RESEARCH ON A KIND OF REGIONAL SPATIAL EVOLUTION STRUCTURE BASED ON SELF-ORGANIZATION
基于自组织理论和新经济地理学，构建了城市与区域空间模型，模拟了单中心和多中心城市在不同条件下的演化特征，并展示了交通条件变化对人口和经济活动从中心向郊区分散的影响。
This paper proposes an urban and regional spatial model based on Self-organization theory and the new production of New Economic Geography. In this model, the agglomeration forces of cities and regions come from the tastes for variety in consumer goods and intermediate-goods besides the local advantages. And the disperse forces come from the competitions of limited land among the agents in the spatial systems. The simulation result indicates that the model can capture the evolution features of monocentric and polycentric cities on different given conditions. And the model can also exhibition the effect of the changing of transport condition on decentralization of population and dispersal of economic activities from the central cities to the suburbs.
