Abstract:This paper retrieved papers on crowdsourcing by Web of Science, and used knowledge maps method to review the papers in case to analyze the current situation, development trend and current research hotspot in the field of crowdsourcing innovation. The results show that: (1) led by the United States, the western developed countries are the leading countries in this field, China’s research on crowdsourcing innovaton is a bit later than the above nations, though the number of China’s existing research results is at the leading position, it comparatively lacks of high quality works; (2) the research object of crowdsourcing innovation has gradually transformed from crowdsourcing innovation itself to the innovation of enterprise business model, and then to the online knowledge exchange of crowdsourcing community, in addition, the research method is transferred from the classical case analysis into the empirical research method; (3) the hot research areas of crowdsourcing innovation include the content of crowdsourcing innovation, the performance of crowdsourcing, the community platform of crowdsourcing innovation and so on.
