Government’s motives and investor’s commitment in public-private partnership procurement system adoption

The study examined the government’s motives in adopting public–private procurement (PPP) and its relationship with the private investor’s service commitment to infrastructure delivery. The study adopted a quantitative research method with a survey conducted using a structured questionnaire targeted at 384 respondents selected through random sampling. The data were analysed using mean, percentile and Pearson correlation statistical tools. The study identified 17 key motives responsible for the government adopting PPP in socio-economic infrastructure delivery. These motives were factored into three main groups: public infrastructure maintenance, financial and economic benefits; improved discipline in the contractual relationship and predictable path in infrastructure delivery and integration of innovative approach in enhancing infrastructure delivery. Therefore, the relationships between the three factored government’s motives and investor’s commitments, including finance, management, technical and operational services in PPP, were tested using the Pearson correlation statistical tool. The results showed that the motive for public infrastructure maintenance, financial and economic benefits of the government in PPP showed a significant relationship with the four services commitment of private partners. Also, the government’s motive for improved discipline in the contractual relationship and predictable path in infrastructure delivery showed significant relationships with technical, finance and management commitments of investors. Lastly, the government’s motive for the integration of innovative approaches in enhancing infrastructure delivery showed a significant relationship with only technical commitment. The outcome indicates that factors measuring government motive and investor's services commitment are mutually dependent and critical in ensuring a sustained relationship among stakeholders in a PPP arrangement for infrastructure procurement.
