基于企业投资的京沪深产业辐射特征研究

Research on Industrial Radiation Characteristics of Beijing,Shanghai and Shenzhen Based on Enterprise Investment

城市发展日益凸显集群化特征,中心城市的辐射带动作用是区域乃至全国发展的重要方面。京沪深作为我国三大城市群的核心城市,其产业辐射作用是影响城市群竞争力的关键因素。本文通过对京沪深三地企业投资数据进行对比分析,研究京沪深产业辐射的特征。研究表明京沪深三地产业辐射活跃度和强度都处于上升通道,产业辐射的区域分布凸显国家发展战略和使命,在辐射模式上分别呈现“网”“线”“点”状特征:北京“网”状辐射全国同时兼顾京津冀协同发展,上海“线”状辐射长江经济带同时重点带动长三角区域,深圳单“点”辐射珠三角区域。在产业辐射行业特征上,北京相对均衡,深圳次之,上海最为集中。北京应更加注重对制造业投资的关注,从而为其发达的服务业寻求稳固的发展依托,上海和深圳需要警惕对房地产行业的投资偏好。

Urban development increasingly highlights the characteristics of clustering,and the radiation driving role of central cities is an important aspect of regional and even national development.Beijing,Shanghai and Shenzhen are the core cities of the three major urban agglomerations in China,whose industrial radiation effect is an important factor affecting the competitiveness of urban agglomerations.Through the comparative analysis of the investment data of enterprises from Beijing,Shanghai and Shenzhen,this paper studies the characteristics of industrial radiation of Beijing,Shanghai and Shenzhen.The research shows that the radiation activity and intensity of Beijing,Shanghai and Shenzhen are in the rising channel.The regional distribution of industrial radiation highlights the national development strategy and mission,and presents the characteristics of“network”,“line”and“point”respectively in the radiation mode:Beijing“network”radiates the whole country,taking into account the coordinated development of Beijing,Tianjin and Hebei;Shanghai“line”radiates the Yangtze River economic belt,and focuses on driving the Yangtze River Delta region;Shenzhen single“point”radiates the Pearl River Delta region.In terms of industrial radiation,Beijing is relatively balanced,followed by Shenzhen and Shanghai.Beijing should pay more attention to manufacturing investment,so as to seek a stable development support for its developed service industry.Shanghai and Shenzhen should be alert to the investment preference of real estate industry.
