摘　　要：制度作为社会系统的子系统,是一个具有小世界性和择优连接等特征的复杂网络,其演化需要产生各种连接成本.文中构建了基于小世界效应、连接成本和节点影响能力的制度网络演化模型;提出了制度网络演化的纳什效率策略及帕拉托效率策略;通过理论及仿真分析,认为帕拉托效率策略而不是纳什效率策略能显著地增加制度网络演化的整体得益水平;复杂制度网络系统小世界网络中的最短路径特点能够增加制度主体间的合作空间,进而增加制度演化的整体得益水平.Institution as a subsystem of social system,is a complexity networks with properties of small-world effect and preferential attachment.Its evolution needs to spend connection costs.This paper brings forward an evolutionary model of institutional network system based on small world network,connection cost,and the node＇s competition capacity,and puts forward Nash efficiency and Pareto efficiency strategy about institutional network evolution.The numerical analysis shows that Pareto efficiency strategy can significantly increase whole profits of institution network evolution other than Nash efficiency strategy.Short-cut path of small world network can promote cooperation among institution nodes and improve whole profits of institution network evolution.
