Decision-Making Factors Influencing Bundling Strategies in Educational PPP Projects

The continuous expansion of the education infrastructure industry has introduced the Public–Private Partnership (PPP), project bundling in educational PPP is an increasingly mature engineering model in infrastructure construction, but relevant decision-making research is relatively lacking. This study first uses literature research, case analysis, and expert interviews to identify and determine 11 decision-making factors. The meaning of factors is briefly explained. The DEMATEL method was further used to analyze and determine three key factors, namely similarity in project types, project amount, and maturity of preliminary work. There is a synergistic effect of internal functions between different types of projects; a larger number of projects often imply a larger portfolio size; the maturity of preliminary work fully affects the speed of project progress. The impact of factors on bundling projects has been fully explored and analyzed. The research enriches the theoretical knowledge of project management and provides theoretical support for the management optimization of similar projects.
