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 as-pects: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.
