数字经济、全国统一大市场与中国空间不平等
Digital Economy,the National Unified Market,and Spatial Inequality in China
摘要
Abstract
The unbalanced and insufficient economic development between regions is China's basic national conditions.In the context of the digital economy,with the rise of new technologies such as blockchain,the digital economy can not only directly affect spatial relationships,but also reshape spatial relationships through market integration and other channels.However,the existing literature has seldom included the digital economy and the national unified market in the unified analytical framework of regional spatial inequality,especially the effect and mechanism of the two influencing regional spatial inequality need to be further studied. In this paper,the neighbor relationship between regions is introduced into the traditional Gini coefficient,and the spatial Gini coefficient is constructed to measure the level of regional spatial inequality.At the same time,the entropy method is used to construct digital economy indicators,and the relative difference of factor prices to construct market integration indicators.The effects and mechanisms of the digital economy and the national unified market affecting spatial inequality in China are analyzed using data related to China's 30 provinces(excluding Hong Kong,Macao,Taiwan,and Tibet)from 2012 to 2022.The empirical study finds that both digital economy development and the construction of a national unified large market can significantly reduce the level of regional spatial inequality under a variety of adjacency relationships such as binary adjacency matrix,multiple distance matrix,economic distance matrix and cultural distance matrix.Specifically,digital economy development can not only directly reduce the level of regional spatial inequality,but also will further reduce the level of regional spatial inequality through the moderating and intermediary effects of the construction of a national unified large market,with both short-term and long-term effects.After using the common factor approach to deal with the impact of the endogeneity problem between the digital economy and spatial inequality,the conclusions are still robust. Compared with the previous literature,this paper expands in the following three aspects:first,it introduces the neighborhood relationship between regions into the traditional Gini coefficient,constructs a spatial Gini coefficient indicator,and enriches the measurement method of regional spatial inequality level.Second,the digital economy and the national unified market are included in the unified analytical framework,expanding the previous literature on the factors affecting spatial inequality in China from a new perspective.Third,on the basis of qualitative analysis of the digital economy and national unified large market affecting regional spatial inequality,quantitative analysis of the magnitude of the effect of the digital economy and national unified large market affecting regional spatial inequality and the mechanism of its action is conducted. To a certain extent,the research in this paper reveals the internal logic of the digital economy and national unified market affecting spatial inequality,which helps government departments to scientifically formulate plans for the development of the digital economy and the construction of the national unified market based on China's national situation of high levels of spatial inequality between regions,and helps China to weaken regional spatial inequality and realize common prosperity.关键词
