文章基于新兴古典经济学分析框架,构建了中国城乡分割条件下服务业发展与城乡收入差距变化的理论模型,并提出了随着城乡分割制度的消除,服务业的增长有利于缩小城乡居民收入差距的假设,然后利用省级面板数据证明了服务业发展有利于缩小城乡居民收入差距。此外,分位数回归中服务业的系数与动态面板回归具有相似性,不过在被解释变量的不同分位点上系数有所差异,在低分位点上服务业对城乡居民收入差距的负向作用更大。
Based on the new analysis framework of classical economics, the article constructs a theoretical model of the development of service industry and the income gap between urban and rural areas under the segmentation of urban and rural areas in China and proposes that with the elimination of urban-rural segregation system, the growth of service industry is beneficial to narrowing the income gap between urban and rural residents Hypothesis, and then use the provincial panel data to prove that the development of service industry is conducive to narrowing the income gap between urban and rural residents. In addition, the coefficients of service industry in the quantile regression are similar to those of dynamic panel regression, but the coefficients are different at different quantiles of the explained variables. At the low quantile, the service industry’s negative effect on the income gap between urban and rural residents To a greater role.
