Abstract:

The concept for Use Efficiency of Agricultural Resources (UEAR) was reinterpreted in this paper firstly. Then, a new evaluation framework for UEAR was established so as to develop the evaluation theory and method for UEAR. Method of Synthetically Multivariate Equation was adopted to calculate the Use Ratio and Productivity of Agricultural Resources (URPAR), and Data Envelopment Analysis (DEA) to evaluate the Allocation Efficiency of Agricultural Resources (AEAR). This paper can be concluded as: 1) The concept of UEAR includes two parts i.e. URPAR and AEAR. AEAR still can be analyzed as concepts of Pure Technical Efficiency (PTE) and Scale Efficiency (SE). 2) UEAR of Changshu and Taihe is 0.967 and 0.984 respectively, URPAR 0.953 and 0.922, and AEAR 0.684 and 0.733 respectively. 3) The AEAR is lower in Changshu than that in Taihe because the percentage of redundant input for agricultural resources in grain production is higher in Changshu than that in Taihe. The percentage of redundant input for labors, fertilizers and capital in Changshu are 28.36%, 23.45% and 20.48% respectively while those of Taihe are only 8.84%, 8.83% and 10.58% respectively. 4)The evaluation results of URPAR are not always in accordance with AEAR. Therefore, the evaluation of UEAR should consider both the URPAR and AEAR.
