成渝地区双城经济圈经济高质量发展对科技人才集聚的影响效应研究

Study on the effect of high-quality economic development of Chengdu-Chongqing dual-city economic circle on the agglomeration of scientific and technological talents

成渝地区双城经济圈经济高质量发展对支撑全国经济高质量发展起到助推器作用,科技人才集聚规模对城市圈经济高质量发展的影响日益显著。基于成渝地区双城经济圈2011—2020年的面板数据,采用熵权法测算出经济高质量发展综合指数,运用莫兰指数探索成渝地区双城经济圈内科技人才集聚是否存在空间关联性,运用空间杜宾固定模型(SDM)检验科技人才集聚规模在成渝地区双城经济圈内是否会产生空间溢出效应。研究发现:(1)结合经济距离权重分析,成渝地区双城经济圈内各地区的科技人才集聚存在着显著的空间相关性;(2)成渝地区双城经济圈经济高质量发展水平提升对本地区科技人才集聚具有较强的促进作用,经济高质量发展水平越高,对本地区科技人才集聚的促进作用越大,同时,邻近地区经济高质量发展水平也会对本地区科技人才集聚产生一定的促进作用;(3)科技人才集聚水平除了受经济高质量发展水平的影响外,受政府干预的影响也较大。建议通过逐步缩小区域间经济高质量发展差距、建立健全人才引进政策、构建有效市场和有为政府相互补充的市场环境、建立科技人才集聚空间关联意识等途径来提升成渝地区双城经济圈内各地区经济高质量发展水平。

Since the reform and opening up,China’s economy has undergone a transformation from pursuing rapid economic development to pursuing high-quality economic development.In terms of regional economic construction,efforts should be made to create the largest scale agglomeration effect through the construction of urban agglomerations,and to promote the development of surrounding small and medium-sized cities while comprehensively improving the economic and social benefits of urban agglomerations.For example,the important economic growth pole in the western region is the Chengdu-Chongqing economic circle,and the“dual core”of“Chongqing-Chengdu”drives the development of the surrounding cities.Economic development is inseparable from the support of talents,and scientific and technological talents are the key factors to realize the innovation-driven development strategy.To achieve high-quality economic development,this paper proposes to do a good job in the reserve of scientific and technological talents.The reserve or agglomeration degree of scientific and technological talents in the region has an important relationship with the quality of regional economic development.In order to better serve the high-quality development and construction of regional economy,it is necessary to study the factors affecting the agglomeration of scientific and technological talents,especially the impact of the high-quality development level of regional economy on this agglomeration.In order to explore the impact of high-quality economic development level on the agglomeration of scientific and technological talents,this paper first clarifies the dimensions of high-quality economic development in the Chengdu-Chongqing economic circle by constructing an evaluation system of high-quality economic development indicators,and uses the entropy weight method to measure the comprehensive high-quality development index.At the same time,in order to measure the agglomeration of scientific and technological talents in the Chengdu-Chongqing economic circle,the index of location entropy of scientific and technological talents is introduced.Secondly,based on the data of high-quality economic development and agglomeration of scientific and technological talents in the Chengdu-Chongqing economic circle from 2011 to 2020,the current situation of the research object is analyzed.Then,on the basis of the previous basis,a basic regression model is used to explore the impact of high-quality economic development on the agglomeration of scientific and technological talents in Chengdu-Chongqing region.After that,after drawing preliminary conclusions,the spatial Dubin model is used to further explore whether the addition of spatial factors will affect the research conclusions.Furthermore,the partial differential method of the spatial Dubin modelis used to explore the size of spatial spillover effect.Finally,in order to ensure the scientificity of the empirical model and the rationality of the empirical results,a robustness test is conducted.The study finds that:(1)The distribution of scientific and technological talents in the dual-city economic circle of Chengdu-Chongqing region is not coordinated,but is concentrated in a significant spatial correlation.(2)The high-quality economic development level of Chengdu-Chongqing economic circle has a strong promoting effect on the agglomeration of scientific and technological talents in the region,and the spatial spillover effect of the high-quality economic development level is relatively large.(3)In addition to the impact of high-quality economic development,the level of scientific and technological talent agglomeration is also greatly affected by government intervention.According to these research conclusions,the following main suggestions are put forward:(1)Improve the level of scientific and technological talent agglomeration,and give full play to the effect of the agglomeration.(2)Talent introduction policies should be established,and the quality of scientific and technological talent agglomeration should be improved.(3)Agood market environment is supposed to bebuilt,where effective markets and promising governments are mutually complementary.
