The travel cost method (TCM) and the contingent valuation method (CVM) are well-known as the typical technique of environmental economic valuation. The TCM can measure only the direct and current use value of environmental goods, but the CVM can measure the whole value including the non-use value of them. In the business of environmental economic valuation, it is often adopted that the use value is measured by the TCM and that the non-use or the whole values are measured by CVM. However, there is no statistical significance in the difference between those values measured by the TCM and the CVM, because these methods are modeled independently and do not have theoretical consistency. In this study, we have constructed a valuation model based on the CVM consistent with the TCM in order to measure the use and the non-use values of environmental goods consistently. With applying this model to measurement of environmental economic value of Shirakami Mountain Range, practicality of the method is also examined.
