摘要
采用投入产出分析法,对2007年辽宁、北京和宁夏3个样本地区出口贸易中隐含CO2排放量进行核算,分析影响出口中隐含CO2排放量的因素,并构建结构分解分析模型来计算各因素对区域排放量差异的贡献值。结果表明,辽宁出口贸易中隐含CO2排放量最高,其次是北京,最后是宁夏。区域出口中隐含CO2排放量受出口总量、出口结构、直接CO2排放强度以及中间生产技术水平等因素的影响。辽宁出口贸易中隐含CO2排放量高于宁夏的原因是其出口总量较大,高于北京的原因在于出口部门中高耗能部门所占比重较高以及直接CO2排放强度较大。调整出口结构、提高能源效率和优化能源结构,是降低区域出口中隐含CO2排放量的主要途径。
The paper, based on cases study on Liaoning, Beijing and Ningxia, evaluates their carbon dioxide emission embodied in exports, analyzes the influencing factors and establishes structural decomposition analysis models to explore the reasons of regional difference of carbon dioxide emission embodied in exports by the input-output analysis method. It is shown that Liaoning ranks top, next by Beijing and then Ningxia. The amount of carbon dioxide emission is limited by export volume, export structure, direct carbon dioxide intensity and technical levels. The amount in Liaoning is more than that in Ningxia because of a larger export volume, and than that in Beijing because of a higher proportion of high- energy consumption and greater carbon dioxide intensity. The primary methods for reducing the amount of carbon dioxide in the atmosphere include adjusting export structure, raising energy efficiency and optimizing energy structure.
