摘要
近10年来中国高速铁路快速发展,对城市发展的影响正逐步显现。本文从市场潜力角度研究这一影响,根据《全国铁路旅客列车时刻表2012.07》统计获得的城市之间平均旅行时间和发车频次数据重新定义市场潜力函数,对比中国地级及以上城市普通铁路和叠加高速铁路之后的市场潜力特征,探讨高铁对城市市场潜力的提升作用,并从中分离出时间压缩效应和频次效应。研究发现:1普通铁路市场潜力呈现"多中心—廊道"结构,市场潜力高的城市主要分布在长三角、珠三角、京津冀城镇群内,以及京广、京沪、京哈等重要铁路线沿线;2叠加高速铁路之后城市市场潜力整体上仍呈现"多中心—廊道"结构,且多中心结构更为突出;3京沪、沪杭铁路沿线城市和东南沿海宁波—厦门段客运专线沿线城市的高铁效应最大;4高铁连接的109个城市时间压缩效应的平均值为31.3%,频次效应的平均值为68.7%,频次效应是高铁效应的主要形式。
In the past ten years, high-speed railway has rapidly developed in China and its effect on urban development is gradually revealed. This paper explores the impact of high-speed railway on market potential of 268 Chinese cites at the prefecture level or above in 2012. First, market potential function is redefined based on the average travel time and train frequency between 268 cities obtained from the railway train schedules. Second, to examine the high- speed railway effect this research compares market potential of cities with and without highspeed railway. Existing studies of high- speed railway effect have primarily focused on its contribution to time saving and paid little attention to increased train frequency. In this paper, both travel time and train frequency are analyzed. The results show that:(1) Market potential of Chinese cities without high- speed railway exhibits a multi-center and corridor structure. Cities with high values of market potential are mainly located in the Yangtze River Delta Region, Pearl River Delta Region, Beijing- Tianjin- Hebei Region, and along some major railway lines such as the Beijing-Guangzhou Railway Line, Beijing-Shanghai Railway Line, and Beijing-Harbin Railway Line;(2) Market potential with high- speed railway also presents a multi- center and corridor structure, but has higher densities around the centers;(3) the high-speed railway effect of cities along the Beijing-Shanghai Railway Line, Shanghai- Hangzhou Railway Line, and Ningbo- Xiamen Special Railway Line is most pronounced,which significantly facilitates the growth of market potential in these cities;(4) The average value of the timesaving effect of 109 cities connected by high-speed railway is 31.3% and the average value of frequency effect is68.7%, which is the most significant part of the high-speed railway effect.
