摘要
文章在对比分析目前测度企业全要素生产率的6种主要方法的基础上,采用2001—2019年上市公司数据,对我国数字企业全要素生产率进行统计测度,深度解析省域数字企业全要素生产率发展水平及其时空格局。结果表明:相对于OP方法、OPACF方法和LPACF方法,LP方法、WRDG方法和MrEst方法能更加有效地缓解传统估计过程中出现的内生性、样本选择等问题;从时间维度来看,2001—2019年全国及东、中、西部地区数字企业全要素生产率整体平稳增长,不同地区数字企业全要素生产率呈现缓慢向平均水平收敛态势;从空间维度来看,2001—2019年东部地区数字企业持续在全国范围内发挥引领和示范作用,地区内部数字企业全要素生产率差异程度平稳缩小,中部地区数字企业全要素生产率差异总体有扩张态势,不同数字企业之间全要素生产率差距逐渐变大,西部地区数字企业全要素生产率发展较为曲折,内部发展不平衡问题日益凸显。
Based on the comparative analysis of six main methods for measuring enterprise total factor productivity(TFP)at present,this paper uses the data of listed companies from 2001 to 2019 to carry out statistical measurement of TFP in Chinese digital enterprises,and deeply analyzes the provincial development level and spatial-temporal pattern of TFP of digital enterprises.The results go as below:Compared with OP method,OPACF method and LPACF method,LP method,WRDG method and MrEst method can more effectively alleviate the problems of endogeneity and sample selection in the traditional estimation process.From the perspective of time dimension,the TFP of digital enterprises in China and eastern,central and western regions grew steadily from 2001 to 2019,and the TFP of enterprises in different regions converged slowly to the average level.From the perspective of spatial dimension,from 2001 to 2019,digital enterprises in the east continued to play a leading and exemplary role in the country.The TFP difference of digital enterprises within the region was steadily reduced,while the TPF difference of digital enterprises in the central region was generally expanding,and the TPF gap between different digital enterprises was gradually widened.The development of total factor productivity of digital enterprises in western China was tortuous,and the imbalance of internal development became increasingly prominent.
