The Herfindahl-Hirschman Index (HHI) is a common measure of market concentration and is used to determine market competitiveness, often pre- and post-merger and acquisition (M&A)transactions. The index measures the size of companies relative to the size of the industry they are in and the amoun...
Herfindahl-Hirschman Index (HHI) Introduction Calculation To calculate the HHI, follow these steps: 1. Obtain the market shares of all firms within the industry. 2. Square each firm's market share. 3. Sum the squared market shares of all firms. The formula to calculate the HHI is as follo...
How is the Herfindahl-Hirschman Index (HHI) Calculated? To calculate the Herfindahl-Hirschman Index, we take the percentage market share of each firm in an industry, square that number, and then add all the squares together. The formula to calculate Herfindahl-Hirschman Index is as follows: Whe...
This could be achieved by including in the draft Guidelines a formula modeled on the Herfendahl-Hirschman Index(HHI)tomeasure market concentration. legco.gov.hk legco.gov.hk 為達致此目的,指 引擬稿可納入以Herfendahl-Hirschman指數( 下稱“HH指數”) 為藍本的方程式,量度市場集中程度。
30 percent and 20 percent, the HHI would be (50² + 30² + 20²), or 3,800. Using this index, HHIs can theoretically range from zero (a market with infinitely many competitors, each having infinitesimal shares) to 10,000 (a market with a single monopolist, having a 100 ...

Hirschman, it is based on the following formula: HHI = s12 + s22 + ⋯ + sn2 where n is the number of firms in the market and sn denotes the market share of the nth firm. Higher values of the index indicate higher market concentration and monopoly power as well as decreased ...
Background—competitive conditions are often distorted in the construction sector, therefore this affects the market position of all participants. This paper seeks to find the tools for properly assessment of participants by Herfindahl-Hirschmann index (
As the hardness η is found in the denominator of the equation defining the electrophilicity ω index (see Equation (1)) [60], a decrease of the hardness η provokes a noticeable increase of the electrophilicity ω index. On the other hand, the hardness η is approaches the HOMO-LUMO gap...
