| Summary: | 碩士 === 國立臺灣大學 === 農業經濟學研究所 === 101 === Most studies in the literature implied relationship between distance and willingness to pay is negative, so-called distance decay phenomenon. The purposes of this paper will view an issue from stakeholder perspective and revisit the relationship between distance and willingness to pay. Therefore, conduct a censored quantile regression model for three suitable sets of data to portray the relationship between distance and willingness to pay. One set of data is mainly concerning the users of natural resources as Kenting National Park. As such this set of data can be a representation of user samples. And the other two sets of data are composed majorly by the nonusers of natural resources, i.e. Black -faced Spoonbill Protected Area and Changhua Coast Wetland. These data can thus be a representation of nonuser samples.
The estimate results show that distance and willingness to pay for either user or nonuser samples does have significant effects. While according to the limitation of natural resources for those who reside close to the resource sites, distance and willingness to pay reveals one dimensional positive relation. The closer to the resource site will lead to lower willingness to pay. Residents who live in the local area are more likely to undergo the biggest potential damage of conserving such a site for not allowing their development. Conversely, the farther away from the natural resources site accompanies with the higher willingness to pay. The general public doesn’t undergo the regulatory restrictions of protected area as such their willingness to pay will tend not to decrease, due to their concern for the nonuse or existence value of the site while the natural resources are well protected.
Furthermore, distance elasticity of respondents closer to the site is higher than those farther away from the site. This means, the respondents’ willingness to pay living around the resource site will be more sensitive to the change of distance. As for total values of Kenting National Park, Changhua Coastal Wetland and Black-faced Spoonbill Protected Area are 9.4 billion, 8.2 billion and 5.1 billion respectively. Thus, total values of users are higher than nonusers under the influence of distance.
