摘要
国家中心城市作为我国城镇体系的塔尖,承担着辐射带动区域经济增长的责任。选取2004—2019年中国103个地级市作为研究对象,基于多期双重差分模型实证检验了国家中心城市建设这一政策对区域经济增长的影响,并对其异质性和作用机制进行了进一步探讨。结果表明:对于设有国家中心城市的区域来说,区域内城市的年均经济增长率显著提高了约0.87个百分点,且国家中心城市的带动效应具有可持续性,在设立后第8年,带动效应依旧显著,但这一政策效果的发挥存在着时间滞后性,在其设立后第4年,其带动效用才开始显著;机制检验表明,国家中心城市的建设可以通过促进与周边城市的分工协作,从而提高整个城市群的空间功能分工水平来促进区域经济的增长。
As the spire of nationwide urban system,the national central cities take the responsibility to stimulate regional economic growth.Taking the sample data of 103 prefecture-level cities in China from 2004 to 2019,and using the Multi-phase Difference-in-Differences model,this paper investigated the impact of the policy of construction of national central cities on the regional economic growth,and made further discussion on its heterogeneity and the mechanism of action.The results showed that for those areas with national central cities,its average annual economic growth rate have increased significantly by about 0.87 percentage point;and the driving effect of national central cities are sustainable.Meanwhile,in the eighth year after the establishment of the national central cities,the driving effect is still significant,but there is a time lag in the exertion of the policy effect,in the fourth year after the establishment,the driving effect began to be significant;the mechanism also showed that the construction of national central cities can promote the division and cooperation with the peripheral cities,and improve the overall level of the division of labor in the function of the space of the urban agglomeration to promote regional economic growth.
