“…Then, considering the most important value item as a score of 100, we asked respondents to assign relative scores to the remaining value items. Finally, using these scores, the relative importance (weight) of the value item j (RI j ) can be calculated using the average score of each value item (score), as shown in Equation (5).…”

“…However, because of the nature of the water supply, losses from these accidents include not only the cost of restoration but also those from damages that arise during the restoration period. For instance, households may incur inconvenience costs from being unable to use water [1-3] and industrial or commercial facilities may face substantial economic losses due to water outages [4,5]. Moreover, various water-related conflicts may arise, and the response capability for emergencies or disasters may decrease [6,7].…”

Parallel pipeline projects can contribute to ensuring a safe and stable water supply and preventing or mitigating losses caused by water pipeline accidents. However, because these projects require a significant investment, feasibility tests are essential prior to their implementation. Considering the public nature of the water supply, the direct beneficiaries of the project and people from other regions can place value on such projects. Thus, this study estimates the value of parallel pipeline projects using the contingent valuation method (CVM) and the swing weighting technique. We constructed two contingent valuation surveys: one asking about the willingness to pay (WTP) for a parallel pipeline project within the respondent’s region and the other asking about the WTP for a project outside the region. The results show that the annual WTP per household for projects within and outside the region was 113,669 KRW (87.98 USD) and 5493 KRW (4.25 USD), respectively. These results indicate that the value perceived by people from outside the region should be considered. Additionally, the results from the swing weighting technique and WTP analysis show that the values that respondents generally consider important and those that can leverage the overall project value are distinct. This study’s results provide insights into the implementation of parallel pipeline projects in South Korea. Furthermore, this study’s analytical framework can be used for the valuation of other public infrastructure projects.

“…If not handled properly, it is likely that the final effect will be contrary to the project objectives and lead to social risks [22]. Based on previous research, the impact of water environmental governance projects on society is mainly reflected in aspects of environmental change, service provision, and corresponding price [23][24][25]; in addition, the safety issue of a project is also considered important [26]. Therefore, this paper summarizes environmental issues, safety issues, service issues, and price issues as four main reasons that trigger social risks, among which service issues and price issues are the problems faced during the operation period.…”

“…Existing research has explored social risks in PPP projects of water environmental governance [22][23][24][25], but there still needs to be further discussions of sources and influencing factors of social risks. This paper establishes the theoretical framework of social risks by combining vulnerability, which deepens the understanding of the influencing mechanism of social risks.…”

The Chinese economy is transitioning from high-speed development to high-quality development, and water environmental governance is a key factor promoting economic transformation. Due to low returns and high investment in China’s water environmental governance, the PPP (public–private-partnership) model is often adopted. However, the PPP model has historically faced challenges adapting to local conditions in China, leading to social risks in the PPP projects of water environmental governance. To reduce these risks, this paper takes a vulnerability perspective, employing the system dynamics simulation method to explore the dynamic evolution process of social risks in the PPP projects of water environmental governance. The main results show the following: (1) the external manifestations of social risks during the construction and operation periods vary significantly, exhibiting notable fluctuations; (2) during the construction period, there is a surge in social risks followed by a returns to lower than normal levels, then a gradual upward trend; during the operation period, social risks initially decrease to a lower level before gradually increasing; and (3) city class, relevant legal systems, and resource reserves emerge as critical factors influencing vulnerability and social risks. The higher the city class, the lower the project vulnerability; the soundness of the legal system for PPP projects can effectively reduce vulnerability and social risks; sufficient resource reserves can reduce social risks. Based on the above findings, this paper proposes several suggestions aiming to reduce the vulnerability and social risks in PPP projects, optimize the process of water environmental governance, and further promote the sustainable development of water environmental governance and the high-quality economy of China.
