Abstract

This paper examines 333 Chinese cities (2009-2023) using the comprehensive innovation reform pilot zones as a quasi-natural experiment and difference-in-differences method to study institutional innovation’s impact on urban green total factor productivity (GTFP). Results show the pilot zone policies significantly improve urban GTFP, with robustness confirmed by city/year fixed effects and control variables. Parallel trend tests indicate no pre-policy differences between treatment and control groups, with effects manifesting post-implementation. Further robustness tests (replacing explained variables, removing specific cities) validate core conclusions. Mechanism analysis reveals the policy works through industrial structure upgrading and advancement, enhancing resource allocation efficiency and environmental performance. This research demonstrates pilot zones’ dual significance in promoting innovation-driven development and urban green transformation for high-quality growth.
