| In the 21st century,the digital economy has become a key force for reorganizing factor resources,reshaping economic structure,and changing the competitive pattern,and gradually penetrates into the whole process of economic and social development.The proposal of the new development pattern of "domestic circulation as the mainstay,domestic and international dual circulation" reveals that the digital economy has become an indispensable and important link in the new development pattern.The digital economy takes the upgrading of residents’ consumption as an opportunity to meet residents’ requirements for high quality of consumer goods,thereby promoting the construction of domestic circulation and releasing the vitality of economic growth.This paper studies the direct and indirect effects of the digital economy on household consumption.The digital economy precisely locates consumer demand and promotes direct consumption by residents by alleviating information asymmetry,strengthening demonstration effects,and creating new supply sides of products.By accumulating human and social capital,improving regional circulation efficiency,stimulating enterprise innovation power,and promoting industrial agglomeration and industrial integration,residents’ income will be increased and indirectly affect residents’ consumption.Mechanism analysis shows that the digital economy promotes household consumption,and household income is the mediating variable of the digital economy affecting household consumption.In the analysis of the current situation of digital economy and household consumption,with the continuous development of the digital economy,the gap between regions in the development of the digital economy has gradually narrowed,the growth rate of high-value regions has slowed down,and the growth rate of low-value regions has increased,but there is an obvious "Matthew effect" in interregional digital efficiency.Among the per capita consumption expenditure,the per capita consumption expenditure of residents showed an overall upward trend,the per capita consumption expenditure in the eastern region was higher than the national average,and the northeastern,central and western regions were lower than the national average,and there were differences in the consumption type expenditure of different regions.This paper uses scatter plot and fitting curve to further find that there is a positive correlation between digital economy and household consumption,and household consumption increases with the improvement of digital economy development level.Finally,the inward relationship between digital economy and household consumption is empirically tested by constructing a quantitative model.The results show that,first,the digital economy has a significant role in promoting household consumption,and the impact coefficient of rural residents’ consumption is higher than that of urban residents.Second,the results of the regression of the intermediary effect show that from the national level,the digital economy promotes the growth of residents’ income to increase residents’ consumption,and there is a complete mediation effect in the process of residents’ income,and the regression results of the intermediary effect of urban residents are consistent with the results.The intermediary effect of rural residents’ income in the process of digital economy promoting residents’ consumption is not significant.In addition,the impact of the digital economy on residents’ income is significantly positive,and the promotion effect of urban residents is greater than that of rural residents.Third,in the analysis of the regional heterogeneity of the impact of the digital economy on the consumption expenditure of urban and rural residents,the promotion effect of consumption expenditure of urban and rural residents in the east is significant,the digital economy in the central and western regions has a significant role in promoting the consumption expenditure of rural residents,and the impact coefficient of consumption expenditure of urban and rural residents in the northeast region is not significant.In the analysis of the heterogeneity of household consumption types,the impact coefficient of digital economy on subsistence,development and enjoyment household consumption expenditure was significant,and the survival consumption expenditure of urban residents was higher than that of rural residents,while the development and enjoyment consumption expenditure were the opposite. |
