城市固体废弃物资源化共生网络脆弱性研究——基于某市无废城市建设的案例分析

Vulnerability Study of Municipal Solid Waste Resource Symbiosis Network:Based on a Case Study of Zero⁃Waste City Construction in a City

城市固体废弃物资源化共生网络是实现无废城市的最佳途径,城市固体废弃物共生网络容易受多种因素的影响,包括再生资源需求萎缩或标准的变更,突破性技术的出现以及由于市场、技术、政策中存在的信息不对称引发的利益冲突等。资源化共生网络系统的动荡或非正常运行,制约了无废城市的建设和发展。基于此,研究梳理了中国无废城市的建设背景及发展过程,以国内某城市为例,介绍了该市无废城市建设的基本情况和成果,构建了固体废弃物资源化共生网络,并运用MATLAB程序进行了仿真实验。研究表明:该市的城市固体废弃物共生网络尚未形成嵌套模式,不同产业链的共生模式存在差异,并从推进信息化建设、关注核心企业运行和开展技术创新3个方面对城市固体废弃物资源化共生网络的脆弱性进行了治理。

Municipal Solid Waste Resource Symbiosis Network(MSWRSN)is the best way to achieve zero⁃waste cities.However,MSWRSN is vulnerable to a wide range of factors.Examples include shrinking demand for recycled resources or changes in standards,the emergence of breakthrough technological innovations,and conflicts of interest arising from serious information asymmetries in markets,technologies and policies.The system often falters or operates abnormally,constraining the construction and development of waste⁃free cities.On this basis,this study combs the construction background and development process of zero⁃waste cities in China.The study specifically takes a city in China as an example and introduces the basic situation and results of a zero⁃waste city construction in that city.After study in that city,a symbiotic network for solid waste resource utilization is constructed and simulation experiments using the MATLAB program is conducted.The results indicate that the city′s MSWRSN has not yet developed a nested pattern,and that there are differences in the symbiosis patterns of different industrial chains.Based on the conclusions of the study,it is proposed to manage the vulnerability of MSWRSN management from three aspects,which include promoting informationization,focusing on core business operations and developing technological innovation.
