According to most definitions, small and medium-sized enterprises (SMEs) are companies with fewer than 250 employees and either an annual turnover not exceeding EUR 50 million or a total balance sheet not exceeding EUR 43 million.1 SMEs can be further broken down into micro, small and medium sized; although there is no common definition of these categories, the SME Intellectual Property Scoreboard categorises firms as micro if they have fewer than 10 employees and a turnover of less than EUR 2 million, and small if they have under 50 employees and a turnover of less than EUR 10 million (EUIPO, 2022[1]).
SMEs play a key role in most economies, and notably in OECD countries where they are the predominant form of business (around 99% of all firms in most OECD countries) and the major employers (around two-thirds of total employment). In addition, they contribute to more than half of value added in OECD countries. SMEs also actively participate in global value chains, where their indirect exporting activity (in value-added terms) is greater than their direct activities (in absolute terms). On average across OECD countries, SMEs accounted for 40% of gross exports and for 50% of the value added of gross exports. Figure 2.1 shows the gap between the direct and indirect export activity of SMEs in OECD countries. This reflects the role SMEs play as suppliers of inputs to larger direct exporters (OECD, 2021[6]).
