Abstract
Stakeholders of PPP projects may induce opportunistic behaviors in long-term cooperation. Existing studies emphasized the inhibitory effect of trust on opportunistic behaviors, but most of them simplified the trust relationship into a two-subject perspective. From the perspective of social network analysis, this research constructs a network-level trust relationship between the stakeholders of PPP projects. The index analysis of the trust network shows that the PPP project stakeholders have obvious centrality and there are structural holes in the networks. From the perspective of the stakeholder alliance, different forms of alliances differ in the degree, betweenness, and closeness centrality of the trust network. On this basis, the analysis results of different trust network indicators match the corresponding preventive measures of opportunistic behavior, and this research provides comprehensive suggestions for project management.
Highlights
Construction projects using the public-private partnership (PPP) model can be regarded as a long-term social network structure [1]
43.84 binary trust relationship is vulnerable to the influence of other stakeholders, which conforms to the actual situation of the rail transit PPP project. e degree centralization is obviously greater than the degree centralization, which indicates that the direction and intensity of the trust relationship are unbalanced among the subjects. e betweenness centralization indicates that only 23.46% of the stakeholders can effectively deliver trust in the trust network
Financial institution, engineering consulting company, exploration and design company, and implementing institutions rank high in the order of point degree and center degree, indicating that they can be trusted by more stakeholders in the trust network of PPP project competitive bidding stage
Summary
Construction projects using the public-private partnership (PPP) model can be regarded as a long-term social network structure [1]. If the trust relationship between project stakeholders is shallow, opportunistic behaviors are more likely to occur [5]. Identifying weaknesses in the network indicates that opportunistic behavior is likely to occur [10]. On this basis, when different forms of stakeholder alliance are concluded, the model structure and indicators of the trust network change. By comparing the trust network density, centrality, and other indicators of each model horizontally, the enhancement or the weakening of the trust relationship in the social network can be determined, which reflects the reduction or the enhancement of the possibility of opportunistic behavior [7, 11], and management suggestions or prevention programs can be proposed on this basis
