Abstract:

By analyzing the regional changes of peanut production in Henan Province in recent 30 years, this paper reveals the evolution law of peanut production pattern and provides guidance for the development of peanut industry, aiming to promote the regionalization, scale development, standardization and industrialization of peanut production in Henan Province. Utilizing the statistical data of Henan Province from 1990 to 2018, the regional changes and influencing factors of peanut production in Henan Province were analyzed by adopting the production focus, production region concentration, index of efficiency comparative advantage, index of scale comparative advantage and index of integrated comparative advantage and so on. The results showed that peanut production in Henan changed from the initial concentration pattern to dispersion pattern and the production center moved to the southwest with the application of new varieties and new technologies and the improvement of mechanization. The status of traditional peanut production areas gradually declined in central and eastern Henan, while the southern region became more and more important in peanut production in the province. The southern Henan had relatively high production concentration and strong efficiency comparative advantages, scale comparative advantages and integrated comparative advantages. It had become the dominant area of peanut production in the province, and the advantages had been gradually strengthened. Scientific and technological support and policy guidance promoted peanut production in various regions, and led to significant differences among the cities. For example, the advantages of peanut production were gradually increased in southern Henan, slightly developed in western Henan, while weakened in eastern and central Henan step by step.
