摘要
2017年《生活垃圾分类制度实施方案》正式公布实施,但现阶段分类效果仍不显著。原因之一在于生活垃圾回收涉及多利益主体,各利益主体的纠纷和冲突阻碍我国生活垃圾分类回收目标实现。寻求解决各利益主体冲突的途径,有助于较好地解决上述问题。作者通过Markov随机图模型和高阶随机图模型对城市生活垃圾分类回收利益网络结构和关系进行分析。研究结果发现:整个生活垃圾分类回收体系形成了众多节点,各节点间彼此相互影响,产生了连接或分散或紧密的子群。其中,政府组织内部节点存在互惠性,网络等级闭合路径显著,说明政府组织内部会形成紧密度较高但直径较短的核心结构,特别是存在隶属关系的节点。而同级别机构或非隶属关系的节点之间联系紧密度较低,各自为政。政府组织与非政府组织之间网络紧密度较低,没有形成强有力的交互影响关系,造成生活垃圾分类回收利益隔离,难以对生活垃圾分类回收形成强有力的管理。因此,现阶段应该加强不同组织间的合作,形成利益共享机制,提高城市生活垃圾分类回收可持续性。
The implementation plan of The Domestic Waste Classification System was officially announced in 2017, but the classification effect is still insufficient at this stage. The recycling of domestic garbage involves multi-stakeholders, and the disputes and conflicts of various stakeholders have become an important obstacle to the realization of the goal of domestic waste separation and recycling. Seeking to resolve the conflicts of various stakeholders can help solve the above[JP3] problems better. This paper uses the exponential random graph model to analyze the structure and relationship of urban domestic waste sorting and recycling interest network through Markov random graph model and high-order stochastic graph model. The research results show that the whole domestic waste sorting and recycling system forms a large number of nodes, and each node interacts with each other, resulting in connected or scattered or tight subgroups. Among them, the internal nodes of government organizations have reciprocity, and the network level closed path is significant, indicating that the core structure of the government organization will form a tighter but shorter diameter, especially the nodes with affiliation. The relationship between the nodes of the same level or the non-affiliation relationship is relatively tight, and each is in a political position. It is difficult to form a strong management of the classification and recycling of domestic waste. Therefore, at this stage, cooperation between different organizations should be strengthened to form a benefit-sharing mechanism to promote the sustainability of urban domestic waste separation and recycling.
