摘要
Resource-based cities are the most important players in responding to climate change and achieving low carbon development in China.An analysis of relevant data(such as the energy consumption)showed an inter-city differentiation of CO2 emissions from energy consumption,and suggested an influence of the Industrial Enterprises above Designated Size(IEDS)in resource-based industrial cities at the prefecture level and above in different regions.Then by geographical detector technology,the sizes of each influencing mechanism on CO2 emissions from energy consumption of the IEDS were probed.This analysis showed that significant spatial differences exist for CO2 emissions from energy consumption and revealed several factors which influence the IEDS in resource-based cities.(1)In terms of unit employment,Eastern and Western resource-based cities are above the overall level of all resource-based cities;and only Coal resource-based cities far exceeded the overall level among all of the cities in the analysis.(2)In terms of unit gross industrial output value,the Eastern,Central and Western resources-based cities are all above the overall level for all the cities.Here also,only Coal resource-based cities far exceeded the overall level of all resources-based cities.Economic scale and energy structure are the main factors influencing CO2 emissions from energy consumption of the IEDS in resource-based cities.The factors influencing CO2 emissions in different regions and types of resource-based cities show significant spatial variations,and the degree of influence that any given factor exerts varies among different regions and types of resource-based cities.Therefore,individualized recommendations should be directed to different regions and types of resource-based cities,so that the strategies and measures of industrial low carbon and transformation should vary greatly according to the specific conditions that exist in each city.
资源型城市是我国应对气候变化、实现低碳发展的重要主体。本研究采用各细分能耗数据,测算和分析了不同区域和类型资源型地级城市规模以上工业能耗碳排放及其机理的空间差异,并运用地理探测器技术探究了碳排放的影响机理及各影响因素的影响程度。研究结果表明:资源型城市规模以上工业能耗碳排放及其影响因素均存在显著的空间分异性。从单位就业人数碳排放量来看,东部和西部资源型城市超过资源型城市整体水平,其中煤炭型城市远超整体水平;从单位产值碳排放量来看,东、中、西部资源型城市均超整体水平,其中煤炭型城市远超整体水平;经济规模和能源结构是资源型城市规模以上工业能耗碳排放的主要影响因素;不同区域和类型的资源型城市碳排放影响因素的空间分异较为显著,同一因素对不同区域和类型资源型城市的影响程度也有所不同。因此应针对不同区域和类型的资源型城市,采取因城而异的工业低碳转型对策与措施。
