The present study aimed to examine the factors that influenced governance quality in Tanzania and analyze their potential implications for policy formulation and socio-economic development. This study employed a time series approach to investigate the associations between multiple variables, such as gross fixed capital formation, foreign direct investment, trade openness, GDP per capita growth, and agricultural exports, and governance outcomes. The results indicated that GDP per capita and trade openness positively influenced governance quality, while gross fixed capital formation had a negative influence due to its concentration in traditional sectors, which limited new advancements that could enhance governance quality. This study offered significant insights for policymakers and stakeholders in Tanzania. It recommended the implementation of comprehensive strategies that facilitated the improvement of trade openness and diversity of capital accumulation towards higher productive sectors to promote economic development and efficient governance practices. Through the improvement of governance quality, Tanzania had the potential to promote sustainable development, enhance the delivery of services, and augment the overall well-being of its populace.
