推进数字经济与实体经济深度融合和促进数字经济在产业层面交融互动，是发挥数字经济的优势、推动经济高质量发展的关键。基于投入产出表和经济普查数据，在识别数字经济核心产业的基础上，建立以技术经济联系为导向的产业网络，制定了从数字经济的供给端和需求端对数字经济的产业融合程度、路径和模式进行统计测度的研究框架，并实证分析了现阶段中国数字经济产业融合的主要特征。研究结果显示：(1)数字产品制造业与其他产业的前、后向融合程度都较高，对经济系统兼具较强的供给推动和需求拉动作用；数字产品服务业、数字技术应用业、数字要素驱动业与其他产业的融合程度相对较低，且以后向融合为主。(2)数字产品制造业占据产业链枢纽位置，尤其是高端装备制造业对其有较强的路径依赖；数字产品服务业、数字技术应用业、数字要素驱动业大多位于商务服务业和金融业的下游，获得了大量的商务服务和资金支持。(3)数字产品制造业与其他产业的融合既存在以技术经济溢出为主的“主溢出”模式，也存在以技术经济传递为主的“双向溢出”模式；数字产品服务业、数字技术应用业、数字要素驱动业与其他产业的融合表现为“数字孤岛”模式。

Advancing the deep integration of the digital and physical economies and promoting interactivity at the industrial level are crucial for leveraging the advantages of the digital economy and fostering high-quality economic development.Based on input-output tables and economic census data, and identifying core industries within the digital economy, a technology-economic network is constructed to discuss methods for statistically measuring the degree, pathways, and models of industry integration from both the supply and demand sides of the digital economy.An empirical analysis of the current main characteristics of China's digital economy industry integration is conducted.The empirical results reveal:(1) The manufacturing of digital products exhibits high levels of both forward and backward integration with other industries, providing strong supply-side impetus and demand-side pull; digital product services, digital technology applications, and digital factor-driven industries show relatively lower degrees of integration, primarily characterized by backward integration.(2) The manufacturing of digital products occupies a pivotal position in the industry chain, particularly dependent on the path of high-end equipment manufacturing; digital product services, digital technology applications, and digital factor-driven industries are generally positioned downstream of business services and finance, receiving extensive support in terms of business services and funding.(3) The integration of the manufacturing of digital products with other industries manifests as both a ‘main spillover' mode dominated by technology-economic spillovers and a ‘bidirectional spillover' mode characterized by technology-economic transfers; the integration of digital product services, digital technology applications, and digital factor-driven industries with other industries tends to exhibit a pattern of digital isolation.This research provides a new perspective on statistical measurement methods for exploring the integration of the digital economy with various industries, and based on the findings, offers policy insights for further enhancing the level and quality of China's digital economy industry integration.
