碳捕集、利用与封存技术（CCUS）是实现碳中和不可或缺的技术，该技术成本高昂，因此本文从能源成本角度，以我国30个省级行政区2010-2019年的经济数据为基础，以江苏、河北、甘肃为研究对象，研究采用CCUS对省域碳排放效率与经济效率的影响。结果表明：CCUS的实施使三省的碳排放效率增加；采用CCS实现相同的碳捕集比例，江苏省碳排放效率增幅及经济效率降幅均最大。采用地质利用方法，在270元/tCO2捕集成本下，河北与甘肃的经济效率略有增加，而江苏省的经济效率则略有下降。CCUS的实施对各省碳排放效率和经济效率的影响与各省单位能源成本、GDP和碳排放相关。

Carbon capture, utilization and storage (CCUS) is an indispensable technology for achieving carbon neutrality, which is costly. Therefore, this paper investigates the effects of adopting CCUS on provincial carbon emission efficiency and economic efficiency from the perspective of energy cost, based on economic data of 30 provincial administrative regions in China from 2010 to 2019, with Jiangsu, Hebei and Gansu as the research objects. The results show that the implementation of CCUS increases the carbon emission efficiency of the three provinces; the adoption of CCS to achieve the same carbon capture ratio results in the largest increase of carbon emission efficiency and the largest decrease of economic efficiency in Jiangsu Province. Using the geological utilization method, the economic efficiency of Hebei and Gansu increased slightly while that of Jiangsu province decreased slightly under the cost of capturing 270 Yuan/tCO2. the impact of CCUS implementation on the carbon emission efficiency and economic efficiency of each province was related to the unit energy cost, GDP and carbon emission of each province.
