The Regional Comparative Advantages of Vegetable Production in Yunnan Province

To clarify the regional comparative advantages of vegetable production is of great significance to the sustainable development of vegetable industry in Yunnan. Based on relevant data of vegetable planting area, yield and agricultural output value in Yunnan from 2001 to 2018, the concentration index, comprehensive comparative advantage index and resource endowment coefficient of vegetable production in 16 prefectures and cities of Yunnan were calculated, to study the regional comparative advantages of vegetable production and explore the planting resource endowment of different vegetable types in different prefectures and cities. The results showed that the vegetable production in Yunnan presented an increasing trend, and the concentration degree was stable. From the regional perspective, the comprehensive comparative advantages of central, western and southern Yunnan were significant. From the perspective of prefectures and cities, the comprehensive comparative advantages of Kunming, Yuxi, Chuxiong, Honghe and Dali were more obvious. From the perspective of main vegetable types, cucurbitaceous vegetables in the whole province had obvious comparative advantages, and leaf vegetables and scallions and garlic in central Yunnan, tubers in northeast Yunnan, cucurbitaceous vegetables and eggplants in southern Yunnan had comparative advantages, and the five major vegetable types all had comparative advantages in Kunming, Honghe, Yuxi, Chuxiong, Zhaotong and Wenshan. To speed up the development of vegetable industry in Yunnan, this paper put forward some countermeasures, such as further optimizing the regional layout of vegetable industry, improving the facilities and equipment of circulation channel, and giving full play to the exemplary role of leading enterprises.
