南南型区域经济一体化带动了城市经济发展吗?

Does South-south Regional Economic Integration Promote Urban Economic Development?

区域经济一体化是实现集聚经济、促进地区协调发展的重要战略手段。本文以沈阳经济区为例,利用系统GMM和差分内差分方法对南南型区域一体化政策的实施效果进行评价。研究结果发现:南南型区域经济一体化政策对沈阳经济区经济增长速度的带动作用不显著,且以往资本投入型的增长驱动模式失效,但一体化政策通过改善区内贸易自由度和人力资本对区域经济增长产生了正向影响;同时,一体化政策实施有利于促进经济的集聚发展,为将来区域内核心城市发挥辐射带动作用创造条件。所以,政府应减少对夕阳产业和落后产业的制度性扶持,集中资源提高地区整体创新能力;在全域范围内统筹规划,进一步降低城市间发展要素的流动壁垒以提高区域核心城市的首位度。

Regional economic integration is an important strategy to realize economic agglomeration and promote regional coordination.Taking Shenyang economic zone as an example,this paper uses systematic GMM and difference-in-difference method to evaluate the implementation effect of south-south regional integration policy.The results show that the south-south regional economic integration policy has no significant driving effect on the economic growth rate of Shenyang economic zone,and the previous growth pattern of capital-input is invalid.However,the integration policy has a positive influence on regional economy by improving the freedom degree of trade and the level of human capital.At the same time,the implementation of the integration policy is conducive to promoting the agglomeration development of the economy and creating conditions for the core cities in the region to play a leading role.Therefore,the government could reduce the institutional support to sunset industries and backward industries,and focus on improving the overall innovation capacity of the region.In order to improve the primacy ratio of regional core cities,overall planning should be carried out to further reduce the flow barriers of development elements.
