长三角地区数字经济对高端装备制造业高质量发展的影响研究——基于有调节的中介效应分析

Study on Influence of Digital Economy on High-quality Development of High-end Equipment Manufacturing Industry in Yangtze River Delta Region

借助数字经济实现高端装备制造业高质量发展是中国式现代化建设的重要议题。本文基于长三角地区面板数据,利用有调节的中介效应模型检验了数字经济对高端装备制造业高质量发展的影响。结果发现:数字经济可以显著促进高端装备制造业高质量发展,稳健性检验后仍然成立;数字经济通过技术创新正向促进高端装备制造业高质量发展,且技术创新发挥部分中介效应;政府支持对技术创新的中介效应发挥正向调节作用;进一步异质性检验发现,数字经济对不同地区、不同细分行业高质量发展的影响存在显著差异。最后,从三个方面提出相关建议:构建全方位的区域协调发展机制,提升融合效能;聚焦重点领域,推动核心技术突破创新;聚焦制度创新,释放政策红利。

The high-quality development of high-end equipment manufacturing industry with the help of digital economy is an important issue in the construction of Chinese-style modernization.Based on the panel data of the Yangtze River Delta region,this paper uses a moderated mediating effect model to test the impact of digital economy on the high-quality development of high-end equipment manufacturing industry.The results show that the digital economy can significantly promote the high-quality development of high-end equipment manufacturing industry,which still holds after robustness test;digital economy is promoting the high-quality development of high-end equipment manufacturing industry through technological innovation,and technological innovation plays a part of mediating effect;government support plays a positive regulatory role in the mediating effect of technological innovation.Further heterogeneity test shows that there are significant differences in the impact of digital economy on high-quality development in different regions and different sub-sectors.Finally,this paper puts forward relevant suggestions from three aspects:building a comprehensive regional coordinated development mechanism to enhance integration efficiency;focusing on key areas and promoting breakthroughs and innovations in core technologies;focusing on institutional innovation and releasing policy dividends.
