An Efficiency Research Of Agricultural Carbon Emissions In The Western Region Under The Background Of Low Carbon

With the global climate change, environmental pollution problem has become increasingly prominent, the world’s attention focus falls on the energy conservation and emissions reduction, so agricultural carbon reduction has become another attention focus after Industrial carbon emissions. Because our country is currently in a critical period of agricultural economic transformation, it should put the low carbon agriculture, green agriculture as the prerequisite of the development and the foothold to achieve the healthy and sustainable development of agriculture. As the key area of agricultural production in China, especially grassland animal husbandry, the western region’s ecological status is very important but also very fragile, it’s particularly important to explore how to achieve its fast economic growth of agriculture on the premise of low carbon. The Paper applies SBM directional distance function to calculate the efficiency of western region agricultural carbon emissions in 2000-2014, then measures total factor productivity in agriculture carbon emissions by utilizing Luenberger productivity indicators, and finally we use Tobit model to analyze the influence factors of efficiency of agricultural carbon emissions. The main conclusions are as follows:The invalid rate of western region agricultural carbon emissions over the period 2000-2014 is 0.3768, inefficiencies in agricultural production are mainly from the inefficiency of labor inputs and agricultural carbon emissions. Agricultural carbon efficiency is different among provinces, only the efficiency of Inner Mongolia and Sichuan is 1. The cause of low efficiency of various provinces is also different. The growth of agricultural carbon emissions total factor productivity(TFP) in the western region is 3.7% over the period 2000-2014, mainly because of the pure technological progress and technology of scale change. From period of time to analyze, the TFP has a slow growth between 2000 and 2007, of which appeared a negative growth in 2004-2007, and increases year by year of 2007-2014. Government’s fiscal expenditure on agriculture, industrial structure and degree of crops damage exist a significant negative impact on agricultural carbon efficiency; the improvement of Labor education level and rural electricity consumption helps to enhance the efficiency of agricultural carbon emissions.
