A reliable benefit evaluation is highly needed for efficient consolidation of rural parks. This paper aims to analyze relations between willingness-to-pay (WTP) value and visitation frequency by using a gravity model and a contingent valuation (CV) model with consideration of site heterogeneity in the pooled data. The results showed that, (i) the total WTP value decreased in accordance with distance not because of a decreasing tendency in the WTP value itself, but because visitation frequencies were affected by distance, (ii) the WTP value of only visitors corresponded well to the evaluation values by the travel cost method, but the WTP value of all residents did not because the non-use values were evaluated mostly by non-visitors, and (iii) site heterogeneity caused a serious affect on the estimations of the gravity model estimated by reveled preference data, but not in the CV model with stated preference data. From these results, we conclude that the WTP value of the rural park should be estimated with consideration of the residents visitation behavior in order to avoid excess benefits derived from non-visitors and the technique proposed here is useful in the application of the CV method to pooled data.JEL Classification: H43, Q51, Q58, R53
