La relazione tra input ed output innovativi nell' industria italiana

Andrea Conte ()

Rivista di Politica Economica, 2005, vol. 95, issue 4, 129-160

Abstract: This paper provides new evidence on the determinants of innovation at the firm level. Empirical results are obtained through different and comparable econometric estimates; the Knowledge Production Function (Griliches, 1979) is the theoretical basis for this approach. Data are obtained from the second Community Innovation Survey (CIS) for the years 1994-1996 with respect to the Italian industrial sectors. Results show the existence of different causality relations between innovative inputs and outputs. Specifically, Cragg's test (1971) indicates that a firm's innovation probability and its share of innovative turnover do not depend on the same set of variables. Moreover, there are complementary effects between innovative inputs while the distinction of the innovative process in different phases is empirically verified (Kline and Rosenberg, 1986).
