江苏省先进制造业集聚水平及影响因素研究

Study on the Agglomeration Level and Its Influencing Factors of Advanced Manufacturing Industry in Jiangsu

先进制造业是制造业高质量发展的标志,发展先进制造业有利于培育江苏省在产业中的竞争力。采用区位熵和修正的EG指数对江苏省先进制造业整体及其13个小类产业的集聚程度进行测算,并使用地理探测器对其集聚的影响因子进行探测。结果表明:(1)江苏省先进制造业在区域间的集聚呈现出不均衡发展的态势。(2)13个小类产业的集聚程度也各不相同,其中物联网业、集成电路业和新型显示业是集聚程度最高的小类产业。(3)江苏省先进制造业集聚受多种因子共同驱动影响,随着产业的发展,地区政策因素成为最核心的影响因素;且任意两个因子的交互探测的影响力均为非线性增强和双因子增强,地方财政支出与专业技术人员数量的交互影响力水平最高。

Advanced manufacturing industry is the symbol of high-quality development of manufacturing industry,developing advanced manufacturing industry is conducive to cultivating the industrial competitiveness of Jiangsu Province.This paper applies location quotation and modified EG index to measure the agglomeration degree of advanced manufacturing industry and its 13 sub-industries in Jiangsu,and Geodetector is used to explore the influencing factors of advanced manufacturing industry agglomeration in Jiangsu.The results are as follows:(1) The agglomeration of advanced manufacturing industry in Jiangsu shows a trend of unbalanced development among regions.(2) The agglomeration degree of 13 sub-industries also varies,among which,the internet of things,integrated circuits and new-type display industry are the most assembled industries.(3) The agglomeration of advanced manufacturing industry in Jiangsu Province is influenced by various factors.With the development of industry,the regional policy factor has become the core factor,meanwhile,the influence of any two factors after interaction shows nonlinear enhancement and bi-factor enhancement.The highest interactive impact is between local financial expenditure and number of professional technicians.
