China's food security governance has been evolving in line with the goal of food security.At present,a food production pattern with new type of agricultural operating entities as its core and green production as the means has been gradually formed.Adapting to the changing governance goals through self-innovation,with an increasing number of participating entities and a growing diversity of governance tools,China's grain security governance system can effectively ensure food security.However,to realize the modernization of the food security governance system and capacity,a series of challenges need to be addressed,including the bottleneck of food production due to resource constraints,continuous impact on food security by climate change and international environment,low comparative benefits of food production,the abandonment of cultivated land,persistent non-grain production or non-agricultural use of cultivated land,and lagged application and promotion of agricultural technology.It is necessary to develop smart agriculture to improve resource utilization efficiency,strengthen infrastructure construction to mitigate the impacts of climate change,advance the international cooperation to alleviate pressure on the food system,promote high-standard farmland to improve land productivity,and optimize the agricultural technology promotion system to enhance technological efficiency.
