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.
