【摘要】：脆弱性理论的不断深化和实践发展为城市废弃物资源化利用研究提供了新的视角和方向。本文通过梳理国内外文献,从城市废弃物资源化利用网络的供应、回收、资源化和市场化四个环节提取24个脆弱性影响因素,并将其映射到敏感性、适应性和恢复力三个维度。建立DEMATEL-ISM-ANP集成方法,采取专家问卷调查获取数据开展实证研究,解析各影响因素组和因素间的相互作用关系,并计算各脆弱性因素的影响强度,进而采用综合指数法开展脆弱性评价,识别出关键影响因素并探讨其影响机理。研究结果表明:(1)城市废弃物资源化利用网络脆弱性影响因素具有明显的层次化网络结构特征,24个影响因素可以划分为驱动、互动、随动和独立四种类型;(2)我国城市废弃物资源化利用网络脆弱性指数为3.351,敏感性指数、适应性指数和恢复力指数分别为3.688、3.042和3.362,都处于中高水平,亟需加强调控治理;(3)废弃物供需不匹配是影响系统敏感性的关键因素,资源化效益不佳和回收行为不规范降低了系统适应能力,而消费者的回收知识有限、政府回收政策失效和投融资规模小是系统恢复力缺失的主要原因;(4)废弃物供需不匹配和消费者的回收知识有限属于随动因素,需要从其引致因素入手,采取有针对性的治理策略。因此,本文从这六个关键影响因素入手,提出削减系统脆弱性的政策建议,为促进城市废弃物资源化利用网络稳固升级提供决策依据。
[Abstract]:The deepening of vulnerability theory and the development of practice provide a new perspective and direction for the study of urban waste resource utilization. This paper through combing the domestic and foreign literature from the urban waste recycling network supply. Recovery, recycling and marketization of four links extract 24 vulnerability factors and map them to sensitivity. Three dimensions of adaptability and resilience. The DEMATEL-ISM-ANP integration method was established, and the expert questionnaire was used to obtain the data to carry out the empirical research. To analyze the interaction between each group of factors and factors, and calculate the impact strength of each vulnerability factor, and then use the comprehensive index method to carry out vulnerability evaluation. The key influencing factors were identified and the influencing mechanism was discussed. The results showed that the influencing factors of urban waste resource utilization network vulnerability had obvious hierarchical network structure characteristics. The 24 influencing factors can be divided into four types: drive, interaction, follow-up and independence. 2) the vulnerability index, sensitivity index, adaptability index and resilience index of urban waste resource utilization network were 3.351, 3.688, 3.042 and 3.362, respectively. Are in the middle and high level, the urgent need to strengthen regulation and control; 3) the mismatch of waste supply and demand is the key factor that affects the sensitivity of the system. The poor benefit of recycling and the irregular recovery behavior reduce the adaptability of the system, and the consumers' recovery knowledge is limited. The failure of government recovery policy and the small scale of investment and financing are the main reasons for the lack of system resilience. 4) the mismatch of waste supply and demand and the limited recovery knowledge of consumers belong to the following factors, so we need to start with its causes and adopt targeted management strategies. Therefore, this paper starts with the six key influencing factors. The policy suggestion of reducing the vulnerability of the system is put forward to provide the decision basis for promoting the steady upgrading of the urban waste resource utilization network.
