城市经济圈是以经济比较发达的城市为中心,通过经济幅射和经济吸引,带动周围城市和农村,以形成统一的生产和流通经济网络。它是经济发展的基础,也是城市经济中心作用的场所,法国经济学家弗朗索瓦·佩鲁指出,增长并非同时出现在所有地方,它以不同的强度出现于一些增长点或增长极上,然后通过不同的渠道向外扩散,并对整个经济产生不同的最终影响;其增长发展的势头通过技术、组织、要素、信息等渠道向其周边地区“弥散”,从而使一国经济不是通过平面的板块式推移,而是通过多层次的发展极在不同的点上带动经济的增长。弗朗索瓦的增长点就是我们所指的中心城市,而增长极就是被中心城市幅射和吸引的城市经济圈。以日本为例,日本有三大都市圈,即东京圈、大阪圈和名古屋圈,每个圈都是由一个经济中心城市及其周围若干城市构成的。三大经济圈的面积占 The urban economic circle takes the cities with relatively developed economy as the center and drives the surrounding cities and rural areas through economic radiation and economic attraction so as to form a unified economic network for production and circulation. It is the basis of economic development and the place of urban economic center. Francois Peru, a French economist, pointed out that growth does not occur in all places at the same time. It appears with different intensities on some growth points or growth poles , And then spread outwards through different channels with different ultimate impacts on the economy as a whole. Its momentum of growth and development has been “dispersed” toward the surrounding areas through technologies, organizations, elements and information, so that the economy of a country is not passed However, it is through the multi-level development that the economic growth will be driven at different points. The growth point of Francois is what we call the central city, and the growth pole is the urban economic circle radiated and attracted by the central city. In Japan, for example, there are three major metropolitan areas in Japan: the Tokyo Circle, the Osaka Circle and the Nagoya Circle, each consisting of an economic center city and several surrounding cities. The three major economic circle area accounted for
