数字经济、高技术产业集聚与碳生产率
Digital Economy,High-tech Industry Agglomeration and Carbon Productivity
摘要
Abstract
Based on the panel data of 30 provinces in China from 2011 to 2023,this paper empirically analyzes the direct ef-fect and indirect transmission effect of digital economy on carbon productivity.The research results show that digital economy plays a significant role in promoting the improvement of carbon productivity,and that this conclusion still holds true after a series of robustness tests.The mechanism test results show that high-tech industry agglomeration plays an intermediary effect in the pro-cess of promoting the improvement of carbon productivity through digital economy.Heterogeneity test results show that the positive effect of digital economy on carbon productivity is the most significant in the eastern region,and decreases successively in the cen-tral,northeast and western regions.The threshold effect test results show that the positive effect of digital economy on carbon pro-ductivity exhibits a non-linear marginal increasing characteristic.关键词
