新型城镇化对产业结构升级的影响研究——以36个中小城市为例

Research on the Impact of New Urbanization on the Upgrading of Industrial Structure——In case of 36 small and medium-sized cities

中小城市的可持续发展和产业结构升级,是现阶段城市健康持续发展和城市群质量提升的关键所在。本文在对产业结构影响因素分析的基础上,引入恩格尔系数和城乡收入差距变量,采用2005-2017年36个中小城市的数据,研究新型城镇化对产业结构升级的影响,运用固定面板模型和面板校正标准误对理论进行实证分析,结果表明,城镇化率、人力资本、研发投入、建成区绿化覆盖率以及政府干预水平,能显著促进中小城市产业结构升级。对外开放度、投资率、城乡收入差距以及恩格尔系数明显阻碍了产业结构升级。

The sustainable development and upgrading of industrial structure of small and medium -sized cities, which are the keys to healthy and sustainable development of cities and urban mass improvement. Based on the analysis of factors which affect the industrial structure, this paper introduces the Engel coefficient and the urban-rural income gap variable, and uses the data of 36 small and medium-sized cities from 2005 to 2017 to study the impact of new urbanization on industrial structure upgrading. Empirical analysis of the theory uses fixed panel model and panel correction standard. The results show that urbanization rate, human capital, R&D investment, green coverage in built-up areas and government intervention level can significantly promote the upgrading of industrial structure in small and medium-sized cities;openness, investment rate, urban-rural income gap and Engel coefficient have obviously hindered the upgrading of industrial structure.
