Abstract: Proceeding from a game model of network，this paper regards all the thirtyone provincial governments as a network decided by geographical factors and it also studies the behaviors of local governments and environmental pollution treatmentWe find that there is a strong peer effect of neighborhood in the respect of environmental pollution treatment and strategically complementary behaviors among local governmentsTherefore，the policy suggestion of this paper is that as the policymaker，central government should recognize the key province from the network of provincial local governments and guarantee the leading role of key province in promoting the investment level of its neighboring provinces
