Coordinated Degree Assessment on Transport Infrastructure Construction with Regional Economic-Socio-Ecological Development: A Study of the Areas Along the Main Traffic Line in Mongolia

The China-Mongolia-Russia Economic Corridor is a priority area of the six major economic corridors planned by “the Belt and Road”. As a bridge connecting China and Russia, Mongolia's transportation infrastructure construction (TIC) is the key issue to the transportation interconnection among China, Mongolia and Russia. However, the existing research is insufficient to support the actual construction needs. Therefore, this research set the regions along the main north-south traffic line of Mongolia as the study area. We established a regional economic-society-ecology-transportation assessment model (ESET model) to quantitatively assess the construction and development degree of the four subsystems. The results showed that from 2005 to 2015, the development level of the ESET systems gradually increased. The coordination degree between TIC and ESE development has been continuously improved, and most aimags have been optimized as primary coordination. The research results will provide a decision-making basis for the TIC in the China-Mongolia-Russia Economic Corridor, as well as a scientific and technological support for the implementation of the “Belt and Road”.
