Research On“Extend And Raise” Service In Crowdsourcing Contests

This paper focuses on the “Raise and Extension” service on Internet crowdsourcing platforms which hold innovation contests for companies seeking solutions to their problems. The main purpose is to analyze the effects of this service and to investigate the factors that influence the seekers’ decision to adopt this service.By collecting and analyzing real business data from a Chinese Witkey website Taskcn.com, it is found that adopting this service leads to a higher number of proposals, but it doesn’t help to attract higher level solvers. Besides, this research also finds out that the more difficult the task and the more open the submitted proposals, the more likely the seeker adopts this service.This paper contributes to both the theory as well as managerial practice. On one hand, this research provides new perspectives for the future research, since there is little research on this kind of services. On the other hand, the participants can optimize their strategies by referring to our results.
