Total Factor Productivity Contributions and Its Drivers: Endogenous Growth Accounting Approach

This paper applies the endogenous growth accounting Approach to measure total factor productivity (TFP) and its Contributions in ۱۲۱ four-digit ISIC code manufacturing industries between ۲۰۰۳ and ۲۰۱۹. The basic problem of most researchers is that they use the theory of exogenous growth to account for. This study uses the endogenous growth theory and the induced innovation theory to justify the utilization of varying coefficient production functions and decomposes total factor productivity into two parts: input-embedded and input-free productivities. Input-free productivity is divided into technical efficiency change and technological progress, while input-embedded productivity depends on the inputs used in the production function (labor and capital). Findings show that the average value-added growth is % ۶.۷%. The average ratio of input-embedded productivity in the industry's growth is about ۲۱.۸%. The contribution of capital-embedded productivity is -۶.۷%, and the contribution of labor-embedded productivity is ۲۸.۵%. Therefore, technology is more manifest in labor. The IFP-free productivity ratio is ۱.۴%, which is due to two factors: technical efficiency change and technological progress.
