Abstract
Employees' psychosocial competency and CSR participation help them to achieve pro-environmental knowledge for enhancing ethical consumption behaviors. The aim of this study is to assess the level of social responsibility of tourism firms and also examine the impact of environmental knowledge on ethical consumption. The study further investigates the indirect influence through the mediating role of CSR participation and moderating role of psychological social support (PSS) between environmental knowledge and ethical consumption links in tourism firms. This research used quantitative methods and questionnaires for data collection. Data were composed of 387 employees and owners working within tourism firms and hotels. Results demonstrate that environmental knowledge is positively associated with ethical consumption. Findings show that CSR participation mediates the relation between environmental knowledge and ethical consumption. Furthermore, outcomes reveal that psychological social support acts as a moderator between environmental knowledge and ethical consumption. The know-how of employees is dependent on their environmental knowledge and CSR participation. By addressing the mediating mechanism of CSR participation and the interplay of psychological social support, our study adds several insights to the prior literature streams about ethical consumption. As a result of CSR programs, residents become more familiar with ecological protection and more concerned about ethical consumption patterns and develop a sense of responsibility for the environment. Therefore, we recommended that firms should launch CSR programs to increase pro-environmental awareness of consumers and encourage their ethical consumption actions.
