The Herfindahl-Hirschman Index (HHI) takes into account the relative size distribution of the companies that compete in a market. The larger the number of firms of relatively equal size the nearer to zero it approaches, and reaches its 10,000 maximum points when a market is controlled by just one firm. The Herfindahl index (also known as Herfindahl–Hirschman Index, HHI, or sometimes HHI-score) is a measure of the size of firms in relation to the industry and an indicator of the amount of competition among them. The term “HHI” means the Herfindahl–Hirschman Index, a commonly accepted measure of market concentration. The HHI is calculated by squaring the market share of each firm competing in the market and then summing the resulting numbers. The Herfindahl Index, also known as the Herfindahl-Hirschman Index (HHI), measures the market concentration of an industry's 50 largest firms in order to determine if the industry is competitive or nearing monopoly.
