This paper,based on the perspective of policy synergy,took 30 provinces(autonomous regions and municipalities)of China from 2007 to 2020 as research objects to construct an evaluation index system for high-quality economic development.The entropy method was used to measure the level of high-quality regional economic development,and the double fixed effects model was employed for empirical analysis in order to explore the impact of climate policy on the high-quality regional economic development.The results showed that:climate policy synergy had a U-shaped impact on high-quality regional economic development,indicating initial suppression followed by promotion;when the level of climate policy synergy exceeded 7.9,the promotion effect on high-quality regional economic development began to be highlighted;when the impact of the climate policy synergy on the high-quality economic development of the central and western regions followed a U-shaped pattern,the effect on the eastern region was not significant;in the post-Paris era,the climate policy synergy had an increasingly significant influence on the high-quality regional economic development.Therefore,it was necessary to strengthen the top-level design of climate policies to achieve top-down vertical synergy;political advantages and institutional foundations need to be utilized to enhance horizontal synergy among policy subjects;cross-regional and cross-sectoral coordination mechanisms should be established to achieve full flow of information and resources and achieve a"win-win"situation for addressing climate change and promoting the high-quality regional economic development.
