Identification of Core Grain Producing Area in Jilin Province

按照"基础条件好、生产水平高和粮食调出量多"的总体要求,将吉林省粮食核心产区的分布限定在25个商品粮基地县(县级市)内。运用聚类分析法和DEA-DA判别分析法,对吉林省25个商品粮基地县(县级市)的粮食综合生产能力进行了聚类分组和优劣排序,辨别出8个粮食核心产区并分析了其优势和劣势,提出了政策建议。

The authors limited core grain producing area of Jilin province in 25 grain base counties according to basic conditions, production levels and amount of grain transferred out. After identifying and ranking 25 grain base counties by cluster analysis and DEA - DA method, the authors identified 8 core grain producing areas of Jilin province and analyzed their advantages and disadvantages for grain production. The conclusions can provide decision reference for Jilin province in construction of core grain producing area.
