Abstract:The Maker movement in America has led a worldwide wave of mass innovation in a short period of time, but its value and function is rarely discussed from the perspec-tive of science and technology innovation in academic circle. Based on the theories related to scientific and technological innovation, this paper systematically analyzes the historical evolution and functional deduction of the Maker movement in Ameri-ca, reveals its potential value and deconstructs its national metaphor of publicizing mass innovation, aiming to provide reference inspiration for the high-quality devel-opment of mass entrepreneurship and innovation in China (hereinafter referred to as “Double Innovation”). Analysis shows that, Maker movement in America has gone through three stages of development: garage DIY, hacker revolution, and “Grass-roots” innovation. It clearly shows an evolutionary path from closed innovation to open innovation and then to mass innovation, thus creating a new innovation para-digm with grassroots characteristics. By embedding the national innovation strategy, constructing an open-source ecosystem for reshaping the innovation value system, expanding the symbiotic boundary of regional innovation networks, enabling science and engineering workforce development, the Maker movement in America has cre-ated an engine of innovation for the national innovation ecosystem, which is beyond the scope of the whole society's mass action on innovation, and even carries the im-portant mission for promoting the national innovation strategy. Drawing on the de-velopment experience of Maker movement in America, we can speed up the high-quality development of innovation and entrepreneurship in China from three aspects: cultivating open-source innovation ecosystem, strengthening the construc-tion of innovation space, and constructing innovative talent training system.
