“…These dyadic relationships may be through linkages with foreign firms in the form of licensing agreements, joint ventures, technology cooperation, technical assistance, strategic alliances, and other forms of commercial inter-firm relationships that transcend the local economy. By facilitating the acquisition, assimilation, and possible improvement of foreign technologies, such transnational inter-firm linkages may comprise important sources of "learning by interacting" with foreign, more technologically advanced partners (Amsden, 1989;Hobday, 1995;Mathews, 2006). Another source of externally mediated inter-firm learning may take place when firms interact with local competitors either through formalised ventures, such as project partnering, or from non-formal channels such as "learning by imitation and copying" and local labour turnover.…”
