An element of understanding global competitive dynamics is to assess the industry concentration of different industries. To accomplish this, the percentage of overall industry sales coming from the largest manufacturing companies in an industry can be used as a proxy. Based on this approach, categorize the following four industries from most to least concentrated by using the sales of the top four companies in the report you locate on globalEDGE: aerospace and defense, beverages, chemicals, and food. Which countries are represented across these four industries? What insights concerning competitive dynamics in each industry can your evaluation provide?
