数字经济发展水平对我国出口贸易的影响研究——以RCEP各国为例
Research on the Impact of the Development Level of Digital Economy on China’s Export Trade—A Case Study of RCEP Countries

本文采用2011年至2021年间中国对RCEP成员国出口贸易的面板数据作为研究对象，聚焦于基础设施、产业化水平及科研环境这三大关键因素，构建了一个衡量数字经济发展程度的指标体系。基于此，本研究进一步开发了一个扩展的引力模型来探讨数字经济的发展如何影响中国对RCEP成员国的出口贸易。通过实证分析，本研究揭示了RCEP成员国之间在数字经济发展水平上的显著差异，这种差异呈现出鲜明的两极分化趋势。研究还发现，东道国的数字经济发展水平越高，对中国出口的促进作用越明显。基于这些发现，本文提出两项建议：一是支持并帮助RCEP成员国中的发展中国家加强数字基础设施建设；二是促进数字技术创新与研发环境的优化；三是加强数字经济发展水平的评估与监测。
This paper adopts the panel data of China’s export trade to RCEP member countries between 2011 and 2021 as the research object, focusing on three key factors, namely, infrastructure, industrialization level and research environment, to construct an indicator system to measure the degree of development of the digital economy. Based on this, this study further develops an extended gravity model to explore how the development of digital economy affects China’s export trade to RCEP member countries. Through empirical analysis, this study reveals significant differences in the level of digital economy development among RCEP member countries, which show a sharp polarization trend. The study also finds that the higher the level of digital economy development in the host country, the more obvious the promotion effect on China’s exports. Based on these findings, this paper puts forward two recommendations: first, to support and help developing countries in RCEP member countries to strengthen the construction of digital infrastructure; and second, to promote the optimization of digital technology innovation and R&D environment. The third is to strengthen the assessment and monitoring of the level of development of the digital economy.
