区域经济联系测度方法述评

REVIEWS ON METHODS MEASURING THE INTERREGIONAL ECONOMIC CONNECTION

区域研究是地理学的核心之一。区域经济联系测度是区域研究的焦点。在系统总结区域经济联系测度的理论与方法的基础上,本文认为区域经济联系测度一般依循尺度确定—区域划分—区域联系测度的路径;测度区域经济联系的主要指标有可达性、经济影响范围、经济联系强度、经济隶属度等。城市在区域网络中的作用、位置是区域经济联系测度的重点。通过区域经济联系强度的测度,有助于区域和城市发展定位,并指导规划。近年来城市化、信息化、全球化的快速发展对区域经济联系的测度提出了新的挑战,需要综合不同的方法或发展新方法来应对。

Regional study is one of the cores of geography. As regional economic development involves not only the internal relations but the interregional relations as well, so the interregional relations are often see as more important. Researchers have paid great attentions to the measurement of interregional economic rela- tionships, especially the city connection on some economic zone. This paper systematically summarizes the theories and methods on measuring interregional economical relationships, and clarifies the general approach- es to measure the interregional relationships which is scale identify-boundary identify-the measurement of the interregional relationships. A multi-scale approach that simultaneously uses larger-scale and smaller-scale measurement can identify important relationships of the system that might otherwise be overlooked. The cen- tral function intensity index is always applied to distinguish the hierarchical level of cities. Boundaries of re- gions are critical which define the space radiation area of cities; the common way to identify boundaries of re- gions or radiation area of cities is breaking-point formula. The function and location of cities in regional net- work is the focus of the measurement of interregional economical relationships. The measurement of the in- terregional economical relationships can benefit the development of the cities and shed light on the planning of the cities and regions. Recently the development of urbanization, information technology and globalization challenges the measurement of interregional economic relationships. The transportation development such as the plane and high-speed railway decreased the dependence on distance. Information technology and global- ization made it possible to distribute and access resources globally.
