Abstract: With the rise of the digital economy,many hotels are looking for new opportunities through digital transformation.Digital transformation dynamic capability plays an important role in hotels in promoting the integration and reconstruction of internal and external resources and accelerating the improvement of digital transformation effectiveness in a dynamic environment.Theoretical research focusing on hotels’ digital transformation dynamic capability has increasingly become the focus of academic circles.From the perspective of dynamic capability theory,this paper took the hotels implementing digital transformation as the object,explored the connotation and structure of hotel dynamic capability under the situation of digital transformation and developed and tested the corresponding scale through the method of combining qualitative research and quantitative research.The results show that the dynamic ability of hotel digital transformation refers to the ability of hotel to have a keen insight into the digital trend and timely adjust and update the corresponding strategy in the context of the digital era,to digitally reconstruct the core elements of the hotel through effective acquisition and integration of digital resources,and ultimately create greater value for both the hotel and customers.This ability is composed of three advanced abilities： digital trend insight,digital resource acquisition and digital integration and reconstruction.Among which,digital trend insight ability includes three aspects：digital environment perception,digital status analysis and digital strategic conception;and digital resources acquisition ability includes three aspects：digital human resource development,digital ecological partner empowerment and digital organization matching.The ability of digital integration and reconstruction includes three aspects：digital process improvement,digital marketing reform and digital product/service innovation.The empirical test proves that the developed scale has good reliability and validity,and the hotel’s dynamic capability in digital transformation situation has a significant positive impact on the hotel performance,and the predictive validity of the scale could also be guaranteed.In general,this study deepened the theoretical research on hotel digital transformation capability and provided an effective measurement tool for subsequent empirical research in this field,as well as reference and guidance for improving the effectiveness of hotel digital transformation.
