This paper focuses on the empirical study and analysis of this type of problems, in order to put forward the feasible solution of social insurance for migrant workers. The migrant workers generally refer to the labor workers of household registration as farmers working in towns for non-agricultural occupation. At present, China＇ s migrant workers has exceeded 2.6 billion, and this group has been long in the city and rural edge, difficult to get the social insurance policy. According to the National Bureau statistics data, the migrant workers of not buying industrial injury insurance, endowment insurance, medical insurance and unemployment insurance are respectively 67.64%, 73.37%, 73.77% and 84.65%.

Meanwhile, we also observe that the introduction of Moran rule, which needs to consider all neighbor＇s information, can markedly promote the aggregate cooperation level, that is, randomly selecting the neighbor proportional to its payoff to imitate will facilitate the cooperation among agents.
