【摘要】 东北三省是我国重要的粮食生产基地，研究东北三省粮食生产的主要影响因素具有重要的意义。为此，基于2007—2021年东北三省的面板数据，运用灰色关联理论对影响东北三省粮食生产的影响因素进行关联分析，量化粮食总产量与主要影响因素的关联度。同时，从土地利用水平、农业现代化水平、经济条件3个方面选取8个指标进行关联分析，研究东北三省粮食生产的主要影响因素。结果显示：不同省份粮食生产的主要影响因素不同，土地利用水平和农业现代化水平对东北三省粮食生产影响较大。最后，为东北三省提高粮食产量提供了政策建议。更多还原

【Abstract】 The three Northeast provinces are important grain production bases in our country. The study on the main influencing factors of grain production in the Three Northeast Provinces has great significance. Based on the panel data of the three northeastern provinces from 2007 to 2021, the grey correlation theory was used to conduct correlation analysis on the influencing factors of grain production in the three northeastern provinces, and the correlation degree between total grain production and the main influencing factors was quantified. In this paper, eight indexes were selected from three aspects: land use level, agricultural modernization level and economic conditions for correlation analysis to study the main influencing factors of grain production in the three northeastern provinces. The results showed that the main influencing factors of grain production were different in different provinces, and the land use level and agricultural modernization level had great influence on grain production in the three northeastern provinces. Finally, it provides policy suggestions for the three northeast provinces to increase grain output.更多还原
