The document discusses how countries can maximize economic growth through adoption of the Industrial Internet of Things (IIoT). It finds that IIoT could add $10.6 trillion to global GDP by 2030 under current conditions, and $14.2 trillion with additional investment and policy support. Countries' ability to "absorb" IIoT innovations, known as national absorptive capacity (NAC), will influence their economic gains. The document provides recommendations for countries to strengthen NAC and fully realize IIoT's growth potential.
