数字贸易对人均消费支出的影响研究

The Impact of Digital Trade on Per Capita Consumption Expenditure

当前,数字贸易已成为促进居民消费的重要途径,研究数字贸易通过哪些途径对我国居民消费产生影响是理顺数字贸易与居民消费之间关系的关键任务。使用结构方程模型和中介效应检验方法,发现数字贸易能显著促进我国人均消费支出;人均可支配收入是数字贸易与人均消费支出的中介变量;外商投资调节了数字贸易与人均可支配收入的关系,外商投资规模大的地区的数字贸易发展水平更高;实际经济增长率调节了人均可支配收入与人均消费支出的关系,实际经济增速快的地区的人均可支配收入提升更快。因此,应制定政策,提高数字贸易竞争力,推动中西部地区产业结构调整,引进先进技术和关键设备,通过进口贸易技术溢出提升中西部地区创新水平。

Currently,digital trade is an important way to promote the consumption of residents.The key task of straightening out the relationship between digital trade and household consumption is to study the ways through which digital trade has an impact on China s residents consumption.Using structural equation model and mediating effect test method,it is found that digital trade can significantly promote China s per capita consumption expenditure.Per capita disposable income is the intermediary variable between digital trade and per capita consumption expenditure.Foreign investment regulates the relationship between digital trade and per capita disposable income,and the development level of digital trade in regions with large scale of foreign investment is higher.The real economic growth rate regulates the relationship between per capita disposable income and per capita consumption expenditure,and the per capita disposable income in the regions with rapid real economic growth increases faster.Based on the above findings,we put forward the following suggestions:improving the competitiveness of digital trade;promoting the adjustment of industrial structure in the central and western regions;introduce advanced technology and key equipment;and enhancing the innovation level of the central and western regions through the technology spillover of import trade.
