【摘要】：本文根据科学性、可比性、代表性及数据的易获得性等指标体系的选择原则,在参考国内外学者研究的基础上,综合考虑了2001~2013年甘肃省农业投入及农业产出的实际情况,选取了7个农业投入指标、3个农业产出指标。投入指标为农作物总播种面积、农业有效灌溉面积、农林牧渔业从业人员、财政支农、农业机械总动力、农村用电量、农用化肥施用量,产出指标为粮食作物总产量、农林牧渔总产值、农林牧渔增加值。然后运用数据包络分析(data envelopment analysis,DEA)方法评价甘肃省2001~2013年(“十五”、“十一五”、“十二五”)农业投入产出的效率,旨在能为甘肃省“十二五”、“十三五”期间农业的稳定健康发展提供一些科学的建议。结果表明:2001年、2002年、2003年、2005年、2007年、2008年、2012年、2013年这8年甘肃省农业投入产出效率相对有效,资源得到充分利用,投入产出配置效率达到最优;而2004年、2006年、2009年、2010年和2011年这5年为非DEA有效,资源没有达到最优配置,存在一定程度的浪费,但是非DEA有效年份的效率都在0.9以上。因此总体而言,甘肃省农业投入产出的效率向着积极的方向发展;但是非DEA有效的年份占总年份的38.46%,比例比较大,说明甘肃省农业投入产出存在一定程度的不合理,问题比较严重,尤其是劳动力、资金和技术的投入冗余,致使农业投入产出效率的低下;而土地、劳动力、资金及技术的投入冗余和产出不足,可以通过DEA投影分析来改进,从而实现资源的最优配置。
[Abstract]:Based on the principles of scientific, comparable, representative and data availability, this paper makes reference to the research of domestic and foreign scholars. Considering the actual situation of agricultural input and agricultural output in Gansu province from 2001 to 2013, 7 agricultural input indexes and 3 agricultural output indexes are selected. The input index is the total planting area of crops. Agricultural effective irrigation area, agriculture, forestry, animal husbandry and fishery practitioners, financial support for agriculture, total power of agricultural machinery, rural electricity consumption, the amount of agricultural fertilizer, output indicators are the total yield of food crops, total output value of agriculture, forestry, animal husbandry and fishery. The value added of agriculture, forestry, animal husbandry and fishery was added. Then data envelopment analysis was analyzed by data envelopment analysis. Dea was used to evaluate the agricultural input-output efficiency of Gansu Province from 2001 to 2013 ("15", "11th Five-Year Plan", "12th Five-Year Plan"), in order to be the 12th Five-Year Plan of Gansu Province. The steady and healthy development of agriculture during the 13th Five-Year Plan period provides some scientific advice. In 2012 and 2013, the agricultural input-output efficiency of Gansu Province was relatively effective, the resources were fully utilized, and the input-output allocation efficiency reached the optimum. On 2004, 2006, 2009, 2009 and #date-these five years are non-#en0# effective, and the resources are not optimal allocation, there is a certain degree of waste. But the efficiency of non-effective years of DEA is more than 0. 9. Therefore, the efficiency of input and output of agriculture in Gansu Province is developing in a positive direction. But the non-effective year of DEA accounted for 38.46 percent of the total year, indicating that there is a certain degree of unreasonable agricultural input and output in Gansu Province, especially the labor force. The redundancy of input of capital and technology causes the input-output efficiency of agriculture to be low; The input redundancy and output of land, labor, capital and technology can be improved by DEA projection analysis to achieve the optimal allocation of resources.
