摘　　要：本文基于2010—2023年我国30个省(区、市)夜间灯光数据,采用面板固定效应模型、中介效应模型和空间杜宾模型实证分析了新质生产力对经济增长的影响效应与作用机制。研究发现:第一,新质生产力能够为经济增长提供新动能;第二,从作用机制来看,新质生产力通过提高技术创新水平、产业集聚水平和人力资本质量为经济增长注入新动力和新活力;第三,新质生产力对经济增长有显著的空间溢出效应,新质生产力的发展能够消除区域和时空的限制,带动更大范围经济增长;第四,异质性分析表明,新质生产力对经济增长的作用效果会因地理区域差异和经济发达程度的不同而产生异质性。研究结论有助于进一步发挥新质生产力作用,为我国经济高质量发展提供理论支撑和实践指导。With the acceleration of the scientific and technological revolution and industrial change,the new-quality productivity,as a representative of the contemporary advanced productivity,is gradually becoming a key factor in promoting economic growth.Based on the nighttime light data of 30 provinces(autonomous regions and municipalities)in China from 2010 to 2023,this paper empirically analyses the effect and mechanism of new-quality productivity on economic growth using the panel fixed-effects model,the mediation effect model and the spatial Durbin model.The study finds that firstly,new-quality productivity can provide new momentum for economic growth;Secondly,in terms of the mechanism of action,new-quality productivity injects new power and new vitality into economic growth by improving the level of technological innovation,the level of industrial agglomeration and the quality of human capital;Thirdly,new-quality productivity has a significant spatial spillover effect on economic growth,and the development of new-quality productivity can remove regional and spatial and temporal constraints and drive economic growth in a wider region;Fourth,heterogeneity analyses show that the effect of new-quality productivity on economic growth can be heterogeneous depending on geographic regional differences and the degree of economic sophistication.The conclusions of the study will help to further develop the role of new-quality productivity and provide theoretical support and practical guidance for the high-quality development of China’s economy.
