摘要
根据比较优势理论,利用改进的综合比较优势指数法,对陕西省小麦、稻谷、玉米3种主要粮食作物在1990~2009年间的比较优势变动趋势进行了分析,其结果表明:3种作物的综合比较优势指数都处于劣势,其中小麦和玉米具有规模优势但是效率和效益指数较低,稻谷具有效率和效益优势但是规模太小,并在此基础上提出了陕西省主要粮食作物结构调整的对策和建议。
According to the comparative advantage theory,by using the improved comprehensive comparative advantage index method,this paper analyzed the changes in the comparative advantage of three main food crops(wheat,rice and maize) in Shaanxi province during 1990~2009.The result showed that the comprehensive comparative advantage indexes of these three crops all were at a disadvantage;wheat and maize had higher scale advantage index(SAI),but their efficiency advantage index(EAI) and benefit advantage index(BAI) were lower;however,rice had higher EAI and BAI,but its SAI was lower.Based on this analysis,some proposals for the structure readjustment of the main food crops in Shaanxi province were put forward.
