As the predominant form of business and employment, small and medium-sized enterprises (SMEs) are key actors for building more inclusive and sustainable growth, increasing economic resilience and improving social cohesion. In fact, across the OECD, SMEs account for about 60% of employment and between 50% and 60% of value added and are the main drivers of productivity in many regions and cities. Yet, smaller firms face long-standing size-related barriers in dealing with stringent business conditions or accessing strategic resources. In practice, SMEs are a major target of public policy, and they are central to the policy agenda of many governments seeking responses to the challenges raised by globalisation and digitalisation.
SME structure is broadly comparable and stable across OECD countries overall, and SMEs generally concentrate in specific services with lower resource requirements. However, many dynamic changes are taking place, especially in areas highly exposed to the digital transformation. In fact, SMEs are a very heterogeneous population whose performance in terms of productivity, wages paid and international competitiveness, vary considerably across sectors, regions and firms.
