Abstract:

As one of the important contents of urban geography, regional urban spatial organization is turning from the traditional city system research to the city networks research. There are two methods to construct city networks. One is using the relational data including the goods flow, capital flow, information flow, population flow among the city to construct city networks; the other one is building models to simulate the relationship between the city, such as interlocking network model and the gravity model. Inspired by the view of the "a spatial dynamic that changes whenever actors move in space" proposed by Menzel, this paper attempts to construct the city networks by using returnees' movement between cities. First, this paper discusses the theoretical relationship between talent mobility and city network. Relational economic geography uses the idea of "based on construction of individual relationship " into network analysis, evolutionary economic geography puts forward the thought of "dynamic proximity", and the research of early uses mobility of talents of high technology to measure the relationship between cities. These had laid a theoretical foundation for the construction of the city network based on the flow of talents movement. Then, we establish the conceptual framework of "triangle model of Chinese returnees". The returnees have the fellow villager's relationship resources in their native places, the classmates' relationship resources in overseas cities and the coworkers' relationship resources in the work city, and these are used in the analysis framework. By integrating the migration data of the returnees, we establish the cities' connections based on the flow of talent, and design a method to calculate the city connectivity. Finally, we select 6 high-end returnees of an innovative team in China to carry out a case analysis. Through the mining of the returnees' city resumes, we successfully construct the city network composed of six talents. As a result, it is suggested that: (1) city innovation network should be examined at national scale under global perspective, and the returnees are good carriers in such researches; (2) the "triangular model" reflects Chinese characteristics, which can explain the formation mechanism of city innovation network better; (3) the returnees team in Beta Pharma Co., Ltd is a typical case that it successfully facilitates inter-city innovation cooperation; and the "triangular model" framework provides a brand-new perspective and analytical method to further research on city innovation network. It should be noted that this paper focuses on theory construction and method exploration, and it needs to use a great quantity returnees' data to carry out systematic research on urban network in the next step, in order to make a greater contribution to urban network theory and the strategy of talents creative practice.
