On-the-job training should therefore be part and parcel of firms' efforts to upgrade their workers' skills. For countries that cannot rely on domestic structures to ensure appropriate skill formation, special economic zones (SEZ) where different trade and incentive regimes are established, may provide appropriate support for on-the-job skills in particular (UNIDO, 2009). Thus, policies dedicated to the establishment of such zones can complement the path towards the productive use of new technologies.
