Final answer:
A country moving from primary to secondary economic activities is classified as a developing or emerging industrial economy. This transition indicates a focus on manufacturing and indicates economic growth and diversification.
Step-by-step explanation:
A country that has recently transitioned from primary economic activities to secondary economic activities would be classified as a developing country or an emerging industrial economy. This shift often indicates an economic transition towards more industrial and manufacturing processes, which typically follow extractive industries such as mining or agriculture. Countries in this phase experience significant changes, including rapid growth and the process of privatization, where government-owned businesses are sold or transferred to individuals, thereby fostering a more diversified economy.
In developing countries, the majority of the population is initially employed in the primary sector, which involves the extraction and production of raw materials. As the economy grows, employment in the secondary sector becomes predominant, with manufacturing and industrial activities transforming those raw materials into finished goods. This transition can also reflect an economic strategy focused on achieving a sustainable national income through value-added principles. Over time, successful development of the secondary sector can lead to further economic evolution towards the tertiary service industries.
