英文摘要：

Based on the theoretical foundation of urban innovation function and the urban system theory in knowledge economy, this paper examines the Chinese urban innovation pattern, rank system and inter-urban innovation relationships by using the methods of the questionnaire, the interviews, factorial analysis, mathematics model and so on. The study indicates that the Chinese innovation urban system consists of five levels of tower innovation urban system structure headed by Shanghai and Beijing. Generally, the eastern coastal cities have the important positions in the Chinese urban innovation city system, the capital cities of each province and the economically developed cities have been the centers of the regional innovation. The Chinese innovation urban system were driven by factors, such as urban innovational scale, the urban scientific research scale and efficiency, the urban innovation potential and urban innovation environment and so on. By using the number of co-authored papers among the cities to measure interurban innovational relationship, the study shows that Beijing has been in the central positions of the knowledge dissemination and knowledge cooperation innovation, much more knowledge dissemination among high level cities have occurred than that among the low level cities as well as between the low level cities and high level cities, provincial capital cities and the regional central cities with strong economy have played a vital role in knowledge dissemination.
