Abstract:

Based on the global nighttime light data, a new method to measure the urban scale is developed and a tworegime spatial Durbin model is built. Taking advantage of the panel data of 160 cities at prefecturelevel and above in China from 2004 to 2013, this paper makes an empirical research on spatial urban expansion competition. According to the result, we can conclude that the positive competition behavior is significant between the cities with expansion in space. The cities with smaller scale release stronger competition signal to the space, which results the race to the top. Urban agglomeration has an inhibiting effect on the spatial expansion competition between cities. Finally, there is no significant difference in competition strength between provincial capitals and above and other ordinary cities. The results are of great significance to improve the urban expansion control policy, to ameliorate the unbalanced pattern of urban expansion and to promote the newtype urbanization.
