A Study on the Evaluation of the Innovation Efficiency of Star Hotel Services Based on the DEA-Malmquist Index

Based on the panel data of star-rated hotels in China from 2015 to 2021, the following conclusions were drawn by using the DEAMalmquist index method to investigate the eficiency of service innovation of star-rated hotels in China and to analyze the factors that inZuenced the change in the eficiency of star-rated hotels in China [1]. The service innovation eficiency of high-star hotels has a high sensitivity to changes in the external environment, while low-star hotels show a relatively resilient life under the unfavorable external circumstance [2]. Technological progress is an important reason for the promotion of service innovation eficiency, especially the key reason for the improvement of service innovation effciency of high-star hotels [3]. The expansion of enterprise-scale has a more obvious inhibiting effect on the improvement of service innovation effciency of low-star hotels [4]. After the epidemic, pure technical effciency can obviously promote the service innovation effciency.
