论文摘要
电力法分布是几种自然和社会现象的特征。城市的ZIPF法律就是其中之一。该研究认为，全球规律性是否独立于城市的不同空间分布的问题。为此，用随机数生成了典型的Zipfian等级大小分布。然后将此分布施放到空间坐标的不同设置中。为了进行估计，变量等级和大小在标准空间计量方案中由空间溢出效应补充。结果表明距离和连续性效应很重要。三个国家分析进一步证实了这一发现。
Power law distributions characterise several natural and social phenomena. The Zipf law for cities is one of those. The study views the question of whether that global regularity is independent of different spatial distributions of cities. For that purpose, a typical Zipfian rank-size distribution of cities is generated with random numbers. This distribution is then cast into different settings of spatial coordinates. For the estimation, the variables rank and size are supplemented by spatial spillover effects in a standard spatial econometric approach. Results suggest that distance and contiguity effects matter. This finding is further corroborated by three country analyses.
