依托区域联动促进长三角对接国际大循环:FDI流入视角

Promoting the Yangtze River Delta to Connect with the International Cycle by Relying on Regional Linkage:from the Perspective of FDI Inflow

“构建双循环新发展格局”和“长三角区域一体化发展”均已上升为国家战略,长三角地区应紧扣高质量发展,加强两者之间的有机联系和战略对接,为我国新一轮的改革开放提供有力支持。在此背景下,文章基于1995—2018年我国长三角地区30个地级以上城市的面板数据,将长三角城市经济协调会视为一项政策实验,运用双重差分法从FDI流入的视角评估协调会的成立和扩容对参与国际大循环的影响。结果表明:城市群扩容的一体化政策显著提高了整体城市、原位城市、新进城市的FDI强度,且对新进城市所产生的政策效应远远大于原位城市,一体化战略对地区参与国际大循环具有显著的促进作用,并在此基础上提出相关建议。

“Building a double-cycle new development pattern”and“Yangtze River Delta regional integrated development”have both been promoted as national strategies.The Yangtze River Delta region should closely follow the high-quality development,strengthen the organic connection and strategic docking between the two,and provide strong support for the new round of reform and opening up in China.In this context,based on the panel data of 30 prefecture-level and above cities in the Yangtze River Delta region of China from 1995 to 2018,this paper considers the Yangtze River Delta Economic Coordination Committee as a policy experiment,and uses the differential difference method to evaluate the impact of the establishment and expansion of the coordination Committee on the participation in the international grand cycle from the perspective of FDI inflow.The results show that the integrated policy of urban agglomeration expansion has significantly increased the FDI intensity of the overall city,the original city,and the new city,and the policy effect on the new city is far greater than the original city.The integration strategy has a significant role in promoting regional participation in the international cycle,and relevant suggestions are made on this basis.
