数字经济空间关联及其与实体经济发展的交互影响

Research on the Spatial Correlation of Digital Economy and the Interactive Influence with the Development of Real Economy

把握数字经济空间关联与实体经济发展交互关系,有助于把握产业变革机遇,推动数字经济与实体经济融合以及区域协调发展。基于2011—2020年我国30个省份(未含港澳台藏地区)的面板数据,分析测算各省份数字经济发展水平,进而结合修正的引力模型、社会网络分析和空间计量方法分析数字经济空间关联网络结构和演化特征,探究其与实体经济发展的交互作用。研究发现,我国数字经济发展快速,但空间上存在明显的不平衡性,呈现由东部地区向中部地区再向西部地区扩散的演化趋势;数字经济空间关联网络日趋复杂,逐渐形成以京津冀鲁、长三角、珠三角和成渝地区为中心的极核式扩散区域空间结构形态,具有明显的东密西疏特征;数字经济空间关联网络密度呈上升态势,网络效率呈下降态势,数字经济空间流动性不断提升,网络结构稳定性不断增强,表现出溢出效应的省份主要分布在京津冀鲁、长三角、珠三角地区,表现出受益效应的省份主要分布在东北、西北以及华中等地区;数字经济空间关联强度提高有助于实体经济发展,邻近省份数字经济空间关联强度提高对本省份数字经济空间关联具有促进作用;数字经济空间关联与三次产业发展的交互作用存在差异,相比于第一、第三产业,邻近省份第二产业发展与数字经济空间关联的交互作用最为突出。因此,应建立区域协同机制,提高数字经济空间关联网络密度,以全局视角推动数字化;重视数字经济区域发展平衡性,发挥重点区域示范引领作用,辐射带动周边地区数字化发展;中西部地区借助自身区位或资源优势,因地制宜差异化发展数字经济,促进数字资源跨区域流动;积极推动数字经济与第一、第二、第三产业融合发展。

Understanding the spatial correlation of digital economy and the interactive influence with the development of real economy can help us to take advantage of the opportunity of industrial change and promote the integration and coordinated development of digital economy and real economy.Based on China's provincial panel data from 2011 to 2020,the authors measure the development level of of digital economy in 30 provinces(excluding Hong Kong,Macao,Taiwan and Tibet);and with the help of the modified gravity model,social network analysis and spatial metrology methods,the authors analyze the structure and evolution pattern of the spatial correlation network of the digital economy,and explore its spatial interaction with the development of the real economy.It is found that:though the digital economy has been developed quickly in China,there is spatial imbalance in that,and the development trend shows the evolution pattern of spreading from the eastern region to the central region and then to the western region;the spatial correlation pattern is getting more and more complicated,and the inter-provincial digital economy spatial correlation gradually shows a complex network pattern of polar core diffusion centered on the Beijing-Tianjin-Hebei region,Yangtze River Delta,Pearl River Delta,and Chengdu-Chongqing economic zone,with the characteristic of high density in eastern regions and low in western regions;the density of inter-provincial spatial correlation of digital economy is increasing,the network efficiency of that is decreasing,the spatial mobility of that is increasing,the stability of the network structure is improving,provinces with spillover effect are located in the Beijing-Tianjin-Hebei,Yangtze River Delta and Pearl River Delta regions,and provinces received the beneficial effects are located in the north-eastern,north-western,and central regions;the increase in the intensity of digital economy spatial correlation in certain province can significantly promote the development of the real economy of this province,and the increase in the intensity of digital spatial correlation of the neighboring surrounding provinces plays a significant role in promoting the spatial correlation of this province's digital economy;and there is a difference in the interactive industrial development,comparing to the primary and tertiary industry,the interactive influence of spatial correlation of digital economy on the second industry is the most significant.So,we should,first,formulate the regional coordinated mechanism,increase the density of spacial correlation network of digital economy,and promote the digitization in an all-round way;second,we should pay more attention to the balanced development of digital economy in different regions,and give full play to the leading role of key regions to lead the digital development of surrounding regions;third,we should promote the development of central and western regions by taking advantages of the local resources and the differential development of digital development according to the different condition of different regions,and promote the inter-regional flow of digital resources;and fourth,we should promote the integrated development of digital economy and the primary,secondary and tertiary industries.
