摘　　要：文章基于2013—2020年中国30个省份的面板数据,运用系统演化矢量耦合模型,测度了中国数字经济与制造业发展的耦合程度和增值能力。研究发现:中国数字经济与制造业耦合程度和系统增值能力持续提升,但不同省份之间存在显著差异,且系统耦合存在门槛效应。系统演化模式分析和模型分解结果表明,各省份数字经济与制造业系统增值能力呈现两极分化、中间断档的局面;数字经济对系统增值能力贡献显著,但制造业和两系统的耦合动力对系统增值能力的促进作用稍显不足。所以,只有全面推进数字经济、制造业及系统耦合发展才能提升系统增值能力。Based on the panel data of 30 provinces in China from 2013 to 2020,this paper uses the system evolution vector coupling model to measure the coupling degree and value-added capacity of China’s digital economy and the manufacturing development.The study finds that the coupling degree between China’s digital economy and manufacturing and system value-added capabilities continue to improve,but there are significant differences between different provinces,and there is a threshold effect in system coupling.The results of system evolution pattern analysis and model decomposition show that the value-added capabilities of digital economy and manufacturing systems in each province are polarized and interrupted in the middle,and that digital economy has made a significant contribution to system value-added capabilities,but the coupling dynamics between the manufacturing and the two systems have not played a sufficient role in promoting the system value-added capabilities.Therefore,only by comprehensively promoting the development of digital economy,manufacturing and system coupling can the value-added capability of the system be improved.
