数字新质生产力、国内国际双循环与经济高质量发展

Digital New Quality Productivity,Domestic and International Circulation and High-quality Economic Development

数字新质生产力作为生产力创新变革新范式,是推动经济高质量发展的关键力量。文章基于2012—2022年我国30个省份的面板数据,利用固定效应模型和中介效应模型,检验数字新质生产力与经济高质量发展之间的关系。研究结果表明:数字新质生产力能够显著促进经济高质量发展;数字新质生产力能够通过促进国内经济循环和国际经济循环来驱动经济高质量发展;数字新质生产力对经济高质量发展的影响存在异质性,具体表现为数字新质生产力在东部地区对经济高质量发展的影响更为显著。加快发展数字新质生产力,夯实经济高质量发展基础,着力构建双循环新发展格局,畅通数字新质生产力赋能渠道,健全地区协调发展机制,因地制宜发挥数字新质生产力效能有助于推动经济高质量发展。

Digital new quality productivity,as a new paradigm for productivity innovation and transformation,is a key force in promoting high-quality economic development.Based on the panel data of 30 provinces in China from 2012 to 2022,this paper uses fixed effect model and mediation effect model to test the relationship between digital new quality productivity and high-quali-ty economic development.The results go as below:Digital new quality productivity can significantly promote high-quality econom-ic development.Digital new quality productivity can drive high-quality economic development by promoting domestic and interna-tional economic circulation.The impact of digital new quality productivity on high-quality economic development is heteroge-neous,and specifically,the impact of digital new quality productivity is more significant in the eastern region.Accelerating the de-velopment of digital new quality productivity,consolidating the foundation for high-quality economic development,focusing on building a new dual-cycle development pattern,unblocking channels for empowering digital new quality productivity,improving the mechanism for coordinated regional development,and leveraging the effectiveness of digital new quality productivity in light of local conditions will help promote high-quality economic development.
