Abstract

Abstract: In order to have a better understanding of agricultural carbon emission efficiency in China and in east, west and central regions, slack based measure (SBM) under the undesirable outputs is used for measuring the agricultural carbon emission efficiency, where the agricultural carbon emission in 2006 to 2015 in 30 provinces of China is estimated as undesirable output. Then the input-output looseness is used for exploring the reasons for the efficiency difference in different regions and their improvement direction. The results show that the efficiency in east is high and stable, and that in central and west is low. In terms of the whole country, the two indexes with the biggest room for improvement are agricultural capital input and land input. The redundancy rates of agricultural capital input in the three regions are relatively high, while those of land input are high in the central and west regions. This paper aims to provide some references for making rational policies on agricultural carbon emission reduction with regional differentiation and overall coordination.
