摘要: 数字经济是制造业产业升级重要驱动力量.基于2010—2019年长三角地区41个地级市的面板数据,利用熵权法分别测算了长三角制造业转型升级水平、数字经济发展程度,然后借助面板门槛模型实证分析了长三角地区数字经济发展对制造业转型升级的非线性影响.结果表明:长三角地区数字发展水平和制造业转型升级水平总体呈上升趋势.数字经济对制造业水平的快速发展表现出显著的正向影响且存在双门槛效应.当数字经济发展处于低级水平,表现为对制造业产业升级的抑制作用;当数字经济跨越第一门槛值,对制造业产业升级发挥出最大的促进作用;当数字经济跨越第二门槛值时,其对制造业产业升级的促进作用会减弱.

Abstract: Digital economy is an important driving force for manufacturing industry upgrading. Based on the panel data of 41 prefecture-level cities in the Yangtze River Delta region from 2010 to 2019, the level of transformation and upgrading of manufacturing industry and the degree of development of digital economy in the Yangtze River Delta were measured separately using the entropy weight method, and then the non-linear influence of digital economy development on the transformation and upgrading of manufacturing industry in the Yangtze River Delta region was analyzed empirically with the help of the panel threshold model. The results show that the digital development level and the transformation and upgrading level of manufacturing industry in the Yangtze River Delta region generally show an upward trend; the digital economy shows a significant positive influence on the rapid development of manufacturing industry and there is a double threshold effect, when the digital economy development is at a low level,which shows an inhibitory effect on the upgrading of manufacturing industry. When the digital economy crosses the first threshold, it plays the greatest role in promoting the upgrading of manufacturing industry, however, when the digital economy crosses the second threshold, its role in promoting the upgrading of manufacturing industry will be weakened.

Key words: Yangtze River Delta, digital economy, manufacturing industry upgrading, panel threshold mode
