"反向创新飞地"对城市创新效率的影响研究OACHSSCD

At present,the construction of"Reverse Innovation Enclaves"has become an important starting point to pro-mote regional coordinated development.This paper systematically collects the information of"Reverse Innovation Enclaves"across the country,constructs relevant databases,and combines the panel data of 283 prefecture-level cities in China from 2010 to 2023 to empirically analyze the impact of"Reverse Innovation Enclaves"construction on urban innovation efficiency by using multi-time point difference-in-difference method.The study finds that the"Reverse Innovation Enclaves"significantly improves the innova-tion efficiency of the cities(especially large cities)in the central region,and has no significant impact on the eastern and western cities.The"Reverse Innovation Enclave"has a significant promoting effect on the innovation efficiency of the inflow cities in the enclave,which is particularly prominent in the developed eastern and central regions,but the effect has obvious scale threshold,mainly concentrated in the mega cities in the enclave.This paper can provide an empirical reference for the regions to carry out the construction of"Reverse Innovation Enclaves",which is of great significance to break the barriers of regional development and rea-lize the coordinated development of the region.
