Bengt-Ake Lundvall

Innovation is not the act of an isolated firm or a linear pipeline from science to market. It is a systemic outcome of the interactions among the actors and institutions of a nation: firms, universities, public research institutes, financial institutions, government agencies, and the education system. The "system" is the set of relationships and institutions that channel and shape the production, diffusion, and use of economically useful knowledge. The boundaries of the system are partly national because institutions, language, tacit norms, and labor markets are nationally bounded. Key work: Lundvall (ed.), *National Systems of Innovation: Towards a Theory of Innovation and Interactive Learning* (1992); Freeman's parallel *Technology Policy and Economic Performance* (1987). Analytical consequence: to explain why one country innovates faster, look at the *configuration of institutions and the quality of interactions*, not just R&D spending.

Lundvall's foundational contribution (his 1985 monograph *Product Innovation and User-Producer Interaction*) is that innovation is driven by the *interaction between producers and users*. Users supply information about needs and performance-in-use that producers cannot generate internally; producers supply information about technological possibilities. Innovation emerges from the iterated exchange across this interface. The quality of these vertical relationships, the trust and shared codes that let tacit knowledge flow, is a primary determinant of innovative performance. Key work: Lundvall (1988), "Innovation as an interactive process: from user-producer interaction to the national system of innovation."

The contemporary economy is best characterized not as a "knowledge economy" (a stock of information) but as a *learning economy*: what matters is the *rate* at which individuals, firms, and regions acquire new competence and discard obsolete competence. Competitiveness depends on learning capability, and the most valuable knowledge (tacit know-how) cannot be codified or bought off the shelf; it must be learned through doing, using, and interacting. Rapid technical change raises the premium on learning and the penalty for those excluded from it, creating a risk of polarization. Key work: Lundvall & Johnson (1994), "The Learning Economy"; Lundvall (2016), *The Learning Economy and the Economics of Hope*.

Lundvall (with Jensen, Johnson, Lorenz) distinguishes two modes of learning. **STI** (Science, Technology, Innovation) is the codified, analytical, R&D-and-publication mode. **DUI** (Doing, Using, Interacting) is the experience-based, tacit, on-the-job, learning-by-interacting mode. Firms that combine both modes innovate most. Policy that funds only STI (papers, patents, lab science) while neglecting DUI (apprenticeship, organizational learning, user feedback, labor mobility) builds an unbalanced and underperforming innovation system. Key work: Jensen, Johnson, Lorenz & Lundvall (2007), "Forms of knowledge and modes of innovation," *Research Policy*.

Because tacit knowledge and interactive learning require trust and shared norms, *institutions* (formal rules and informal conventions) are constitutive of innovation, not external frictions. Social capital, labor-market organization, the structure of finance, and the education system determine whether interactive learning happens. This makes innovation policy a question of institution-building and coordination, not just price incentives.
