The current global food security situation is still very serious. As an important means of global governance,especially global agriculture and food governance,food security evaluation system has attracted the attention of the international community in recent years. All kinds of international organizations,research institutions and collaborative mechanisms composed of multilateral interest groups have participated in the system,and in-depth analysis will help China better participate in global governance and safeguard national food security. Through analysis of evaluation systems formulated by the governance bodies such as Food and Agriculture Organization of the United Nations,it can be found that elements such as standards setting,data collection and processing,and ranking and classification have formed the deep logic of the system,and reflect that the global governance is still dominated by the west. In China’s long-term policy practice and academic research,a variety of food security evaluation systems have been formulated,but these evaluation systems focus on food production and supply,and pay less attention to the consequences of food issues. Moreover,the evaluation systems developed by the academia have little international influence. In general,it can be found that the effectiveness of food security evaluation has not been fully realized,the new global governance system needs to be established,and the discourse and experience of China and other developing countries should receive more attention in the global governance system.
