Policy Evolution and Intensity Evaluation of the Chinese New Energy Vehicle Industry Policy: The Angle of the Dual-Credit Policy

The dual-credit policy advances the process of vehicle electrification; however, few studies have reviewed the policy preferences and development trends of the Chinese new energy vehicle industrial policy at different stages from the development angle of the dual-credit policy. This article reviews the policy evolution of the Chinese new energy vehicle industrial policy based on the 2T model (time and types) and evaluates the policy intensity of different industrial policies by PI index. The results find that the Chinese new energy vehicle industry policy is divided into three development periods: 2004–2008—promotion policy and technological policy; 2009–2013—financial policy; and 2014–2020—charging infrastructure policy. The early policy preference for new energy vehicles was not found to be significant. Financial policies have significantly stimulated the development of the new energy vehicle industry, and the implementation of the charging infrastructure policy is late. The policy intensity of the promotion policy is the strongest, followed by the technological policy, and the policy intensity of the charging infrastructure is the weakest. The policy intensity of the financial policy will weaken in the later period. The promulgation of the dual-credit policy reflects the continuity and synergy of policy development.
