Analysis On The Efficiency Of Agricultural Characteristics Of Plateau In Yunnan Province Based On Stage DEA Model

In this paper, as a traditional agricultural province, Yunnan province should improve the economic competitiveness of the province, and the development of agriculture has become the basis of economic development in Yunnan province..2011 to seize the agricultural structure adjustment, promote Yunnan Province from traditional agriculture to modern agriculture transformation of the critical period, the Yunnan provincial government put forward "vigorously develop agriculture of Yunnan plateau characteristics, started the agriculture in Yunnan Province" four cards, six characteristic industry base ". Only by relying on its unique resources, climate features and developing features of its own characteristics, Yunnan province can accelerate the transformation of agriculture.This paper uses the stage DEA model to analyze and evaluate the agricultural efficiency of the 2004-2013 in Yunnan Province, and the results show that the agricultural efficiency of the ten years of Yunnan province is of the increase but the efficiency is not high.. In order to analyze the impact of the comprehensive efficiency of Yunnan plateau characteristics exogenous factors, based on this, this paper selected exogenous environmental variables, the Tobit model, the 2004-2013 plateau of Yunnan Province characteristic agriculture efficiency and environmental factors do regression analysis. According to the regression analysis of the income coefficient absolute value is used to sort the exogenous factors.On the one hand, from the input, output angle using DEA model to measure the 2004-2013 Yunnan Province the comprehensive agricultural production efficiency, pure technical efficiency and scale efficiency. The result shows that Yunnan Plateau characteristic agriculture achieves the DEA effective in 2013.2004-2013 ten years in Yunnan Plateau characteristic agricultural efficiency overall level is not high, due to the Yunnan Province agriculture pure technical efficiency of ten years was close to 1, the scale efficiency become main restricting the comprehensive efficiency of agriculture in Yunnan Province plateau characteristics factors. On the other hand, the influence of external environmental factors on characteristic agriculture in the highlands of Yunnan Province the comprehensive efficiency of each are not identical, the per capita net income of rural households in which increase help to improve production efficiency and urbanization level, fiscal expenditure for agriculture, crop the total area affected are comprehensive efficiency of the agricultural industry have negative effects.
