摘要
在相关统计数据的基础上,以沂蒙山区主要的农业产业为研究对象,设立需求收入弹性系数、区位商、产值增长率、综合比较优势指数、人均产值系数、增长作用率6项评价指标,通过加权求和模型进行量化评价,再运用灰色聚类法对评价结果进行检验。结果表明:基于加权求和模型得出的沂蒙山区农业产业排序:烟草>稻谷>瓜菜>薯类>花生>小麦>水果>大豆>玉米>棉花;基于灰色聚类法得出农业主导产业为烟草、稻谷种植;优势产业为瓜菜、水果、薯类、花生种植,一般产业为小麦、玉米、大豆、棉花。最后综合得出烟草、稻谷、瓜菜为主导产业,薯类、花生、小麦、水果为优势产业,玉米、大豆、棉花为一般产业。研究结果可为当地政府优化农业产业结构调整提供理论依据。
Based on the relevant statistical data, the main agricultural industries in Yimeng mountainous area were regarded as the research objects, and six evaluation indexes were established, namely the income elastic coefficient of demand, location quo- tient, rate of output-value increase, comprehensive comparative advantage index, per capita output-value coefficient, and increase activity rate. Firstly the weighted sum model was used for the quantitative evaluation. Then the gray clustering method was used to examine the evaluation results. The ranking of agricuhural industries in Yimeng mountainous area obtained by the weighted sum mod- el was tobacco 〉 rice 〉 cucurbits and vegetables 〉 potato 〉 peanut〉 wheat 〉 fruits 〉 soybean 〉 corn 〉 cotton. The resuhs obtained by the gray clustering method indicated that： tobacco planting and rice planting were agricultural leading industries; the plantings of cucurbits and vegetables, fruits, potato, and peanut were agricultural advantage industries ; the plantings of wheat, corn, soybean and cotton were agricultural common industries. Finally, it was comprehensively concluded that ： the plantings of tobacco, rice, and cucurbits and vegetables were leading industries ; the plantings of potato, peanut, wheat and fruits were advantage industries; the plantings of corn, soybean and cotton were common industries.
