摘要:This study examines the relationship between psychological capital, social capital, and adaptive performance in China’s lodging industry. Recent research has revealed that the production attributes of internal social capital can explain adaptive performance, and that psychological capital affects the relationship attributes of social capital. This raises the question of whether social capital might mediate between psychological capital and adaptive performance. Therefore, this study examined data from a sample of 304 hotel employees in China, using internal social capital as a mediating variable. The results confirmed that psychological capital has a significant positive impact on adaptive performance. Social capital also plays a mediating role partially between psychological capital and adaptive performance. The findings of this study contribute to the theoretical framework of psychological capital and adaptive performance and provide a new approach to human resource management in the lodging industry and other dynamically competitive service industries.
