中文摘要：

本文首先对系统动力学应用到医疗废弃物物流网络中的可行性进行深入分析，并从社会系统、物流系统和经济系统三个方面选取相应的要素指标构建指标体系，深入分析指标体系中的就医人数、回收企业和GDP总量与系统内其他要素之间的因果关系，并利用系统动力学的相关原理绘制出要素之间因果关系图。最后，根据要素间的因果关系构建出医疗废弃物物流网络演变模型。

英文摘要：

First, the article made an in-depth analysis of the feasibility for appling the system dynamics to a medical waste logistics network. Then, the corresponding elements from the three perspectives of social system, economic system and logistics system were selected, and the causal relationship among patients to the hospital, recycling enterprises, GDP gross and other factors in the index system was deeply analyzed, as well as the causal relationship diagrams among the influence factors were drawn using the correlation theory of the system dynamics. Finally, an evolution model of the medical waste logistics network according to the causal relationship among the factors was built.
