摘要
本文使用中国家庭金融调查(CHFS)2015年、2017年和2019年的家庭微观数据构造的面板数据,使用Tobit固定效应模型从微观家庭视角探讨了数字鸿沟对个体消费不平等的影响。研究发现,数字鸿沟显著增加了个体消费不平等,该结论经过一系列内生性处理与稳健性检验后依然成立。本文从收入不平等以及消费平滑渠道这两个角度,验证了数字鸿沟对个体消费不平等的作用机制。围绕“接入鸿沟”和“使用鸿沟”的研究发现,数字鸿沟对消费不平等的加剧作用在欠发达地区和数字弱势群体中更加突出。进一步的研究发现,数字鸿沟主要增加了更高层次消费的不平等。
Based on the panel data constructed from the China Household Finance Survey(CHFS) Data in 2015, 2017 and 2019, this paper uses a Tobit fixed effect model to explore the influence of digital divide on individual consumption inequality from the perspective of family. It is found that the digital divide has significantly increased individual consumption inequality, and the conclusion is still valid after handling the endogeneity problem and a series of robustness tests. The mechanism of digital divide on individual consumption inequality is verified from the perspectives of income inequality and consumption smoothing channels. Focusing on the research of “access gap” and “use gap”, it is found that the digital divide has a more prominent role in aggravating consumption inequality in underdeveloped areas and for vulnerable groups. Further research has found that the digital divide mainly increases the inequality in higher levels of consumption.
