Purpose: The purpose of this study is to explore the motivations of governments for adopting unsolicited proposals for public–private partnership (PPP) project implementation. Design/methodology/approach: A comprehensive review of literature was conducted to derive a list of motivations for adopting unsolicited PPPs. Subsequently, an empirical questionnaire survey was conducted with international PPP experts. Inter-rater agreement analysis, mean significance index and independent two-sample t-test were used for data analysis. Findings: Results reveal four very critical motivations for governments’ interest in unsolicited PPPs; these include: “enhanced private sector innovation and creativity in PPPs”; “lack of public sector capacity to identify, prioritise and procure projects”; “lack of private investors’/developers’ interest in projects at remote areas”; and “rapid implementation of PPP projects”. Further analysis shows that developing and developed countries view the significance of three motivations differently. Research limitations/implications: The major limitation lies in the fact that this study only focused on the general motivations/rationale for using unsolicited PPP proposals and did not thoroughly examine and consider the inherent property of motivations (i.e. push and pull theories). Therefore, future studies should explore the “pull and push” motivations for adopting unsolicited PPPs within a specific country or region. Originality/value: The research outputs inform international private developers of the key expectations of governments/public departments when submitting unsolicited PPP proposals for consideration by the public sector. Furthermore, the outputs will enable governments/public departments and private proponents to derive performance objectives and standards for unsolicited PPP projects.
