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。
From the perspective of prefecture-level cities and districts and counties, the spatial and temporal evolution of the industrial value section of the Yangtze River Delta is analyzed. The results show that: in the prefecture-level city level, the spatial economic structure characterized by “value section ” is increasingly evident and forms a “core-periphery ” spatial pattern; at the district-county level, The types of value sections show consistency with the prefecture-level cities, while suburban and county-level cities and counties show differences. The spatial and temporal evolution of the industrial value sections in the Yangtze River Delta is closely related to the progress of regional economic globalization. Although the financial crisis zone But negatively promoted the upgrading of the regional value section, which brought opportunities for the transformation and upgrading of the regional economy.
