Study on China's urban land expansion mechanism is an important way to solve China's urban construction land expansion rate significantly higher than the urban population growth rate. Based on the theoretical framework of the relationship among economic development, population growth, road traffic development and urban land expansion, this paper studied the differences in the driving force of urban land expansion in different areas, different city-size and different city-level in China. The GWR model (geographic weighting regression) was adopted to test the impact of urban economic development level, road traffic development level and urban population on urban land expansion in 286 prefecture-level cities in 2000, 2005, 2010 and 2014. The main results are as follows:① The level of urban economic development, urban population and road traffic development level all had a positive impact on urban space expansion in China, of which road traffic had the most significant impact on urban land expansion and the economic development level affected the urban land expansion the least. ②The impact of urban economic development level on urban land expansion showed a downward trend, and the driving force of urban population had gradually increased. The impact of road traffic development level on urban land expansion first increased and then decreased. ③Great differences can be find that the impact of economic development level, population size and road traffic development level on urban land expansion in different areas, different city-size and different city-level.
