Methods: Study take quantitative analysis method, based on research achievements, collect data, estimate the Chinese domestic food production function and food demand function by stepwise regression and linear regression method, obtained 2000 on the basis of--2014 China's domestic food supply and total demand, estimated Chinese food safety standards and the safety of overseas farmland investment on Chinese food. Results: Stepwise regression results showed that the main factors affecting domestic food production capacity of China's grain sown area, grain disaster and the effective irrigation area, the impact of other factors on food production is not significant. Meanwhile, 2000--2014 China's overseas investment in farmland into infancy stage of rapid development and stable development stage; the degree of China's overseas investment in farmland on China gradually increase food security, and within the expected time of impact continued to rise.
