创新人才集聚、产业结构优化与经济高质量发展——基于长三角地区41个城市的实证研究

Agglomeration of Innovative Talents,Optimization of Industrial Structure,and High-quality Economic Development:An Empirical Study Based on 41 Cities in Yangtze River Delta Region

随着我国经济迈向高质量发展阶段,各地区对创新人才的需求不断增强。结合2011—2020年中国长三角地区41个城市的统计数据,采用固定效应分析方法,探究创新人才集聚、产业结构优化对长三角地区经济高质量发展的影响。研究发现,创新人才集聚与产业结构高级化融合对经济高质量发展的促进效应更强。通过异质性分析发现,创新人才集聚能显著推动江苏省、安徽省及大城市经济的高质量发展,但对浙江省和中小城市经济的推动作用不显著;产业结构优化及其与创新人才集聚的融合对江苏省经济的促进效应优于浙江省和安徽省,对大城市经济的推动作用大于中小城市。基于门槛效应模型的研究发现,创新人才集聚对经济高质量发展的促进作用随着产业结构优化水平的提高而逐渐增强。为更好地实现区域经济高质量发展的目标,各城市有必要提高创新人才与产业结构的适配性,通过完善人才引进制度和产业体系,提高浙江省和安徽省的人才储备质量和产业水平,从而推动长三角一体化高质量发展。

As China's economy moves towards a stage of high-quality development,the demand for innovative talents in various regions is constantly strengthening.Based on the statistical data of 41 cities in the Yangtze River Delta region from 2011 to 2020,a fixed-effect analysis method is adopted.The results show that the synergistic effect of the agglomeration of innovative talents and the upgrading of industrial structure has a stronger promoting effect on high-quality economic development.The heterogeneity analysis demonstrates that the agglomeration of innovative talents can significantly promote the high-quality economic development of Jiangsu,Anhui and big cities but that it has no significant effect on Zhejiang and small cities.The promoting effect of industrial structure optimization on Jiangsu is greater than that on Zhejiang and Anhui,while the promoting effect on big cities is greater than that on small cities.Using the threshold model,it is found that the promoting effect of innovative talent agglomeration on high-quality economic development is gradually enhanced with the improvement of industrial structure optimization level.In order to better achieve the goal of high-quality development of regional economy,cities must improve the suitability of innovative talents and industrial structure.By improving the talent introduction system and industrial system,the talent reserve and industrial level of Zhejiang and Anhui will be improved,thus promoting the integrated high-quality development of the Yangtze River Delta.
