【摘要】：通过引入联合生产的理论视角和概念框架,在以往把农业碳排放视为非期望产出基础之上,将农业碳汇作为期望产出纳入碳绩效核算体系,结合2007—2015年中国42个低碳试点省市的面板数据,运用碳计量模型、超效率SBM模型和ML效率指数分析了中国低碳农业发展绩效的时空变化趋势,继而对不同地区低碳农业政策实施效果进行了评价。结果表明:低碳农业发展是一个具有4种产出品的联合生产格局,旨在实现农产品和碳产品之间的耦合关系得以脱钩;在农业生产过程中,低碳试点地区虽然保持了良好的净碳汇效应,但未能实现低碳农业的有效发展,农业投入要素的冗余是主要制约因素;大部分试点地区低碳农业生产效率呈现震荡上升趋势,实现了低碳农业发展的绩效改进,农业技术进步是绩效改进的主要驱动力。整体上来讲,低碳试点省市建设虽然在一定程度上促进了低碳农业的发展,但效果并不明显,主要制约因素源于农业技术效率的降低。
[Abstract]:By introducing the theoretical perspective and conceptual framework of joint production, agricultural carbon emissions were regarded as non-expected outputs in the past, and agricultural carbon sinks were incorporated into the carbon performance accounting system as expected outputs. Based on panel data of 42 low carbon pilot provinces and cities in China from 2007 to 2015, using carbon measurement model, super-efficiency SBM model and ML efficiency index, this paper analyzes the temporal and spatial trends of development performance of low-carbon agriculture in China. Then the effect of low-carbon agriculture policy in different regions was evaluated. The results show that the development of low-carbon agriculture is a joint production pattern with four kinds of outputs, aiming at decoupling the coupling relationship between agricultural products and carbon products. In the process of agricultural production, although the low carbon pilot area maintained a good net carbon sink effect, it failed to achieve the effective development of low-carbon agriculture, and the redundancy of agricultural input elements was the main constraint factor. In most of the pilot areas, the productivity of low-carbon agriculture is on the rise, and the performance improvement of low-carbon agriculture has been realized. Agricultural technology progress is the main driving force of performance improvement. On the whole, although the construction of low-carbon pilot provinces and cities has promoted the development of low-carbon agriculture to a certain extent, the effect is not obvious, and the main restricting factors are the reduction of agricultural technical efficiency.
