基于电信重组后新市场格局下网间互联的非合作博弈分析

Game Analysis of Telecom Network Interconnection Under the New Market Structure

立足于我国新一轮电信重组后形成的市场格局,结合我国电信网间互联质量低下的现实,本文对我国电信网间互联的问题进行探讨。通过设计一个两阶段博弈模型,本文分析指出,运营商在非合作的情况下进行互联博弈,(不联通,不联通)形成一个占优战略均衡,而且当某个运营商的市场份额高达一定的值时,纳什均衡(不联通,不联通)是帕累托有效的;当运营商网络资源相差不大时,纳什均衡(不联通,不联通)不再是帕累托有效的,局势(联通,联通)是对纳什均衡(不联通,不联通)进行帕累托改进的结果,同时,这个局势也意味着社会福利最大。进一步的分析发现,当运营商的市场份额相等时,局势(联通,联通)的稳定性最强。进而指出政府的管制目标是促进合作局势(联通,联通)的形成,并通过平衡市场力量,设计罚款机制等措施保证其稳定性。

Based on the market structure formed in the new round of reconstruction,combining with the fact of low quality of the telecom network interconnection,this paper makes an analysis on the problems of the telecom network interconnection.By designing a two stages game model,this paper points out that in non-cooperative game,(disconnect,disconnect) forms a dominance equilibrium and when an operator's market share is up to a certain value,the equilibrium (disconnect,disconnect) is pareto-effective.When operators' network resource is almost the same,the equilibrium(disconnect,disconnect) is no longer pareto-effective.(Connect, connect) is the pareto improving result of(disconnect,disconnect) and at the same time it means the maximum social welfare.Further analysis finds that when operaters' market shares equal,(connect,connect) has the strongest stability.And it is further pointed out that the regulation aim of government is to promote the formation of(connect,connect) and by balancing the market power,designing the penalty mechanism to guarantee its stability.
