This paper uses the data from China's comprehensive social survey for 2010 and 2015 to study the changes in household consumption patterns and to decompose the effects of factors affecting changes in household consumption. Between 2010 and 2015, china's per capita household consumption increased by 50.74 percent, with urban areas growing significantly faster than in rural areas. With the improvement of consumption level, the consumption structure changes from basic consumption to development and enjoyment consumption, but consumption inequality has the tendency to expand. The increase of household income level, the miniaturization of family size, the improvement of education level and urbanization are the main factors of the increase of household consumption level, while the influence of aging on the consumption pattern is relatively small. By anticipating the influence trend of family change on consumption change, policies of enlarging domestic demand and Promoting consumption and family policy should be adapted to the law of household transition. It is of positive significance to the healthy development of society and economy.
