The data of questionnaires investigation was analyzed using methodology of independent means T-test and one-way ANOVA. The above methodology was applied to test the differences in total travel cost according to visitor’s identity. The recreation benefit of Kenting Nanwann beach was also estimated by travel cost method. The trip demand function was constructed by different count data models, namely, Truncated Poisson (TPOIS), Truncated Negative Binomial (TNB) and On-Site Poisson.
This study has found that the most appropriate model was the On-Site Poisson to estimate recreation benefit of Kenting Nanwann beach. The price elasticity of demand and income elasticity of demand were -0.2385 and 0.1193. The average consumer surplus (CS) under TPOIS model, TNB model, and On-Site Poisson model were NT$ 32154, 32258, 27397, respectively. The results of this research indicated that CS under TNB model was the highest, and under On-Site Poisson model was the lowest. The recreation benefits estimated by the different indices (CS, CV, and EV) in the same count data model were not significantly different. The reason was that the effect of income was not significant in the trip demand function. Because the different indices (CS, CV, and EV) in the same count data model were not significantly different, the CS was applied to the estimating of the recreation economic benefits. The recreation economic benefits were NT$ 8.22 billion calculated from TPOIS model, NT$ 8.25 billion calculated from TNB model, and NT$ 7.0 billion calculated from On-Site Poisson model.
The values of willingness to pay of Kenting Nanwann beach were also calculated as follows: option value was NT$ 82.2 per-year per-person, existence value was NT$ 95.8 per-year per-person, and bequest value was NT$ 101.4 per-year per-person. The total recreation economic benefits were NT$ 71 million by contingent valuation method.
