摘要
在新发展格局下,数字经济已成为推动中国高质量发展的重要引擎。本文通过分析数字经济、制造业集聚与碳生产率之间的作用关系及传导机制,结合2011-2019年省级层面数据实证检验了数字经济对碳生产率的影响。研究发现:(1)数字经济发展对碳生产率的提升具有显著的正向作用,且这一结论在一系列稳健性检验后仍然成立。(2)技术创新、资源配置效率与产业结构升级对数字经济与碳生产率之间的正向关系具有中介传导作用。(3)数字经济对碳生产率的正向作用存在空间溢出效应。(4)制造业集聚对数字经济与碳生产率之间的正向关系存在非线性调节作用,即当制造业集聚水平低于门槛值时,有利于增强数字经济对碳生产率的正向作用;当制造业集聚水平高于门槛值时,则会削减数字经济对碳生产率的正向作用。本文研究结论为我国经济低碳发展提供了一定参考。
Under the new development pattern,digital economy has become an important engine for China to promote green and high-quality development.This paper analyzes the relationship and transmission mechanism among the digital economy,manufacturing agglomeration and carbon productivity,and combines 2011-2019 macro provincial level data examines the impact of the digital economy and manufacturing agglomeration on carbon productivity.The research found that:(1)The development of digital economy has a significant positive effect on the improvement of carbon productivity,and this conclusion is still valid after a series of robustness tests.(2)Technological innovation,resource allocation efficiency and upgrading of industrial structure have a mediating effect on the positive relationship between digital economy and carbon productivity.(3)The carbon productivity is significantly prompted by digital economy,which also has a spatial spillover effect.(4)Manufacturing agglomeration has a nonlinear adjustment effect on the positive relationship between the digital economy and carbon productivity,that is,when the level of manufacturing agglomeration is lower than the threshold value,it is conducive to enhancing the positive effect of the digital economy on carbon productivity;When the level of manufacturing agglomeration is higher than the threshold,its effect is opposite.The conclusion of this paper provides a reference for the development of low-carbon economy in China.
