Abstract: This paper collects, combs and screens a total of 139 policies issued from 2007 to June 30th，2017 at the national level on new energy vehicles. The scoring criteria were designed from the two dimensions of policy strength and policy measures. A quantitative model was established on the coordination degree of policies and the coordination and evolution of new energy vehicle policy and related departments were analyzed. The results show that the management of the new energy vehicle industry has formed a diversified mode with the State Council as the top decision-maker and the ministries and commissions participating according to their functions, and has gradually evolved from relying on a single measure to the comprehensive utilization of various measures. The development of the new energy vehicle industry has also changed from the policy-driven mode to the policy-and market-driven mode. There are also problems to be solved. For example, the coordination degree of policy measures is imbalanced, core departments are too concentrated and forms of departmental coordination need to be improved. Based on the research results，the following policy recommendations are proposed：（1）reasonably match the strength and content of policy measures, and stimulate system synergy；（2）intensify the coordination of financial, technical and regulatory measures with other measures to tackle the shortcomings.
