Abstract:Based on the existing research and practice, firstly the concept of "crowdsourcing" is analyzed, and then the difference between crowdsourcing and outsourcing, the difference between crowdsourcing and e-commerce is compared. Finally, the motivation of crowdsourcing participants and the operation mechanism and model of crowdsourcing are analyzed. The results show that: compared with outsourcing, crowdsourcing relies on the innovation potential of social differentiation and diversification, and is not limited by space and distance, so the transaction cost is reduced and the transaction behavior is more free. Compared with e-commerce, crowdsourcing is mainly a non-standard service, which does not require a logistics system, and consumers can also be producers. In addition, the main motivation for crowdsourcing is to obtain external resources and open innovation, and to participate in crowdsourcing by selecting appropriate crowdsourcing models. Crowdsourcing issues can be studied from three different perspectives: participants, organizations and crowdsourcing systems. In short, enterprises can reduce innovation costs and obtain sustainable competitive advantages through crowdsourcing mode. The research content has important theoretical and practical reference significance.
