INVENTION, INNOVATION SYSTEMS, AND THE FOURTH

This article reviews the interplay of major and changes to innovation systems during three historical industrial revolutions as the basis for understanding whether a new era is underway at present. The periods start with widespread use of steam power and using from the 1850s onwards; , synthetic materials, and beginning in 1900; digital computing and electronic starting in the 1960s; and a potentially emerging fourth revolution of arti- ficial intelligence and distributed small-scale manufacturing. Specific inventions, changes to national innovation systems, shifts in workplaces and the organization of labor, and evolving styles of consumption are considered for each of the discrete industrial eras. The article con- cludes with lessons about spillovers from innovation that underpin industrial revolutions and offers perspective on contemporary debates concerning the rate of change. It also suggests that organizational and institutional structures that support inventors and ensure returns to corporate innovation in the will need to adjust if a fourth industrial revolution has begun.
