The World Tourism Organization (UNWTO) has constantly promoted sustainable tourism development as well as played an important role since 1980; in addition, numerous standards were regulated accordingly. Under the impacts of both environment protection, energy saving and carbon reduction, the marketing strategy of numerous operators have been changes consequently. The ecological or environment lodging facilities gradually adopted by the people in this trade; nevertheless, there are still not appropriate criteria of green B&B for domestic lodge industry to carry out related strategies. One of the major aims of this study is to establish the criteria of green B&B and index of feasible implementation, and constitute index levels with fuzzy analytic hierarchy process (FAHP), as the major basis of conducting survey of adoption willingness of lodge operator in implementing environment protection strategy. Next, this study intends to explore the current status of environment strategy implemented by B&B manager as well as the factors influence the adoption willingness. Third, find out any other factors and significance that could affect the adoption willingness of B&B manager to carry out strategy. Fourth, this study intends to locate the factors and significance of influencing consumer in accepting environment protection strategy (lodging willingness). There are three research targets employed by the design method of this study, namely, representative experts and scholars in the related domain, for presenting construct index and significance degree; research model establishment of B&B manager, the green B&B index are used for interview and questionnaire survey methods, so as to confirm the aim of this study; and finally the research model establishment of lodge consumer, through hierarchical regression analysis and relevant statistic analysis, to explain significant meaning and reason of variables. The research result proves that green B&B index can be simplifies into eight main dimensions and concrete strategies (management and marketing, social participation and communication, energy management, water resources management, green purchase, solid waste treatment, green restaurant and lodge activities, natural and cultural resources), for reference by verification unit. Secondly, in the research model of B&B manager, environment knowledge behavior would influence the self-efficacy, and further affect the adoption willingness. For operator, the higher the compatibility of environment strategy is, the higher of adoption willingness will be. Finally, in the research model of consumer, the higher the frequency that consumer engaged in the environment related activity, the higher the willingness of selecting green B&B will be; while environment knowledge behavior would affect the perceived caracteristics of innovation, lodge preference, and attitude of engaging in environment activity of consumer. This study defines the implication of promoting green B&B development strategy is ¡§to educate B&B managers attach more importance on environment ethics, and encourage consumer to change the attitude of recreation activity.¡¨ Furthermore, with the conception of simplified green lodge index, to direct towards tourism map planning of ecology village, apart from the unique features of ¡§green B&B¡¨ image, to minimize the impact of recreation environment. By employing innovation diffusion theory (IDT) model in the behavior prediction of environment behavior and tourism behavior strategy, the result of this study could be served as a useful reference for following researches.
