The Korean government is implementing innovative growth policies such as not only a super-connected intelligence project, smart city, smart factories for innovative SMEs, and start-up ecosystem projects, but also policies to innovate regulations and create an innovative infrastructure. The purpose of this study is to suggest the policy implications for the Korean government by analyzing innovative growth policies of major countries such as the United States, Germany, France, and Japan. Against this backdrop, this study focused on a comparative analysis of fourth industrial revolution areas currently being pursued by the Korean government: smart factories, start-up ecosystem, and the fintech industry.
