Study On The Industry Spatial Differentiation And Its Influencing Factors Of Tokyo Urban Agglomeration

As one of the organizational forms of regional economics,urban agglomeration has become the priority strategy for the whole world.Five of them---Tokyo,Chicago,New York,London and Paris have achieved great developments.Yangtze River Delta,Pearl River Delta and Beijing-Tianjin-Hebei Region are the three most well-developed urban agglomerations in China.Although they have accumulated certain developing experience and have formed some cooperative mechanisms,there are still in lack of efficient cooperation and factor mobility between cities inside them.That's why our constructions on urban agglomeration are faced with serious low-efficiency problems,such as poor coordination in overall economic development,low-level industrial structure and homogeneity in industrial structure,etc.NEG is widely taken as an important theoretical basis when studying the spatial location of economic activities or agglomerations.It attributes the industry spatial distribution to two opposite acting forces,centripetal force and centrifugal force.The former includes externality,market potential,decreasing transport cost and human capital,etc.The latter mainly consists of factor cost and agglomeration cost,etc.Using premiums between wage and rent,the RR spatial equilibrium theorem provides a more simplified way to explain the phenomenon of industry agglomeration and diffusion.Under the guidance of above theories,this thesis takes Tokyo Urban Agglomeration as research subject.Based on statistic data from 1955 to 2013 and focusing on the five most representative industries---manufacture,sales,finance&insurance,real-estate and transport&communication,this thesis first analyzes the industry's spatial differentiation from two perspectives.And then,it conducts empirical study on the influencing factors of manufacture industry agglomeration,such as city size,land price,market potential and transport level.Especially,from the perspective of industry life circle,this thesis innovates on the hypothesis of the relationship between city size and manufacture industry agglomeration.Empirical results suggest the inverted “U” shape relationship between city size and manufacture industry agglomeration,moreover,manufacture industry agglomeration can be negatively influenced by land price and be positively influenced by market potential as well as transport level.Finally,combing empirical results analysis and Japanese government practice,this thesis proposes some suggestions on the construction of our domestic urban agglomerations.
