The effects of 14 factors on food production in Huang-Huai-Hai Plain are analyzed by path analysis in this paper, and then the linear regression models of them are established by SPSS software. The results show that electricity consumption for agriculture, growing area of crops, the affected area, annual average temperature and arable land area at the end of the year have great effects on food production. Finally some recommendations are put forward to improve the food production in Huang-Huai-Hai Plain such as improving the level of agricultural mechanization, stabilizing food production, preventing natural disasters and increasing the effective irrigation area.
