SMEs play an important role in wealth creation and distribution through job creation, innovation, and participation in value chains. However, SMEs face problems including lack of access to financing, markets, skills and technology. To improve SME competitiveness and impact on economic development, policies need to address challenges at the macro, meso and micro levels in an integrated manner with SMEs as the central focus. This includes improving skills and technology diffusion, enhancing networking and clusters, and developing more comprehensive measures of national competitiveness that account for SME contributions.
