This chapter explores a comparative analysis of government support for research and development (R&D) and its impact on gross domestic product (GDP) growth across diverse countries, including Peru, Nepal, Pakistan, and Nigeria. By examining R&D policies, practices, and outcomes in these nations, the study aims to elucidate the complex relationship between government initiatives and economic metrics. Key findings highlight the importance of tailored R&D strategies, tax incentives, and funding mechanisms in driving innovation, job creation, and industrial competitiveness. Insights from this analysis offer valuable guidance for policymakers, stakeholders, and researchers seeking to foster sustainable economic development through effective R&D interventions. The case studies presented underscore the critical role of government support in shaping innovation ecosystems and advancing inclusive, innovation-driven economies.
