地理区位、城市功能、市场潜力与大都市圈的空间结构和成长动力

Geographical Region, Urban Function, Market Potential and the Spatial Structure and Growth Dynamic of Metropolitan Circles

地理区位差异引发经济活动的空间分异,并决定了城市功能差异性和互补性,而地理区位差异的有限性决定了城市竞争关系的存在,互补与竞争的空间作用构建了大都市圈内既相对稳定又动态优化的层级结构体系,推动大都市圈成长。区域交通格局优化则进一步促进市场潜力扩大和城市功能转型升级,后者又进一步强化大都市圈的空间集聚、成长动力和空间结构优化,提高整体发展的能力和效率。因此,大都市圈成长动力主要包括区位动力、结构动力和市场动力。

The difference of geographic region initiates the spatial differentiation of economic activities,and lead to the diversity and complementarity of urban functions.At the same time,the limited difference between geographic locations brings out the competence among the cities.The spatial actions of complementarity and competence can form a hierarchy system in metropolitan circles which is dynamic stabilization,and also improve it growth.In practice,the development of regional transport can further enlarge market potential,improve the transformation and upgrade urban functions,and then the latter can improve the spatial agglomeration,and enhance the growth dynamic,and optimize the spatial structure in the metropolitan area.That can also improve the develop ment efficiency.The growth dynamic of metropolitan circle includes locational dynamic,structural dynamic and market dynamic.
