先进制造业产业链现代化水平空间差异及空间关联研究

Research on Spatial Difference and Spatial Correlationof Advanced Manufacturing Industry Chain Modernization Level

依据2012—2021年中国先进制造业省际面板数据,运用熵权-Topsis法测度先进制造业产业链现代化水平,结合标准差椭圆法、Kernel密度估计法、基尼系数法、社会网络分析法考量先进制造业产业链现代化水平的空间差异及空间关联特征。结果显示:先进制造业产业链现代化水平时间上整体呈上升趋势,空间上具有“东高西低”的五级梯度分布特征;先进制造业产业链现代化水平重心整体向西南方向转移,区域存在极化和拖尾现象;先进制造业产业链现代化水平整体网络向稠密化发展,越来越多的省份由边缘区向半边缘区和中心区转变。鉴于此,应增加先进制造业资源要素投入、加速技术突破和成果转化、促进关键技术自主可控、发挥核心省市辐射带动作用以推动区域经济协调发展。

Based on the inter-provincial panel data of China’s advanced manufacturing industry from 2012 to 2021,the entropy weighted Topsis method was used to measure the modernization level of the industrial chain of advanced manufacturing industry,and the spatial differences and spatial correlation characteristics of the modernization level of the industrial chain of China’s advanced manufacturing industry were explored by combining standard deviation ellipse method,Kernel density estimation method,Gini coefficient method and social network analysis method.The results show that the modernization level of China’s advanced manufacturing industry chain is on the rise in time and has a five-level gradient distribution of“high in the east and low in the west”in space.The center of gravity of the modernization level of the advanced manufacturing industry chain is shifting to the southwest,and there are polarization and tailing phenomena in the region.The overall network of the modernization level of the advanced manufacturing industry chain is becoming dense,and more and more provinces and cities are transforming from marginal regions to semi-marginal regions and central regions.In view of this,we should increase the input of advanced manufacturing resources,accelerate technological breakthroughs and achievements transformation,promote the autonomy and control of key technologies,and give play to the radiating role of core provinces and cities to promote the coordinated development of regional economy.
