| 用弹性系数讨论农业产出对投入资源的敏感性和资源投入的合理性,采用加权TOPSIS法综合多种产出,分析安徽省农业资源利用情况。结果表明:从全省来看,农业综合产出对农药、从业人员和灌溉等资源投入的敏感性较高;2003、2005和2007年的资源投入不尽合理,而2004、2006和2008年的资源投入比较合理。从皖南山区来看,2002、2003、2005和2007年的资源投入不尽合理,2001、2004、2006和2008年的资源投入则比较合理。安徽省农业实践说明,适度减少投入仍有可能提高产出。 |

| Abstract: |
| When the sensitivity of agricultural output to input resources and the rationality of resources’ inputs are discussed using the elasticity coefficient,it is necessary to integrate various outputs.Because in actual agricultural production system,the input resources and the outputs are variable given usually the input data of the specific resource and the corresponding output data might be hardly collected.In order to compare and discuss the relationship between the input of the specific resource and the output the weighted TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method,which has unambiguous geometric meaning and is simple and convenient,is used to integrate the various outputs.Using the elasticity coefficient of the specific resource and the TOPSIS method the states of agriculture resource utilization in Anhui province are discussed.The results indicate that the agricultural integrated output in whole province is highly sensitive to the inputs of the pesticide,the number of agriculture laborer and the effective irrigated area.The inputs of resources were reasonless in 2003,2005 and 2007,but relatively reasonable in 2004,2006 and 2008.In the mountainous area of the South Anhui province the inputs of resources were reasonless in 2002,2003,2005 and 2007,but relatively reasonable in 2001,2004,2006 and 2008.The practice of agriculture production in Anhui province indicated that the integrated output may be also increased by decreasing the inputs of resources. |
