This study: (1) characterises technological change in both advanced & developing worlds and assesses the technology climate of a case country (ie, Bangladesh) & her catching up efforts towards technological mastery; (2) spots aggravating conceptual confusions among some purpose-built short-cut schemes to advanced technology transfers, eg, EPZs, Industrial Parks, Technology Parks, etc.; (3) makes specific queries about the nature & operational features of these schemes and proposes an unambiguous conceptual framework of a standard model, namely, 'special technology infrastructure' (STI) classifying the schemes in terms of their business, research & technological orientations; (4) conducts performance appraisals of the technological 'catching up' efforts in Bangladesh-EPZs using secondary data & in Dhaka-EPZ using a mix of primary & secondary information. (5) draws particular attention to the significance of the concept of 'dated labor' (workers with the latest know-whys) from 'vintage growth model', and pinpoints the importance of ensuring the presence of a technologically capable workforce prior to utilizing the zone concepts for technological learning & mastery.
