Abstract

Haze pollution is becoming increasingly serious as it endangers human health and pressurizes economic development. This study incorporates the digital economy and haze pollution management into a unified research framework, and uses the panel data of 285 cities in China from 2011 to 2020 to precisely identify the haze reduction effect of the digital economy, governance mechanisms, and the non-linear and spatial spillover characteristics of the haze reduction effect in China. The findings demonstrate that: First, the digital economy can significantly reduce haze pollution, and this conclusion still holds after considering endogeneity and other robustness tests. Second, the digital economy can inhibit haze pollution by promoting industrial upgrading and improving total factor energy efficiency, and there is a chain mechanism of “industrial green transformation → total factor energy efficiency” and “factor market distortion → total factor energy efficiency.” However, the haze reduction mechanism of digital economy is heterogeneous to cities with different levels of economic development. Independent transmission mechanism plays a complete intermediary role in cities with low level of economic development, while it plays a partial intermediary role in cities with high level of economic development. Chain transmission mechanism only has an impact on cities with high level of economic development. Third, there is an evident threshold effect on the digital economy, and its haze reduction effect has N-type non-linear characteristics. Meanwhile, Digital economy has threshold effect on the mechanism of restraining haze pollution through total factor energy efficiency, industrial green transformation and factor market distortion. With the development of total factor energy efficiency, industrial green transformation and the reduction of factor market distortion, the haze reduction effect of digital economy can produce a qualitative leap. Fourth, Haze pollution in the spatial, temporal, and spatial dimensions has spillover and warning effects, and the haze reduction effect of digital economy shows strong positive externalities. Therefore, the digital economy should be actively developed, and industrial green transformation and factor market reform should be promoted to curb haze pollution by promoting industrial upgrading, improving energy efficiency and strengthening regional joint prevention and control mechanisms.

数字经济时代的中国减霾效应
雾霾污染日益严重,既危害人类健康,又给经济发展带来压力。本研究将数字经济与雾霾污染治理纳入统一的研究框架,利用 2011-2020 年中国 285 个城市的面板数据,精准识别中国数字经济的减霾效应、治理机制,以及减霾效应的非线性和空间溢出特征。研究结果表明第一,数字经济能够显著减少雾霾污染,在考虑了内生性和其他稳健性检验后,这一结论仍然成立。其次,数字经济可以通过促进产业升级和提高全要素能源效率来抑制雾霾污染,存在 "产业绿色转型→全要素能源效率 "和 "要素市场扭曲→全要素能源效率 "的链式机制。然而,数字经济的减霾机制对于不同经济发展水平的城市具有异质性。独立传导机制在经济发展水平低的城市起完全中介作用,而在经济发展水平高的城市起部分中介作用。连锁传导机制只对经济发展水平高的城市产生影响。第三,数字经济存在明显的门槛效应,其减霾效应具有 N 型非线性特征。同时,数字经济对通过全要素能效、产业绿色转型和要素市场扭曲抑制雾霾污染的机制具有门槛效应。随着全要素能效的提高、产业绿色转型和要素市场扭曲的减少,数字经济的减霾效果会产生质的飞跃。第四,雾霾污染在时空维度上具有溢出效应和警示效应,数字经济的减霾效应表现出较强的正外部性。因此,应积极发展数字经济,推动产业绿色转型和要素市场改革,通过促进产业升级、提高能效、强化区域联防联控机制等措施遏制雾霾污染。
