网络型市场结构下企业Cournot均衡产量决策研究

Cournot Equilibrium Output Decision Research in Network Market Structure

本文提出的网络型市场结构不仅克服了传统市场结构分析中割裂产业间联系的缺陷,同时也修正了供应链中忽视同行业之间相互作用的弊端,并进一步提出了网络型市场结构一般模型。进而,构造了两个具有代表性的"一市场两产业三企业"网络型市场结构模型,从(竞争,竞争,竞争)、(竞争,合作,合作)、(合作,合作,竞争)及(合作,合作,合作)四种策略组合对网络型市场结构下Cournot均衡产量和传统市场结构下Cournot均衡产量决策进行了对比。得出,网络型市场结构下企业Cournot均衡产量小于传统市场结构下企业Cournot均衡产量的结论,并通过算例对该结论进行了验证。

Network market structure overcomes the disadvantage that traditional market structure dissevered relationship among different industries, and amends the fault that supply chain omits the reciprocity in same industry. General network market structure model has been brought forward. Then, optimization output in network market structure is contrast to traditional market structure from four different strategies, （competition, competition, competition）, （competition, cooperation, cooperation）, （cooperation, cooperation, competition） and （cooperation, cooperation, cooperation） in two representative network market structure models. The conclusion the optimization output in network market structure is bigger than in traditional market structure can been drawn. An example was given to prove the conclusion that been brought.
