Study On The Polycentrism Of The Internal Spatial Structure Of Post-industrial City

With the advent of industrialization and urbanization, as well as the continuous progress of the post-industrial era, under the influence of the national and urban regional development policies, The evolution from monocentric to polycentric pattern of the urban internal spatial structure and functions began to appear in some of China’s developed cities such as Beijing,Shanghai, Guangzhou, Shenzhen, etc.. On the basis of previous studies, this paper attempts to describe and analyze these features and trends, and to reveal the rules and mechanisms of the evolution.Based on the post-industrialization, growth poles, land rent, edge city and employment subcenter theories and other classic theoretical tools, a polycentric urban internal spatial structure model was built to analyze the feature and mechanism of the multi-levels and multifunctional urban system which is consisted by more than one CBD, multiple sub-centers and potential centers and non-centers. Several kinds of location form were also introduced to clarify the connections between CBD and SCBD.Moreover, an empirical analysis of Shenzhen as a case was also presented in the paper. Base on the data of Shenzhen economic size, population density and price level of the real estate and the industrial structure, the number of urban centers and the structure of the urban internal spatial structure were clarified. The study finally indicated that Shenzhen urban internal spatial structure has been following the trend of monocentric to polycentric since the city entered the era of post-industrialization.Accordingly, the relevant domestic cities need to put efficient dynamics and foresight on their development strategies, plans and policies in response to such an tendency towards polycentric urban system during post-industrial era and promoting its healthy development.
