Abstract

Based on combing domestic and foreign automobile industry policy research and re-lated theories, this article takes the monthly production data of China's passenger car companies from 2016 to 2020 as the research object, and constructs a double differ-ence model to quantitatively evaluate the impact of the double points method on the output of low fuel consumption models and new models. The implementation of the double credit policy will significantly increase the output of low-fuel vehicles, but the impact is lagging behind; At the same time, the implementation of the policy will sig-nificantly increase the output of new energy vehicles in enterprises. Based on this, some suggestions are put forward, such as promoting the efficiency upgrade of new fleet in energy-saving technology and optimizing the policy orientation of new energy credits.
