World cities are the central cities that have the power of control world economy and act on the distribution of global strategic resources. With the acceleration of economic globalization and information, world cities having a decisive impact on the future economic restructuring, so the research on world cities has gained ever more attention from both domestic and international academic circle. Based on the results of international and national research, this paper makes a thorough theoretical and demonstrated study on the networking model of contemporary world cities.The dissertation can be divided into three parts. The first part is theoretical foundation research, which includes 2 chapters. The Second is theoretical framework, which includes 2 chapters too; the third is demonstration research, which consists of Chapter 5, 6, 7. There are eight chapters in this thesis, as following:1. Review of world city research home and overseas. The author gives an introduction to the basic theory of world city and comments some representative views in detail. Then the essential conception and characteristics of world city have been summarized.2. The basic situation of world city system networking development. Based on the general connotation of economic network, the author analyzes the essential conception and its model of world city network, discusses the basic pattern and evolving trends of world city networking development.3. The theoretical support: the heterogeneous perspective of contemporary world cities networking development. The author retrospect the theories about the dynamic mechanism of world city network, which is summarized as following: (l)new international labor division theory;(2) international region and world city; (S)control I ing-typed resources and world city development;(4)world system theory; (5)spatial interaction theory and so on.4. The theoretical framework: contemporary wor Id city format ion in the space of flows. Based on these theories of the flow space and above analyses, the author discusses the mutual stimulating relationship among the advanced product i on serv i ce, Serv i ce-typed i nformat i on f I ow and wor I d city network. Through analyzing the field situation of information flow, the author also interprets the common laws about the interaction in the space of flows and put forward the models to calculate service value andIVglobal connectivity that can be use to give the world city network and its power a quantitative evaluation. At last, the primary model of world city networking development has been established, which is a multiplayer and multipole mode.5.The corporation level analysis of world city network: the interaction relationship between global service corporation network and world city network. By means of internet investigation to corporations, the author firstly establishes a global database which indicates the branches distribution of 45 global service corporations in 120 cities, then makes use of the frequency diagrams of the corporation branches distribution to verify the relationship between the advanced production service concentration and worldd city networking development. Thi rdly, the author calculates and analyzes the global connectivity of 120 cities to 46 advanced service corporations. Finally, the global linkage model of world city network has been primarily described.6. The regional background analysis of world city networking development. Firstly, the hierarchy of 120 cities in world city system network has been judged according to every cities total service value. Secondly, by comparing one country' s service value "surplus" and"deficit" to the total economy scale (GDP), the author reveals further the essential relationship between the multinational process of the advanced production service and world city formation. Third, as a view of reg i ona I organ i zat i on the author d i scusses three pan-reg i ona I centra I s that take shape in the world city networking development. Through proving the i nteract i on re I at i on
