摘要
Abstract
Based on the eight indicator data of the Per Capita Annual Living Expenditure of Urban Residents from 31 provinces,cities and autonomous regions of China in 2009,the current consumption of urban residents structure was analyzed using the R statistical software to adopt the principal component analysis. The results showed that recreation, education and cultural services,transportation and communications, household appliances, housing, and food are the main factors affecting the size of changes in consumption, while clothing,medical care,housing, and food are the main factors that affect the changes in consumption structure;the size of consumption of urban residents in provinces and cities is closely related to the level of their economic developments it is quite similar to the adjacent provinces and cities in the consumption structure ; and there are large differences in consumption structure between the mainland and coastal regions.关键词
