主要研究结果
1.水泥工业产能分布梳理：
水泥产能分布集中度较高，呈现突出的空间异质性，如产量最集中的五个省份（广东、江苏、山东、四川、安徽）占全国面积11%，熟料和水泥产量分别占全国的31.0%和32.3%。

2.生态效率评估结果：
大多数地市的熟料生产工序生态效率值介于0.7-0.8之间，水泥生产工序生态效率值介于0.65-0.8之间，表明中国各地市水泥行业绿色水平总体接近。

3.水泥行业生态效率与能耗/排放绝对量关联解析：
中国各地市水泥行业的生态效率与能耗/排放绝对量存在不一致性，莫兰指数分别为0.153与0.045，表明高能耗/排放地区未必为生态效率低的地区，论证了采用生态效率这一综合指标评估绿色生产水平的必要性。

原文摘要
To implement strict environmental targets in China's cement industry into small regions, one should evaluate the city-level eco-efficiency that provides comprehensive instruction. This study establishes a plant-level database with 4000+ production lines located in 341 cities, calculates the energy consumption and CO2, SO2, NOx, and PM emissions, evaluates the eco-efficiency in each city via Slacks-based Measure, and verifies the spatial features of these indicators. Results show that the energy consumption and emissions of the industry are highly concentrated, with ~10 % of the land area contributing to 28.4 %–34.6 % of the total amounts in 2019. The average eco-efficiency value of the clinker calcination and cement grinding processes are 0.761 and 0.714, but the city clusters having low eco-efficiency values are inconsistent with the ones having large energy consumption and emission amounts. The results can contribute to the implementation of the targets such as carbon peaking and pollution cap in China's cement industry.

主要研究结果
1.中国热电行业生产及碳排放现状解析：
热点行业碳排放呈现较高的空间聚集性，排放量前五的省级行政区（山东、内蒙古、江苏、广东与山西）占全行业排放38.9%。

2.中国热电行业实现碳达峰目标的预期时间：
基于研究提出的热电行业减排路线预测各地市达峰时间，发现298个地市中有130个地市的热点行业预计在2025年前实现碳达峰、74个地市在2025-2030年间实现达峰，有94个地市有在2030年无法达峰的可能。需基于各地市热电行业实际情况制定差异化的碳达峰目标。

3.中国热电行业实现碳达峰目标的协同效益评估：
中国热电行业2020-2035年间的能耗水平受产能持续增加影响会进一步增加，节能净效益为负；二氧化硫、氮氧化物和烟粉尘等大气污染排放指标受超低排放改造措施的持续推进影响，预计将在2020-2035年间持续下降，实现减污降碳协同增效。

原文摘要
China’s thermal power sector accounted for 45 % of total carbon emissions. Significant regional discrepancies exist between the plants to reach the carbon peaking target, which was overlooked in current research. This study investigates the regional discrepancies of the thermal power plants towards the carbon peaking target firstly. A thermal power plant database with ∼ 4500 power units in 298 cities to evaluate the emission reduction potential, expected carbon peaking period, and co-benefits. Results show that the carbon emission of the sector will experience a 7.2 % rise between 2019 and 2035, but the emission intensity decline by 27.6 g CO2/kWh. Nearly-one-third of the cities have risks not reaching the carbon peaking target before 2030, while most cities can reduce air pollutant emission. This study reveals the inconsistency between spatial carbon emissions and reduction potential of the thermal power plants and proposes several policy suggestions to the whole sector’s decarbonization.

原文摘要
The linkages between CO2 and air pollutant mitigations in the steel industry, including synergies and trade-offs, have significant spatial heterogeneities. Previous research has only investigated the linkages at the industrial level and overlooked the spatial heterogeneity features, which hinders the precise decision making on mitigation strategies. This study quantifies the linkages between CO2, SO2, NOx, and PM mitigations across cities in China's steel industry. A database of 3689 steel production units is established to calculate the emissions. Then, the linkages of mitigation targets of each city are quantified by setting the tailored mitigation pathways in 2019–2035. The results show that the emissions are highly spatially heterogeneous, as the top five contributing cities account for 27.7–33.2% of the total emissions of China's steel industry, but their emission efficiencies are not necessarily worse than the average. The mitigation pathways cause two-sided relationships, as 138 cities will earn mitigation co-benefits to varying degrees, but other 11 cities show the trade-offs. In addition, the mitigation pathway will lead to the highest economic costs as 51.2 billion CNY/a, bringing heavy economic burdens to some cities. This study enriches the co-mitigation management theory and supports the formulation of spatially differentiated mitigation targets and measures.
