城镇商业活动空间相互作用的测算方法探讨

Discussion on the method of calculating spacial interacion about business address in town

基于空间相互作用原理,运用最短邻近距离法测量两个行业间的商铺距离,用其与行业内部商铺距离进行对比,测算两行业的相对空间关系。通过计算获得最邻近距离指数、相对邻近距离指数和最邻近距离比率三个指标。以三个指标的涨落变化作为判断相互作用关系的标准,行业间空间关系可描述为相对靠近、随机靠近和相对远离三种状态。

Based on the principle of special interaction, the paper uses the shortest distance method to measure the distance between the shops of two industries, contrasts them to the distance of shops of one industry, and estimates the relative spatial relations between two industries. Then three indexes are worked out. They are ：the nearest distance index, relative near distance index, and the nearest distance ratio index. The change in the three indexes is regard as a standard to determine the spatial interaction. So we can describe the inter - industry spatial relationship as three states： concentrated, random and separate.
