数字经济投入产出表文献综述

Literature Review on Input-Output Tables of Digital Economy

摘要: 在数字技术与实体经济深度融合的新时代，数字经济已成为重塑全球产业格局、驱动国民经济高质量发展的核心引擎，其内部细分领域的协同演进与对传统产业的渗透赋能，正深刻改变着产业间的关联形态与资源配置逻辑。本文对数字经济概念界定、测度方法及投入产出表的相关文献进行系统梳理，以挖掘现有研究的关注重点及需要进一步拓展的领域，为进一步的数字经济投入产出表的编制奠定基础。文献分析发现：目前国内外学者对于数字经济核算方法的研究成果丰硕，主要有指数测度法、编制数字经济卫星账户及投入产出法。相较于投入产出法，其他核算方法难以精确衡量数字经济的经济总量与产业结构，在深入揭示数字部门与非数字部门之间的技术经济联系与产业关联方面存在局限。此外，现有数字经济投入产出表编制存在分类标准贴合度低、部门拆分精度不足等问题。后续研究需遵循统一统计分类，精细化拆分投入产出表部门，深入探究数字经济与非数字部门的动态关联及增长赋能机制。

Abstract: In the new era of the deep integration of digital technology and the real economy, the digital economy has become the core engine for reshaping the global industrial landscape and driving the high-quality development of the national economy. The coordinated evolution of its internal sub-sectors and the penetration and empowerment of traditional industries are profoundly changing the inter-industry connection patterns and resource allocation logic. This paper systematically reviews the literature on the concept definition, measurement methods, and input-output tables of the digital economy to identify the focus of existing research and areas that need further exploration, laying the foundation for the subsequent compilation of the digital economy input-output table. The literature analysis reveals that scholars at home and abroad have achieved rich research results on the accounting methods of the digital economy, mainly including index measurement methods, the compilation of digital economy satellite accounts, and input-output methods. Compared with the input-output method, other accounting methods have difficulty in accurately measuring the economic aggregate and industrial structure of the digital economy and have limitations in deeply revealing the technical and economic connections and industrial correlations between digital and non-digital sectors. In addition, the existing compilation of digital economy input-output tables has problems such as low consistency of classification standards and insufficient precision in departmental breakdown. Future research should follow unified statistical classification, refine the breakdown of input-output table departments, and deeply explore the dynamic correlations and growth empowerment mechanisms between the digital and non-digital sectors.
