空间经济集聚理论的兴起与演进

The Rise and Evolution of the Spatial Agglomeration Theory

新经济地理学的空间集聚理论是克鲁格曼、藤田昌久、维纳布尔斯等学者在迪克西特和斯蒂格利茨所创立的D-S模型基础上不断扩展而逐步形成的。其不完全竞争假设对实际情况具有更强的解释力,可以深化我们对空间集聚问题的理解和把握。随着新经济地理学空间经济集聚理论的不断完善和发展,目前该理论已在世界贸易格局、城市形成、产业集聚等经济问题研究中得到了不同程度的实际应用,为解释经济活动的集聚与扩散现象提供了新的视角、理论、方法和工具。

Based on the D-S model,the Spatial Agglomeration theory of New Economic Geography （NEG） is established and developed by Krugman,Fujita and Venables.Its assumption of imperfect competition can help give a clear explanation of the real world and help us fully understand the problems of Spatial Agglomeration.With the improvement and development of the Spatial Agglomeration theory of NEG,this theory is now applied to research on such economic problems as the world trade structure,the formation of the city and the industrial agglomeration.And this helps provide the new angles,theories,methods and tools for us to explain the agglomeration and spread of economic activities.
