“涌现成本”及城市规模研究

Researches on Emerging Cost and Urban Size

城市聚集作用引起的"涌现"现象极大的推动了城市及所在地区的发展。本文在分析城市化过程中出现的"涌现"现象的同时进一步分析了城市因"涌现"而付出的代价,即"涌现"成本,其中包括城市基本成本、社会成本及环境成本,并试图寻找在"涌现"效益与"涌现"成本共同影响下的合理城市规模,通过结合对已有理论成果的研究对城市规模与这二者的关系进行分析找出理论上的合理城市规模。最后得出结论并结合我国城市化现状简要提出有助于我国城市化发展的借鉴性意见。

The ＂Emerging＂ phenomenon caused by urban agglomeration effect plays a huge role in promoting the development of the city and region. This paper analyzes the emerging phenomenon during the urbanization process, at the same time analyzes the cost of city because of the emerging phenomenon ： Emerging cost,it includes the city costs, social costs and environmental costs. And try to find the reasonable city size under the effect of both the emerging and emerging cost. Therefore, combined with the existing theoretical results to analysis they relationship with city size and identify a reasonable theoretical size of the cities. At last it concludes and puts forward few brief comments to contribute to the process of urbanization in China with the status of urbanization development in China.
