通过分析近30年河南省花生生产区域性变化，揭示花生生产格局演变规律，为花生产业发展提供指导，促进全省花生生产的区域化、规模化、标准化、产业化发展。利用1990—2018年河南省统计数据，采用生产重心、产地集中度、效率比较优势指数、规模比较优势指数及综合比较优势指数等指标，分析河南省花生生产区域变化及影响因素。随新品种、新技术的应用及机械化程度的提高，花生生产由最初的集中走向分散，且生产重心向西南方向移动。豫中、豫东等传统花生产区在花生主产地市中的地位逐渐下降，而豫南地区在河南省花生生产中重要性越来越大，该地区拥有较高的生产集中度和较强的效率比较优势、规模比较优势及综合比较优势，已成为河南省花生生产优势区域，且优势在逐步增强。科技支撑和政策引导推动了各区域花生的生产，且导致各市发展差异化显著。例如豫南地区优势逐步增强，豫西地区小幅发展，而豫东和豫中的优势逐步减弱。

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.
