Environmental issues represented by haze pollution have become the focus of all sectors of society. Industrial activities, especially industrial energy consumption play an important role in it. After the energy consumption of provincial industrial sectors is decomposed into urban industrial sectors through nighttime light data, this study measures the industrial green total factor energy efficiency (IGTFEE) of Chinese cities from 2003 to 2017, and the haze abatement effect of IGTFEE is investigated from the perspective of spatial correlation. The results show that China's haze pollution and IGTFEE present a positive spatial cluster. Additionally, China's haze pollution has obvious path dependence that shows a monotonous decreasing trend as the aggravation of haze pollution. Meanwhile, although haze pollution shows a serious leakage effect, it plays a warning role in haze control in surrounding areas. This effect is stronger in the most severely polluted areas that have higher economic levels. Not only does the improvement of IGTFEE have a positive effect on local haze abatement but can control haze pollution in spatially related areas through spillover effects and spatial feedback effects. However, the effects are significantly heterogeneous and asymmetric across quantiles, where IGTFEE has a marginal diminishing distribution on haze abatement at the middle and low quantiles, but the haze pollution has intensified at the high quantiles due to the energy rebound effect. The results also reveal that haze abatement conforms to the spatial EKC hypothesis in China. Meanwhile, industrial agglomeration, environmental regulations, and industrial upgrading are vital drivers for haze abatement.
以雾霾污染为代表的环境问题已经成为社会各界关注的焦点。工业活动，特别是工业能源消耗在其中起着重要作用。本研究通过夜间灯光数据将省级工业部门的能源消耗分解为城市工业部门后，测算了 2003 年至 2017 年中国城市的工业绿色全要素能源效率（IGTFEE），并从空间相关性的角度考察了 IGTFEE 的雾霾减排效果。结果表明，中国的雾霾污染和 IGTFEE 呈现出正向空间集聚。此外，中国的雾霾污染具有明显的路径依赖，随着雾霾污染的加剧呈现单调递减趋势。同时，虽然雾霾污染表现出严重的渗漏效应，但在周边地区对雾霾控制起到了警示作用。这种效应在经济水平较高的污染最严重地区更为明显。IGTFEE 的提高不仅对当地的雾霾减排有积极影响，而且可以通过溢出效应和空间反馈效应来控制空间相关地区的雾霾污染。然而，这种影响在分位数之间存在显著的异质性和不对称性，IGTFEE 对中低分位数的雾霾减排有边际递减的分布，但由于能源回弹效应，高分位数的雾霾污染加剧。研究结果还表明，中国的雾霾减排符合空间 EKC 假说。同时，产业集聚、环境规制和产业升级是雾霾减排的重要驱动因素。
