中国数字经济产出的空间关联网络结构与影响因素研究

A study on the spatial network structure and influencing factors of China''s digital economic output

摘要:

基于2007—2017年中国区域投入产出数据，使用修正的引力模型测算与识别中国数字经济产出的空间关联，并运用社会网络分析方法（SNA）及二次指派程序（QAP）对中国数字经济增长的空间特征及影响因素进行实证分析。研究发现：样本期内，中国数字经济产出空间关联整体网络“中心—外围”结构稳定，并呈现出密度提升、关联程度提高的趋势。根据不同省市在关联网络中的位置，可将整体网络划分为双向溢出、净溢出、净收益与经济人四大板块。数字经济产出空间关联受消费水平、产业结构、数字基础设施、数字治理水平、开放水平、移动端数字设备相对差异等因素的影响。

Abstract:

Based on China"s regional input-output data from 2007 to 2017, this paper uses the modified gravity model to measure and identify the spatial correlation of China"s digital economic output, and uses social network analysis (SNA) and quadratic assignment procedure (QAP) to make an empirical analysis on the spatial characteristics and influencing factors of China"s digital economic growth. The results show that: in the sample period, the overall network structure of China"s digital economic output spatial correlation is stable, the density and correlation degree are improved, and the "center periphery" structure is significant. According to the location of different provinces and cities in the network, the network is divided into four parts: two-way spillover, net spillover, net income and economic man. The output spatial correlation of digital economy is affected by consumption level, industrial structure, digital infrastructure, digital governance level, opening level, and the relative difference of mobile digital equipment. Finally, this paper puts forward some suggestions, such as accelerating the construction of digital infrastructure, promoting the digital transformation of industry, and cultivating digital quality.
