Different countries and regions in the world are experiencing structural transformation of the agri-food system, which is represented by the increase of meat and feed consumption. Based on a detailed review of the global and China's agri-food system transformation, this paper constructs an analytical framework of the impact of agri-food system transformation on food security and discusses the food security issues in China after 2000. The results show that the proportion of the dimension of agri-food system transformation in the food security index has a significant downward trend, and its positive effect on food security is decreasing. At the same time, due to the growth in demand for meat during the transformation of the agri-food system, China imports a large number of feed grains such as soybean and corn, leading to a decline in domestic food self-sufficiency. Furthermore, the coupling coordination degree between China's agri-food system transformation and food quantity security decreases, and their development tends to deviate. In the future, increasing the consumption of grain-saving poultry and curbing table waste are feasible strategies for China to cope with the transformation of agri-food system and ensure food security. China's problems and solutions in facing the transformation of its agri-food system can provide some references for other developing countries.
世界不同国家和地区正在经历农业食品系统的结构转型，其表现为肉类和饲料消费的增加。基于对全球及中国农业食品系统转型的详细审视，本文构建了农业食品系统转型对粮食安全影响的分析框架，并探讨了2000年后中国的粮食安全问题。结果表明，农业食品系统转型维度在粮食安全指数中的占比呈显著下降趋势，其对粮食安全的正向作用在减弱。同时，由于农业食品系统转型过程中肉类需求增长，中国大量进口大豆和玉米等饲料粮，导致国内粮食自给率下降。此外，中国农业食品系统转型与粮食数量安全的耦合协调度降低，二者发展趋于背离。未来，增加节粮型禽肉消费和遏制餐桌浪费是中国应对农业食品系统转型、保障粮食安全的可行策略。中国在面对农业食品系统转型时的问题及解决方案可为其他发展中国家提供一些参考。
