中国能源消费碳排放强度下降过程中的省际减排成效数据集(2005-2016)

A Dataset of Provincial Carbon Emissions Reduction Performance in the Process of Carbon Emissions Intensity Reduction in China's Energy Consumption from 2005 to 2016

基于中国30个省市(西藏、港澳台数据暂缺)的能源消费和经济发展数据计算中国碳排放强度及各省份的碳排放强度、产值份额,采用矫正系数衡量各省份的碳减排有效性,根据各省份能源消费碳排放强度及产值份额构建自上而下的全国能源消费碳排强度恒等式,运用LMDI-Ⅰ(Logarithmic Mean Divisia Index)分解方法获取各省份、各省份能源消费碳排放强度及产值份额对全国能源消费碳排放强度下降的贡献率,并按照“碳减排有效性-碳排放强度贡献-省份综合贡献-减排有效性与省份综合贡献关系”的逻辑进行分析。结果显示:中国能源消费碳排放强度整体具有下降特征,与2005年能源消费碳排放强度相比,2016年下降了45%;超过一半的省份为碳减排有效区且数量呈增加趋势,而减排未达标的省份多数为经济欠发达地区,各省份间的碳减排路径存在显著差异;多数省份能源消费碳排放强度的贡献率呈上升趋势,省份差异逐渐缩小;省份碳减排综合贡献的进位赶超势头强劲,绝大多数省份对全国能源消费碳排放强度的下降作出了贡献;碳减排成效良好省份数量最多,中等区多散布于东部沿海地区及少数内陆地区,欠佳区在西部地区空间格局保持相对稳定。该数据集包括:(1)中国能源消费碳排放强度;(2)分省份碳减排矫正系数;(3)中国能源消费碳排放强度下降量分解因素贡献率;(4)省份能源消费碳减排有效性和贡献位序。该数据集存储为.xlsx格式,1个数据文件,数据量为18.8 KB。

Based on the energy consumption and economic development data of 30 Chinese provinces(excluding Tibet,Hong Kong,Macao,and Taiwan),a dataset of China's carbon emissions intensity and provincial output share and carbon emissions intensity in China was built.The correction coefficient was applied to measure carbon emissions reduction effectiveness in each Chinese province.According to the carbon emissions intensity of energy consumption and the output value share of each province,the equation of national carbon emissions intensity in China's energy consumption was established from top to bottom,and the contribution rate of the carbon emissions intensity of energy consumption and the output value share in each province to the decline of national carbon emissions intensity in energy consumption was determined using the LMDl-I method.Following the idea of"emissions reduction effectiveness-carbon emissions intensity contribution-comprehensive contribution by province-relationship between provincial carbon emissions reduction effectiveness and the comprehensive contribution of each province",the performance of carbon emissions reduction of each province in the process of carbon emissions intensity reduction in China's energy consumption was evaluated.The results of the dataset analysis showed that:(1)The carbon emissions intensity of China'energy consumption followed a downward trend,decreasing by more than 45%in 2016 from 2005 levels.(2)More than half of the provinces of China were evaluated as effectiveness areas for carbon emissions reduction,and this number increased during the study period;most of the provinces that did not meet the carbon emissions reduction standards were located in economically underdeveloped areas,and there were significant differences in carbon emissions reduction paths across provinces.(3)The contribution rate of the carbon emissions intensity of energy consumption in most provinces followed an upward trend,and the regional differences gradually decreased.(4)The competing momentum of the comprehensive contribution by provinces was strong,and most provinces contributed to the reduction of the carbon emissions intensity of China's energy consumption.(5)The number of provinces with good carbon emissions reduction performance was the highest;the general areas were scattered in the eastern coastal area and in a few inland areas,while the spatial pattern of the poor areas remained durably in the western region.The dataset built includes the following data:(1)Carbon emissions intensity of energy consumption in China;(2)Correction coefficients of the provincial carbon emissions reduction of energy consumption;(3)Decomposition factors'contribution rate to the reduction of carbon emissions intensity in China;(4)Order of effectiveness and comprehensive contribution of provincial carbon emissions reduction.The dataset consisted in one file in.xlsx format,with a size of 18.8 KB.
