摘要
信息化发展和产业结构升级有助于全要素生产率提升。为明确三者间关系,基于2001-2016年中国264个地级市的面板数据,采用面板固定效应模型,实证分析信息化对产业结构升级的影响;同时利用面板分位数回归模型,考察产业结构升级对全要素生产率的非线性影响。研究发现,信息化能促进产业结构合理化和高级化。随着产业结构趋于合理化和高级化,全要素生产率得以提升,但这种提升效应是非线性的。产业结构合理化对全要素生产率增长的促进作用随分位数的提升而减弱,而产业结构高级化随之增强。同时,信息化能通过促进产业结构合理化对经济发展水平较低地区全要素生产率产生正向影响,而通过提升产业结构高级化对经济发展水平较高地区的全要素生产率产生正向影响。
Informatization and industrial structure upgrading help improve total factor productivity.To clarify the relationship between informatization,industrial structure upgrading,and total factor productivity,this paper adopts the panel data of 264 prefecture-level cities in China from 2001 to 2016,and the fixed effect model to analyze the impact of informatization on the industrial structure upgrading.At the same time,the panel quantile regression model is used to empirically analyze the nonlinear impact of industrial structure upgrading on total factor productivity.The results show that informatization can promote the rationalization and advancement of industrial structure.With the industrial structure tends to be rationalized and advanced,total factor productivity has been improved.However,this impact is nonlinear.In specific,the improvement effect of industrial structure rationalization on total factor productivity decreases with the increase of quantiles,while industrial structure advancement increases.In a word,informatization has a positive impact on total factor productivity by promoting industrial structure rationalization in less developed areas,and has a positive impact on total factor productivity by promoting industrial structure advancement in more developed areas.
