摘要: 为探讨高铁对泛长三角地区可达性造成的影响,选取加权平均旅行时间、经济潜力及日常可达性作为3个主要评价指标,分析有无高铁两种情形下,泛长三角地区可达性的动态变化,并探讨该变化所带来的空间效应。结果显示:高铁的运营使得各城市的可达性均得到了大幅优化,各城市加权平均旅行时间平均缩减了50.57%,经济潜力值平均增幅达到了99.62%,省级行政中心的一日交流圈面积占比增长至95.92%;高铁带来的时空效应、区位增强效应、同城化效应和一体化效应加强了城市间的社会经济联系同时,还推动了区域空间格局的重塑;因高铁对各城市可达性的差异化提升,泛长三角地区的空间极化将进一步凸显,上海、南京、杭州等中心城市发挥其区位优势,对周边城市产生强劲的经济带动作用,而宣城、阜阳等无高铁通过城市因相对区位的渐弱,将被日益边缘化,重组后的“核心-边缘”格局已初现端倪。

Abstract:  

Taking a case of the Pan-Yangtze River Delta Region, by using average travel time, economic potential and daily accessibility as the three main evaluation indexes, to explore the influence of high-speed railway on the accessibility of the Pan-Yangtze River Delta Region. In addition, the paper analyses the dynamic changes in accessibility of the Pan-Yangtze River Delta in the presence or absence of high-speed railway exists, and reveals the spatial effect result from the changes. It is conclude as follows:(1) The high-speed railway greatly improved traffic accessibility of the city in Pan-Yangtze River Delta Region, the weighted average travel time was reduced by an average of 50.57%, the average growth rate of the economic potential was 99.62%, and the proportion of the daily exchange area of the provincial administrative center increased to 95.92%;(2) The operation of high-speed railway has led to the effect of space-time compression, location enhancement and the trend of regional integration. Not only it strengthens the social and economic links between cities, but also reshapes the regional spatial pattern;(3) The spatial polarization characteristics of the Pan-Yangtze River Delta region will be further highlighted, because of the spatial imbalance improvement of accessibility. Central cities such as Shanghai, Nanjing, and Hangzhou will exert their regional advantages to generate strong economic growth for neighboring cities, while cities without high-speed railway will be increasingly marginalized due to weaker relative locations, such as Xuancheng and Fuyang. As a result, the “core-edge” pattern after the reorganization of regional space has begun to emerge.
