“…How imitation, innovation, and productivity are related is discussed mainly on a theoretical level. Most previous works are formal models (Aghion et al, 2001;Vandenbussche et al, 2006;Benhabib et al, 2014;Chang et al, 2015, König et al, 2016. Empirical studies are few and mainly limited to country-level analysis (Vandenbussche et al, 2006;Madsen et al, 2010) and case studies of firms in certain industries, such as the telecommunications industry (Lee and Lim, 2001;Guo et al, 2015), the electronics industry (Hobday, 1995;Kim, 1997;Lee and Lim, 2001), and the automobile industry (Lee and Lim, 2001).…”
