Implementation constraints in public-private partnership : Empirical comparison between developing and developed economies/countries

Purpose This paper aims to empirically investigate the differences and similarities on the implementation constraints in public–private partnership (PPP) in developing and developed economies/countries, represented by Ghana and Hong Kong, respectively. Design/methodology/approach A questionnaire survey was conducted with relevant experienced PPP practitioners in Ghana and Hong Kong. One hundred and three completed questionnaires were received for analysis. Kendall’s coefficient of concordance analysis, mean score ranking, Mann–Whitney U test and quartile grouping were used for data analysis. Findings The results show six implementation constraints with significant differences. Constraints related to the general investment climate of PPP projects (i.e. ecological conditions of PPP) are ranked higher in Ghana than in Hong Kong, whereas constraints related to the organisation and negotiations of PPP projects are higher in Hong Kong than in Ghana. Further, two constraints, lengthy delay in finalising negotiations and lengthy delay due to political debate, are very critical in both jurisdictions, whereas “negative public perceptions on PPP transactions” and “high use of unsolicited proposals” are of less challenge in the implementation of PPP in both jurisdictions. Originality/value The findings of this study contribute to knowledge on the international best practices of PPP. In addition, international private bidders would be informed of the mitigation measures to adopt when engaging in PPP arrangements in any part of the world, whether in a developing or developed economy country.
