【摘要】：针对传统碳效率评价较多关注经济产出而忽视了福利与人口因素的不足,构建了涉及经济、福利及人口的"全碳效率"评价体系;并针对DEA模型要求评价样本数大于指标数2倍的严格约束,引入主成分分析法进行"全碳效率"评价指标的精简.首先,选取28个关键生产要素作为投入指标,并应用主成分分析法降维为8个合成指标;然后,构建涉及经济产出、福利提升和人口承载三要素的"全碳效率"产出指标;最后,应用DEA-VRS评价模型对我国其中30个省域"全碳效率"进行评价.评价结果显示,主成分分析与DEA相结合的方法用于评价包含指标较多的区域"全碳效率"是有效的;2011年至2014年,广西的"全碳效率"从弱有效提升为有效,天津、河北、湖南和辽宁的"全碳效率"从无效提升为有效,山西、浙江、广东和重庆的"全碳效率"从有效降至无效,而湖北的"全碳效率"没有变化.
[Abstract]:The efficiency of traditional carbon evaluation pays more attention to economic output while ignoring the lack of welfare and population factors, constructs involving economy, welfare and population "carbon efficiency evaluation system; and according to the strict constraint DEA model requires the evaluation of the number of samples is greater than 2 times the number of indicators, based on Principal component analysis of evaluation index of total carbon the efficiency of" streamlining. First, selecting 28 key production factors as input indicators, and using the principal component analysis method for dimensionality reduction of 8 synthetic indicators; then, it involves economic output, welfare and population carrying the three elements of "carbon efficiency" output indicators; finally, the application of DEA-VRS to evaluate the evaluation model of our country among the 30 provinces' total carbon efficiency ". The evaluation results show that the method of principal component analysis combined with DEA for the evaluation index contains more areas" total carbon efficiency "is effective; from 2011 to 2014, Guangxi" The total carbon efficiency increased from weak to effective, and the total carbon efficiency of Tianjin, Hebei, Hunan and Liaoning increased from ineffective to effective. The total carbon efficiency of Shanxi, Zhejiang, Guangdong and Chongqing fell from effective to ineffective, while the total carbon efficiency of Hubei did not change.
