Based on the “Task-Relationship-Change” three-dimensional leadership theory and the grounded theory, this paper deeply explores the connotation and structure of digital leadership. Through completing exploratory factor analysis and confirmatory factor analysis to test the 6 dimensions of digital leadership, this study develops the digital leadership scale that includes 30 items. The dimensions include digital change thinking, digital vision inspiration, digital tool application, digital strategy promotion, digital communication and collaboration, and digital empowerment support. The results of factor analysis indicate that the reliability and validity of the scale are all at an ideal level. Finally, this study tries to test the relationship among digital leadership, knowledge sharing behavior, and creativity.
