Abstract
Since the adoption of reforming and opening policy, rapid economic growth have taken place in Chinese cities, accompanying the spatial expansion of urbanized area. Such urbanization was caused by the structure of economic growth which depends on the massive input of the production factor like capital and labor. In this study, the TFP (Total Factor Productivity) which represents the technological developmet of cities was estimated using growth accounting analysis. Then the relationship between TFP growth rate and spatial expansion of urbanized area was identified. Results indicated that 1. the extension of urbanized area was relatively small where the cities with high TFP growth; 2. economic growth originated from the extensive input of production factors without technological development might lead the further expansion of urbanized area.
