Abstract:

Nowadays, with the faster and faster pace of regional/global economic integration, cooperation opportunities on all scales have appeared one by one, and the urban agglomerations have been a stronge driving force to promote the persistence and rapid economic development in China. On the other hand, vicious competition between cities poses a threat to the improvement of the integrated competition capability of urban agglomeration. The resource competition between cities is a complex non-linear dynamic process, whose outcome would be influenced by population flow, gaps between per capita income, eco-efficiency and games between governments. It could be found that the resource competition is involved by market force, policies and governmental actions. Based on dynamic modes, the non-linear relationship between urban development and its resource is discussed. And an urban resource competition mode, with a risk-eluded function, is established to simulate the evolution mechanism. The results show: (1) during the process of urban evolution, there is an obvious scale effect, because of which urban areas could develop fast earlier and be held in by resource limitation when the city is oversized; (2) urban resource competition is a very complex dynamic process, with the effect of market economy, governmental action and technological factor. The economy stratagem, population and technological factors would influence the competition result. It helps to construct a harmonious resource relationship in urban agglomeration.

Key words: resource competition, dynamic process, competition mode, risk-eluded function
