Technology adoption in developing economies is not automatic. Constraints include lack of absorptive capacity (skills, infrastructure), high costs of complementary inputs, credit constraints, and weak institutions. Learning-by-doing, local adaptation, and gradual diffusion are slower than technology discovery but are how most countries close the technology gap.
From your study of foreign direct investment, you know that capital flows across borders in search of returns. Technology flows the same way — but it travels less freely, and the receiving country's capacity to absorb and use it turns out to matter as much as the technology itself. This is why identical machines produce vastly different outcomes when installed in Singapore versus a low-income country with weak infrastructure and limited technical training. The gap is absorptive capacity: the stock of human capital, institutional quality, infrastructure, and organizational know-how that determines how productively a country can use an imported idea or technique.
Technology transfer refers to the movement of techniques, processes, or knowledge from one country or firm to another. The main channels are FDI (multinational subsidiaries bringing production methods), licensing agreements, imports of capital goods embodying new technology, and skilled labor migration. But transfer is not the same as adoption. A firm might receive blueprints or machinery but lack the engineers to operate it efficiently, the suppliers to provide quality inputs, or the institutions to enforce contracts. Complementary inputs — skilled workers, reliable electricity, enforceable property rights — are frequently the binding constraint. This is why technology adoption is lumpy: it often requires crossing a threshold of complementary capacity before payoffs materialize.
Diffusion describes how a technology spreads through an economy once one firm or sector adopts it. Classic diffusion curves are S-shaped: slow initial uptake as early adopters figure out local adaptations, then rapid spread as knowledge becomes codified and complementary inputs develop, then saturation. The lesson from endogenous growth theory you've already studied is that diffusion is partly a public good problem — knowledge spillovers from early adopters benefit latecomers who didn't bear the adoption costs. This creates underinvestment in adoption and justifies policies that subsidize pioneer firms or build shared infrastructure.
Learning-by-doing is the engine beneath diffusion. Firms and workers who operate a technology accumulate tacit knowledge — practical refinements, workarounds, efficiency gains — that cannot be read from a manual. This tacit knowledge is harder to transfer than formal specifications and must be rebuilt each time adoption occurs in a new context. It also means that local adaptation is not a shortcut: adapting a technology to local conditions (lower-cost inputs, different climate, different consumer preferences) is often necessary for viability, and the firms that do it best tend to capture durable competitive advantages. Countries that can build this adaptive capacity, rather than simply importing final products, are on a faster development path.
The policy implications follow directly. Subsidizing FDI alone is insufficient if absorptive capacity is the binding constraint — the technology arrives but cannot be digested. Investing in education, infrastructure, and institutions expands the absorptive base and raises the return to FDI, creating a virtuous cycle. Export-oriented industrialization strategies work partly because competing in global markets forces local adaptation and accelerates learning-by-doing, compressing what would otherwise be decades of organic diffusion into much shorter timescales.
