Path Analysis of Coordinated Development of Resource, Environment and Economy in Beijing-Tianjin-Hebei Region

Promoting the coordinated development of resource, environment and economy in Beijing-Tianjin-Hebei Region is one of the goals of the coordinated development for this region. The economy-wide material flow analysis was combined with system dynamics in this study to set up a system dynamic model of resource-environment-economic system for exploring the path of coordinated development of resource-environment-economy in this region. Economic accelerated development model, inertia development model, resource-environmental protection model and coordinated development model were set up for comparison study. The results of the study show that under the coordinated development model, the development of social economy maintains relatively fast, and the pressure on resources and environment in the region will be reduced by adjusting the industrial structure, increasing investment in environment and technology, and improving the utilization and recycling rate of industrial solid wastes. The improvement of coordinated development of this region under this model is far higher than the other three models. In conclusion, the coordinated development model is the best one for coordinated development of resource-environment-economy in this region, however, Hebei Province still needs to pay attention to resolving the rising pressure on resources and environment in the process of urbanization.
