Purpose – The objective of this paper is to investigate the effectof asset specificity, the level of information sharing, the importanceof information sharing, and an integrated collaborative environment onsupply chain performance. Research design, data, and methodology - Data collection was implementedas follows: questionnaires were distributed to 250 companiesthat have business ties with Halla Climate Control Corporation. The empirical study to test our hypothesis was based on statisticalanalysis (using SPSS 18.0 and AMOS 18.0). The hypothesis of thispaper is that the asset specificity variable has positive effects on thefollowing variables: Level of information sharing, the importance ofinformation sharing, and integrated collaborative environment. Moreover the variables, the level of information sharing, and the importanceof information sharing are strongly influenced by the variableintegrated collaborative environment, and these when combined,have an effect on the dependent variable, supply chain performance. We tested our hypothesized model utilizing path analysis with latentvariables. Results - According to the results of our analysis, hypothesis H1,which tests whether there is a relationship between asset specificityand the integrated collaborative environment, is supported at the 0.01level. Hypotheses H2 and H3 were also confirmed, and asset specificityhad positive effects (+) on the level of information sharingvariable. The importance of the information sharing variable was statisticallysignificant at the 0.01 level. Hypotheses H4 and H5 positedthat the integrated collaborative environment variable would have apositive effect on the level of information sharing; the importance ofinformation sharing variable was strongly supported statistically, witha significant p-value below. Moreover, the level of information shar-ing (H6), and the importance of information sharing (H7) variablesalso had a statistically relevant influence on supply chainperformance. As a result, existence of a collaborative system betweencompanies would influence supply chain performance by strengtheningreal-time information access and information sharing. Thus, it is importantto construct a collaborative environment where informationsharing among companies and cooperation is possible. Conclusions - First, with rapid changes in the business environment,it becomes necessary for enterprises to acquire the right informationin order to properly implement SCM. For successful SCM,firms should understand the importance of collaboration with supplychain partners and an internally built collaboration system, which inturn will better promote a partnership commitment with suppliers aswell as collaborative integration with buyers. A collaborative system,as we suggest in this paper, facilitates the maintenance of along-term relationship of trust, and can help reinforce informationsharing. Second, it is necessary to increase information sharing overtime via a collaborative system so that employees of the suppliers becomeaware of the system. The more proactive and positive attitudesare towards such a collaborative system by the managerial group, thehigher the level of information sharing will be among the users. Successful SCM performance is achieved by information sharingthrough a collaborative environment rather than by investing only insetting up an information system.
