Abstract: Along with China taking the strategy of developing potato as a stable food, potatos role in assuring Chinas food security has been continuously upgraded. This paper analyzed the regional distribution features and comparative advantages of potato using the comprehensive comparative advantage index method and grey system prediction model. The results indicated that northwest and southwest regions were the regions with comprehensive comparative advantages for potato production in China, and potato mainly grew in northwest, southwest and northeast regions, but the production center was gradually transferred from northwest and northeast to southwest region. And each region had formed its own unique cultivation pattern. The comprehensive comparative advantage of potato production in northwest, northeast and southwest regions were rather high. Using GM (1.1) model, the advantage areas for potato production was predicted to be further concentrated to northwest and southwest regions, and the number of potato production region with comparative advantage in China would be increased within the coming 10 years.

Key words: potato, major producing areas, comparative advantage, developing tendency
