Shared growth has become a very hot issue today in Korean society. Since the first proposition in 2006, Korean government has been dedicated in promoting shared growth by launching a series of related policies and regulations. However, despite of all the efforts, a well-known fact is that the shared growth policies and related programs in firms do not sufficiently fulfill the purpose of mutual development and building a sustainable corporate ecosystem. Promoting shared growth in corporate requires a more integrated theory and framework for guidance. This research intended to fill the gap by conducting a case study on one of the representative international firms—LG electronics. By studying LG’s diversified shared growth programs, it proposed a more integrated framework for shared growth and generated valuable implications for bench marking of firms’ shared growth operation, as well as the future directions of government policies. The study was conducted with three steps. Firstly, by conducting thorough review on previous studies, it divided all shared growth related activities into five stages—trust base, competence enhancing, value creating, value sharing, and value diffusion. Second, through the review of internal documents and interviews with employees, it proposed a more integrated framework of share growth which describes interactions between LG electronics and its small business partners at each stage, as well as between stages. At last, it evaluated the achievement of LG electronics in the pursuit of shared growth and proposed future tasks for the development of its sustainable corporate ecosystem.
