註釋We examine the impact of labour productivity growth of small and medium-sized enterprises (SMEs) on labour productivity growth of large firms in a 19-year panel of 26 European countries. We apply a dynamic panel data model that allows for macro-level interdependencies in productivity between small and large firms. Our main finding concerns a sizable positive effect of labour productivity increases of SMEs on the productivity of large firms. This positive effect is especially evident for medium-sized and small firms (rather than micro firms). Furthermore, the impact of SME productivity on large-firm productivity is increasing with the size of the SME sector. Our analysis indicates that scale effects play a role in the transmission of productivity effects from SMEs to large firms, both in terms of the size of individual SMEs (medium-sized and small versus micro) and in terms of the share of the SME sector in the economy.
