Examination Of Factors Influence Public Acceptance Of Waste Lncinerator Sites Based On Structural Equation Modeling

The municipal waste problem has become an urgent environmental protectionissue to be resolved. Because of the economic development, and scarce land resourcesin city and the inprovement of public's environmental protection consciousness, sitingselection of waste incineration plant has become the focus in the whole society. Theempirical research on waste incinerator site selection was done from the view ofpublic acceptance.This paper summarized the basic theory and the research status of publicacceptance firstly, and the affecting factors of location selection were summarized andanalyzed. Then it introduced Structure Equation Modeling (SEM), including relevanttheoretical knowledge and modeling steps, screening significant influence factors inthe existing research, and combining with the spot investigation to get influencefactors, the causal relationship on the basis of the existing hypothesis, to set an initialmodel in our research. Panyu district in Guangzhou city was choosed as the empiricalresearch place. Through estimating the model parameters, evaluating and correctingthe model, and finally determined the significant index of the external measuredvariables to public acceptance, and concluding the more perfect structure equationmodeling. According to influence the public acceptance of the significant factor, it putforward the advice about improving public acceptance of waste lncineration plantlocation and trust.The paper was sum up by the outcomes as followed.(1) On the foundation of the previous literatures, On-the-spot investigation andexpert consultation program, we design out the questionnaire. Using the softwareSPSS17.0to exploratory analysis the questionnaire samples data, and concludes thatthe acceptance influence factors of waste lncineration plant location are perceivedusefulness, risk perception, compensation rationality, trust etc. The factors for trust arethe principle of site selection and matching management.(2) According to the result of analysis of influence factors, Lisrel model had beenselected to build a suppose model about the public acceptability and trust level. Themodel had been finally comformed after set up, identification and evaluation, the built of related coefficient, test and modified. Software Lisrel8.70was taken to analysisthe data from questionnaire investigation. The results showed that risk perception hadsignificant negative influence on acceptability while the compensation rationality andtrust level had significant positive effects. The related coefficients were-0.68,0.55and0.85, respectively. The T-value didn't reach the significant level although therelated coefficient of perceived usefulness was0.22. Thus, we couldn't make aconclusion that perceived usefulness had significant positive effect on acceptancedegree.(3) The conclusion of all the research was summaried. The author put forward theadivise and countermeasures for improving the public acceptance and trust level ofwaste incineration siting selection. The government and some related departmentsshould make the matching management perfect in siting selection, in order toimporving public trust, and strengthen the principle of site selection to avoid the risk,and give some compensation for the near residents.
