| With the progress of China’s information technology,China’s e-commerce has developed rapidly.The development of e-commerce has not only promoted economic growth,but also promoted the optimization of China’s industrial structure and the improvement of urban and rural consumption levels.As an emerging industry of China’s economic growth,e-commerce has the characteristics of low cost and high efficiency.E-commerce has brought new development opportunities and development directions to China’s towns and villages,which can promote the development of cities and villages and help narrow the gap between urban and rural consumption.Studying the impact of e-commerce on the gap between urban and rural consumption is helpful to understanding the status of e-commerce in economic development,and has important theoretical value and practical significance for promoting the overall improvement of residents’ consumption level and the narrowing of the gap between urban and rural residents’ consumption,thereby promoting common prosperity.First of all,this paper refers to the research on the measurement of the development level of e-commerce,and on the basis of drawing on the existing literature,adds the secondary indicators of e-commerce procurement amount,fiber optic cable line length,total length of postal routes,the number of websites owned by enterprises,and the proportion of postal administrative villages,and constructs 16 secondary indicators to measure the development level of e-commerce from four aspects: transaction level,basic ability,industry atmosphere and development potential.This paper collects the relevant data of 31 regions in China from 2014 to 2018,and uses the entropy method to establish the index weight according to the index system constructed,and calculates the e-commerce development index in various regions of China.According to the calculation,the development of e-commerce in various regions of China was analyzed from the two levels of e-commerce development index and 4 dimension index.For the e-commerce development index,this paper analyzes the gradient division,ranking change,and equilibrium level.According to the size and ranking of the e-commerce development index calculated,each region is divided into a pilot area,a backbone region,and a development potential area.The pilot areas are mainly concentrated in the coastal areas,such as Guangdong,Shanghai,Jiangsu and Zhejiang;while the development potential areas are concentrated in the remote areas in the west,such as Gansu,Ningxia,Tibet and Qinghai;most of the central areas are the backbone areas,such as Hunan,Hubei,Jiangxi,etc.Overall,there were no significant changes in the structural level of e-commerce development in various regions during the period from2014 to 2018.The small change in the ranking of the e-commerce development index in each region during the period from 2014 to 2018 indicates that the development of e-commerce in various regions was relatively stable during the period.By comparing the relationship between the e-commerce development index and the average level in various regions in the period from 2014 to 2018,it can be concluded that a small number of regions such as Guangdong Province,Beijing Municipality,Zhejiang Province,Shanghai Municipality,Jiangsu Province,Shandong Province,Fujian Province,and Sichuan Province have their e-commerce development index above the average,and the e-commerce development index in most regions is below the average level.Comparing and analyzing the various dimensions of the e-commerce development index,it can be concluded that the development advantages of regions with higher ecommerce development indexes,such as Guangdong,Shanghai,Jiangsu and Zhejiang,are mainly reflected in the two aspects of development potential and transaction level;while the development disadvantages of regions with low e-commerce development indexes such as Gansu,Ningxia,Tibet and Qinghai are mainly reflected in infrastructure.Secondly,this paper is the first to use spatial Durbin and panel threshold models to empirically study the impact of e-commerce on the gap between urban and rural consumption.From the perspective of local effects,the development of e-commerce is conducive to narrowing the gap between urban and rural consumption;the degree of urbanization,infrastructure,human capital and several control variables are also conducive to narrowing the gap between urban and rural consumption.From the perspective of the neighbor effect,the spatial lag coefficient of e-commerce on the gap between urban and rural consumption is significantly negative,indicating that the development of e-commerce in neighboring areas is conducive to narrowing the gap between local urban and rural consumption;the degree of urbanization and infrastructure development in neighboring areas are also conducive to narrowing the gap between local urban and rural consumption.The analysis results of the panel threshold model show that the impact of the development of e-commerce on the gap between urban and rural consumption has a single threshold effect with human capital and economic development level as the threshold variables.When human capital is less than or equal to the threshold value of 2.1245,the development of e-commerce helps to narrow the gap between urban and rural consumption,and when human capital is greater than the threshold of 2.1245,the development of e-commerce will inhibit the narrowing of the gap between urban and rural consumption.When the economic development level is less than or equal to the threshold value of 10.3254,the impact coefficient of e-commerce on the gap between urban and rural consumption is 0.9619;when the economic development level is greater than the threshold value of 10.3254,the impact coefficient of e-commerce on the gap between urban and rural consumption is 0.196.This shows that when human capital and economic development are at different levels,the impact of e-commerce on the gap between urban and rural consumption is different.Finally,this paper puts forward relevant suggestions for promoting the development of e-commerce in China and narrowing the gap between urban and rural consumption. |
