Chapter 10 Intellectual Property Rights and International Technology Transfer via Trade and Foreign Direct Investment

What roles do trade and foreign direct investment (FDI) play in international technology transfer? Do technologies introduced by multinational firms diffuse to local firms? How does the level of intellectual property rights (IPRs) protection in a country affect its ability to absorb foreign technologies? Using these questions as motivation, this paper surveys the recent trade literature on international technology transfer, paying particular attention to the role of FDI. Several useful conclusions emerge. First, the theoretical literature has shown that trade necessarily encourages growth only if knowledge spillovers are international in scope. Second, existing empirical evidence on the scope of knowledge spillovers (national versus international) is ambiguous. Third, recent empirical plant level studies have called into question earlier studies that argued that FDI has a positive impact on productivity of local firms that compete directly with multinationals. Fourth, there is strong evidence in support of vertical spillovers from FDI: i.e. those firms that either supply multinationals or use goods and services produced by them as intermediate inputs experience productivity gains from such interaction. Fifth, it is well established that the degree of global IPR protection affects the pattern of international trade and convincing evidence that it also influences flows of international technology transfer and FDI has also started to emerge.
