Many scholars have conducted empirical studies on the influencing factors of planting area of main grains. In order to comprehensively analyze the existing research results and explore the root cause of the change of planting area of main grains, this paper uses meta-analysis method to study the influencing factors of planting area change of main grains. The results show that factors such as farmer's education level, agricultural labor force, mechanization level, grain subsidy policy and grain purchase and storage policy have a significant and stable promoting effect on the planting area of main grains while factors such as farmer's age and urban-rural income gap a significant inhibiting effect. In addition, the effects of some influencing factors on the planting area of main grains will change with the passage of time, and the different characteristics of literature researches may also lead to differences in the final empirical results. Therefore, government departments should currently pay attention to the influence of afforementioned variables when expanding planting area of main grains so as to improve the scientific and accurate decision-making. Meanwhile, the follow-up relevant studies in this field should also further improve existing research methods and design., authors=LI Rongqiang¹, CHEN Xuan^1,2, SHI Longzhong¹, authorsList=LI Rongqiang, CHEN Xuan, SHI Longzhong, authorCompany=1.
