摘要
为了了解河南省主要农作物的比较优势,以比较优势原理为依据,建立了效率比较优势指数、规模比较优势指数和综合比较优势指数3个指标体系,对河南省主要农作物的比较优势即生产能力进行了分析。结果表明,小麦、花生、烟叶、果用瓜在河南具有极强的比较优势,芝麻、棉花具有较强的比较优势,玉米和蔬菜具有较弱的比较优势,水稻、谷子、高粱、大豆、薯类、油菜籽、糖料则不具备比较优势。因此,建议扩大具有比较优势的小麦等作物的种植面积,压缩没有比较优势的水稻等作物的种植面积。
To know the comparative advantage of main agricultural products in He＇nan Province,based on the principle of comparative advantage,the comparative advantages（production capacity） of the main crops in He＇nan Province are analyzed systematically through finding the index system of efficient comparative advantage index,scale comparative advantage index and integrated comparative advantage index.The results indicate that crops with the highest comparative advantage are wheat,peanut,tobacco leaf and melon,crops with higher comparative advantage are sesam and cotton,and the crops with low comparative advantage are maize and vegetable,and others crops such as rice,millet,sorghum,tuber crops,rape and sugar crops have no comparative advantage.According to the results,it＇s proposed to compress the area of crops with the lower comparative advantage such as rice,enlarge the area of crops with the higher comparative advantage such as wheat.
