Under the impetus of the reforms, Chinese economic situation is grown rapidly, and GDP is also improved significantly. Meanwhile, the expenditure of Chinese residents has increased as well. This research bases on the prices, quantities and expenditure of selected six categories of foods (including “grains”, “vegetables”, “vegetable oil”, “meat and eggs”, “aquatic products” and “other food”) and uses Almost Ideal Demand System (AIDS) Model to establish the food demand system of Chinese urban residents. More, setting the termination of Chinese grain price controlled policy in 1992 as the structural change point to analyze (1) whether the food consumption had structural change; (2) whether the style of food consumption is significantly different by different incomes; and (3) whether the Chinese elasticity of staple expenditure had changed under the increasing income. The research results show (1) the food consumption in Chinese urban areas had significantly structural changes after 1992; (2) the style of food consumption is significantly different by different incomes; and (3) the Chinese elasticity of staple expenditure in low-income households is positive, and middle-income households is negative, and high-income households is positive. As this result, the nature of goods for Chinese staple will be different under different income level.
