数字经济、普惠金融与制造高质量发展的关系研究

在对数字经济和制造业高质量发展相关文献进行述评的基础上，基于2011—2021年中国统计年鉴31个(因数据缺失，未包括港澳台地区)省份数据，研究数字经济对制造业高质量发展的影响，通过构建普通面板模型、中介效应模型、面板门槛效应模型和空间杜宾模型等进行分析。结果表明，数字经济正向促进了制造业的高质量发展；在数字经济对制造业高质量发展的推动下，普惠金融起到了关键的中介作用；在不同的经济发展水平下，数字经济对制造业高质量发展存在差异性，这种差异体现在数字经济对制造业高质量发展的促进作用在经济落后的地区体现得更加明显；数字经济对制造业高质量发展具有空间溢出，不仅对本地区具有促进作用，对邻近地区的制造业高质量发展也具有促进作用。

Research on the Relationship between Digital Economy, Pratt & Whitney Finance and Manufacturing Quality Development

Based on the literature review on digital economy and high-quality development of manufacturing industry, the impact of digital economy on high-quality development of manufacturing industry was researched based on the data of 31 provinces from 2011 to 2021, the common panel model, intermediary effect model, panel threshold effect model and Spatial Dubin model were constructed. The results are as follows. The digital economy promotes the high-quality development of the manufacturing industry. Pratt & Whitney plays a key intermediary role as the digital economy boosts the high quality of manufacturing. There are different levels of economic development between the digital economy and the high-quality development of the manufacturing industry in the developed regions, this difference is reflected in the promotion effect of the digital economy on the high-quality development of the manufacturing industry, which is more evident in economically underdeveloped areas. The digital economy has spatial spillover effects on the high-quality development of manufacturing industry, which not only promotes the local area but also promotes the high-quality development of manufacturing industry in neighboring areas.
