8. Auto Parts And Accessories Manufacturing
Revenue: $2,500 billion
In the last couple of years, the global auto parts and accessories manufacture and repair industry has greatly benefited from improving economic conditions in the world. With the rise of per capita income globally, individuals that fall under the “middle class” have purchased vehicles and also some of the needed parts.
As the burgeoning middle class continues to demand more vehicles, car manufacturers have also demanded more parts from industry operators. As more people continue to demand these vehicles, the revenue of this industry and other related ones continue to soar.
