中文摘要:
      利用生产集中度指数和综合比较优势指数ꎬ从主产区和省域 2 个层面考察了中国马铃薯种植区域比较优势ꎬ进行了 时空演进ꎬ并利用 ArcGIS 软件进行了可视化分析ꎮ 结果表明:第一ꎬ2014—2018 年中国马铃薯 4 大主产区的生产集中度指数 呈波动状态ꎬ综合比较优势从高到低依次是北方一作区、西南混作区、南方冬作区、中原二作区ꎮ 第二ꎬ北方一作区和西南混 作区是马铃薯种植“高规模-高效率”的双高地区ꎬ中原二作区和南方冬作区是马铃薯种植“低规模-高效率”的效率优势区 域ꎮ 第三ꎬ省域马铃薯生产集中指数和综合比较优势指数存在时空差异ꎬ浙江、河北、广东的马铃薯综合比较优势指数值持续 上升ꎬ而黑龙江、辽宁、吉林、湖北、新疆、湖南、西藏、江西和安徽等省份的综合比较优势始终处于较低水平状态ꎮ 关键词:马铃薯ꎻ种植区域比较优势ꎻ时空演进ꎻ生产集中度指数ꎻ综合比较优势指数
英文摘要:
      This paper studies the spatial and temporal evolution of the comparative advantage of potato planting areas from the main praduction area and provincial level in Chinaꎬ based on the production concentration index and comprehensive comparative advantage indexꎬ and the visual analysis was carried out by using ArcGIS software. The results showed that: firstlyꎬ from 2014 to 2018ꎬ the production concentration index of the four major potato producing areas in China fluctua ̄ tedꎬ and the comprehensive comparative advantage from high to low was the first cropping area in the northꎬ the mixed cropping area in the southwestꎬ the winter planting area in the southꎬ and the second cropping area in the Central Plains. Secondꎬ the first cropping area in the north and the mixed cropping area in the southwest are the double high areas of " high scale and high efficiency" ꎬ while the second cropping area in the Central Plains and the winter planting area in the south are the superior areas of " low scale and high efficiency" of potato planting. Thirdlyꎬ there are spatiotemporal differ ̄ ences in provincial potato production concentration index and comprehensive comparative advantage index. The AAI values of Zhejiangꎬ Hebei and Guangdong continue to riseꎬ while the comprehensive comparative advantages of Heilongjiangꎬ Lia oningꎬ Jilinꎬ Hubeiꎬ Xinjiangꎬ Hunanꎬ Tibetꎬ Jiangxi and Anhui are always at a low level.
