Malaysia has advanced a dynamic social innovation ecosystem by integrating inclusive development goals into its national and subnational strategies. Policymakers have embedded innovation-oriented objectives into long-term development visions, while medium-term Malaysia Plans have translated these visions into concrete programmes. Key policies, including the National Science, Technology and Innovation Policy, the National Social Innovation Policy, have mainstreamed community-based innovation, grassroots participation, and social enterprises (SEs) development. Various ministers and institutions such as Yayasan Inovasi Malaysia (YIM) have led major programmes that support grassroots innovators, build makerspaces, fund impact-driven startups, and foster academia-community collaboration. Local governments, for instances in Selangor and Sabah, have introduced grant schemes, strategic blueprints, and innovation hubs that empower marginalised groups and decentralise innovation governance. Despite this momentum, measurement gaps remain. To address this, a Social Innovation Scoreboard is proposed as a national performance framework guided by institutional theory, actor–network theory, and diffusion of innovation. The scoreboard offers input–output–outcome indicators to track ecosystem effectiveness and guide strategic alignment.
