This paper aims to explore the impact of Information and Communication Technologies (ICT) on labor productivity growth in Turkish manufacturing. This is the first attempt at exploring the impact of ICT on productivity in Turkish manufacturing at the firm level. The analysis is based on firm level data obtained from Turkish Statistical Institute (TURKSTAT) and covers the period from 2003 to 2012. The data used in the analysis includes all firms employing 19+ workers in Turkish manufacturing industry. Growth accounting results show that the contributions of conventional and ICT capital to value added growth are not significantly different from each other. On the other hand, results based both on static (fixed-effects) and dynamic panel data analysis highlight the positive influence on firms' productivity exerted by ICT capital. The findings show that the impact of ICT capital on productivity is larger by about 25 to 50% than that of conventional capital. This contribution of ICT capital is higher than that of non-ICT capital for small sized and low-tech firms. Our findings imply that investing in ICT capital increases firm productivity by increasing the productivity of labor and also that convention growth accounting approaches may not be adequate to identify such linkages.
