    Abstract:

    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.
