| Abstract | Resource-based cities, which account for 43.6% of China's cities, have the industrial problem of heavy pollution, low efficiency, and irrational structure. Therefore, how to improve the sustainability of the industries in resource based cites has become an important issue. First, from the perspective of ecology, this paper uses Lotka-Volterra model to reveal three basic sustainability promotion mechanisms of industries: the construction of circular economy system, the refinement of resource-based industries, and the cultivation of non-resource-based industries. Then, in order to explore how to use the three mechanisms to achieve better performance, a system dynamics model is established and the situation simulation is carried out. The results show that simply combining the three mechanisms has the worst performance, while the phased mode of "resource-based industry-* circular economy-* tertiary industry" can improve the performance by 164.82%. In addition, the advantages and disadvantages of the above three mechanisms are also found. Construction of a circular economy can improve the environment and its economic output grows quickly while it excessively relies on the second industry. Refinement of resource-based industries can greatly promote economic output while crowding out non resource-based industries and destroying the environment. Cultivation of non-resource-based industries requires a lot of resources. |
