针对现有文献在数字经济规模的测算方法方面存在的分歧,首先基于国家统计局发布的《数字经济及其核心产业统计分类(2021)》,明确了投入产出表中的部门分类与数字经济核心产业各细分行业的对应关系;然后基于官方发布的投入产出表及投入产出延长表、学者编制的时间序列投入产出表,结合历次经济普查数据,采取将数字经济核心产业各细分行业的增加值按比例从国民经济各行业增加值中剥离出来的做法,测算了中国 1981-2020 年数字经济核心产业的规模及其各细分行业的占比;并与代表性文献在同口径下进行了比较,验证了测算结果的稳健性.在此基础上,预测了"十四五"时期各年中国数字经济核心产业可能达到的规模及其各细分行业的占比,并对未来数字经济核心产业的发展趋势以及数字经济统计制度建设进行了展望.
Re-measurement of China's Core Industry Scale of Digital Economy
In view of the differences in calculation methods of the scale of digital economy in the existing literature,based on the Statistical Classification of Digital Economy and its Core Industries(2021)issued by the National Bureau of Statistics,the corresponding relationship between the classification of departments in the input-output table and the subdivisions of the core industries of digital economy is clarified.Then,based on the official input-output table and input-output extension table,the time series input-output table compiled by scholars,and combined with previous economic census data,the added value of each subsector of the core industry of the digital economy is separated from the added value of each industry of the national economy in proportion.China's core industries scale of digital economy and the proportion of each subsector during 1981-2020 are calculated.Compared with the representative literature,the robustness of the calculated results is verified.On the basis,it predicts the possible China's core industry scale of digital economy and the proportion of each sub industry in the 14th Five Year,and looks forward to the future development trend of the core industry of digital economy and the construction of the statistical system of the digital economy.
