摘要在中国经济增长新旧动能转换之际,数字经济赋能传统制造业逐渐成为长三角地区经济高质量发展的强大驱动力。文章在分析数字经济对制造业转型升级影响机理基础上,利用2015—2019年苏浙沪皖全域41个地级市面板数据,基于熵值法测度样本城市的制造业升级水平和数字经济发展水平,并运用动态面板GMM模型测算了数字经济对制造业升级水平的具体效应,同时利用中介效应模型识别其实现路径。实证结果表明,总体上数字经济赋能制造业转型升级效应和路径显著。具体来看,数字经济通过资源配置优化效应、生产成本降低效应和创新发展驱动效应三条路径推动制造业转型升级。从地理区位异质性上看,由于江苏、浙江产业基础、技术能力和资金较为充裕,数字经济对两地制造业转型升级的影响更为突出。 At the time of the transformation of new and old kinetic energy in China’s economic growth,the digital economy enabling manufacturing industry is gradually becoming a powerful driving force for high-quality economic development in the Yangtze River Delta.Based on the analysis of the influence mechanism of digital economy on the transformation and upgrading of manufacturing industry this paper uses the panel data of 41 prefecture level cities in Jiangsu,Zhejiang,Shanghai,and Anhui from 2015 to 2019 to measure the upgrading level of manufacturing industry and the development level of digital economy of sample cities based on Entropy method,and uses the dynamic panel GMM model to measure the specific effect of digital economy on the upgrading level of manufacturing industry.At the same time,the mediating effect model is used to identify its implementation path.The empirical results show that on the whole,the transformation and upgrading effect and path of manufacturing industry are significant.Specifically,the digital economy promotes the transformation and upgrading of manufacturing industry through three paths:resource allocation optimization effect,production cost reduction effect,and innovation development driving effect.From the perspective of geographical heterogeneity,due to the abundant industrial base,technological capacity and capital in Jiangsu and Zhejiang,the impact of digital economy on the upgrading of manufacturing level in Jiangsu and Zhejiang is more prominent.
