For most of human history, production and consumption have been tightly bundled together, as the prohibitive cost of moving goods resulted in a geographic clustering of production and people (Baldwin, 2006[1]). Baldwin and others argue that this situation was disrupted by two great production “unbundlings” that precipitated a significant expansion in global trade. The first of these unbundlings was highly aggregative, and had the effect of substantially increasing income disparities between countries – disparities that became persistent as firms in higher-productivity countries continued to innovate, scale and increase their productivity, and thus the price and quality competitiveness of their goods, via agglomeration.1 The second, brought about by a reduction in communication and co‑ordination costs, allowed firms in industrialised countries to take advantage of productivity-adjusted wage gaps in lower-income countries (Baldwin, 2006[1]) by unpacking their operations and beginning to “trade in tasks” (Grossman and Rossi-Hansberg, 2008[2]). This second unbundling affords firms in lower-income countries the opportunity to trade competitively2 on global markets, with trade in turn acting as a competitive pressure to incentivise the firm to boost its productivity over time.
The development of global value chains (GVCs) – a result of the second unbundling – enables countries to industrialise without first establishing an extensive industrial base. SMEs may have a particular role to play in this process. Their flexibility may enable them to adapt quickly, making them particularly well suited to fill supply niches (OECD, 2013[3]; OECD, 2008[4]). Linkages between SMEs and larger international firms can also be an important conduit for transferring know-how, technology and better quality inputs, and can allow SMEs to specialise while increasing their productive and innovative capacity (see also (López González, 2017[5]; OECD, 2018 forthcoming[6]). Internationalisation can also benefit SMEs in industrialised countries: SMEs often use internationalisation as a tool to grow and achieve economies of scale that would not be possible while operating in the domestic market alone (OECD, 2009[7]). Internationalisation may be particularly important for high-technology start-ups since it allows them to recover initial fixed costs more quickly, and because their business success often depends on being able to get to market and scale as rapidly as possible (Burgel et al., 2000[8]).
Despite these benefits, SMEs are generally less likely than larger firms to internationalise. Their limited size, resources, managerial structure and geographic location can result in informational, technical and administrative barriers that make it difficult to access finance, comply with quality standards, bridge connectivity and infrastructure constraints, innovate or find and develop suitable human capital (UNCTAD, 2010[9]; Harvie, Narjoko and Oum, 2013[10]). Policy interventions designed to increase SME presence in export markets and global value chains thus often focus on export financing facilities, training programmes and portals for international marketing, “business matchmaking” activities between SMEs and multinational corporations (MNCs), support to acquire internationally recognised product quality certification, support for attending international trade fairs and the creation of e-commerce platforms on which SMEs can list (Duval and Utoktham, 2014[11]; Yuhua and Bayhaqi, 2013[12]). These programmes are often part of a country’s overall economic development and/or export promotion strategy.
