Food safety has always been a global hot topic. So we establish a food system evaluation model. Based on the GDP data of 140 countries in the past 50 years, we determine the malicious competition factors, science and technology factors, external assistance factors, planting structure factors, food price factors, human factors and food health factors as indicators, and calculate the environmental factors by analytic hierarchy process. The results show that food price factors, environmental factors and malicious competition factors have a greater impact on fairness and sustainable development. Finally, we predict the time of policy implementation based on the time series prediction model and conclude that it will take ten years to complete the implementation.
