摘要
以重庆市江津区26个镇(街道)为评价单元,从农用地的产出、效率、产投比3方面建立经济效益评价指标体系,运用熵值法确定各个指标权重,采用综合指数法计算2005年江津区及各镇(街道)农用地经济效益评价值。结果表明:江津区农用地利用经济效益水平不高,各镇(街道)间农用地经济效益差异显著。分别依据各镇(街道)农用地产出评价值、效率评价值、产投比评价值和经济效益评价值划分出I,II,III,IV级4个等级层次,并分析了区域差异的原因。
Taking 26 towns in Jiangjin district as the evaluation units,an index system was established from three aspects： agricultural land output index,efficiency index and output-input ratio index.The weight of each index was calculated by the entropy method.The economic efficiency values of agricultural land in 26 towns of 2005 were calculated by the method of comprehensive index.The results show that the economic efficiency of agriculture land was low,and there was significant regional difference in economic efficiency of agriculture land between the 26 towns.According the values of agricultural land output index,efficiency index and output-input ratio index,the whole district was separately divided into Ⅰ,Ⅱ,Ⅲ,Ⅳ grades,the reasons of regional difference was also discussed.
