Abstract
The paper analyzes influencing factors of the world food price by using the data from 1964 to 2013. There is cointegration relationship between the world food price, world agricultural productivity, world food production, food consumption, food inventory, world oil prices, and the exchange rate of dollar. The world agricultural productivity, world food production and the exchange rate of dollar have significantly negative effect on the world food price. The world food consumption has significantly positive impact on the word food price. The impact of the world food stock and the world crude oil price on world food prices is not statistically significant. The elasticity of world food production on the world food price is less than the elasticity of world food consumption. To improve the agricultural productivity, increase food production is the key measure to stabilize the world food prices.
