The central urban area of the metropolis is the central economic, political andcultural part of the city, which represents advanced productivity, culture, technologyand life. The construction of international metropolis experience suggests that it hashigh value to build a social economy form that industry is in harmony with societyand natural ecosystems, and that environment is suitable for both commerce anddwelling and has a harmonious development between economy and society. Such asocial economy form is based on the agglomeration of producer services,technological industry and manufacturing high-end segment, and is a combination ofurbanized living and modern industrial development. And technology-based industryis the proper way to adapt to the requirements of industry development pattern.Throughout the shift from traditional industry to city industry both at home andabroad, and the evolution to technology-based industry, to have a detailedexploration is of great practical importance. Technology-based industry is compliedwith the need of the future development. And it mainly focuses on the developmentof science and technology enterprises as the main target of industrial development.There will be a city industry development model with a large number of intellectualproperties, knowledge-intensive, capital-intensive, technology-intensive, high value-added and high rate of return science and technology industry.On the basis of the theory of choice industries of city central urban area, thepaper tries to make an in-depth study of the factors affecting the development ofscience and technology of city industry, including the central city’s shortage of landresources, employment pressure, the deviation from the goal of sustainabledevelopment, etc. There are some problems that should be faced by the central cityarea. Such problems include the industry scale is not big enough, the financingchannels is not smooth, and management is poor, etc. To solve those problems, thispaper will put forward some solutions, the new model such as “enclave economyâ€,the establishing of industrial park, the transformation of production and thecultivation of enterprise incubator mechanism could be used. I hope that through thestudy of these problems, the paper could offer a certain realistic guiding significance to the urban central urban area in the development of science and technologyindustry.After the overall research on science and technology industries, the paper setsTianjin Nankai District as an example to discuss problems that will be faced in itsdevelopment, and then some solutions will be offered. I hope the analysis of specificexamples would give those similar central cities in the development of science andtechnology of urban industry a certain guiding significance. What is more, I alsohope that through the investigation of some policy recommendations, the papercould do some promotion in the development of Tianjin Nankai District. |
