Mutual growth in the relation between large firms and small-medium enterprises (SMEs) has been an important issue that can be overcome with the concept of open innovation, which is the most continuous research topic in technology innovation. However, most previous studies on open innovation barely analyse both firm types, focusing only on one party. The aim of this study is to develop open innovation models for complementary cooperation between both types of firms in manufacturing industry. Based on a basic understanding of open innovation in each firm type, this study suggests open innovation typology with two main concepts of open innovation: knowledge interaction and technology innovation. Finally, open innovation models are developed, considering the cooperative participants, their relationships in open innovation processes, and open innovation activities illustrated through case studies. The results contribute to manage strategic open innovation between large firms and SMEs through various approaches of cooperation.
