The Effect of Place-Based Policy on Urban Land Green Use Efficiency: Evidence from the Pilot Free-Trade Zone Establishment in China

The improvement of urban land green use efficiency is significant in promoting sustainable development. As an important place-based policy China, the pilot free-trade zone establishment has exerted a profound impact on economy and society. Meanwhile, issue whether can improve or not missing from prior literature, which concern this study. Specifically, based super-efficiency slacks-based measure model, we first 279 cities China 2011 to 2019 then multi-period difference-in-differences method investigate causal effect efficiency. results show that significantly improved efficiency, especially eastern cities, coastal with high economic development level. Further, there exists spatial spillover This study implications for optimal allocation deployment policies, serving structural upgrading carbon neutrality vision.
