摘　　要：选取呼包鄂榆城市群作为研究对象,利用可达性模型、经济潜力模型和经济联系强度模型,对比分析了呼包鄂榆城市群开通高铁前(2009年)和开通高铁后(2020年)的加权平均旅行时间、经济潜力和经济联系强度的各项指标的变化.结果表明:①高铁开通后呼包鄂榆城市群内部各市的加权平均旅行时间缩短一半,城市群内部的交通整体可达性提升显著;②高铁开通后城市群的中心城市发展迅速,呈现出“中心扩散型”发展模式;③高铁开通后呼包鄂榆城市群的经济潜力提升显著,各个城市的经济实力发展迅速,各城市间联系发展更为密切;④高铁开通前后的城市群内部经济联系强度提升明显,能够直观的看出高铁可达性以及缩短平均旅行时间对经济联系强度的影响.This paper takes the Hubao-Eyu urban agglomeration as the research object,and compares and analyzes the changes of weighted average travel time,economic potential and economic linkage intensity before the opening of high-speed rail(2009)and after the opening of high-speed rail(2020)by using accessibility model,economic potential model and economic connection intensity model.The results show that:①After the opening of the high-speed railway,the weighted average travel time of each city in the Hubao-Eyu urban agglomeration is halved,and the overall accessibility of traffic within the urban agglomeration is significantly improved.②After the opening of high-speed rail,the central cities of urban agglomerations have developed rapidly,showing a“central diffusion”development model.③After the opening of the high-speed railway,the economic potential of the Hubao-Eyu urban agglomeration has increased significantly,the economic strength of each city has developed rapidly,and the links between cities have developed closer.④The intensity of economic ties within urban agglomerations before and after the opening of high-speed rail has increased significantly,and the impact of high-speed rail accessibility and shortening the average travel time on the strength of economic ties can be intuitively seen.
