How does international trade impact economic growth within a trading nation?

International trade stimulates economic growth by allowing nations to specialize in the production of goods and services they can produce most efficiently, leading to increased productivity and innovation. It expands market access, enabling countries to sell their products to a larger customer base, which can boost revenues and create jobs. Furthermore, trade encourages competition, driving down prices and improving quality for consumers. Overall, these factors contribute to a more dynamic economy and higher GDP growth rates.
