Food security encompasses the safety of the environment for food production, ecological safety, food quality safety, as well as the economic or supply security of food. Generally, society is more concerned with the security of food supply. For the nation, the government's primary policy goals focus on food availability, which includes factors such as food production, international trade capacity, and food reserves. To alleviate concerns about food security, particularly regarding food production and supply guarantees, the national food security guarantee policies can be understood from two perspectives: the provincial governor responsibility system for food security and the full industrial chain guarantee.
