Abstract: In recent years, the new energy automobile industry has become a nationl strategy, and local cities have also taken the lead in deploying the new energy automobile industry, and industry competition among cities has intensified. This article takes Chengdu’s new energy automobile industry as the research object, uses Porter’s “diamond” model theory and the characteristics of the new energy automobile industry to construct a “new diamond model” to determine the competitiveness evaluation index of the new energy automobile industry, and then adopts the combina tion evaluation method of gray correlation degree and ideal solution calculates the relative closeness of each evaluation index between Chengdu and the benchmark cities (Shanghai, Beijing, Wuhan, Chongqing), and compares and analyzes the gap between Chengdu and the benchmark cities. For the benchmark gap, this article puts forward relevant suggestions on improving the construction of charging infrastructure, increasing the promotion of new energy vehicles, improving technological innovation capabilities, and improving the parts and components industry supporting policies and industrial support policies.
