: Evidence for "horizontal spillovers" (benefits to local competitors) is often weak, as multinationals actively guard their technology. However, "backward linkages"—where foreign firms upgrade the capabilities of their local suppliers—show more robust positive effects.
: Developed by Hymer, this posits that firms must possess unique "firm-specific advantages" (e.g., proprietary technology, brand power) to overcome the "liability of foreignness"—the inherent disadvantages of operating in a distant, unfamiliar environment.
: Some research indicates that FDI can "crowd out" domestic investment or lead to a "hollowing out" of local industries if domestic firms cannot compete with efficient multinationals. 3. Practice, Trends, and Challenges
In practice, the landscape for FDI is rapidly shifting due to geopolitical and technological changes.
: John Dunning’s framework suggests FDI occurs when three conditions align: O wnership (proprietary assets), L ocation (host country benefits like low costs or market size), and Internalization (the benefit of keeping operations "in-house" rather than contracting out).
Theories explaining why firms choose to invest directly in foreign markets rather than exporting or licensing can be categorized into four main perspectives:
: Raymond Vernon argued that products go through stages—innovation, maturation, and standardization. As a product matures and production becomes standardized, firms move facilities to lower-cost countries to stay competitive. 2. Empirical Evidence on Economic Impact
The relationship between FDI and economic growth remains a subject of intense debate, often referred to as "empirical ambiguity".
