special skills or business knowledge required by a customer may only be useful for that specific customer. This will increase asset specificity on the supplier side. (13) Commitment of outsourcing. This increases asset specificity. (14) Experience/Heritage. This increases human capital specificity for the supplier side. (15) Proven offshore methodology. This reduces uncertainty for the client side but increases asset specificity for the supplier side. The above analysis indicates that, except for some fundamental requirements such as delivery capacity, quality and infrastructure, most of the selected criteria relate to transaction costs. There are two inferences. First, clients mainly focus on reducing their transaction costs, which, given the choice to go offshore in the first place, is the main theoretical principle underlying the criteria for selecting offshore outsourcing suppliers. Second, clients tend to choose suppliers that have an asset specificity that is higher for offshore outsourcing or for a specific customer. Both buyers and sellers will benefit from understanding this principle. By going through the activities linked with market transaction costs buyers could have an overall view of how to choose offshore suppliers and then find an optimal balance of criteria rather than use each criterion separately. By simplifying the complex customer criteria into one fundamental issue, namely reducing transaction costs for their clients, sellers could focus their efforts on this key consideration. The concern in this paper is with sellers. Qu and Brocklehurst 60 The second step is to examine the nature of these transaction costs. There are two important factors to bear in mind. First, from the perspective of the transaction participants, transaction costs exist on both the buyer and seller sides. For example, both buyers and sellers need to pay the costs for negotiating and writing contracts. For a one-off market transaction it may be true that it is only the buyer that needs to worry about opportunism. However, for a set of transactions bound in an outsourcing contract of 3 years, which is termed relational contracting in transaction costs theory, both the buyer and seller need to worry about opportunism. Second, from the perspective of cost management, transaction costs can be divided into three types. (1) Type 1 costs, which are termed compulsory costs, are those costs that both buyers and sellers have to pay, for example communication labour costs for both sides, decision costs for buyers and special skills/knowledge-building costs for sellers (asset specificity). (2) Type 2 costs, which are termed complementary costs, are those costs that one side pays and the other side saves, for example searching costs: if a seller pays for marketing and information publishing costs, its buyers will save their search costs. Although both the seller and buyer could invest in this, the returns are asymmetric. The investment paid by clients has little scrap value for them after they change the supplier or at the end of the contract. On the other hand, the investment paid by suppliers may accumulate value for them after the end of contracts, due to enhanced reputation and awareness. (3) Type 3 costs, which are termed win–win or lose– lose costs, are those costs that both buyers and sellers would either save or pay, for example negotiating and monitoring costs. If buyers and sellers trust each other both sides will save money Table 3 and, the deeper they trust each other, the more they can save. This is the win–win case. On the other hand, if buyers and sellers suspect each other both sides have to pay more for negotiating and monitoring and, the more suspicious of each other they are, the more they have to pay for this. Table 3 gives some sample items of transaction costs using this three-fold classification. This section has examined the various factors involved in buyer selection of an offshore supplier and found that they are almost entirely related to transaction costs. The section then classified how these costs may differ: compulsory, complementary and win–win. The study is now in a position to compare China and India in terms of transaction costs. Comparing China with India Table 4 has been compiled from a range of sources and shows how China compares with India in terms of competitive advantage as offshore suppliers of IT outsourcing. At first sight China appears to compare very favourably. China comes out very close to or ahead on 27 of the 32 factors. The five where it compares unfavourably are highlighted and they can be reduced to two: education and training and the legal framework for information and communications technology (ICT) development. It has already been noted that education and training are being addressed as a top priority. What then of the legal framework? This involves two aspects: legal contracts and intellectual property rights. Legal contracts matter because, if the average contract length is over 3 years, then relational contracting is the fundamental instrument of offshore outsourcing and such contracting is inevitably based on the buyer country’s, seller country’s and international legal systems.

They seek to minimize uncertainty and, thus, reduce transaction costs. If a buyer has anxieties about the legal system of the country of a seller then this makes it very difficult to set up a contract. For historical reasons India’s legal system fits better with the Western world, where outsourcing clients come from, than does China’s legal system. There is also much concern in the West about intellectual property rights protection in China. This also raises transaction costs because buyers need to spend more effort in contract writing and intellectual property rights management. However, the situation is improving. The Chinese Government’s assignment of an $800 million procurement contract with Microsoft is a milestone in this respect. Furthermore, the challenge of improving the legal framework is being addressed. Since its entry into the World Trade Organization in 2001 China has been adapting its legal system to fit in with the international business community; but there is a long way to go. What other factors, which are not disclosed in Table 4, might put China at a disadvantage in terms of transaction costs? Qu and Brocklehurst 62 One obvious factor lies in language and culture. The language barrier and culture fit are two of the most serious obstacles preventing China from entering the offshore outsourcing supplier market (Liu, 2002). On the other hand, language is an immense advantage for India. English is the official language in business and education in India and that is perfect for the US and UK markets. But what about the Japanese market? In comparison with India, China ought to be more compatible culturally and linguistically with the Japanese market and, in addition, has a geographical advantage. However, it appears this is still not enough. India provided $300 million worth of offshore services to Japan in 2001, which was 4% of its total revenue. At the same time China made approximately the same from Japan (approximately $300 million), but that represented 42% of its total revenues (China Software Industry Association, 2002). Even though China has substantial advantages in culture, language and geography, it seems it still cannot beat India in the Japanese market. This tells us two things. First, culture fit and language barriers are indeed very important for offshore outsourcing. Because of these advantages alone China has at least managed to compete with India on an equal footing in the Japanese market, even though they are not in the same league in terms of the global offshore outsourcing market. Second, there Table 5 must be some other drawback hindering China’s performance, otherwise China would dominate the Japanese offshore outsourcing market in the same way that India dominates the US and European market. What Table 4 does not show and what is crucial is the structure of the industry. One of the main alleged weaknesses prevailing in China’s software industry is that the size of most software companies is too small to win offshore contracts, as noted above. Recall also that the low rate of CMM certification remains an issue and that these two factors are linked in the eyes of the Chinese Government. However, a comparison between the top 20 Chinese and Indian software companies suggests that this view may be mistaken. Tables 5 and 6 indicate that, in size terms, the top 20 Chinese and Indian software companies are very similar. In addition, 18 of the top 20 Chinese software companies are listed on the Chinese stock market, which guarantees them access to plentiful capital. So, at an industry level, it cannot be said that China’s software companies are too small to deal with offshore outsourcers. The top 20 companies in China contribute 37% of China’s software and service revenues, whereas the top 20 in India contribute 35%. However, the software exports data in Table 7 demand attention.

China’s top 20 software export companies contribute only 13% of China’s total software/services exports and their mean export revenue is just $4.75 million. Considering that they are approximately the same size this implies that most of the largest software firms in China have simply neglected the export market. They have preferred to concentrate on the very large domestic market. The Chinese software and IT services industry is only approximately 5% smaller than India’s, but its exports are as little as one-tenth of those of India (www.ccidnet. com, www.nasscom.org and www.mii.gov.cn). Furthermore, the top three Chinese software export companies in Table 7, which earn 78% of the top 10’s export revenue and produce 15% of China’s total 64 software/services exports, tend to sell software bound with their hardware products rather than providing offshore outsourcing services. From a pure offshore outsourcing perspective the biggest Chinese provider is the Eusoft Group, which achieved $6.1 million in export revenue in 2001, which is only 1% of that of the biggest Indian provider. Although there are no detailed data available on each Chinese company’s export revenue, by referring to Table 7, where the tenth largest exporter’s revenue is just $1.3 million, it can be inferred that 87% of China’s software exports have been won by small software companies that have individual exports of below US$1 million. If it is assumed that the mean annual export revenue of China’s companies is $600 000 (which is in fact the mean revenue of all Chinese software companies, so the actual export figure is likely to be much lower than this) and this is compared with the $2.1 million mean offshore outsourcing contract (ComputerWire, 2001a), it is clear that the transaction frequency in each outsourcing contract of China is quite low. This means, from the frequency perspective, that the transaction costs of outsourcing to China are higher than average. Engaging in many small transactions is costly: a $12 million contract incurs fewer transaction costs than three small ones of $4 million each. Moreover, transaction costs theory argues that trying to establish a set of independent companies using a common brand name – the Chinese Government’s ‘software export cluster’ – is flawed. This is because it is impossible to prevent the ‘free rider problem’ on the brand name (Douma and Schreuder, 2002). In addition, there are always problems of ensuring the standardization of quality and the monitoring of effort where a number of firms work together to supply a client. It is important to determine why the largest Chinese software companies fail to win offshore outsourcing deals in the same way that Indian companies of similar size manage to do. Does China’s domestic market provide higher profit margins than the offshore outsourcing market? This is unlikely since the margin of Indian offshore service providers is as high as 30% and the average margin of China domestic software industry is only 15% or less (China Software Industry Association, 2002). The domestic market may be large, but it is not more profitable than the export market. There are in addition two factors that are not brought out by the data in Table 4 and both of these put China at a disadvantage. First is the on-site presence issue. By reducing the transaction costs for customers, on-site presence is very important for offshore outsourcing. India made 46.5% of its exports revenue from on-site delivery in 2001 (Table 1). There are at least 100 000 Indian IT professionals working on customer sites, while for China the corresponding number is negligible. Apart Qu and Brocklehurst from several small sales offices in the USA there is almost no deployment of on-site delivery workforces from China. In fact, most of the Chinese software export business is made up of small-size subcontracted projects negotiated with the middlemen, rather than real offshore outsourcing deals. According to Chen Yuhong, director of CSS International, the second largest offshore outsourcing service provider of China, most Chinese suppliers are not even aware who the end-users are (China Computer World, 2002). Second is the issue of marketing. Marketing investment, which is paid for by the suppliers, can reduce transaction costs such as searching costs for customers. However, Chinese suppliers have not done much in this respect. For example, at the OutsourceWorld London 2002 exhibition and conference only two of the 79 participating companies came from China, as opposed to 26 from India, 19 from Pakistan and eight from Russia (OutsourceWorld London Yearbook, 2002). IT managers in the UK receive a deluge of selling calls from Indian and Pakistani suppliers, but rarely from Chinese suppliers. In a survey conducted by the authors among the members of the National Outsourcing Association and IT professionals in the UK, not a single respondent from 28 responses knew any supplier from China. It is also very difficult to find trustworthy information about Chinese suppliers, particularly in English, through the Internet or other media. India has set up an efficient organization, the National Association of Software and Services Companies (NASSCOM), which provides abundant quantities of reliable information, including individual supplier profiles, through the Internet. It also builds up a network among Indian suppliers. In contrast, the China Software Industry Association, as a governmentmanaged organization, provides little helpful information for offshore customers. This inevitably pushes up the transaction costs for companies considering outsourcing to China. The vendor has to be seen to have a track record in the relevant area and to have proved itself in some way. Despite this, the assessment of track records sometimes seems somewhat arbitrary and based more on anecdotal evidence and information supplied by the vendors themselves rather than obtained independently (Michell and Fitzgerald, 1997). NASSCOM has been very adept at supplying this information. This saves transaction costs for both customers and Indian suppliers. China should learn from this and build a similar organization. Ultimately, effective long-term networking between a buyer and vendor requires the building of trust. Trust and networking are effective measures for reducing transaction costs. According to Williamson (1975), not everyone behaves opportunistically, only someone sometimes. If the buyer and seller trust each other, the transaction costs of preventing opportunism will be reduced significantly. Analysis of the role of transaction costs in supplier selection Trust is infectious. People tend to trust someone that other trustworthy people trust. Networking is a good, perhaps the best, vehicle for building such mutual trust. Consequently, associations of clients, vendors or both are a good way of reducing transaction costs. Thirty years of isolation has meant that China has less networking opportunities with the Western world than India. Millions of Indians have lived in North America and Europe for years and many of them are successful professionals, particularly in the IT industry. Chinese, from the mainland at least, have only begun to visit the USA and Europe for lengthy periods since the 1990s. Most of them are still working in junior positions, two or three notches lower than the well-established Indians. Thus, the Chinese network in the USA and Europe is much weaker than that of India and this also increases the transaction costs for outsourcing to China. The concluding sector considers what the policy implications might be. Conclusions: outlining a policy agenda This paper has demonstrated that transaction costs assume a much greater importance relative to production costs for offshore outsourcing as compared to its onshore cousin. (It is not possible to be precise about the quantitative relationship between transaction and production costs – that requires further work.) Moreover, when it comes to the choice of offshore supplier, transaction costs are critical. Yet the difficulty remains that transaction costs are not as transparent as production costs, nor can they be so precisely delineated by a contract. What this paper has accomplished is the rectification of this situation by bringing together various sources of published data to reveal where China fails to compete with India as an outsource provider. Joint ventures are often not needed with onshore outsourcing because the transaction costs are so low; but with offshore outsourcing joint ventures become more viable. Such ventures have been hampered in China because of the legal difficulties described above. Nevertheless, they are starting to grow. In fact, more than 100 multinational companies are using this model in China already (Science Innovation and Made in China, 2002). Lucent has set up two research and development centres in Shanghai and Beijing hiring 500 IT professionals. SAP has set up a research and development centre in China with approximately 150 employees. Initially this was just for Chinese localization of SAP R/3 for the China enterprise resource planning (ERP) market, but it has since become a low-cost development facility for SAP Global. IBM has set up a joint venture in Shenzhen, hiring 130 programmers. Initially this was for localizing IBM software products for the Chinese market, but now 65 it has become an IGS offshore outsourcing facility working on mainframe maintenance for Hong Kong Telecom. HSBC has moved its call centre from Hong Kong to Guangzhou. Others, such as Motorola, Microsoft, NOKIA, NEC, HP, Erickson and Intel, have all set up research and development centres in China hiring more than 100 professionals. These are clearly encouraging trends for China, but what else should the Chinese Government do? Some of what is being done, in particular around education and pursuing CMM certification, is along the right lines, but other measures are either irrelevant (concern over production costs) or counterproductive. The first and most obvious point is to cease trying to promote software export clusters and try instead to encourage the large Chinese software companies to enter the offshore outsourcing supplier market and allow small outsourcing suppliers to develop naturally. It is unrealistic to expand company size first and then hope to get more business. Second, both the Chinese Government and offshore service suppliers must enhance their marketing and sales force by going abroad to customer sites. They need to merge and acquire USA- and Europe-based outsourcing suppliers or set up joint ventures with them or at least set up branches hiring local sales forces. The Chinese Government should invest in setting up an organization similar to NASSCOM in order to provide free and reliable information to potential foreign customers. The Chinese Government should also invest in overseas advertising in order to improve the international reputation of China and at least let people know more about China. The Chinese Government, as a warrantor or a trusttransferring middleman, could help Chinese suppliers build up their reliability and reputation. Third, they should enhance their on-site presence. It may cost more for suppliers, but there is no other choice. Nearly half of Indian IT exports come from on-site delivery. Hiring overseas Chinese students is a possible solution. Fourth, the Chinese legal system is a big concern for offshore outsourcing clients. A reliable and efficient legal system is fundamental for contractual businesses such as outsourcing. It is impractical to wait for an improvement in the Chinese legal system. Registering companies in the USA and Europe for dealing with customers is a feasible alternative. Fifth, it is important not to lose their domestic outsourcing market to Indian companies. The huge domestic market is the only absolute advantage that Chinese firms possess against their Indian rivals. By developing a domestic outsourcing market, Chinese suppliers can obtain business knowledge, gain project management experience and build reference and reputation, as well as grow their companies. 66 Sixth, they need to focus on special projects and regions where language or other barriers are not too high, such as Japan, the European continent and Hong Kong, where the English language is not as crucial as it is for the US market. Seventh, Chinese suppliers should put more effort into business process outsourcing businesses, where no-one has yet to dominate, rather than IT outsourcing where India is already dominant and enjoys first mover advantage. In particular, Chinese suppliers have the chance for providing business process outsourcing services for the numerous foreign investment businesses that already exist in China and then to stream up to their headquarters offshore. Finally, now that China has entered the World Trade Organization many multinational companies are going to seek to do business in China. Most of them, such as insurance, retail, telecom and bank firms, will have to negotiate with the Chinese Government in order to obtain market entry permits. Others, such as Microsoft, IBM and GE, who want to win huge government purchase contracts from China, also need to negotiate with the Chinese Government. All of these multinational companies have considerable offshore outsourcing business to allocate. As a trade exchange, the Chinese Government could persuade them to outsource to China. For example, Microsoft has just signed an outsourcing contract of $800 million to China for the next 5 years. This will greatly accelerate the growth of China’s offshore outsourcing service business. There is no question that China has the potential to compete with India and even surpass India in certain markets as a vendor of IT services, but there is not much time. Policy changes are required before this market matures and the window of opportunity closes.
