【摘要】：本文在构建农业经济核算体系时,同时考虑期望产出与碳排放等环境因素的非期望产出,利用方向距离函数及非期望产出影子价格方法,估算1993-2014年中国30个省(市、区)的种植业低碳生产效率及边际减排成本,并采用核密度函数对边际减排成本的区域差异动态趋势进行探究。结果显示:中、东部地区效率水平较高且趋于平稳,位于前沿生产面上,不存在效率损失,而西部地区效率值相对偏低并呈现波动下降趋势,且全国效率平均值在考察期内呈现先波动下降再短期上升趋势;青海、北京、天津、宁夏、上海、海南等地碳排放影子价格较高,表明这些地区的种植业碳减排的经济成本相对较高,且各地区碳排放影子价格时序变化呈现降多增少的特征;从碳减排成本核密度曲线来看,种植业碳减排成本地区差异性在样本考察期内明显缩小,且碳减排成本平均水平在减小。
[Abstract]:In the construction of agricultural economic accounting system, we consider the non-expected output of environmental factors such as expected output and carbon emissions, and use the direction distance function and shadow price method of non-expected output. Estimate the low carbon production efficiency and marginal emission reduction cost of 30 provinces (municipalities and districts) in China from 1993 to 2014. And the kernel density function is used to explore the dynamic trend of regional difference of marginal emission reduction cost. The results show that the eastern region has a higher efficiency level and tends to be stable, which is located on the front line of production, and there is no loss of efficiency. However, the efficiency value of the western region is relatively low and shows a downward trend of fluctuation, and the national average efficiency shows a trend of first fluctuation and then a short-term increase during the investigation period. In Qinghai, Beijing, Tianjin, Ningxia, Shanghai, Hainan and other places, the shadow price of carbon emissions is relatively high, indicating that the economic cost of carbon reduction in these areas is relatively high. And each region carbon emission shadow price time series change presents the reduction more increases the small characteristic; According to the nuclear density curve of carbon abatement cost, the regional difference of carbon abatement cost in planting industry decreased obviously during the sample period, and the average level of carbon abatement cost decreased.

【正文快照】： 一、引言近年来,由温室气体浓度增加引起的全球变暖成为学术界讨论的焦点问题。毋庸置疑,工业部门是温室气体减排的工作重点,而农业部门碳排放总量与日俱增,亦是未来减排工作不容忽视的组成部分。中国是世界上的传统农业大国,其农业碳排放问题早已引起了各界关注。有数据表明,
