Applicability of public-private partnerships in smart infrastructure development: the case of Hong Kong

Revamping infrastructure development with the best-emerging technologies and innovative procurement initiatives is seen as the optimal way forward to sustainable development, improved safety and health, performance and management of built infrastructure. The global COVID-19 pandemic has amplified these imperatives highlighting the global need for 'smart infrastructure'. The needs for overcoming resource constraints suggest the increased potential for Public-Private Partnership (PPP) procurement strategy worldwide. Thus, this study aims to assess the potential for successful partnering between the public and private sectors in developing and sustaining 'smart infrastructure' in Hong Kong (HK). A qualitative research design was adopted, leading to ten expert interviews after a comprehensive literature review. The findings unearthed the potential enablers, barriers and enhancing factors, which were built upon regulatory, social, technical and political factors, affecting the adoption and success of PPP in delivering smart infrastructure in HK. An indicative framework was developed to illustrate the fundamental causal relationships of these factors. Through the findings, managing stakeholders, citizen-centric approach and maintaining transparency throughout the project, were identified as significant for the success. The research findings facilitate further studies along with pilot-applications of better-informed approaches to derive enhanced perceived benefits from PPP under appropriate conditions for smart infrastructure in HK.
