Analvsis of Comparative Advantage of Main Food Crops in Shaanxi Province
摘要
Abstract
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.关键词
