摘要
互联网的高速稳定发展对经济社会活动产生了广泛而深远的影响。本文采用CFPS2010—2018年的动态面板数据,运用系统GMM方法考察互联网普及对中国消费差异的影响。研究发现,互联网普及显著地降低了中国地区消费差异程度,并且本文机制检验的结果表明,互联网普及能够通过缓解收入差异程度、降低居民消费价格指数两个渠道来缩小地区消费差距,这种抑制效应因不同收入水平、地理分布和发展特征而呈现鲜明的异质性。进一步地,本文基于消费维度衡量的贫困指标拓展分析互联网使用对家庭贫困的影响,从而验证了中国的互联网普及存在典型的“减贫效应”。本文研究的主要结论对进一步强化互联网基础设施建设、缓解中国消费差异程度以及助力脱贫攻坚具有重要意义。
The high-speed and stable development of the Internet has had a broad and far-reaching impact on economic and social activities.This paper uses dynamic panel data from CFPS 2010-2018 to examine the impact of Internet penetration on consumption disparity in China using a systematic GMM approach.It is found that Internet penetration significantly reduces the degree of regional consumption disparity in China,and the results of the mechanism test in this paper indicate that Internet penetration can reduce the regional consumption gap through two channels:alleviating the degree of income disparity and reducing the consumer price index,and this suppression effect shows distinct heterogeneity by income level,geographical distribution,and development characteristics.Further,this paper extends the analysis of the impact of Internet use on household poverty based on poverty indicators measured by the consumption dimension,thus verifying the typical’poverty reduction effect’of Internet penetration in China.The main findings of this paper have important implications for further strengthening the Internet infrastructure,alleviating consumption disparities in China,and contributing to poverty alleviation.
