【摘要】 从地级市和区市县两个空间层面,对长三角地区产业价值区段的时空演化进行了分析。结果发现:在地级市层面,以"价值区段"为特征的地区空间经济结构日益明显,并且形成"核心—外围"的空间格局;在区市县层面,市区单元的价值区段类型与所在地级市显示出一致性,而郊区、县级市和县单元则显示出差异性;长三角地区产业价值区段的时空演化与区域经济全球化进程密切相关,尽管金融危机带来消极影响,但是却倒逼式地促进了地区价值区段的提升,为地区经济发展转型和产业升级带来了机遇。更多还原

【Abstract】 In the process of economic globalization, urban and region has increasingly integrated into the global economy. This paper discusses temporal and spatial transformation of value-added hierarchy in the Yangtze River Delta Region both on the prefecture-level city and on the county-level city. Four features have been identified. First, the valueadded hierarchy continues to rise which reflects economic development in the Region. Secondly, on the prefecture-level city, the spatial structure characterized in value- added hierarchy has become increasingly evident while a "core-periphery" spatial pattern has formed. Thirdly, on the county- level city, types of the urban districts are the same as the prefecture- level city while types of the suburb units, county- level cities and counties show differences. Fourthly, this process is closely related to economic globalization. Despite the financial crisis, the value- added hierarchy continues to rise which brings opportunities for economic restructuring and industrial upgrading.更多还原
