Abstract: Aiming to report the perception of what drives the development of PPPs in China from the perspective of public sector， a structured questionnaire survey was conducted by focusing on 15 identified driving factors. 5 most important public sectors' purposes to adopt PPP are obtained according to the factor analysis built on the survey results. Appropriate understanding of important driving factors will provide a more informed basis for Chinese government and private sectors to make decision and collaborate through long term contractual arrangement to achieve value for money.
Key words: public private partnerships; positive driving factors; questionnaire survey; factor analysis
