【摘要】：在构建苹果碳排放测算体系基础上,核算1994—2013年中国21省苹果碳排放量,比较分析不同年份、区域之间苹果碳排放总量与密度,之后采用Malmquist-Luenberger生产率指数(ML指数)分析碳排放约束下中国苹果全要素生产率及其分解成分。结果表明:1)2013年中国苹果碳排放总量为153.20万t,较1994年增加40.22%,呈现出"上升-下降-上升"阶段性变化特征;苹果碳排放密度从1994年1.81kg/hm2持续增长到2013年3.00kg/hm2,增速明显。从区域来看,样本期内中国苹果碳排放总量排名前7位的地区均为苹果主产省,但省域差异明显;不同省域的苹果碳排放密度均逐年增长,但排名前3位的地区保持不变,包括天津、北京与新疆。2)1994—2013年碳排放约束下苹果碳排放平均绩效呈现出阶段性变化特征,年平均增长率为2.98%,其中技术效率增长为0.91%,技术进步率增长为2.61%,说明技术进步的贡献相对较高。从区域来看,黄土高原优势区ML指数、技术进步率指数均高于环渤海湾地区,同时黄土高原优势区苹果全要素生产率的最佳实践者的省份数量也多于环渤海湾优势区。
[Abstract]:Based on the construction of apple carbon emission measurement system, the total amount and density of apple carbon emissions in 21 provinces of China from 1994 to 2013 were compared and analyzed in different years and regions. Then the Malmquist-Luenberger productivity index (ML) was used to analyze the total factor productivity and its decomposition components of Chinese apple under carbon emission constraint. The results showed that the total carbon emission of Chinese apple was one million five hundred and thirty-two thousand tons in 2013, which was 40.22% higher than 1994, showing an "increase". -falling-rising 'phase change characteristics; The carbon emission density of apple continued to increase from 1.81 kg / hm ~ 2 in 1994 to 3.00 kg / hm ~ (-2) in 2013. Apple's carbon emission density increased year by year in different provinces, but remained unchanged in the top three regions, including Tianjin, Beijing and Xinjiang. The average performance of apple carbon emissions showed a periodic change under the constraints of carbon emissions in Beijing and Xinjiang from 1994 to 2013. The average annual growth rate is 2.98, in which the technical efficiency increases to 0.91and the technological progress rate increases to 2.61, indicating that the contribution of technological progress is relatively high. From the regional point of view, the ML index and the technological progress rate index in the dominant region of the Loess Plateau are all higher than those in the Bohai Bay region. At the same time, the number of provinces with the best practitioners of apple total factor productivity in the dominant area of the Loess Plateau is more than that in the dominant area around Bohai Bay.
