数字乡村建设对农村居民消费影响的异质性及特征

Heterogeneity and Characteristics of the Impact of Digital Village Construction on Rural Residents’Consumption

以我国31个省级行政区的面板数据为基础,对数字乡村发展进行评价,并采用双向固定效应模型进行分析,结果表明:数字乡村建设能够促进农村居民消费的提高,通过稳健性检验可知该影响存在时滞性;通过异质性分析发现,数字乡村建设对不同地区农村居民消费的正向促进作用始终存在且呈先升后降低的倒“U”形趋势的新特征,可能是数字乡村建设对农村居民消费影响的边际贡献递减和时滞性原因。

Based on the panel data of 31 provincial-level administrative regions in China,we evaluate the development of digital countryside and analyze it with a two-way fixed-effects model,which shows that:digital countryside construction can promote the consumption of rural residents,and through the robustness test,we can see that there is a time lag in the effect;through the analysis of heterogeneity,it is found that the positive promotion effect of digital village construction on the consumption of rural residents in different regions always exists and shows the new feature of inverted“U-shape”trend,which may be due to the marginal impact of digital village construction on the consumption of rural residents and the result of time lag.
