Africa is the second continent in the world after Asia. It is rich in natural resources, but its industrialization level has always been in a backward position. The backward industrial situation in Africa has profound historical reasons. Since the early 1960s, African countries that have gained independence one after another have made great efforts to develop their industries. However, due to the lack of necessary funds and technology at that time, they have never been able to establish their own complete industrial system. In addition, the former suzerain continued to implement a single economic policy towards Africa, taking Africa as its raw material producing area and commodity market. The above factors make Africa's economic structure single, and most of its export products are resource-based products with low added value. The single economic structure also directly leads to the slow development of African industry. In addition, many unfavorable factors such as continuous wars, heavy foreign debts, poor management, corruption and brain drain have further restricted the industrial development of African countries. Sub-Saharan Africa accounts for only 0.7% of the world's industrial output value, and only 0.5% if South Africa is not included.
