Studies On The Efficiency Of Agricultural Input-Output In Gansu Province Based On DEA

In this paper, according to scientific, comparable, representative and data easily acquired, such as selection principles of index system, in reference to domestic and foreign scholars research, on the basis of considering the agricultural input and agricultural output in Gansu province in 2001-2013 of the actual situation, selected the seven agricultural inputs, three agricultural outputs. Input indicators for the total sown area of crops, effective irrigation area of agriculture and animal husbandry fishery practitioners, finance support agriculture, total power of agricultural machinery, rural electricity consumption, agricultural fertilizer surueyed,agricultural output indicators for food crop production, fishing output value of agriculture and forestry, agriculture, forestry and fishing added value., then use data envelopment analysis(data envelopment analysis(DEA) method for the evaluation of Gansu province in 2001-2013(Fifteenth Plan, the 11 th Five-Year Plan, the 12 th Five-Year Plan), the efficiency of agricultural input and output, designed to help in Gansu province during the 12 th Five-Year Plan, the 13 th Five-Year Plan much starker choices-and graver consequences-in the stable and healthy development of agriculture to provide some scientific Suggestions.The results showed that in 2001, 2002, 2003, 2005, 2007, 2008, 2012, 2013, the agricultural input and output efficiency is relatively effective, 8 years in Gansu province full use of the resources, the input and output allocation efficiency to achieve optimal; In 2004, 2006, 2009, 2010 and 2011, this 5 years for the DEA effective, resources not achieve the optimal configuration, there is a certain amount of waste, but the efficiency of the non-DEA years are more than 0.9. So in general, the efficiency of agricultural input and output in Gansu province in the direction of the positive development; But non-DEA efficient year accounted for 38.46% of the total year, the proportion is large, a certain degree of Gansu agricultural input and output are not reasonable, the problem is more serious, especially in labor, capital and technology input redundancy, the agricultural input and output efficiency is low; And the land, labor, capital and technology input redundancy and output deficiency, can be improved by DEA projection analysis, so as to realize the optimal allocation of resources.
