摘要
高铁已经成为我国客流主要的运输方式,高铁开通对沿线城镇经济活动带来重要影响。本文基于2008—2017年双源夜间灯光数据集,以沪昆高铁为实证研究对象,在县域尺度下运用多时点DID模型,定量化地探究了高铁开通运营对周边城镇经济活动的影响。研究结果表明:(1)沪昆高铁开通运营对沿线城镇的人口密度、固定资产投资等社会经济活动指标具有正向促进作用,且城镇夜间灯光值与旅行时间距离呈现正"U"型关系;(2)高铁运营对所在城镇的促进作用最大,对18~64分钟时间距离段内的城镇造成虹吸效应,削弱邻近城镇的经济增长;同时会对64~151分钟距离段的城镇经济活动产生促进影响,该影响随着距离的增加,促进效果逐渐减弱。直到在151分钟后,促进效果消失。为更充分发挥沪昆高铁带来的经济发展契机,完善产业布局,促进基础交通建设和产业、城乡融合发展,应建立综合立体的城市交通网,缩短边缘区与核心区的时间距离。中心城镇应扩大经济辐射范围,减少经济分割,与中小城镇协同发展。
High-speed railway has become the main way of passenger transportation in China,but there is a lack of quantitative research on the impact of high-speed railway on the economic activities of cities and towns along the line.Based on DMSP/OLS and NPP-VIIRS night light data set from 2008 to 2017,the multi-time DID model was used to analyze the impact of the Shanghai-Kunming high-speed railway on economic activities in surrounding towns.The research conclusions are as follows:(1)Shanghai-Kunming high-speed railway has a positive promotion effect on economic activities in towns along the route,and the relationship between night light value and travel time distance in towns presents a positive"U"shape;(2)High-speed railway has the greatest promotion effect on the towns where it is located,while towns along the high-speed railway cause a siphon effect on those towns within a distance of 18 to 64 minutes,which weakens the economic growth of neighboring towns;At the same time,it has a promoting effect on urban economic activities in the distance of 64~151 minutes,and the promoting effect gradually weakens with the increase of distance.The effect disappeared after 151 minutes.In order to give full play to the economic development opportunities brought by The Shanghai-Kunming high-speed railway,improve the industrial layout,promote the basic transportation construction,industry and urban-rural integration development,a comprehensive three-dimensional urban transportation network should be established to shorten the time distance between the marginal areas and the core areas.Central cities and towns should expand the scope of economic radiation,reduce economic division,and develop in coordination with small and medium-sized towns.
