National macro-industrial policy is an important means to guide, guarantee and promote the healthy development of new energy automobile industry. CiteSpace is used to draw a knowledge map to analyze relevant literature on new energy automobile industry policies and policy coordination, and clarify the logical framework and evolutionary mechanism of policy research. Keywords collinear knowledge graph and cluster analysis results show that the deviations in the process of policy evolution shift the research perspective to policy effect evaluation and policy coordination trend analysis. Policy coordination, collaborative innovation, industrial chain innovation and innovation network have become new clusters of high-frequency words. In addition, the cluster "central-local policy coordination" reflects that policy subject coordination is the most important aspect of policy coordination in different dimensions, which is also the key to further refine policy research.
