【摘要】：运用DEA-Malmquist模型考察中国低碳农业生产率并利用Tapio脱钩模型探究农业碳排放与其之间的协调性。结果表明:1)我国农业碳排放总量上升趋势较为明显,但年际间也伴随一定的波动起伏;农业碳排放强度一直处于下降趋势;农用物资、稻田与牲畜养殖所引发的碳排放量均呈上升趋势,其中农用物资碳排放所占比重一直处于上升趋势,而稻田与牲畜养殖的占比均有不同程度降低。2)1993年以来,我国低碳农业生产率增速总体偏慢,年均仅为0.80%,基于其累计值的年际变化可划分为平稳起伏、波动下降和波动上升等3个阶段;从增长源泉看,农业前沿技术进步相比农业技术效率发挥了更为显著的作用。3)我国农业碳排放与低碳农业生产率之间的脱钩类型1993—2002年主要表现为强负脱钩和扩张负脱钩;而2002—2012年则多种脱钩状态共存但以弱脱钩为主。
[Abstract]:The DEA-Malmquist model is used to investigate the productivity of low-carbon agriculture in China and the Tapio decoupling model is used to study the coordination between the carbon emissions of agriculture and the agricultural carbon emissions. The results show that the total carbon emissions of agriculture in China are increasing obviously. However, there is also a fluctuating trend between years; the intensity of carbon emissions from agriculture has been on a downward trend; the carbon emissions from agricultural materials, rice fields and livestock farming are all on the rise. The proportion of carbon emissions from agricultural materials has been on the rise, while the proportion of paddy fields and livestock farming has decreased to varying degrees.) since 1993, the productivity growth rate of low-carbon agriculture in China has been on the low side. The annual average is only 0.80, and the interannual variation based on its accumulative value can be divided into three stages: steady fluctuation, fluctuation decreasing and fluctuation rising; from the point of view of the source of growth, Compared with agricultural technology efficiency, agricultural frontier technological progress has played a more significant role. 3) the decoupling types between agricultural carbon emissions and low carbon agricultural productivity in China from 1993 to 2002 are mainly strong negative decoupling and expanding negative decoupling; From 2002 to 2012, multiple decoupling states co-existed, but weak decoupling was dominant.
