Abstract: This paper put the carbon emission into the measurement framework of cultivated land use efficiency, and analyzed the regional differences and influencing factors of cultivated land use efficiency of 31 provinces in the mainland of China from 2003 to 2015 employing SBM-Undesirable model, Gini coefficient decomposition model and Tobit model. The results showed that: 1) In general, when considering the carbon emissions, the cultivated land use efficiency of most provinces reduced in different rates. 2) From the result of SBM-Undesirable model, we can see that the cultivated land use efficiency showed a fluctuated upward trend in different scale and had significant regional differences that the average annual cultivated land use efficiency was the highest in the northeastern region and lowest in the central region. 3) The Gini coefficient of cultivated land use efficiency reduced in different ranges in the whole country and in the four major regions, which means the regional gap was narrowed and the reductions of inner-regional difference caused the narrowing of regional gap of cultivated land use efficiency in China. 4) Cultivated land endowment, economic development level, scientific and technological development and government attention are important factors influencing cultivated land use efficiency, but there are differences in the direction and intensity of different factors when dividing sample groups in different ways. 5) To achieve low-carbon, high efficiency of cultivated land use and green development of social economic, we not only need to explore the reduction path and reasonable scale of cultivated land use emission with techniques, but also need to regulate and guide carbon emission by systems and policies.

Key words: carbon emission, China, cultivated land use efficiency, regional differences
