中国大麦生产布局及其比较优势探析

Layout of Barley Production and Its Comparative Advantage in China

在对1997—2015年中国大麦生产布局进行分析的基础上,进一步利用产地集中度系数、资源禀赋指数和综合比较优势指数对中国大麦生产布局及其比较优势进行了研究。1997年以来中国大麦主产区变化不大,大麦种植分布总体上呈现逐渐向江苏、云南、甘肃、内蒙古等省份集中的变化趋势,大麦产地分布趋于集中;甘肃、云南、江苏、内蒙古和新疆的大麦生产均具有较为显著的资源禀赋优势和综合比较优势,是中国大麦优势产区,表明中国大麦生产布局变动符合比较优势原则。鉴于江苏、云南、甘肃、内蒙古四省(自治区)具有的大麦种植优势,长期来看,预计其大麦种植面积及产量会继续保持稳定。

Based on the analysis of the layout of China＇s barley production from 1997 to 2015, the layout of China＇s barley production and its comparative advantage were studied further using origin concentration coefficient, resource endowment index and comprehensive comparative advantage index. The results showed that the main barley production areas have changed a little since 1997, as a whole, barley-growing areas showed particular changing tendency that mainly concentrated in Jiangsu, Yunnan, Gansu and Inner Mongolia, and the concentration of barley production areas got higher and higher; Gansu, Yunnan, Jiangsu, Inner Mongolia and Xinjiang were the advantageous areas of barley production in China and all of which had distinct resource endowment advantages and comprehensive comparative advantages in barley production, which meant that the change of the layout of China＇s barley production was in line with the principle of comparative advantages. In view of the advantages of barley planting of Jiangsu, Yunnan, Gansu and Inner Mongolia, their areas and yield of barley will remain stable in the long term.
