摘要
协调发展是"五大发展理念"的重要组成部分,收入不平等是其中一个重要的研究议题。近十年来互联网发展深度影响着中国的经济增长和产业转型,同时也可能对收入分配产生影响。本文从各省内行业间工资差距角度,研究互联网普及对工资差距的影响,结果表明:使用两阶段最小二乘法排除内生性后,互联网普及可以显著地减小各省份行业间的工资差距,并且提高了省份和行业层面的工资水平;互联网普及减小工资差距的积极作用主要发生在中西部地区或者低经济发展水平地区,与各地区初始工资差距大小存在差异有关;使用中介效应模型检验发现,互联网普及可以通过提高地区产业集聚程度和创新水平进而降低工资差距;拓展性分析发现,互联网普及与产业结构转型之间存在显著的交互作用,但是主要体现在产业结构合理化方面,产业结构越合理,则互联网普及减小工资差距的作用越大。
Coordinated development is an important part of the Five Development Concepts,while income inequality is an important research topic in it.In the recent 10 years,the development of Internet has a profound impact on China’s economic growth and industrial transformation and may also have an impact on income distribution.In this paper,from the perspective of wage gap among industries in various provinces,it is of great significance to study the impact of Internet popularization on wage gap.The results show that the Internet popularization can significantly narrow the wage gap between provinces and industries and increase the wage level after endogeneity was eliminated by two-stage least squares method(2 SLS).The positive role of Internet popularization in narrowing the wage gap mainly occurs in the central and western regions or regions with low level of economic development,which is mainly related to the difference of the gaps of initial wage between different regions.We use intermediary effect model and find that the popularity of Internet can narrow the wage gap by improving the degree of regional industrial agglomeration and the ability of innovation.Expanding analysis finds that a significant interaction exists between the Internet popularization and the industrial structural transformation,but the latter mainly shows on the rationalization of industrial structure.That is,the proper the industrial structure,the stronger the effect of Internet popularization will have on narrowing the wage gap.
