TL;DR: Wang et al. as mentioned in this paper established a system dynamics model named EECP and dynamically simulated CO2 emission trends under different conditions, which can provide reference and help for other traditional industrial regions with large CO2 emissions.

TL;DR: Wang et al. as discussed by the authors constructed a Circular-Economy-Effect and Policy-Simulation-System-Dynamics (CEEPS-SD) model, evaluated the ecological economic comprehensive effects and simulated the future development trends of the circular economy system (CES).

TL;DR: Wang et al. as mentioned in this paper evaluated the coupling coordination degree between urbanization and the eco-environment in Mongolia during 2000-2016, and found that the main contributor of the urbanisation and the environment subsystem were demographic urbanization, and ecoenvironment endowment, respectively, and proposed a six-layer eco-city establishing green development pattern to provide scientific support for Mongolia.

TL;DR: Wang et al. as discussed by the authors analyzed the tourism eco-efficiency of 31 provinces in China using an undesirable output model of a slack-based model (undesirable-SBM) for data envelopment analysis.

TL;DR: Wang et al. as discussed by the authors proposed designs for the east and west China-Mongolia-Russia high-speed railways and policy suggestions to mitigate construction risks, including developing innovative cooperation of the "high-speed railway for resources and market", strengthening communication and technology dissemination, and applying innovative engineering techniques and setting buffers; establishing collaborative prevention and control systems to mitigate the three major ecological risks in the China, Mongolia and Russia trans-border areas.
