高雄縣市合併前後捷運旅運量集中度之變化

Abstract

本文以高雄捷運入站集中度與出站集中度為基礎，探討2008年至2015年此8年間高雄地區整體及各站出入旅運量的變化。文中採用Herfindahl-Hirschman指數 (簡稱HHI) 分析集中度，比較2008年至2015年間的出入站旅客人數之數據。研究結果發現：高雄捷運旅運量於2012年搭乘人數突破6,000萬人次且逐年穩定中，各站的出入站旅運量除了昔日高雄市中心的美麗島站、中央公園站之外，都有成長的趨勢。透過Mann-Whitney檢定發現，入站與出站旅運量相似，並無明顯差異，顯示同站進出的情形相當普遍。分析出入站的HHI之後發現，HHI在入站與出站都呈現下降的趨勢，顯示高雄捷運出入站人口並不集中且更趨於分散。

This thesis analyzes the concentration ratios of inbound and outbound passenger volumes by the Herfindahl-Hirschman Index (HHI), in order to explore the change in passenger volumes MRT stations in Kaohsiung from 2008 to 2015. The results show that: The passenger volume of Kaohsiung MRT has over 60 million in 2012 and kept stable growth except for Formosa and Central Park stations. The Mann-Whitney test finds no significant difference in inbound and outbound passenger volumes, showing that accessing the same station is quite common. The HHI indexes for inbound and outbound passengers both drop year by year, showing that passenger distribution gets more disperse year by year.
