中国数字产业集聚水平的演变特征与提升策略

Study on the Evolution Characteristics and Improvement Strategies of China’s Digital Industry Agglomeration Level

基于2000—2021年全国31个省(区、市)的新注册企业数据构建测度指标体系,在对数字产业集聚水平进行分析的基础上,采用灰色关联度分析法分析数字产业集聚的影响因素,采用Dagum基尼系数、莫兰指数和Kernel核密度估计方法分析数字产业集聚水平的区域差异性与动态演化特征。研究认为,全国数字产业集聚水平不断下降,地区差距明显扩大,呈现出从东部地区向西部地区递减的趋势。数字产业集聚水平主要受地区规模、市场化程度、区位条件、数字基础设施建设水平与科技人力投入的影响,研发与技术导向尤为明显。数字产业集聚水平的空间非均衡性突出,区域间差距是主要来源。东北地区和西部地区数字产业集聚水平偏低,科技人力投入不足是重要的制约因素。中国应在实施差异化发展战略、引进和培养人才、统筹调配资源等方面采取措施,从而优化数字产业空间布局和推动区域数字经济协调发展。

Based on the data of newly registered enterprises in 31 provinces of China from 2000 to 2021,the measurement index is constructed to analyze the level of digital industry agglomeration.Then,grey relational analysis is used to analyze the influencing factors of digital industry agglomeration,and Dagum Gini coefficient,Moran index and Kernel density estimation methods are used to analyze the regional differences and dynamic evolution characteristics of digital industry agglomeration.The study found that the level of digital industry agglomeration in China has been declining,and the regional gap has expanded significantly,showing a decreasing trend from the eastern region to the western region.The agglomeration level of digital industry is mainly affected by regional scale,marketization degree,location conditions,digital infrastructure construction level and scientific and technological manpower input.The impact of R&D and technology is becoming more and more obvious.The spatial disequilibrium of the agglomeration level of digital industry is prominent,and the inter-regional gap is the main source.The agglomeration level of digital industry in the northeast and western regions is low and the insufficient investment of science and technology manpower are important limiting factors.Therefore,China should optimize the spatial layout of digital industry and promote the coordinated development of regional digital economy by implementing differentiated development strategies,introducing and training talents,and coordinating and deploying resources.
