What Are The Four Supply Factors Of Economic Growth

Economic growth, the sustained increase in a country's production of goods and services, is a fundamental driver of improved living standards and overall societal well-being. Because of that, while demand-side factors play a role in stimulating short-term fluctuations in economic activity, the long-run growth potential of an economy hinges on its supply-side capabilities. Specifically, the four supply factors of economic growth – natural resources, human resources, capital formation, and technological advancements – determine the quantity and quality of goods and services an economy can produce. These factors are interconnected and influence each other, shaping the economic trajectory of nations.
