为了解西安市工业各行业碳排放的拉动效应和空间分布特征，采用投入产出分析模型核算西安市工业各行业直接和间接碳排放量，依据相关指标以区县为单元将各行业碳排放进行空间分配。结果表明，西安市90％的工业行业间接碳排放量均超过直接碳排放量，工业内部碳排放具有较强的拉动和关联效应；通用、专用设备和电气机械及器材等制造业碳排放拉动能力较强，导致热电生产、供应业，金属冶炼、压延加工业以及石油加工、炼焦业碳排放量较大；西安市工业6大代表性行业碳排放空间分布显示，未央区、户县和雁塔区为重点减排区；西安市工业碳排放的拉动效应大致呈几何级数递减的趋势由城市内部向外部扩散。%To better understand boosting effects and spatial differentiation of carbon emission from various industrial plants in Xi′an, an input⁃output analysis model was used to calculate direct and indirect carbon emissions from the plants. In line with relevant targets with county or district as basic unit, carbon emissions from various plants were distributed spatially a⁃mong counties or districts as unit. It was found that about 90% of the industrial plants had more indirect carbon emission than direct carbon emission and the carbon emission within the sector displayed strong boosting effects and context effects. Carbon emissions from manufacturing industries like general equipment, special purpose equipment and electric equipment and machinery, etc. were higher in boosting effect, leading to increased carbon emissions from the industries, like thermo⁃power production, thermo⁃power supplying, metal smelting, rolling processing, petroleum refining and coke making, etc.. In Xi′an, the spatial distribution of carbon emissions from 6 major representative industries showed that Weiyang, Huxian and Yanta were priority districts for carbon emission reduction.In Xi′an City, the pulling effect of industrial carbon emis⁃sion displayed a decreasing trend in geometrical progression from the innermost of the city to circumference of the city. The findings could serve as reference for policy⁃makers to determine responsibility each industrial sector should undertake for reduction of carbon emission. It is also helpful to the construction of a low⁃carbon city and realization of industrial upgra⁃ding in Xi′an City.
