文章以中蒙俄经济走廊西线、东线铁路为对象,在高速铁路情境下,利用可达性指标测度沿线城市可达性的动态变化,研究了线路升级提速后对沿线区域和城市的空间效应.研究发现:①未来中蒙俄高铁的运行使得沿线可达性大幅提升,高铁1d交流圈覆盖全线,东线的可达性及其改善程度略强于西线.②中国城市可达性强于俄罗斯和蒙古国城市,表现出"东南高、西北低"的格局特征.蒙古国城市可达性改善程度大于中国和俄罗斯城市,呈线路"中间高、首末低"的格局特征.③高铁可达性的提升加速沿线格局的演变和重塑.人口和经济重心向中蒙俄高铁轴带迁移,极化效应凸显;高铁轴带内部边界效应消失,一体化效应显现;走廊沿线贸易创造和转移效应加深,同走廊外的跨境投资规模增大.
Accessibility and Spatial Effect of China-Mongolia-Russia High-speed Railway
Taking the western and eastern railways of"China-Mongolia-Russia Economic Corridor"(CMREC)as research objects,this paper measures the dynamic change of urban accessibility based on the accessibility index,analyzes its spatial effect of the railway upgrade and speeding on the regions and cities along the railways.It's found that:1)The opening of China-Mongolia-Russia high-speed railway(HSR)will greatly improve the regional and urban accessibility level along the CMREC.It will shorten the whole journey to only one day.The accessibility level and its improvement degree of the eastern railway line are stronger than that of the western railway line.2)The accessibility level of Chinese cities is stronger than that of Russian and Mongolian cities,showing the pattern which is higher in the southeast of CMREC and lower in the northwest of CMREC.The improvement degree of urban accessibility in Mongolia is greater than that in China and Russia,showing the pattern which is higher in the middle of CMREC and lower at the beginning and end of CMREC.3)The accessibility improvement of high-speed railways accelerates the evolution and reshaping of the pattern along the CMREC.The regional population and economic gravity centers will move to the China-Mongolia-Russia HSR axial belt,and its spatial polarization phenomenon will further enhance.The internal boundary effect of the China-Mongolia-Russia axial belt will disappear,and the integration effect of boundary areas and boundary cities will appear.The regional trade creation and transfer effects has deepened,and the scale of cross-border investment has increased along the CMREC.
