Developed countries tend to have predominantly secondary and tertiary sectors while being less engaged in the primary sector due to various reasons. The technological advancements in manufacturing and service sectors have led to increased efficiency, productivity, and profitability, enabling developed countries to focus on these sectors. Also, the higher demand for manufactured goods and services as compared to raw materials in developed countries makes investing in secondary and tertiary sectors more profitable. Developed countries often have limited natural resources, making it more cost-effective to import raw materials from other countries. Furthermore, the trend towards sustainable development and minimizing environmental impact has resulted in a shift towards cleaner industries in the secondary and tertiary sectors.
