信息基础设施的经济增长和收入分配效应研究——来自我国省际面板数据的经验分析

Study of Economic Growth and Income Distribution Effect of Information Infrastructure——Empirical Analysis of Provincial Panel Data from China

选取2006~2014年中国31个省市的面板数据,建立基于C-D生产函数的双固定效应模型,研究信息基础设施对经济增长的贡献和对资本要素以及劳动要素收入分配的影响。结果表明,固定长途电话交换机容量、长途光缆线路长度和互联网宽带接入端口的产出弹性为正,对经济增长起促进作用;局用电话交换机容量和移动电话交换机容量的产出弹性为负,对经济增长起阻碍作用。此外,信息基础设施的五项指标都会不同程度地加大要素收入分配差距。

A panel data of 31 provinces during year of 2006 to 2014 in China is chosen to set a double fixed effect model based on the C-D production function to study the contribution of information infrastructure to economic growth and the effect of information infrastructure to capital and labor income allocation. The results shows that the positive output elasticity of the fixed telephone exchange capacity,long-distance optical cable line length and broadband lnternet access ports can promote economic growth;while the negative output elasticity of telephone exchange capacity and mobile telephone exchange capacity can hinder economic growth. In addition,the five indicators of information infrastructure will increase the income distribution gap to varying degrees.
