全球城市的空间二元化机理研究

Research on the Spacial Dualization of Global Cities

作为世界经济管理与控制中心的全球城市,是国内外经济联结点与生产要素通道。全球城市具有外向型与服务型产业发展特征,城市产业的外生性较为明显。在相对过剩的劳动力供给条件下,资本、企业与居民对城市空间竞争进一步加剧。城市外向型产业发展扩大了居民收入差距,拉大了资本与劳动力对空间竞争能力差异,加剧了城市空间分化:中心城区经济密度趋于上升,而郊区空间对外呈蔓延式扩张;城市空间的镶嵌式隔离与二元分化趋于明显。"二元城市"问题是困扰全球城市至今的经济与社会问题,突出反映了经济全球化下国际经济生产的二元化特点。因此,必须运用制度把城市空间二元分化控制在合理范围之内。

As the management and control center of world economy,global cities are the wiring points and the passageways of external and domestic economy.Global cities have exported and imported-oriented industries especially have serviced industries oriented characteristic.The industrial structure of cities are exogenous and not endogenous.Under the condition of over labour supply,the competition between capitals,enterprises and residents for urban space become fierce.The exogenous industrial structure of global cities enlarges social income distribution gap and the differentia of the ability of spacial competition,intensifies spacial differentiation：the industrial density of central urban areas in global cities have increased,the surburbs have sprawled;cities have more and more of characteristic of social isolation and spacial dualization.These reflects the characteristic of dualization of international production under the condition of informationization and globalization.It should be controlled within reasonable extent by using institutions.
