Electric vehicle is an important tool for clean replacement in the field of transportation in China, and its high-quality development is crucial to the low- carbon development in the field of transportation. The development of electric vehicles is an overall, systematic and long-term work, involving the government,enterprises, users and other multiple subjects, including policy, research and development, production, operation, recycling and other links. The evaluation system of electric vehicle development situation needs to consider relevant factors as a whole, accurately position the development trend of electric vehicles in the city, and provide support for the city to formulate electric vehicle development policies. The policy chain, technology chain and industry chain in the development of electric vehicles are considered, and the evaluation index system of the development trend of electric vehicles from the five dimensions of policy support, technology development, market scale, supporting construction and business ecology is put forward. Combined with quantitative analysis and expert scoring method, the evaluation methods of each index system are given, and the evaluation method of the development trend of electric vehicles based on analytic hierarchy process. Finally, taking Jiangsu Province as an example, the values of various indicators of the development status of electric vehicles in Jiangsu Province are given, and compared with the relevant evaluation of Shanghai, the development suggestions of electric vehicles in Jiangsu Province are given.
