摘要
本文以大连滨海旅游资源为例,采用二分选择模型条件评价法(CVM)评价海水和沙滩质量改善的经济价值,探索滨海旅游资源生态补偿的价值。研究发现采用Logit二分选择模型估算旅游者意愿支付(WTP)比采用Probit模型更适合滨海旅游资源经济价值评价;在计算WTP的均值解时,采用线性效用差函数更为简单实用。将该方法用于大连旅游景区海水和沙滩质量价值评价的研究,结果表明:采用Logit和Probit模型能够得到一致的WTP;文中采用单解释变量模型可以反应多个解释变量模型的计算结果;测算得到海水沙滩质量改善的非使用价值为215元/人,进而对旅游或环境资源的保护和可持续利用可以有更明确的定量认识。这种经济价值研究方法与过程对探索滨海旅游资源生态补偿的定性研究具有重要意义。
In this paper, we valued seawater and sand quality in Dalian beach area using the contingent valuation method (CVM) of dichotomous choice models, and explored the values of coastal tourism resources Eco-compensation. The researches indicate that it is more appropriate to use Logit dichotomous choice model for estimating tourists' willingness to pay (WTP) than using Probit model under discrete CVM. In calculating the mean value of WTP, it is more simplistic to apply a linear utility difference model. This model directly utilized to measure the economic value of Dalian coastal park seawater and sand quality. The results revealed that: (a) a consistent result was achieved in WTP measurement using both Logit and Probit dichotomous choice models; (b) using a single explanatory variable could generate the same results as using multiple explanatory variable model; (c) the estimated non-use value of the beach quality in Dalian coastal park is 215 RMB per person, and based on the result, sustainable protection and development of tourism or environmental resources may be much clear quantitative recognition. Prospected from the approach and procedure, it is significant to quantitatively study Eco-compensation of coastal tourism resources.
