Under the background of “the Belt and Road” and “China-Mongolia-Russia economic corridor” initiatives, we studied the urban accessibility level and regional spatial effect of the west line and east line of China-Mongolia-Russia economic corridor in the high-speed rail (HSR) environment. The results are as following. (1) The operation of China-Mongolia-Russia HSR will greatly improve the urban accessibility level, which will shorten the whole journey time to two days along China-Mongolia-Russia economic corridor. The regional space-time convergence effect will be very strong in the China-Mongolia-Russia HSR environment. (2) The accessibility level and its improvement degree of the China-Mongolia-Russia east line are stronger than those of the west line. The accessibility level of different countries differs: China > Russia > Mongolia. The accessibility improvement degree of different countries also differs: Mongolia > Russia > China. Spatially, the accessibility improvement degree of the cities, which are located in the middle of the line is stronger than those cities at the beginning and end of the line. (3) Affected by the China-Mongolia-Russia HSR environment, the spatial polarization effect of China-Mongolia-Russia HSR axial belt will be further enhanced. The internal boundary effect of the China-Mongolia-Russia HSR axial belt will disappear. New HSR economic growth poles will occur, promoting the formation of point-axis system. China-Mongolia-Russia cross-border trade creation and transfer effects will be deepened.
在“一带一路”和“中蒙俄经济走廊”倡议的背景下，我们研究了高铁环境下中蒙俄经济走廊西线和东线的城市可达性水平和区域空间效应。结果如下。（1）中蒙俄高铁的运营将极大地提高城市可达性水平，将沿中蒙俄经济走廊的全程旅行时间缩短至两天。中蒙俄高铁环境下的区域时空收敛效应将非常强烈。（2）中蒙俄东线的可达性水平及其改善程度强于西线。不同国家的可达性水平不同：中国>俄罗斯>蒙古。不同国家的可达性改善程度也不同：蒙古>俄罗斯>中国。空间上，位于线路中部的城市的可达性改善程度强于线路两端的城市。（3）受中蒙俄高铁环境的影响，中蒙俄高铁轴向带的空间极化效应将进一步增强。中蒙俄高铁轴向带的内部边界效应将消失。新的高铁经济增长极将出现，促进点轴系统的形成。中蒙俄跨境贸易创造和转移效应将加深。
