互联网使用与农户收入不平等

摘要基于2017年中国综合社会调查(CGSS)数据,采用内生转换模型对互联网使用与农户收入不平等的关系及其内在作用机制进行实证分析。研究发现:互联网使用缓解了农户收入不平等,基于反事实假设情景看,实际未使用互联网的农户若选择使用互联网,其收入不平等水平将下降21.4%;互联网使用对农户收入不平等的影响存在异质性,女性、中年和家庭经济状况低于平均水平的农户通过互联网降低收入不平等的作用更大;基于反事实假设看,初中及以下受教育程度或家庭经济状况低于平均水平的实际未使用互联网的农户,若选择使用互联网,其收入不平等水平下降幅度更大,若其实际使用互联网而选择不使用,其收入不平等水平将明显提高。在替换解释变量和估计方法后,上述研究结论仍然稳健。互联网使用通过信息效应和就业效应两条路径间接作用于农户收入不平等;其中信息效应具有完全中介效应,就业效应具有部分中介效应。

关键词：互联网使用农户收入不平等内生转换模型反事实假设

Abstract： Based on the data of 2017 China Comprehensive Social Survey (CGSS), this paper uses the endogenous transformation model to empirically analyze the relationship between Internet use and farmers' income inequality and its internal mechanism. The results are listed as follows. The use of the Internet has alleviated the income inequality of farmers. Based on the counterfactual hypothesis, if the farmers who do not use the Internet choose to use the Internet, their income inequality will decrease by 21.4%. There is heterogeneity in the impact of Internet use on farmers' income inequality, which is shown by the fact that female, middle-aged and below-average household economic conditions play a greater role in reducing income inequality through the Internet. Based on the counterfactual hypothesis, if farmers who are educated in junior high school or below or whose family economic status is lower than the average choose to use the Internet, their income inequality will decline even more. And if they actually use the Internet and choose not to use it, their income inequality will increase significantly. After replacing explanatory variables and estimation methods, the results are still robust. Besides, the study finds that Internet indirectly affects farmers' income inequality through information effect and employment effect, in which the information effect has a complete intermediary effect and the employment effect has a partial intermediary effect.
