数字经济赋能制造业升级的影响效应研究

Research on Effect of Digital Economy Empowering Manufacturing Upgrading

当前,数字经济已成为助推我国经济社会发展的关键动力。我国制造业规模庞大、门类齐全,在实体经济中地位举足轻重,但商品供给结构和效率不适应消费需求升级的矛盾依然突出。加快推进数字经济与制造业融合发展,孕育发展新动能,用新动能推动制造业升级,为制造业高质量发展带来了新契机。本文借助2013—2020年省级面板数据,运用熵值法测度我国30个省(区、市,不含港澳台和西藏)的数字经济发展水平和制造业升级水平,并实证检验了数字经济赋能制造业升级的间接效应、中介效应和空间溢出效应。在此基础上,提出强化企业家精神引领作用、加大财政科技支出和发挥数字经济空间溢出作用等对策建议。

At present,the digital economy has become a key driving force for China's economic and social development.China's manufacturing industry is large in scale and complete in categories,and plays an important role in the real economy,but the contradiction that the structure and efficiency of commodity supply do not adapt to the upgrading of consumer demand is still prominent.Accelerating the integration and development of the digital economy and manufacturing industry,breeding the development of new kinetic energy,and promoting the upgrading of the manufacturing industry with new kinetic energy has brought new opportunities for the high-quality development of the manufacturing industry.With the help of provincial panel data from 2013 to 2020,this paper utilizes the entropy value method to measure the level of digital economy development and manufacturing upgrading in 30 provinces(autonomous regions,municipalities,excluding Hong Kong,Macao,Taiwan and Tibet)on the mainland of China,and empirically examines the indirect effect,mediating effect and spatial spillover effect of the digital economy empowering the upgrading of the manufacturing industry.On this basis,countermeasures and suggestions are put forward to strengthen the leading role of entrepreneurship,increase fiscal spending on science and technology,and give play to the spillover role of the digital economy.
