为了保护珊瑚礁、海草床和其他海洋栖息地，黑潮沿岸邻国目前正在开展以社区为基础的海洋资源管理，包括渔业法规、非法捕鱼禁令和建立海洋保护区。本研究以菲律宾吕宋岛南部比科尔地区的圣米格尔岛保护区为例，采用陈述偏好法对农村村民的资源环境保护价值进行了调查。从我们随机抽取的1035户家庭中，我们采访了来自MPA所在的Sagurong村和邻近的Rawis村的329个样本。我们采用非参数方法来估计平均WTW和WTP值。平均世界贸易总值的货币等价物是平均世界贸易总值的15倍。一种可能的解释是，发展中国家农村的劳动力市场是不完整的，因此村民对金钱的偏好比对时间的偏好更强烈，与WTW的货币价值相比，他们表达的WTP可能太少了。这两个村庄的总垃圾价值相当于每天约有100人监视和巡逻海洋保护区。另外，如果按照目前巡警组的每月奖金计算，泗龟荣地区的总WTP相当于43人左右的月奖金。最后，我们估计了志愿者工作和支付行为方程，并检验了指定的影响WTW和WTP的因素的符号方向。在这两个方程中，提出的天数、支付和收入金额等变量的符号与经济理论一致，表明我们的结果具有内在有效性。
In order to conserve the coral reefs, seagrass beds and other marine habitats, neighboring countries along the Kuroshio Current are now carrying out community-based marine resource management, including fishery regulations, illegal fishing bans, and establishment of marine protected areas (MPAs). In this study, we used stated preference techniques to investigate the rural villagers' value of resource and environmental conservation taking the case of the San Miguel Island MPA in Bicol Region, Southern Luzon, Philippines. From the 1,035 households we randomly sampled for our baseline survey, we interviews for this 329 samples from Sagurong village where the MPA is situated, and from the neighboring village Rawis. We applied a non-parametric method to estimate the mean WTW and WTP values. The monetary equivalent of the average WTW is 15 times higher than the average WTP. A possible explanation is that the labor market in rural villages in developing countries is incomplete so villagers have a stronger preference for money than for time and may have expressed their WTP too little as compared with the monetary value of the WTW. The aggregate WTW value for the two villages is equivalent to having about 100 people watch and patrol the MPA per day. On the other hand, the aggregate WTP in Sagurong is equivalent to the monthly incentive of around 43 people if we use the current monthly incentive of the patrol group. Finally, we estimated volunteer work and payment behavior equations, and examined the sign directions of the factors specified to influence WTW and WTP. In both equations, the sign of the variables such as days proposed and amount of payment and income were consistent with economic theory, suggesting the internal validity of our results.
