摘　　要：本文以知识产权示范城市的设立为准自然实验,使用2010—2019年中国273个地级市的数据,采用逐期双重差分法考察了知识产权示范城市的设立对城市吸引境外直接投资的影响效应。研究发现,知识产权示范城市的设立可以显著增加城市境外直接投资的流入量,这一结论在经过一系列稳健性检验后依然成立。机制分析表明,知识产权示范城市的设立可以通过增加知识产权制度供给和优化创新要素配置来增强城市的区位优势,进而吸引更多的境外直接投资;但同时也通过增加境外技术授权来挤出部分境外直接投资。异质性分析显示,知识产权示范城市的设立对东部地区、行政级别高以及市场化程度高的城市境外直接投资的促进作用更明显。最后,本文分析了知识产权示范城市的空间效应,发现知识产权示范城市对于境外直接投资吸引量不是来源于存量资源的空间再配置效应,而是来自于净增长效应。本研究对我国进一步实施知识产权战略,优化城市国际化营商环境,推动外资平稳发展具有重要的启示意义。Based on panel data with 273 cities from 2010 to 2019,this paper uses difference-in-differences method to investigate the effect of the establishment of intellectual property demonstration cities on the inflow of foreign direct investment( FDI).Benchmark regression shows that the establishment significantly increases FDI inflows,which remains stable after several robustness tests.Mechanism analysis shows that the improvement is achieved by increasing the supply of intellectual property systems and optimizing the allocation of innovation factors.However,the establishment of intellectual property demonstration cities “squeezes out”FDI through an increase in overseas technological authorization.Heterogeneity analysis finds that cities in the eastern China,and those with higher administrative levels,or those with higher levels of marketization benefit more from the establishment of intellectual property demonstration cities.Our in-depth investigation reveals that the FDI attraction of these cities is not the spatial reallocation effect of stock resources but,rather,the net growth effect.This research points to significant implications for the government in terms of further implementing an intellectual property strategy,optimizing the international business environment,and promoting the steady development of foreign investment.
