International technological spillovers from ICT-producing manufacturing industries: a panel data analysis

摘要

This paper examines the effect of the international diffusion of technological capacity from ICT sectors on the total factor productivity in developed countries. Special attention is paid to the construction of a more recent and homogeneous industry-level data set using unit value ratios and a hedonic price index. A cointegration analysis is performed on this annual panel data for 10 manufacturing sectors in six OECD countries over the period 1979-2001. On the basis of our results, we may conclude that a country receives more international technology spillovers in its manufacturing industries the closer its relations with more technologically advanced nations are and the more open it is to imports. Meanwhile, information and communication technologies developed abroad increase the total factor productivity of each of the manufacturing sectors of a country, and this effect is enhanced where ICT goods are imported from nations with advanced technology of this kind.
