AN INDIVIDUAL TRAVEL‐COST METHOD OF EVALUATING FOREST RECREATION
用传统分区法和个体观察法两种旅行费用法估算森林游客的消费者剩余，发现两者结果差异很大，对林业游憩价值评估和投资回报率计算有重要影响。
Consumer surplus for outdoor recreation has traditionally been estimated by a Clawson‐Knetsch travel‐cost method. This paper presents zonal consumer‐surplus estimates for visitors to a number of forests and compares these estimates to those derived from individual visitor observations. Both travel‐cost procedures are used to assess the magnitude of recreational benefits and are found to produce widely different consumer‐surplus estimates. This raises questions about research methodology and has implications for the value of recreation associated with forestry and its contribution to the rate of return on forest investment.
