政府主导型区域经济一体化对周边城市发展的影响差异分析——基于工业水平视角的PSM-DID实证研究

Analysis on the Difference of the Impact of Government-Led Regional Economic Integration on the Development of Surrounding Cities:An Empirical Study of PSM-DID from the Perspective of Industrial Difference

以政府主导型区域经济一体化对周边城市经济增长的影响及机制作为研究内容,采用2000—2016年中国277个城市面板数据,运用双重差分倾向得分匹配法(PSM-DID)进行实证检验。研究发现:①政府主导型区域经济一体化能够促进周边城市的经济增长,对工业水平中等的周边城市的经济增长效果最大,工业水平较高的周边城市效果次之,工业水平较低的周边城市效果最低。②政府主导型区域经济一体化促使周边城市政府增加财政投入和提高第二产业就业比来增强其城市竞争力。③政府主导型区域经济一体化对于不同工业水平周边城市的全社会固定资本投资和劳动力流动的作用具有异质性。

Taking the influence and mechanism of government-led regional integration on the economic growth of surrounding cities as the research content,using the panel data of 277 cities in China from 2000 to 2016,the double differential tendency score matching method(PSM-DID)was used for empirical testing.This paper finds that:1)The government-led regional integration can promote the economic growth of the surrounding cities,and the economic growth effect is the highest for the surrounding cities with moderate industrial levels,followed by the surrounding cities with higher industrial levels,and the surrounding cities with lower industrial levels.The city has the lowest effect.2)The government-led regional integration prompts the surrounding city governments to increase financial investment and increase the employment ratio of the secondary industry to enhance their urban competitiveness.3)The government-led regional integration has heterogeneity in the role of fixed capital investment and labor mobility in the surrounding cities of different industrial levels.
