Under the background of the increasingly obvious"core-periphery"spatial structure,the division of labor in grain producing areas and grain sales regions has been continuously reinforced,which has a profound impact on food security.By using GDP method,the"core-periphery"spatial structure on China's economic map has been investigated and the impact on the inter-regional grain planting acreage,grain output,complementarity of grain production and stability of food security has been analyzed.On this basis,the imbalanced regional responsibility for food security,the limited development of the main grain producing areas,the affected food security of the main grain sales regions,and the abandonment of arable land in major grain producing areas in southern China have been probed.To better ensure food security,a compensation mechanism for grain regional benefit should be established,a bottom line for food self-sufficiency should be set,and the system of provincial governors responsibility for food security in the main grain sales regions and grain balance regions should be improved,from the perspective of the big food viewpoint.
