数字经济如何影响先进制造业与生产性服务业融合?

How Does the Digital Economy Affect the Integration of Advanced Manufacturing and Producer Services?

基于2011-2020年省际面板数据,采用熵值法测算先进制造业与生产性服务业融合度,运用基准面板模型、中介效应模型和门槛模型考察数字经济对先进制造业与生产性服务业融合的影响及其机制。结果表明:数字经济显著促进先进制造业与生产性服务业融合,具有稳健性;数字经济通过模仿创新与自主创新对先进制造业与生产性服务业融合产生的中介效应显著弱于直接效应,技术引进不能成为数字经济促进先进制造业与生产性服务业融合的有效路径;数字经济对先进制造业与生产性服务业融合的促进作用呈现出“边际效应”非线性递增特征,当人力资本水平跨越门槛值后,数字经济对先进制造业与生产性服务业融合的促进作用持续增强。

Based on the inter-provincial panel data from 2011 to 2020,entropy method is used to calculate the integration degree of advanced manufacturing and producer services.Benchmark panel model,mediating effect model and threshold model are used to investigate the impact of digital economy on the integration of advanced manufacturing and producer services and its mechanism.The results show that digital economy significantly promotes the integration of advanced manufacturing and producer services,which is robust.The mediating effect of digital economy on the integration of advanced manufacturing and producer services through imitation innovation and independent innovation is significantly weaker than the direct effect.Technology introduction cannot be an effective way for digital economy to promote the integration of advanced manufacturing and producer services.The promoting effect of digital economy on the integration of advanced manufacturing and producer services shows a nonlinear increasing feature of “marginal effect”.When the level of human capital crosses the threshold value,the promoting effect of digital economy on the integration of advanced manufacturing and producer services continues to strengthen.
