数字经济、资源错配与碳生产率

Digital Economy,Resource Mismatch,and Carbon Productivity

数字经济的蓬勃兴起对经济社会的各个领域都产生了广泛而深远的影响。在提倡高质量发展的当下,研究数字经济能否促进低碳发展尤为关键。基于2013—2020年中国30个省(自治区、直辖市)的研究数据,构建数字经济指标体系,从资源错配角度讨论数字经济对碳生产率的影响及作用机制,并进行稳健性检验和异质性分析。研究结果表明,数字经济对碳生产率具有显著的正向促进作用,且通过了一系列稳健性检验;数字经济可以通过优化资本和劳动要素配置来促进碳生产率;异质性分析发现东部地区数字经济对碳生产率的作用高于中部地区,而西部地区作用不显著。分位数回归结果表明随着碳生产率的提高,数字经济的影响效应呈现递增趋势。

The prosperous digital economy has had a wide and far-reaching impact on every field of the economy and society.At present when high-quality development is the trend,it is particularly critical to study whether the digital economy can promote low-carbon development.Based on the research data of 30 provinces(autonomous regions and municipalities directly under the Central Government)in China from 2013 to 2020,this paper constructs a digital economy indicator system to discuss the impact of digital economy on carbon productivity and its mechanism from the perspective of resource mismatch;it has also conducted robustness tests and heterogeneity analyses.It is found that digital economy has a significant positive effect on carbon productivity,and has passed a series of robustness tests;digital economy can promote carbon productivity by optimizing the allocation of capital and labor factors;Heterogeneity analyses show that the effect of digital economy on carbon productivity in the eastern region is higher than that in the central region,while the effect in the western region is insignificant.Quantile regression results show that with the increase of carbon productivity,the impact of digital economy shows a progressive trend.
