新质生产力与碳生产率:效应与机制

New Quality Productive Forces and Carbon Productivity:Effect and Mechanism

选取2013—2022年中国30个省级面板数据,探究新质生产力对碳生产率的影响。研究发现:第一,新质生产力发展对碳生产率的提升具有显著的正向作用,经过一系列稳健性检验和处理内生性问题后结论仍然成立。第二,新质生产力对碳生产率提升的影响存在异质性,分地区来看,中西部地区的碳生产率提高效应相对显著;分维度来看,科技、创新和绿色生产力的碳生产率提高效应存在差异性,具体为绿色生产力>科技生产力>创新生产力。第三,资源错配的降低和产业结构高级化是新质生产力发展引起碳生产率提高的重要机制,经济集聚对新质生产力与碳生产率之间的正向关系存在非线性调节作用。

China's inter-provincial panel data from 2013 to 2022 are selected to study the impact of new quality productivity on car-bon productivity.The study finds that:Firstly,new quality productive forces development has a significant positive effect on carbon prod-uctivity improvement.Secondly,heterogeneity exists in the impact of new quality productive forces on carbon productivity enhancement,and the effect is more obvious in the central and western regions;In terms of sub-dimensions,there is a difference in the carbon produc-tivity-enhancing effect of science and technology,innovation and green productivity,specifically green productivity>science and techno-logy productivity>innovation productivity.Thirdly,reduced resource mismatch and optimization of industrial structure are important me-chanism for increasing carbon productivity due to the development of new quality productive forces.There is a non-linear moderating eff-ect of economic agglomeration on the positive relationship between new quality productive forces and carbon productivity.
