在测度经济空间分异程度和识别经济空间组织型式的基础上系统分析1990—2006年黄河流域经济空间分异的态势。结果表明:黄河流域经济空间分异主要表现为流域东部与中西部之间日趋加剧的经济分异,目前东部经济空间已现多核心—边缘结构,呈现一定程度的较高水平的均衡化趋势,而中西部经济增长水平总体较低,经济空间中只有少量增长极和增长轴;随着我国对外开放向内陆深入推进,黄河流域中西部内内蒙古和河南的相对经济实力增强,其他省区的相对经济实力减弱,中西部经济空间格局越来越不均衡。由此推断,1990年以来黄河流域经济空间分异与流域内改革开放进程的差异密切相关。
On the basis of measuring the degree of economic spatial differentiation and identifying the type of economic space organization, this paper systematically analyzes the trend of economic spatial differentiation in the Yellow River Basin from 1990 to 2006. The results show that the economic spatial differentiation of the Yellow River Basin is mainly characterized by the increasing economic differentiation between eastern and central and western regions of the Yellow River Basin. At present, there is a multi-core-periphery structure in the eastern economic space, presenting a relatively high level of equilibrium. However, the economic growth in the central and western regions is generally low, with only a small number of growth poles and growth axes in the economic space. With the deepening of China’s opening up to inland areas, the relative economic strength of Inner Mongolia and Henan in the central and western Yellow River increased. As the relative economic power weakened, the economic space in the central and western regions became more and more uneven. It can be inferred that the economic spatial differentiation of the Yellow River Basin has been closely related to the differences in the process of reform and opening up in the basin since 1990.
