中国制造业“三链融合”发展的区域差异及空间效应研究

Research on Regional Differences and Spatial Effects of "Three-chain Integration" Development in China's Manufacturing Industry

构建制造业“三链融合”综合评价体系,以改进的耦合协调度模型、Dagum基尼系数和空间计量模型,分析中国制造业“三链融合”发展的时序演变、区域差异及空间效应。结果表明:在时间维度上,中国制造业“三链融合”整体发展水平呈不断上升趋势,处于勉强协调阶段,广东、江苏等位于领先位置;在区域差异上,总体基尼系数呈“V”型演变趋势,区域间差异是制造业“三链融合”发展差异的主要来源,且东部-西部的区域间差异最大;在空间维度上,中国制造业“三链融合”发展存在显著空间集聚特征和空间溢出效应。因此,应完善体制机制建设,激发企业创新活力,提高“三链融合”溢出效应,以推动区域协调发展。

Constructing a comprehensive evaluation system for the"three-chain integration"of China's manufacturing industry,using an improved coupling coordination model,Dagum Gini coefficient and spatial econometric model,this paper analyzes the temporal evolution,regional differences,and spatial effects of the"three-chain integration"development in China's manufacturing industry.The results show that in terms of time dimension,the overall development level of"three-chain integration"of China's manufacturing industry is continuously increasing,and it is in a barely coordinated stage,with Guangdong and Jiangsu leading the way.In terms of regional differences,the overall Gini coefficient shows a"V"-shaped evolution trend,and the regional difference is the main source of the development difference of"three-chain integration"in the manufacturing industry,and the regional difference between the east and west is the largest.In terms of spatial dimension,there are significant spatial agglomeration characteristics and spillover effects in the"three-chain integration"development of China's manufacturing industry.Therefore,it is necessary to improve the construction of institutional mechanisms,stimulate the innovation vitality of enterprises,enhance the spillover effect of"three-chain integration",so as to promote regional coordinated development.
