摘要
研究目标:准确分析中国数字经济发展地区间的差异性和协调性以及数字经济发展与经济增长的关系。研究方法:基于全国工商企业注册微观数据,使用自然语言处理技术筛选出数字经济企业,在此基础上构建1994~2018年31个省份样本面板数据集,运用泰尔指数和协调度指数对省域间差异进行分析,并采用PVAR模型探讨了数字经济与经济增长之间的关系。研究发现:第一,从数字经济发展的基本情况看,数字经济企业的进入率明显高于退出率,且省际差异明显,数字经济处于不平衡且快速发展阶段。第二,从数字经济发展的地区差异性看,企业进入率的地区差异有所缩小,主因是地区内差异有所缩小,企业退出率的地区差异有所增加,主因是地区间差异有所增加。数字经济企业的进入率和退出率都以正向偏离为主,数字经济发展越快的地区,其经济规模越大。从数字经济发展的地区收敛性来看,在相邻省份层面,企业进入率的协调性处于较高水平,而企业退出率则处于较低水平,表明相邻省份间,数字经济发展在企业进入方面的模仿性更强。第三,从数字经济与经济增长的关系看,提高数字经济企业进入率和退出率,都有助于推动经济增长,提高企业进入率主要通过增强市场竞争的渠道推动经济增长,而提高企业退出率则主要是通过淘汰落后产能的渠道推动经济增长。研究创新:基于全国工商企业注册信息,创建了一套全样本的中国数字经济企业数据库,从多个视角刻画中国数字经济的演变过程和相关规律。研究价值:利用数字经济微观企业数据加总的产业口径相对精准地描述了中国数字经济的时空演变规律,为后续中国数字经济发展研究奠定了基础。
Research Objectives:This paper provides an accurate analysis of the inter-regional variability and coordination of Chinese digital economy development and the relationship between digital economy development and economic growth.Research Methods:Based on the microdata of the national business enterprise registration,we use natural language processing techniques to screen out digital economy enterprises.On this basis we construct a sample panel dataset of 31 provinces from 1994 to 2018.We analyze inter-provincial differences using the thiel index and the concordance index,then we use the PVAR model to explore the relationship between the digital economy and economic growth.Research Findings:Firstly,from the basic situation of the development of digital economy,the entry rate of digital economy enterprises is significantly higher than the exit rate,and the inter-provincial differences are obvious.This means that the digital economy is in an unbalanced and rapidly developing stage.Secondly,in terms of regional differences in the development of digital economy,the regional differences in the entry rate of enterprises have narrowed,mainly due to the narrowing of intra-regional differences,and the regional differences in the exit rate of enterprises have increased,mainly due to the increase in inter-regional differences.Both the entry and exit rates of digital economy firms are dominated by positive deviations.The faster the development of digital economy,the larger the size of the economy.In terms of regional convergence in digital economy development,the coordination of enterprise entry rates is at a higher level,while enterprise exit rates are at a lower level at the level of neighboring provinces,indicating that digital economy development is more imitative in terms of enterprise entry among neighboring provinces.Thirdly,in terms of the relationship between the digital economy and economic growth,increasing both the entry and exit rates of digital economy enterprises helps to drive economic growth.Increasing the entry rate of firms drives economic growth primarily through the channel of increased market competition,while increasing the exit rate of firms drives economic growth primarily through the channel of eliminating outdated capacity.Research Innovations:We create a full-sample database of Chinese digital economy enterprises to portray the evolution of Chinese digital economy and related patterns from multiple perspectives.Research Value:This paper relatively precisely describes the spatial and temporal evolution of Chinese digital economy.
