数字技术创新赋能数字经济和实体经济深度融合模式——基于生产—消费网络的视角

The Deep Integration Mode of Digital Economy and Real Economy Empowered by Digital Technology Innovation——From the Perspective of Production-consumption Network

数字技术创新对新时期我国数字经济和实体经济的深度融合具有重要意义。本文基于生产—消费网络的视角,运用结构化模型对产业融合过程中数字技术创新的关联效应及其作用机制进行了反事实模拟,结果表明:第一,在生产—消费网络下,数字技术创新对实体产业的产出具有显著的正外部性影响;第二,数字产业与实体产业构成典型的“中心—外围”网络模式,中心挤出效应和边缘支撑效应并存;第三,数字技术创新通过改变生产、消费和劳动力供给等网络的完备性而最终影响到数字经济和实体经济的融合路径。本文研究得出的生产—消费网络的“中心—外围”模式及影响机制有助于明确现阶段我国数字经济和实体经济的竞合关系,从而为二者在新时期的深度融合提供可行方案。

Digital technology innovation is of great significance to the deep integration of digital economy and real economy in China.Founded on the production-consumption network,this paper exploits a structural model to perform counterfactual simulation on the correlation effect brought by digital technology innovation in the process of industrial integration,and draws three main conclusions.First,under the production-consumption network,digital technology innovation owns significant positive externality towards the output of real industries.Second,there is a typical center-periphery network connecting digital industries and real industries,with center crowding-out effect and edge supporting effect coexisting.Third,digital technology innovation affects the integration path of digital economy and real economy by altering the completeness of production,consumption and labor supply networks.The center-periphery mode and mechanism of production-consumption network contribute to clarifying the relationship between digital economy and real economy,and provide feasible solutions for their deep integration in the new era.
