By making comparison between Shanghai and Chongqing, the main reasons for that the urban-rural integration level of the west part of China lags behind that of the east are that the process of urbanization of the west is much slower than that of the east and that big difference of the income and Engle Coefficient between the urban residents and rural residents of the west of China is larger than that of the east. Thus, several countermeasures for the west of China to accelerate urban-rural integration are to largely promote urbanization level, to adjust industry structure, to establish integrated market between the urban and rural areas and so on.
