摘要:This study proposes an approach based on data envelopment analysis to assess the effectiveness of environmental training for tourists. Most studies have considered only outcomes (i.e., the continuance or halting of improper behavior towards the environment) to represent the effectiveness of environmental training but this approach does not consider the amount of resources that have been applied in the process. The model utilizes input and output factors to estimate the index of effectiveness. We used a survey of underwater tourist activity to test the proposed model in the empirical evaluation and explored both the internal and external influences on the effectiveness.
