基于Grey-DEMATEL的城市废弃木家具回收障碍因素分析

Analysis of Restrictive Factors of Urban Waste Wood Furniture Recycling Based on Grey-DEMATEL

近年来,我国城市环境污染逐渐凸显,生活垃圾产生量逐年上升,特别是废弃木家具等大件垃圾污染,影响市容市貌,是城市生态文明建设必须要解决的一大难点问题。通过对现阶段城市废弃木家具回收处理现状进行调查,在此基础上结合文献阅读总结,构建了政府、家具制造企业、非正规回收商和居民四个层面的障碍因素体系,运用灰色-决策跟踪与评估实验室方法(Grey-DEMATEL)进行计算。研究结果表明,政府相关因素是促进城市废弃木家具回收中重要的原因因素,居民相关因素是重要的结果因素,在短期内解决可以获得较好的效果,与家具制造企业相关的因素中心度大,对城市废弃木家具回收的作用很明显,需要重点考虑。

Based on an investigation of the current situation of the recycling and treatment of urban waste wood furniture,and in combination with literature reviewing,we established the corresponding restrictive factor system at the four levels of government,furniture manufacturing enterprise,informal recycler and resident,and used the grey-DEMATEL method for calculation.The result showed that government was an important attributing factor to improving the urban recycling of the waste wood furniture;resident was an important outcome factor,the speedy resolution of which could yield good effect;while the factor of furniture manufacturing enterprise was of significant centrality,which should be prioritized since it had obvious impact on the urban recycling of the waste wood furniture.
