摘　　要：考察内生网络环境下局中人之间的局部策略互动,网络中的局中人只与直接邻居进行协同对策.网络生成的过程中,建立连接的费用是异质的(具有两种水平),与采取有效行动的局中人建立连接时执行高水平费用,与采取风险占优行动的局中人建立连接时执行低水平费用.在异质连接费用的情形下,首次较为完整地给出了均衡网络的结构特性和局中人的行动选择,并分析了费用参数对均衡结果的影响.In the context of endogenous network formation, players can only play coordination game with their direct neighbors. In the network formation process, the cost of link formation is heterogeneous （with two levels）, and players would bear high-level costs when establishing links with players who choose an efficient action, and would bear low-level costs when establishing links with players who choose a risk-dominated action. In the case of heterogeneous link costs, the paper firstly gives an explicit description of the nature of network structure and players＇ choices in the equilibrium outcomes, and has analytically studied how the cost of link formation affecting the equilibrium outcomes.
