Synergy Degree Evaluation of Stakeholder Engagement in Integrated Municipal Solid Waste Management: A Case Study in Harbin, China.

Municipal solid waste (MSW) has caused the increasing concern for environmental issues in recent years, and the wide engagement from all stakeholders of society has been involved in promoting integrated MSW management. Therefore, this study aims to identify the problems of dis-synergy among multi-stakeholders engaged in the integrated MSW management evolution, then contribute strategies to coordinated development of integrated MSW management system by bettering the engagement and interaction of different stakeholders combined with the region characteristics. From the perspective of the stakeholder theory and synergy theory, we constructed an integrated MSW management system with four stakeholder subsystems: governments, enterprises, residents, and NGO subsystems. We used integrated MSW management in Harbin as a case study and used the synergy degree model to estimate the system synergy degree from 2010 to 2019. Then, the synergetic development trend of integrated MSW management was studied, providing a feasible approach to boost the coordinated development of integrated MSW management in Harbin. The results were in concordance with the factual situation and pointed to integrated MSW management in Harbin and, although there is movement towards a more harmonious and orderly state over time, the government subsystem needs to be further reinforced.
