Game Analysis of Interfirm Cooperation with Three Modes of Supply Chains

In this paper we propose three modes of alliance structures of supply chains and discuss the cooperation mechanisms among enterprises firstly, and by analyzing the dyadic supply chains we apply the game theory to the research on cooperative relation among enterprises respectively for the three modes of alliance structures of supply chains, point out the conditions on which the supply chains can be set up and steadily keep up for a long time, and scientifically interpret the cooperative relation among enterprises.     

A Characterization for Dominant Strategy Implementation

We introduce a perfect price discriminating mechanism for allocation problems with private information. A perfect price discriminating mechanism treats a seller, for example, as a perfect price discriminating monopolist who faces a price schedule that does not depend on her report. In any perfect price discriminating mechanism, every player has a dominant strategy to truthfully report her private information.We establish a characterization for dominant strategy implementation: Any outcome that can be dominant strategy implemented can also be dominant strategy implemented using a perfect price discriminating mechanism. We apply this characterization to derive the optimal, budget-balanced, dominant strategy mechanisms for public good provision and bilateral bargaining.

A Study of Competition Matching Based on Principal Component Analysis among Supply Chain＇s Enterprises

Supply chain＇s strategy matching is the guarantee that supply chain can obtain the competitive advantage and achieve its whole strategic target, and competition matching among node enterprises is the bases of supply chain＇s strategy matching. Based on the methods of principal component t analysis, an algorithm of competition matching among node enterprises is proposed. The results show that this algorithm can scientifically and reasonably judge the matching degree of main competitions among node enterprises and offer the evidence for establishing supply chain＇s strategy.
