数字经济增加值测算问题研究综述

Review on Measurement of Value Added of the Digital Economy

数字经济增加值是反映数字经济发展规模及其对整体经济贡献程度的重要统计指标.当前,国际上关于数字经济的概念、范围和增加值测算方法,还处于探索过程中,尚未达成统一的意见和一致的方法,从而不同的机构和学者测算的数字经济增加值结果差异较大.本文系统梳理了窄口径和宽口径的数字经济概念和范围界定,详细归纳了GDP核算中的生产法、基于增长核算框架的方法和计量经济学方法三种数字经济增加值测算方法,对比了目前国际上具有较大影响力的中国和美国数字经济增加值测算结果.在此基础上,总结数字经济增加值测算面临的挑战,并提出相应的对策建议,尝试为完善数字经济增加值测算方法,提高测算结果的可比性,为我国制定数字经济政策和促进数字经济高质量发展提供参考.

The value added of digital economy is an important statistical indicator reflecting the development scale of digital economy and its contribution to the overall economy.So far,the concept,scope and measurement methods of digital economy are still in the process of exploration,there’s no unified opinions and consistent measurement methods.Thus,there are significant differences between the results of digital economy value added that calculated by different academic institutions and scholars.This paper systematically combs the definition of digital economy form narrow scope and wide scope;summarizes three method of digital economy value added:Production method in GDP accounting,method based on growth accounting framework and econometric method;compares the results of the value added of digital economy of the United States and China,which have relative importance in the world.Finally,this paper summarizes the challenges,and puts forward corresponding suggestions.Try to improve the calculation method of value added of digital economy and the comparability of calculation results,meanwhile,attempt to provide reference to formulate digital economy policies and promote the high-quality development of digital economy.
