摘要
作为服务业中份额最大的门类行业,批发零售业在国民经济增长中发挥着重要作用.本文以2003年至2016年中国283个城市为研究样本,运用固定效应估计、系统GMM方法检验批发零售业发展对城市生产率增长的影响.研究结果发现:首先,批发零售业发展对城市劳动生产率的正向影响在统计上不显著,在采用系统GMM方法克服潜在的内生性问题后,这种正向作用变得显著;其次,批发零售业发展对城市全要素生产率增长具有显著的正向促进作用;最后,批发零售业发展会通过消费拉动效应、成本降低效应、就业带动效应与技术溢出效应促进城市生产率增长.
As the largest share of the service industry, the wholesale and retail trade plays an important role in the growth of the national economy. This paper takes 283 cities in China from 2003 to 2016 as research sample. Based on the review of related literatures, the relationship between wholesale and retail trade development and urban total factor productivity is tested by a fixed effect model. The study found that, firstly, the share of wholesale and retail trade employment has a significant positive effect on urban total factor productivity, that is, the development of wholesale and retail industry has significantly promoted the growth of regional total factor productivity. And the positive effect is further strengthened after dealing with endogenous problems. Secondly, the share of wholesale and retail trade has a positive effect on urban labor productivity, but this effect is not significant. After using the systematic GMM method to overcome potential endogenous problems, this positive effect becomes significant. Finally, the wholesale and retail trade development will promote the urban total factor productivity growth through consumption pull effect, cost reduction effect, employment drive effect and technology spillover effect.
