Abstract:    In the context of central-local decentralized governance, effective synergy of industrial policies across government levels is critical for fostering technological innovation in emerging sectors. Using the data from 9,492 listed companies in China, this study employed the fixed-effect and mediation effect models to explore the impact of central-local industrial policy synergy on new energy technology innovation and its underlying mechanisms. The key findings are as follows: (1) Central-local industrial policy synergy exerts a positive impact on corporate new energy technology innovation, with the effect of actual support synergy being significantly stronger than that of attitude encouragement synergy. (2) The mechanism tests indicated that central-local industrial policy synergy, primarily under actual support synergy, enhances corporate new energy technology innovation through three pathways: R&D investment, R&D subsidies, and tax environment optimization. (3) The Heterogeneity analysis showed that central-local industrial policies have a more pronounced effect on promoting new energy technology innovation in non-state-owned and small enterprises. This study has expanded and enriched the research on the synergistic effects of central-local industrial policies in the field of emerging technology innovation, and it will provide valuable insights for optimizing policy coordination to drive enterprise innovation in emerging technologies.

Key words: central-local industrial policy synergy, new energy technology innovation, actual support synergy, attitude encouragement synergy
