新成员的加入对供应商网络效率的影响分析

不断有企业进入或者退出供应商网络,网络中企业的效用和网络效率都会受到影响.本文把关系收益和竞争系数结合起来,构建了新的效用函数.并通过效用的比较分析,竞争系数对称时,新企业的加入会使网络效率增加的结论,并进一步给出了进入企业选择与中心企业或者与边缘企业建立关系所应满足的条件;而竞争系数不对称时,网络效率可能会降低.

Effect of the New Entrant on the Efficiency of Supply Network

In reality,firms may enter into or exit from the supply network,which may have an effect on the efficiency of the network and the utilities of firms in the network.In this article,firstly the payoff of tie and the competitive coefficient are combined,and a new utility function is constructed.Then,through comparing the utility,when the competitive coefficient is symmetrical,we can conclude that the efficiency of network will increase with the entrant of new firms.Furthermore,the conditions under which the entrant firm establishes ties with the core firm or the peripheral firm are also given.Whereas,when the competitive coefficient is asymmetrical,the efficiency may decrease.
