| 摘 要： | 为合理利用港口资源、减少恶意竞争,提出基于位序-规模法则的港口群发展演化规律研究方法。以吞吐量为衡量港口规模的指标,以变异系数、基尼系数等指数研究区域港口群规模差异,以首位度指数判断区域港口群是否服从位序-规模分布,进而基于位序-规模理论研究区域港口群规模分布,定量分析区域港口群发展演化规律。实例分析以欧盟港口群为研究对象,结果表明:欧盟港口群规模差异较大,不均衡程度会逐年增大;欧盟港口群符合位序-规模法则,随着港口位序由高到低,吞吐量增长率会随之减小。 |
| 关 键 词： | 港口；位序-规模法则；规模分布；演化规律 |

| Abstract: | In order to make rational use of port resources and reduce the malicious competition between ports,this paper presents a method for the study of the evolution law of port groups based on the rank-size rule.This method uses throughput as an index to measure port scale,and adopts variation coefficients and Gini coefficients to study the difference of regional port group scale.Besides,the primacy index is used to determine whether the regional port group obeys the rank-size distribution.Then,the rank-size rule is applied to study the scale distribution of regional port groups and quantitatively analyze development and evolution law of regional port group.Finally,we choose the EU ports group as a case study.The results indicate that the size of the EU port group is quite different and the degree of imbalance will increase year by year;the EU port group conforms to the rank-size rule,and the throughput growth rate will decrease with the ports rank from high to low. |
| Keywords: | port the rank-size rule scale distribution evolution law |
