As the great power to drive human society's development and the industrial transformation,disruptive technologies have attracted the attention of countries around the world.The major economies worldwide have made relevant strategic plans to develop disruptive technologies for preempting the zenith of technological innovation.As the effective approach to gather various resources,the multiple input system of disruptive technologies has become a place of strategic importance and related studies have also been paid more and more attention.The multiple input system of disruptive technologies is investigated firstly from the perspective of innovation mechanism in this study.Based on the innovation theory,the technical innovation process and the characteristics of disruptive technologies are systematically analyzed to define the multiple input system connotation of disruptive technologies and to build the research framework.Then various case studies are used to analyze input practices during the innovation process for filling the framework.With the research framework from technical innovation theory and case studies,the multiple input system of disruptive technologies is constructed from innovation mechanism to innovation practice.
