Abstract: Highway construction requires a large number of long-term capital investment, only the government's financial funds and vehicle purchase tax revenue is far from enough. It is therefore necessary to encourage the private sector to join and form a multi-level public infrastructure capital supply framework. For highway projects whether to use public-private partnerships (PPP), although China has issued a "PPP value evaluation guidelines (Trial)", but the lack of flexibility and operability. This paper establishes the Value for money (VfM) evaluation model and makes empirical research through the actual highway project, so as to make quantitative decision on whether the highway project adopts the PPP.
