| 摘 要： | 农业生产投入与产出的关系是农业生产效率的刻画方法之一。选择具有代表性的农业生产投入指标,对多个指标进行模糊评价。鉴于指标数据的具体情况,选用偏大型正态分布作为模糊集的隶属函数;考虑指标之间的差异度,利用熵值法确定各指标的权重。通过加权变换得到模糊评价决策向量。利用评价决策向量和各地区农业生产产出情况进行比对,可以得到生产效率的合理刻画。根据实际数据,就黑龙江省各地区的农业生产效率进行了分析。

| Abstract: | The relationship between agricultural production input and output is a depiction method of agricultural production efficiency.This paper selects some representative indices of agricultural production input and fuzzily evaluates various indices.In view of concrete condition of index data,the maximum-inclined normal distribution is selected as membership function of fuzzy sets.Considering difference on various indices,each index weight is determined by entropy method.Fuzzy evaluation decision vector is obtain... |
