数字经济与制造业融合对区域经济高质量发展的影响研究——基于人工智能应用的中介效应
Research on the Impact of the Integration of Digital Economy and Manufacturing Industry on High Quality Development of Regional Economy—Mediating Effect Based on Artificial Intelligence Applications

近年来数字技术成为经济发展过程中的关键要素，制造业作为实体经济的主体，是推动经济高质量发展的主要力量之一，本文选取2014~2022年中国30个省份的面板数据，实证研究数字经济与制造业融合发展水平对区域经济高质量发展的影响。研究结果表明：数制融合程度对区域经济高质量发展具有显著的正向影响；机制检验表明，数制融合通过提高人工智能应用程度促进经济高质量发展。人力资本在数制融合促进经济高质量发展的过程中起到了正向调节的作用；拓展检验发现，数制融合对我国经济高质量发展的影响具有区域异质性。
In recent years, digital technology has become a key element in the process of economic development. As the mainstay of the real economy, manufacturing is one of the main forces driving high-quality economic development. This article selects panel data from 30 provinces in China from 2014 to 2022 to empirically study the impact of the integration of digital economy and manufacturing on the high-quality development of regional economy. The research results indicate that the degree of integration of numerical systems has a significant positive impact on the high-quality development of regional economy. Mechanism testing shows that the integration of numerical systems promotes high-quality economic development by increasing the degree of application of artificial intelligence. Human capital plays a positive regulatory role in promoting high-quality economic development through the integration of numerical systems. The expansion test found that the integration of numerical systems has regional heterogeneity in its impact on the high-quality economic development.
