Most existing studies analyse the early decision‐making processes of public–private partnership (PPP) projects from the perspective of the government or investors, as such decisions involve lengthy negotiations and are likely to lead to unfair results. Hence, there is a need for fair and reasonable investment decision‐making methods. This study investigates the investment return system of PPP wastewater treatment projects. The net present value of investment income is considered the investment decision indicator of social capital, while value for money (VFM) is the indicator of government decision‐making. Considering both yield and VFM, the system dynamics method and Vensim software are used to establish the investment decision model. A case study validates the proposed model and predicts a reasonable range of unit prices and concession periods for wastewater treatment through government–enterprise cooperation, to improve the transparency and initial decision fairness of PPP sewage treatment projects.

Carbon peaking and carbon neutrality goals have proposed by many countries, including China. Meanwhile, China has also proposed the construction of a new-type electric power system with new energy as the main body, which will have great impacts on coal-fired power generation enterprises. The transformation of coal-fired power enterprises is imperative, and the evaluation of the organizational performance of coal-fired power enterprises is urgent, which can accurately determine the development status and even can find issues related to the transformation of coal-fired power enterprises. In this paper, a hybrid evaluation model is proposed based on the Variational Auto-Encoder algorithm and fuzzy comprehensive evaluation method improved by a vague set to comprehensively evaluate the organizational performance of coal-fired power enterprises. Eight coal-fired power enterprises in North China are selected for empirical analysis. The results show that the YC coal-fired power enterprise has the best organizational performance, while the NK coal-fired power enterprise has the worst organizational performance. Moreover, sensitivity and comparative analyses are carried out to verify the robustness of the evaluation result using the proposed hybrid method in this paper. This paper focuses on the organizational performance evaluation of coal-fired power enterprises, which can provide a reference for the smooth transformation and sustainable development of coal-fired power enterprises in the context of “Dual-Carbon” goals.
