河南省粮食安全贡献度测算与分析

Calculation and Analysis of the Contribution to Food Security in Henan Province

为客观系统地认识河南省在保障国家粮食安全中的地位和作用,利用2001—2020年的相关宏观数据,使用多角度量化对比分析,从生产角度对河南省粮食安全的绝对贡献度和相对贡献度进行了测算。结果显示:在相对贡献度方面,河南省以一定比例的人口和土地资源生产出了较大比例的粮食,对国家粮食安全起到了重要的贡献作用。但是,其相对贡献度在主要产粮大省中仅居于中等水平,对资源的利用效率方面尚存在改进空间。

In order to objectively and systematically understand the status and role of Henan Province in ensuring national food security,using the relevant macro data from 2001 to 2020,and using multi-angle quantitative comparative analysis,the absolute and relative contributions of Henan Province to food security are calculated from the perspective of production.The results show that in terms of relative contribution,Henan Province produces a large proportion of food with a certain proportion of population and land resources,which plays an important role in national food security.However,its relative contribution is only at the medium level among the major grain-producing provinces,and there is still room for improvement in the efficiency of resource utilization.
