摘　　要：数字经济是中国经济发展的新动能,也是当前扩大内需的重要着力点。论文分析了数字经济影响居民消费的机理,并基于2011-2020年中国省级面板数据,采用中介效应模型和空间杜宾模型检验了数字经济对居民消费的作用机制与空间效应,并从时间和区域维度做了拓展分析。结果表明:①数字经济能够直接促进居民消费;②数字经济促进消费的间接作用表现为在供给侧提升产品多样性,在需求侧提高居民收入,在市场侧促进市场一体化;③数字经济不仅驱动了本地消费,还对经济水平相近省份的消费产生了正向溢出效应;④拓展分析结果显示,数字经济驱动消费的作用随经济水平提高而增强,具有时间可持续性,同时该作用在中西部地区强于东部地区,呈现更有利于欠发达地区的益贫式特征。研究结果拓展了数字经济驱动居民消费的研究视角,并为依托数字经济提振消费需求提供了决策参考。The digital economy is a new driving force for China's economic development and an important growth point for expanding domestic demand.This study examined the mechanism of the digital economy affecting household consumption.Based on the panel data of 31 provinces of China from 2011 to 2020 and using the mediation effect model and the spatial Durbin model,this study examined the mechanism and spatial effects of the digital econo-my on household consumption and conducted an expanded analysis from the temporal and regional dimensions.The results show that:1)The digital economy can directly promote household consumption.2)The indirect effect of the digital economy on consumption is to improve the diversification of products on the supply side,increase household in-come on the demand side,and promote market integration on the market side.3)While promoting local consumption,the digital economy also has positive spillover effects among provinces with similar economic levels.4)The results of the expanded analysis show that the role of the digital economy in driving consumption is sustainable over time,which increases with the improvement of the economic level.Meanwhile,the effect is stronger in the central and western re-gions than in the eastern region,showing the characteristics of benefiting the poor and favoring the less developed re-gions.These results expanded the research perspectives of digital economy driving consumer consumption,and pro-vide a decision reference for the strategy of boosting consumer demand based on the digital economy.
