【摘要】：基于2004—2011年的中国营养与健康调查数据(CHNS),本文使用最小二乘法和控制自选择偏差的倾向性得分匹配法详细估计了互联网使用对工资收入的影响。结果表明,互联网使用对个体工资收入有积极的影响,尤其对于拥有高中学历的个体而言,这种影响更大。本文进一步使用基于RIF回归的FFL分解方法考察了互联网使用对工资不平等的影响。本文发现,2004—2011年间互联网使用比例的增加降低了整体工资不平等,且使用过互联网的高中学历人员比例增加有助于降低高工资与中等工资收入人群的工资差距。同时,互联网使用收益率的下降也有助于降低工资不平等,尤其有助于降低高工资与中等工资收入人群之间的工资差距。因此,普及互联网使用,尤其是提高低收入群体的互联网使用比例和普及该群体的高中阶段教育对于抑制不平等的扩大有重要的意义。
[Abstract]:Based on the data of China Nutrition and Health Survey (CHNS),) from 2004 to 2011, this paper uses the least square method and the tendency score matching method to control self-selection deviation to estimate the impact of Internet use on wage income in detail. The results show that Internet use has a positive impact on individual wage income, especially for individuals with high school education. In this paper, the effect of Internet use on wage inequality is investigated by using FFL decomposition method based on RIF regression. This paper finds that the increase in the proportion of Internet use between 2004 and 2011 reduces the overall wage inequality and that the increase in the proportion of high school graduates who have used the Internet helps to reduce the wage gap between high and middle wage earners. At the same time, falling Internet use yields have also helped to reduce wage inequality, particularly between high-and middle-income earners. Therefore, universal Internet use, especially to increase the proportion of low-income groups of Internet use and to popularize the upper secondary education of this group, is of great significance to curb the expansion of inequality.
