【摘要】：基于时间和经济两种维度,以哈大与郑西两条欠发达地区高铁线路为研究对象,利用加权平均旅行时间与经济潜力综合测度两条高铁运营前后沿线城市可达性的动态变化及空间差异,结果表明:高铁开通后,沿线城市可达性明显改善,哈大高铁可达性综合改善程度强于郑西,且内部可达性变率相对差异较小;哈大高铁可达性变率呈线路中间大、首末小的态势,郑西高铁经济潜力变率呈自东向西递减趋势;哈大高铁明显提升了吉林南部与辽宁北部的核心地位,可达性获益的空间集聚效应凸显;郑西高铁显著拉近了中原和关中地区,以郑州、洛阳、西安为核心的"古都经济带"初露端倪,未来可向西对接"丝路经济带",打造沟通中国与欧亚大陆跨国经济走廊。
[Abstract]:Based on the two dimensions of time and economy, this paper studies two high-speed railway lines in the underdeveloped areas of Hada and Zhengxi. Using weighted average travel time and economic potential to measure the dynamic changes and spatial differences of urban accessibility before and after the operation of the two high-speed rail lines, the results show that the accessibility of the cities along the route has been improved obviously after the opening of the high-speed rail line. The degree of comprehensive improvement of high-speed rail accessibility in Harbin and Dalian is stronger than that in the west of Zhengzhou, and the relative difference of the internal reachability rate is relatively small, and the rate of accessibility change of high-speed rail in Harbin and Dalian shows a trend of large middle line, small first and last stage, and the economic potential change rate of high-speed rail in the west of Zhengzhou decreases from east to west. The high-speed railway in Harbin and Dalian has obviously enhanced the core position of southern Jilin and northern Liaoning, and the spatial agglomeration effect of reachable benefits has been highlighted; the high-speed rail in the west of Zheng has significantly brought the Central Plains and Guanzhong areas closer to Zhengzhou and Luoyang. Xi'an as the core of the "ancient capital economic belt" emerging, the future can be docked to the west "Silk Road Economic Belt", to create a cross-national economic corridor between China and Eurasia.
