The Measurement Of City Relationship And Analysis Of Network Based On The Main Producer Services

The existence of a city is based on the relation with other cities, the relationshipand interaction between cities forms the original of city relationship.The measurementof simple attribute data of one city itself is the traditional method.The biggestdrawback of this method is that it only tells us the status and rank of one city in theurban system but cann’t show the level relationship,with little or no to clarify therelationship between cities.In order to get the real flow of people,object,capital andinformation, it depends on the relational data.Based on the above analysis,this masterthesis,on the theoretical basis of Castells’"flow space" theory, using the thinking ofTaylor’s world city network modeling ideas,following the relational data miningmethod of globalization and world cities study group, focuses from the perspective ofurban hierarchy to the perspective of urban network to explore the degree andevolution mechanism of networked development and the interaction mechanism ofproducer services in Big Pearl River Delta Urban Agglomeration.In this paper,we collect the scale and level of office network information ofproducer services in Big Pearl River Delta Urban Agglomeration.We mainly makeanalysis from the following aspects:firstly,states urban differentiation and industryfunctional differentiation on the level of main producer services;secondly,makes use of relevant indicators of social network analysis method toanalyze the specific network structure characteristics of the urbanagglomeration;Finally, compares relational data with attribute data by buildingEconometric model and confirms the purpose and original intention of this paper.Theempirical analysis results show that the big pearl river delta urban agglomeration hasobvious network characteristics of the core-edge network structure:guangzhou,shenzhen and Hongkong is the core, other cities is the edge;different types ofproducer services have significant contribution difference to the urban network;On thesame time,"One country, two systems" is the important reason for the transitivityfeatures; it shows different system of contact based on the network connection degreeand GDP or population.Therefore,using relational data will be more reasonable and scientific in the evaluation of complex region and big Urban Agglomeration.On the basis of theoretical research and empirical analysis results, this paperproposes strengthens the construction of distinct level of urban system under theperspective of urban network:Guangzhou, Shenzhen and Hongkong are the center ofthe network to enhance the abilities of diffusion and radiation and try to build upworld cities;Foshan, Dongguan, Zhuhai and Huizhou are the key points to achievesustainable development and make up for the industry defects;Jiangmen, Zhaoqingand Macao are network vulnerabilities to fully exploit their own advantages andactivate the network...
