摘要/Abstract

摘要： 当前全球变暖问题日益突出，我国提出“双碳”目标，积极探索经济发展方式的转变，数字经济的迅速发展为我国经济低碳转型带来了新契机。本文基于2011—2019年中国省际面板数据，构建空间计量模型考察数字经济发展的碳减排效应以及异质性环境规制的调节作用。研究发现：数字经济发展在3类空间权重矩阵下均对碳排放强度有着显著的抑制作用，且由于其扩散效应和辐射效应，数字经济发展对碳排放强度还存在负向空间溢出效应，能对周边地区的碳排放起到抑制作用；命令控制型环境规制削弱了数字经济发展的碳减排效应，而在市场激励型、公众参与型环境规制的作用下，数字经济发展的碳减排效应更加显著。在此基础上，以数字经济发展水平和经济增长水平为门槛变量构建面板门槛模型，进一步探究数字经济发展对碳排放的门槛效应。研究发现：数字经济发展对碳排放强度存在基于数字经济发展水平的双重门槛效应以及经济增长水平的单一门槛效应，在两者跨越相应的阈值之后数字经济发展方能有效发挥碳减排效应。在研究结果的基础上，提出如下政策建议：推动传统产业与现代数字技术相结合帮助实体经济提质增效；采用灵活的组合环境规制引导企业主动走绿色发展道路，并加快推动建立绿色数据中心；提高数据中心运营效率，合理有效配置各区域数字经济资源，实现经济高质量发展。

Abstract: As global warming is accelerating, China presents “dual carbon” goal as an attempt to transform China ‘s economic development way, which may be powered by digital economy. This paper uses China ‘s 2011 to 2019 provincial panel data to establish a spatial counting model used to study the carbon emission reduction of digital economy and adjustment of heterogeneous environmental regulations. Digital economy strongly depresses carbon emission intensity under 3 types of spatial weight matrix, and casts a negative spatial overflowing due to its diffusion and radiation, constraining the carbon emission in the surrounding areas. Mandatory environmental regulations play an adverse role on its carbon emission reduction of digital economy, while market-stimulating and public-participating environmental regulations work positively. A panel threshold model is established based on digital economic development level and economic growth level as threshold variables to study the threshold effect of digital economy on carbon emission. Digital economy has a dual threshold effect based on its level and sole threshold effect based on economic growth on carbon emission intensity, and can effectively fulfill carbon reduction over threshold values. This paper puts forward suggestions on combining traditional industries with digital technologies to develop economy, applying flexible combined environmental regulations to lead a green development for industries, speeding up construction of green data center, increasing its operating efficiency, appropriately allocating digital economic resources to reach a quality economic development.

Key words: digital economic development, carbon emission reduction, environmental regulation; spatial Dubin model
