The Scope and Method of Digital Economy Scale Accounting

数字经济已成为推动国民经济增长和经济高质量发展的“新引擎”。如何客观、准确、全面地核算数字经济规模及其对经济增长的贡献度是当前国民经济核算体系面临的重大课题。在对国内外数字经济核算范围和测度方法比较的基础上,充分考虑我国数字经济的活动情况,并结合我国国民经济产业分类的实际情况,构建符合我国国情的数字经济分类体系,运用投入产出分析方法测算出2017年数字经济规模为21.42万亿元,占GDP的比重达到26.09%。将相关机构测度的数字经济规模与测度数据进行比较,认为投入产出分析方法在衡量数字经济规模方面具有独特优势,并就数字经济核算的后续研究进行展望。
