Evolutionary Game Analysis of Opportunistic Behavior Based on Supervision Mechanism in Purchasing Alliance

摘要

Under asymmetric information environment, the evolutionary game model of opportunistic behavior in purchasing alliance is established with supervision mechanism. Relevant conclusions are proved and verified by means of numerical simulation. The result shows that when all purchasing enterprises introduce supervision mechanism, whose cost is less, and the opportunistic behavior proportion is lower, penalties is moderated, opportunist and reciprocitarian will coexist in purchasing alliance. On this basis, the opportunistic behavior is more effectively restrained by moderating adjusting purchasing enterprise and alliance factors, such as enterprise strength, cooperation degree, cooperation intention, cooperation risk and transparency.
