摘要：【目的】探究我国薯类作物生产变化规律。【方法】运用规模比较优势指数、效率比较优势指数和综合比较优势指数等方法,对2006-2015年我国薯类作物生产比较优势变化特征进行分析。【结果】结果表明:10年间青海、贵州、重庆和浙江的薯类作物生产规模比较优势指数变化较为突出。上海、天津、吉林和西藏的效率比较优势指数变化较为突出。贵州的综合比较优势指数变化较为突出。【结论】耕地灌溉面积、农民人均纯收入、人均粮食产量与薯类作物生产规模比较优势指数变化、综合比较优势指数变化之间为负相关关系,与效率比较优势指数变化之间为正相关关系。
【Objective】In order to explore the variation of tuber crop production in China.【Method】Comparative advantage change of tuber crop production from2006to2015in China was analyzedbased on the methods of scale comparative advantage index,efficiency comparative advantage index andaggregated comparative advantage index.【Results】The results showed that the prominent increasingregions of scale comparative advantage index were located in Qinghai,Guizhou,Chongqing and Zhejiang.The prominent increasing regions of efficiency comparative advantage index were located in Shanghai,Tianjin,Jilin and Xizang.The prominent increasing region of aggregated comparative advantage indexwas located in Guizhou.【Conclusion】There was a negative correlation relationship between irrigationarea,per capita net income of farmers,per capita output of grain with scale comparative advantageindex change,aggregated comparative advantage indx change.There was a positive correlation relationshipbetween irrigation area,per capita net income of farmers,per capita output of grain with efficiencycomparative advantage index change.
