Sustainable development research of resource-exhausted cities based on system dynamics: a case study of Sdzz

As suppliers of basic energy and raw materials, resource-based cities have played an important role in China's induzzstrialization process. However, with the high intensity of resource development and utilization, many resource-based cities are faced with economic and social problems such as resource exhaustion and economic stagnation. How to achieve sustainable development of resource-based cities has become a hot topic both in government and academia in recent times. Zaozhuang City of Shandong Province (Sdzz) was once a famous coal resource-based city in China, but after more than half a century of mining, coal resources have been almost exhausted. Taking Sdzz as an example, based on the theory of complexity, this paper analyzes the development situation of the major industries in Sdzz by using location entropy. On this basis, we use system dynamics to analyze the economic development of Sdzz from the perspectives of resources, environment, population, technology, economy, etc. The research results indicate that prioritizing the development of high-end manufacturing and strengthening financial and technological investment are effective ways to improve the efficiency of Sdzz's economic development. Finally, several constructive countermeasures and suggestions are put forward based on balancing the interests of all parties.
