Social innovation is slowly spreading to virtually every sector of the global economy, according to the Stanford Social Innovation Review’s summer issue.One unusual article comes from Seoul’s mayor, Won-Soon Park, who has worked in the nonprofit, private and public sectors. He claims that the melding of these sectors is the natural result of technology, which has blended the different sectors of modern society: As we become increasingly interdependent, the once-rigid boundaries between the public sector, private sector, and civil society are being challenged—each sector pursues innovation and convergence. One example of this interconnectedness is a social investment fund the city of Seoul created in partnership with local businesses. Park’s government also lets its citizens direct $47 million in public funds through participatory budgeting, transforming a civil society previously defined by military oppression into one of open civic participation.
