Evidences show that: (i) the relationship between visits and travel cost could be represented more accurately by the public good’s demand curve rather than the private good’s one; (ii) To build the demand curve for such a World Heritage (tourists are inhomogeneous) it requires additional technique to minimize potential distortions, in which the purchasing power parity ratio (PPP ratio) has been used to adjust inconsistence of actual traveling costs; (iii) The values of Hoi An has been valuated at US $ 4,255,724,958 USD in accordance with its public good’s demand curve, shows higher than the value computed according to the private goods’ demand curve.
