河南省作为农业大省、中原粮仓,在全国有着非常重要的战略地位,这个定位要求河南出色地完成农业高质量发展的任务,保证人们不仅吃得饱、更要吃得好。河南省农业的高质量发展是时代和市场的要求,是实现农业发展转折和追求产业协调发展的必由之路,是河南实现经济社会高质量发展的重要推动力。本文根据柯布道格拉斯函数,选取河南省1990~2019年固定资产投资额、第一产业劳动力、农业机械总动力等对河南省第一产业GDP增长相关的数据并分析其原因,对边际产出、边际弹性、边际技术替代率进行了拟合分析,进而对河南省农业发展提出了一些相关的建议。

As a large agricultural province and the granary in the Central Plains, Henan Province has a very important strategic position in China. This positioning requires Henan to fulfill the task of high-quality agricultural development and ensure that people not only have enough food, but also eat well. The high-quality development of agriculture in Henan Province is the requirement of the times and the market. It is the only way to realize the transition of agricultural development and the pursuit of coordinated industrial development. It is an important driving force for Henan to achieve high-quality economic and social development. According to the Cobb Douglas function, this paper selects Henan Province’s fixed assets investment, primary industry labor force, total power of agricultural machinery and other data related to Henan Province’s primary industry GDP growth from 1990 to 2019 and analyzes the reasons. A fitting analysis of the marginal output, marginal elasticity, and marginal technology substitution rate was carried out, and then some relevant suggestions were put forward for the agricultural development of Henan Province.
