基于比较优势下的吉林省主要粮食作物种植结构调整研究

Study on Structural Adjustment of Main Grain Crops in Jilin Province Based on Comparative Ad⁃vantage

吉林省种植业以粮食作物为主,2018年水稻、玉米、大豆3种粮食作物种植面积占所有农作物种植面积的87.99%,其中仅玉米就占了69.59%,经济作物所占比重较小。该文通过测算2014—2018年吉林省东、中、西各区域主要农作物的平均规模优势指数、效率优势指数和综合优势指数,分析玉米、水稻及大豆3种粮食作物在吉林省东、中、西部的比较优势差异,进而提出吉林省主要粮食作物种植结构的调整方向。

In 2018,the proportion of rice,corn and soybean crops accounted for 87.99%of all crops,of which corn accounted for 69.59%of the sowing area,and cash crops accounted for a small proportion of crops in Jilin Province.By measuring the average scale advantage index,efficiency advantage index and comprehensive advantage index of the main crops in the east,middle and west regions of Jilin Province from 2014 to 2018,this paper analyzes the com⁃parative advantage of three kinds of grain crops:corn,rice and soybean,thus put forward the main food crop planting structure adjustment direction of Jilin province.
