In the era of the digital economy, digital platforms are an important engine to promote the high-quality development of China’s economy. As a firm capability to build or use digital platforms to gain competitive advantages, digital platform capability has become the focus of practice and theory. Although a large number of researches have been conducted about digital platform capability, related researches are relatively scattered and have not yet formed a systematic framework. In view of the fact that empirical literature can provide the latest research results and effectively reflect the development trend of a certain field, this paper systematically reviews the empirical literature on digital platform capability. Firstly, the theoretical foundations of the empirical research on digital platform capability are reviewed. Secondly, the empirical research methods are reviewed. Thirdly, the specific research content is reviewed from the four aspects of connotations, antecedents, outcomes, and boundary conditions of digital platform capability, and on this basis, an integrating research framework of digital platform capability is constructed. Based on the shortcomings of existing researches, four directions worth paying attention to in future research are proposed: multiple theories; multiple research methods; integration of theory and research methods; antecedents, consequences, and boundary conditions at different levels. This paper systematically presents the research status of digital platform capability and provides ideas and inspiration for scholars who intend to conduct researches about digital platform capability.
