Study on Estimation of Agricultural Total Factor Productivity under Carbon Emission Constraints

The estimation of the traditional agricultural total factor productivity rarely balanced resource and environmental constraints. It neglect the negative effect of agricultural economic development on resources and environment. In this paper, the carbon emission constraint is included in the estimation system of agricultural total factor productivity, and the DEA-Malmquist efficiency index with expected and non-expected output is constructed. The empirical analysis of the 11 differences and trends of total factor productivity and decomposition index of agriculture between 2005 and 2014. The results showed that the technological progress under the constraint of carbon emission plays an important role in the growth of agricultural total factor productivity in Jiangxi Province, and technological progress has become the core driving force. In terms of regional conditions, there are some differences in the total factor productivity of agriculture in 11 districts of Jiangxi Province under the constraint of carbon emission. Some of them are located in the state of discordance development of agricultural production and resources.
