摘  要:数字经济以其高渗透性特征正在与各大产业加速融合发展,成为推动我国经济高质量发展的重要动力。基于2013—2020年省际面板数据,建立个体时间固定效应模型和中介效应模型对理论假设进行检验。研究发现:数字经济发展对装备制造业转型升级具有正向促进作用,在将模型由静态模型更改为动态模型后结论依然成立;同时该促进作用在不同区域中具有明显差异,对东部地区的影响显著性要高于中西部地区;从中介效应检验结果发现:创新效率的中介效应存在,即数字经济—创新效率—装备制造业转型升级的机制成立。Digital economy,with its characteristic of high permeability,is accelerating integrated development with various industries and has become an important driving force for promoting the high-quality development of China′s economy.Based on the inter-provincial panel data from 2013 to 2020,an individual time fixed effect model and a mediation effect model were established to test the theoretical hypothesis.The research shows that the development of digital economy plays a positive role in promoting the transformation and upgrading of equipment manufacturing industry,and the conclusion is still valid after the model is changed from static model to dynamic model.At the same time,the promoting effect is obviously different in different regions,and the influence on the eastern region is more obvious than that on the central and western regions.The mediating effect test shows that the mediating effect of innovation efficiency is established.That is,the mechanism for the transformation and upgrading of the digital economy,innovation efficiency and equipment manufacturing industry has been established.

关 键 词:数字经济 装备制造业 转型升级 中介效应
