Evaluating the effect of China pilot Free Trade Zone (FTZ) policy on green technology innovation is important for achieving China's carbon neutrality targets. Based on the panel data of 30 provincial administrative regions in China from 2009 to 2019, this study investigates the effect of the pilot FTZ policy on green technology innovation by using the difference-in-differences method. The study's findings indicate the following: (1) The pilot FTZ policy promotes the development of green technology innovation, and there is a policy lag in a few pilot regions. (2) The mediation effect analysis shows that the pilot FTZ policy promotes the development of green technology innovation by improving the marketization process and enhancing innovative talent gathering. (3) The heterogeneity analysis shows that the pilot FTZ policy is more effective in promoting green technology innovation when implemented in regions with developed economies or higher levels of human capital. Moreover, the pilot FTZ policy mainly has a significant promoting effect on green utility model patents. Based on these results, policy recommendations are proposed to promote the development of green technology innovation and the achievement of China's carbon neutrality targets.
评估中国自由贸易试验区（FTZ）试点政策对绿色技术创新的影响，对于实现中国的碳中和目标具有重要意义。基于2009年至2019年中国30个省级行政区的面板数据，本研究采用双重差分法考察了自由贸易试验区试点政策对绿色技术创新的影响。研究结果表明：（1）自由贸易试验区试点政策促进了绿色技术创新的发展，少数试点地区存在政策滞后现象。（2）中介效应分析表明，自由贸易试验区试点政策通过推进市场化进程和加强创新人才集聚来促进绿色技术创新的发展。（3）异质性分析表明，自由贸易试验区试点政策在经济发达或人力资本水平较高的地区实施时，对促进绿色技术创新更有效。此外，自由贸易试验区试点政策主要对绿色实用新型专利有显著的促进作用。基于这些结果，提出了促进绿色技术创新发展和实现中国碳中和目标的政策建议。
