An important segment, tourism e-commerce live streaming (TEcLS) has emerged as a new marketing channel actively embraced by destination marketing organizations (DMO) and tourist firms due to the COVID-19 pandemic. China, Japan, Australia, and many other nations have been selling such tourism products on various platforms. Live e-commerce generates a real-time interactive virtual environment that can be called a livescape. However, many tourism destinations or companies are unaware of the marketing science implications of live streaming and are unsure of their effectiveness or the intricacies of marketing live streaming. Previous research has explored the factors influencing consumer purchase behavior from the product, technology, and live-streamer perspectives, arguing that the advantages of breaking through time and space constraints, strong interactivity, the experience of reality, technological ease of use and usefulness, and celebrity aura encourage online purchases. However, limited investigation has been carried out on the impact of customers’ value-co-creation in livescape when watching tourism live streaming on their purchase intentions considering the key role of engagement. This calls for specific investigation of the phenomenon to facilitate live streaming design and tourism marketing. This study aims to explores the factors influencing consumer purchase intentions in the livescape based on a value co-creation research framework. Compared to traditional e-commerce, livescapes provides the “many-to-many” social presence and an immersive value co-creation platform. Thus, we focus on why and how social presence inspires customer engagement, ultimately leading to purchase intentions. This study finds that, as a crucial marketing tool, the social presence of tourism livescapes can promotes customer engagement, which in turn results in intentions to purchase tourism live-streaming products. Additionally, the mediating role of inspiration (inspired-by and inspired-to) between social presence and customer engagement is examined to reveal the influence mechanism in the tourism context. Finally, this study examines how to create an effective tourism livescape to enhance tourists social presence experience and inspire their engagement, which in turn increases their purchase intention.
