2013 International Conference on Management Science & Engineering (20th) July 17-19, 2013 Harbin, P.R.China Research on Utility Measure of Firm Tangible and Intangible Resources-Based on Utility Theory JIANG Yuan-zi,DONG Xue-yan,WANG Tie-nan School of Management, Harbin Institute of Technology, P.R.China, 150001. Abstract: The resource-based view of the firm (RBV) believes that resources are the foundation of enterprises’ survival and development. However, the resources investment of firms do not always achieve the expected output in practice, besides, there is not a good way to measure the utility degree of resources investment in the current study, which largely hinder the investors to allocate resources effectively. Thus, it is urgent to discuss the question of utility measure of the firm resources investment. In response to this gap, this study constructs a utility measure model of enterprises’ tangible and intangible resources based on utility theory, through the solution to utility parameters to calculate enterprise resources investment utility value, and finally takes Shanghai Automotive of China as an example to provide further analysis. Therefore, this study offers a tool for enterprises to measure resources investment utility that improves the feasibility and validity of using RBV to solve resource allocation problems in some extent. Keywords: intangible resource, tangible resource utility measure model, utility theory 1 Introduction The resource-based view of the firm (RBV) hypothesizes that resources are the necessary conditions to maintain the competitive advantage (Wernerfelt 1984; Barney 1991; Ray, Barney & Muhanna 2003)[1-3]. The endowment difference of firm resources is directly related to the status of their own in the market competition. Since the 1980s, scholars generally claimed that resources can be divided into tangible and intangible ones, and elaborated the material base which almost contains enterprise’s assets, equipment, human resources, etc determining the differences of competitive advantage and firm performance. However, it cannot explain why the firms in the same industry possessed the same or similar resources have significantly different performance and also cannot illustrate systematically the reason why the firms (such as state-owned firms) mastering trait of resources do not have good performance [4]. In order to achieve scale economy and Supported by the National Natural Science Foundation of China (71031003) 978-1-4799-0474-7/13/$31.00 ©2013 IEEE scope economy, an increasing number of enterprises obtain resources by mergers and acquisitions (M&Q) currently [5], and promote keen competitions in the market relying on their own resources advantages, such as the electric business price war in August 2012 which finally competing their bases of financial resources. All these examples indicate the importance of resources guaranteeing the enterprise working [6]. However, from the economics perspective, ‘the most investment is not always along with the best output’, it is unsure enterprises will have remarkable performance even they possess abundant resources, because prominent performance need the best fit of resources allocation [7]. While the premise of resources investment satisfies the matching condition is to measure the utility of resources input, which requires attention to the output effect of enterprise resources’ input. Based on the resource- based view (RBV), scholars constructed numerous theoretical models and research paradigms from different aspects about how to use enterprise resources to build competitive advantage and to improve the firm performance. Some scholars put forward some views on the relationship between resources and performance from qualitative perspectives[8], they study the construction of resources indicator system under the framework of the resources and their influence mechanism, others empirically examines the relationships between one resource or characteristic and enterprise performance (Barney and Muhanna 2004)[3-9], the rest explore whether input one resource or not from the aspect of game theory[10], the results of these studies are consistent with the resource -based view (RBV) (Barney and Arikan 2001)[11]. There is still neither an overall research integrated enterprise resources, nor researches on discussion about resource utility measure. In order to solve this problem, some scholars pointed out that the competitive advantage is the process of resources input and output systematically not just a single process of resource utilization[12] Therefore, it is necessary to consider the discussion of resources utility measure. However, there is not yet a good way to measure the utility degree of resources investment in the current studies. In order to further study the problem, this paper builds a utility measure model based on utility theory using the analysis on consumption utility for reference from the economics to discuss the problem of - 275 - utility measure on enterprises’ resources input. 2 Theory background 2.1 Resource-based view The resource-based view (RBV) is proposed by B.Wernerfelt in 1984[1], and then developed incrementally by scholars (Barney, Shuen, Teece, Peteraf, Pisano et al)[13]. This theory defines resources are the factor set that processed and controlled by enterprises in order to maintain the survival and development. Previous studies illustrated that enterprise resources are most important factors to compete the environment challenge and the base condition of making performance differences[14-15]. In the research of enterprise resources, RBV scholars discuss whether resources would contribute to the enterprise competitive advantage employing a resource heterogeneity approach whereby the resources characteristics are argued to be valuable, rare, inimitable and non-substitutable (Barney 1991)[2].However, some scholars later pointed out that it is not sure resources with the characteristics can contribute enterprise competitive advantage because the foundation of the enterprises is different that resources with the characteristics may not match the strategy and actual operation activities (Newbert 2008)[16], it’s necessary to discuss the utility measure before deciding whether firm resources should be invested from this perspective. To date, the academic circles still do not have a uniform standard to the definition or classification of resources. Some scholars insist that resources can be divided into tangible resources, intangible resources and ability (Hall 1992)[17], some scholars hold that intangible resources include ability (Jeremy Galbreath, 2005)[18]. It is difficult to identify a specific resource belonging to resources or capacity because of the ambiguous definition. On the basis of previous researches, resources are divided into tangible resources and intangible resources that is a paradigm widely accepted. In current studies, tangible resources have been an important factor influencing performance because of its controllability. Galbreath (2005) believes that scholars should consider tangible resources in the actual research on enterprise resource theory[18]. Not only can tangible resources bring high performance output directly and translate it into competitive advantage but also create duplicate disorder[19-21], which shows tangible assets are important factors influencing the enterprise performance undoubtedly, especially for those who rely on natural resources whose performance must be influenced by the availability, quality and quantity of physical assets. Tangible resources are the foundation of enterprises’ development, Galbreath (2005) assumed that intangible resources are the most important factors in the success of an enterprise[18]. According to this assertion, we can explain why enterprises with strong tangible resources (mass, abundant funds, etc.) do not have expected performance as well as explain the phenomenon of ‘fight against longer odds’ in market (such as early Wahaha acquired state-owned enterprise). Simultaneously, the enterprise capability theory holds that the root of the enterprise performance differences is resulted from the different enterprise ability (enterprise ability is closely related with the resource utilization of comprehensive knowledge and skill) differences[22], and capability is an important part of enterprise intangible resources in the light of the resource -based view (RBV)[2]. According to the current researches, it is a perfect approach to solve the bottleneck through enterprise intangible resources view to discuss its own hardware problems and from the perspective of system to balance enterprise tangible and intangible resource. Nevertheless, the intangible resources are duality, enterprises are trapped into a competitive disadvantage[23] also collapse (such as SanLu powdered milk production enterprise’s collapse). Therefore, it’s necessary and urgent to discuss the utility measure before deciding firm resources investment. 2.2 Utility theory Utility theory is proposed by Daniel Bernoulli in the famous ‘saint Petersburg paradox’ in 1738 [24] and the theory has been widely used in the field of decision-making. Utility is the value measure according to the preference relation, and relationships among the research objects can be quantified through the concept of utility which makes the complicated problems of value measure comparative in a unified standard[25]. What the concept of utility in economics is the degree of satisfaction of consumers after consuming goods or service[26] generally discussed from the main body and object two aspects. Utility refers to the satisfaction of people gained from their own behavior from the main body of consumption and the ability goods meet peoples’ need or desires from consumption object speaking. Economists use the concept to explain how rational consumers allocate their limited resources to consumption goods bringing the most satisfaction in practice. The concept of utility is a kind of subjective value from this aspect which shows different attitudes of decision makers to risks and consequences of investment. Utility function is a quantitative expression of the subjective value. Utility value has both objectivity and subjectivity[27]. Because the resources investment of investors the same as the consumption of consumers and the performance satisfaction degree of resources investment the same as the consumer do, it is reasonable of using the utility theory and utility function (value) to solve the utility measure problem of enterprise tangible and intangible resources, which is also the point and theoretical basis of this article. From the current research, common utility function is usually divided into linear function, semi logarithmic function and constant elastic function three kinds of model [28]. This paper adopts the semi logarithmic function proposed by Yanzhang Wang (1987) in the fuzzy utility function [29],and the utility function should meet the following requirements from the qualitative study of economic activities: - 276 - xi → u i 1 when xi = ∞ (2) f → 0 when xi = 0 2 (3) df > 0, d f < 0 dxi dxi (1) f: 3 Measure of firm resources Tangible resources are the matter elements including enterprise equipment, workshop, capital, raw materials, number of staff, product revenue, profits, industry monopoly, ect., Elements of enterprises directly supporting their market behaviors and bringing direct output which can be quantified[30]. Aboody, Barth, Kasznik (1999) studied the fixed assets having significant positive influence on the enterprise performance[31]. Hay (2001) empirically examined the relationship between market share and profit though 318 enterprises samples[32]. Following Bharadwaj (2000) and Hay (2001), this paper uses fixed assets, market share two indicators to measure enterprise tangible resources. Fixed assets refers to the relative fixed physical resources including plant, equipment, ect. Market share reflects the sales situation and monopoly degree of enterprise products. Intangible resources are the basic conditions of enterprises to gain the continuous competitive advantage[26], and they include enterprise brand, patents, property right, trademark, copyright, technology, innovation, cultural elements ,ect.[33]. Itami and Roehl (1987) pointed out that all successful enterprises have a common characteristic is that staff skill level and enterprise reputation[34], and Richard Hall (1992) empirically examine finding match the assumption through survey on enterprise CEOs[20]. Belderbos, Carree and Lokshin (2004) also empirically tested that different types of R&D cooperation will produce different innovation performance[35]. Following Richard Hall(1992), Galbreath (2005) and Belderbos (2004), this study utilizes staff education level, research and development (R&D) spending and intangible assets three constructs to measure enterprise intangible resources. Staff education level (the ratio of employees possessed bachelor degree or above accounted for the total employees) is a reaction of staff skills and learning ability[36]. Research and development (R&D) spending reflects enterprise’s innovation level, and this construct is also the most commonly-used index to measure enterprise intangible resources in the existing research. Intangible assets mainly refer to enterprise brand, reputation, patent, copyright, trade secrets, relational capita, ect. 4 Research models 4.1 Model design Accordingly, the concept of utility refers to the satisfaction degree of consumer consuming goods. From the perspective of whether a kind of goods would produce utility depends on two conditions: one is the consumption desire and the other is the ability to satisfy consumers’ desire of goods. In firms whether the enterprise resources would produce utility also should meet two conditions: the investors have investment preference to the resources and the resources investment could promote effectively the performance of enterprises. Therefore, we can measure the resources utility value and the maximize resources matching condition according to the two conditions. This paper construct antecedent hypotheses following resource based view and consumer utility: (1)Enterprises invest resources with certain expectation. (2)Enterprises are person bounded rationality, namely enterprises are between complete rationality and irrationality in practice. (3)Enterprises have investment expected preferences to resources. (4)The utility of enterprises gained is different even with the same condition. (5)Enterprises prefer to invest resources can obtain higher utility value. (6)Employees are always willing to work in organization with higher utility value. Utility function can show the utility value of one kind of commodity combination. Assuming that a consumer only consumes two kind of commodity then the utility function can be expressed as: U = f ( x1 , x2 ) (1) x1, x2 are the amount of two kinds of commodity in formula (1), U is utility level. This study introduces utility theory to the measure of enterprise tangible and intangible resources, utility is understood the contribution measure of resources to the enterprise performance, the more the utility value the grater contribution of resources to the development of enterprises. When the utility value are maximum respectively resources investment are at the best matching condition. If designing the measure function of enterprise tangible resources and intangible resources based on the utility theory, the commodity combination becomes resources investment combination of enterprise tangible and intangible resources, the different combination of resources result in different contributions to enterprise performance, while the best combination produce the maximal performance. What we study in this research is enterprise tangible and intangible resources, whose measure should also consider such elements as resources investment structure, investment preference , the investment price and demand intensity. Thus, the basic formula [29] was adopted : = u - 277 - m ∑ wn (1 − e n =1 − csn d n pn ) (2) In formula (2), wn is the investment preference weight coefficient of nth kind of resource (n = 1 tangible resources, n = 2 intangible resources), and wn≥0, Σwn =1 (if one is f , the other is 1-f ), the parameters reflect the value degree of investors to different kinds of resources and it decide the preferences degree and the maximal possibly funds to resources. dn is the demand intensity of enterprise resources stems from previous investment and the current need of enterprise as well as combined with decision makers’ investment interest preferences, psychological factors, it decides the actual resources investment. pn is the price of resource n (or related price index ). sn is the share of enterprise total investment allocating to resource n, also the rate of resource n investment account for the total investment, and sn≥0, ∑sn=1. c is the total spending of enterprises. Each parameter symbol and its implication see tab.1. Tab.1 Parameters of the utility function and its implication Parameter Implication symbol wn wn c ) d n pn sn = c(d n pn − wn c) (d n pn ) 2 ln( Formula (8) is the structure function of resource when enterprise resources allocation utility is at maximum condition. The significance of the formula lies in which can reveal quantitatively the degree of resource investment and how investors make the limited resources to allocate perfectly. 4.2 Parameter solution According to section 3.1, this paper solves the utility function parameters in tab.1 as following. wn is the investment preference weight coefficient of resource n which is certain subjectivity, this study uses the investment quantity of each resource accounting for the total quantity of resources, such as formula (9). And ri is the investment quantity of resource i, ∑ri is the total investment quantity of resources. the preference weight coefficient of resource n dn pn sn the demand intensity of enterprise resource n price of resource n or related price index the share of enterprise total investment allocating to resource n c the total spending of enterprises So, the utility of enterprise tangible resources and intangible resource can be measured by constructing the following goal programming function based on utility theory. m ∑ w (1 − e u = n =1 m ∑s n =1 n n − csn d n pn ) (3) =1 In order to make the utility maximal, structuring Lagrangian function: = L m ∑ wi (1 − e − csn d n pn m ) + λ (1 − ∑ sn ) (4) = n 1= n 1 cs wn c − dn pnn ∂L e= = −λ 0 ∂sn d n pn (5) m ∂L = 1 − ∑ sn =0 ∂λ n =1 cs wn c − dn pnn λ= e d n pn According to the above formula we can obtain: ln( wn c) − ln(d n pn ) − ln l sn = c / (d n pn ) cs wc − n Make λ = n e dn pn to formula (7): d n pn (6) (8) wn = ri (9) n ∑r i =1 i dn is the demand intensity of enterprise resource n which is certain predicted, in this research, we use the change quantity of resource in year t and t+1 accounting for the total change quantity of all the resources, such as formula (10). dn = � ri n = rt +1 − rt n i i i t +1 t =1 i= i 1 =i 1 �∑ r n ∑r (10) −∑r pn: parameter uses related price or price index to measure. c: parameter uses the total investment expending to measure. sn: parameter can be calculate by the value of wn , dn, c and formula (8). 5 Algorithm analysis In order to further use the model constructed to measure the utility value of enterprise tangible and intangible resources, this section take Shanghai Automotive (stock code: 600104) as an example to utilize the model. The data are from the enterprise annual report and this section compare the data of 2008 and 2011 in order to analyze the results easily, so collecting four years data from 2007 to 2011.As the second section of this paper, data in tab.2 is calculated difficultly because of non-unified standard, this study uses formula (11) to make transformation of dimensionless to the actual data.

This paper selects data of 2007 for the base data for the convenience of calculation in this algorithm analysis, then make the data in the table 2 dimensionless based on the formula (11) and the results are in tab Data in tab.3 is calculated through data in 2007 as period base and on the basis of the real resources value in 2007-2011 of Shanghai Automotive. Then wn, and dn is calculated based on the formula (9) and (10), pn utilizes the price index of corresponding year, c uses the total value of resources and sn can be calculated according to formula (8), lastly the value of resources can be obtained through formula (2). Results see tab.4. The result of different indicators are listed in Tab.4. The result shows the degree of intangible resources investment preference in 2011 declined compared with the one in 2008 longitudinally, which suggests the consciousness of emphasizing on intangible resources in Shanghai Automotive is being strengthened. However, the demand intensity and investment allocation coefficient of tangible resources were increased in 2011, which shows the most parts of resource were allocated to tangible resources in practice. The total utility value in 2011was grater than the value in 2008, and the utility value of intangible resources in 2011 was increased compared with the value in 2008 while the utility value of tangible resources declined in detailed description, yet the declining degree is less than the increasing degree of intangible resources, Which indicates that the real utility value of intangible resources is grate even the resources investment of intangible resources is less than tangible resources. This result is in accord with the real development condition of Shanghai Automotive and the view of ‘high resource input may not have high efficient output’. Therefore, Shanghai automotive can increase the intangible resources investment and slow the tangible based on the utility theory analysis. The resource utility value is measured through the algorithm analysis, providing resources utility measure method theoretically and solving the practice problem how to decide investing one resource. 6 Conclusion - 279 - Resources investment allocation does not always obtain the best utility value because the unique advantages of tangible and intangible resources cannot be quantified effectively in the practice which hinders the roles of resources advantages. This paper constructs a utility measure model and makes solutions to calculate the utility value of enterprises’ tangible and intangible resources based on utility theory, and takes Shanghai Automotive of China as an example to further study. These findings have important academic and practitioner implications which are then discussed. Theoretically, this paper provides scholars with a new perspective to calculate the resources utility value based on utility theory in economic, which enriches the resource-based view (RBV) and improves the feasibility and validity of using RBV to solve resource allocation problems. In practice, this article provides a train of thought as reference and a tool to quantify the utility value of enterprise resources, which benefits the allocation of enterprise resources. And enterprises can compare various resources investment utility value of different years with their own longitudinally as well as with their competitors horizontally. Therefore, it is useful to regulate effectively the investment allocation and improve the resource utilization efficiency in the actual operation. But this article also has some limitations, the solution to the parameters of utility model obtained by the annual report, this paper does not presents detailed analysis about the data in different industries and enterprises which presents an opportunity for further research to quantity the value of resources matching.
