Abstract: This paper empirically tests the effects of the urban scale and the urban density on household's transportation expense by utilizing the micro-level data sets from the “China Urban Household Survey”. Results show that both the urban scale and the urban density have positive effects on household's total transportation expense at the national level, but both will raise the ratio of using public transport in daily commuting, which indicates that the spatial feature of China's current urbanization process is relatively eco-friendly. The urban density influences transportation energy consumption only by changing the structure of household's daily commuting modes. However, it will not substantially reduce the commuting distance of households. Currently, eastern areas should put emphasis on the separation of working places and residential sites so as to tackle the problem of increasing commuting distance, whereas western areas should focus on providing more public transportation facilities and networks.
