摘要
以1997-2016年统计数据为依据,运用集中度、综合比较优势、区位熵和显示性对称比较优势指数测算和分析了甘肃省马铃薯省域竞争力。结论表明:全国马铃薯生产集中度排名格局基本形成且保持稳定;我国马铃薯种植区域向西北和西南集聚;各省马铃薯种植的CAI与EAI变动趋势具有相对一致性,马铃薯生产综合优势的"极化效益"提升;甘、贵、渝、蒙、宁、云、陕、川8个省份的马铃薯生产具有较高的专业化水平和较强的市场竞争力;甘肃省马铃薯生产的综合比较优势指数、规模比较优势指数、效率比较优势指数、区位熵均居全国第一,表现出显著的区域优势和强劲的市场竞争力。
Based on 1997-2016 statistics,through the analysis of the concentration ratio,comprehensive comparative advantage,location quotient and revealed symmetrical comparative advantage of potato production in Gansu province,provincial competitiveness of potato in Gansu province were measured and analyzed.Results show that:1)The ranks of concentration ratio basically remained stable.2)China’s potato planting areas are concentrated in northwest and southwest China.3)The trend in changes of CAI and EAI are consistent,and the'polarization benefit'of comprehensive advantages of potato production has improved.4)Potato production in eight provinces of Gansu,Guizhou,Chongqing,Mongolia,Ningxia,Yunnan,Shanxi and Sichuan has a high level of specialization and strong market competitiveness.5)The CAI,SAI,EAI and LQ of potato production in Gansu province rank first in China,showing significant regional advantages and strong market competitiveness.
