The paper provides a number of contributions to the innovation literature: first, it adds to the revived debate on demand-pull perspectives in innovation studies by examining demand-related (lack of) incentives to invest in innovation. Second, it complements the literature on barriers to innovation by focusing on demand-related obstacles rather than the more frequently explored financial barriers. Third, it analyses whether experiencing demand barriers is a sector-specific feature. Firms active in high-or low-tech manufacturing or in knowledge-intensive or low-tech services might be more or less dependent on demand conditions when deciding to perform R&D. We find that uncertain demand and lack of demand are perceived as two quite distinct barriers. While the perception of a lack of demand has a marked negative impact not only on the amount of investment in R&D but also the likelihood of firms to engage in R&D activities, demand uncertainty seems, on the contrary, to represent an incentive to spend more in R&D, although only in low-tech sectors. We interpret this evidence in terms of the specific phase of the innovation cycle in which decisions to invest in R&D are taken. Sectoral affiliation seems to be playing a role only for demand uncertainty, supporting the conjecture that positive expectations on the presence of adequate market demand are a necessary condition to invest in R&D.R&D strategyBarriers to innovationDemand uncertaintyLack of demandInnovative inputsPanel datatext::journal::journal article::research article
