Research On The Willingness Of Construction Waste Resource Utilization Management From The Perspective Of Contractors

Since the reform and opening up,China's economy has developed rapidly,especially the real estate industry.Under the long-term extensive development mode,the industry led by real estate produces a large number of solid wastes,which brings an irreversible crisis to the environment.Research shows that 40% of solid waste is construction waste,and construction waste can be recycled under certain conditions,which is a misplaced resource.Therefore,the utilization of construction waste resources can effectively avoid excessive waste of resources and achieve the goal of ecological civilization construction in China.At the same time,the recycling of construction waste can also isolate harmful building materials,reduce environmental pollution,transform into a park,and solve the problem of garbage siege.As the main production unit of construction waste,contractors play a leading role in the process of construction waste recycling,and the final behavior of individuals is affected by willingness.Therefore,the study of the willingness of construction waste recycling management can effectively improve the rate of construction waste recycling.Based on the perspective of the contractor,this paper studies the will of the contractor and discusses the factors that affect the willingness of the construction waste resource utilization and management,which is of practical significance.First of all,through reading the domestic and foreign construction waste resource utilization and management related literature,summed up and analyzed the factors that affect the willingness of contractors.Based on the framework of planning behavior theory and technology acceptance model,this paper sorts out the influencing factors,classifies the influencing factors,and discusses the rationality of the factors through on-site investigation and expert interview,and corrects the unreasonable influencing factors.Secondly,it puts forward research hypothesis and builds the final research model.And using the method of questionnaire to study the hypothesis,50 pre questionnaires were issued to verify the rationality of the questionnaire,and then the inaccurate questions were corrected,and then the formal questionnaire was issued.Finally,empirical analysis of the research hypothesis.Through spps20.0 software for preliminary data analysis,and then use amos20.0 software for confirmatory factor analysis,parameter estimation and path analysis,in order to verify whether the hypothesis is true.The empirical analysis results show that the Contractor's willingness to use construction waste resources is mainly affected by perceived usefulness,perceived ease of use and perceived risk.The order of influence is perceived usefulness,perceived risk and perceived ease of use from high to low.The increase of project income in perceived usefulness has the greatest effect on the Contractor's willingness path,while the effect of policy support on the Contractor's willingness path is in perceived usefulness Most of all,the cost of resource in perceived risk has a negative impact on the Contractor's willingness to choose.However,subjective norms and perceived behavior control have no significant effect on behavior intention.
