which of the following is a measure of the degree of industry concentration

The degree of concentration of an industry can be measured using a few different measures. These include the concentration ratio, the Herfindahl-Hirschman Index, and the Concentration ratio. Let’s look at each one in detail. You can then use the data to find out whether a certain industry has too much or too little concentration.

Herfindahl-Hirschman Index

The Herfindahl-Hirschmann Index measures industry concentration by comparing the number of firms in an industry with the number of competitors. The index ranges from 1/N to one, and the percents are expressed as whole numbers. An industry with a low index indicates high competition, while a high index means little competition.

The Herfindahl-Hirschmann Index is a common measure of market concentration, and is often used to determine market competitiveness. It measures the concentration of an industry in terms of its number of competitors, and it is often used to gauge whether a company is becoming too monopolistic or too diversified.

The Herfindahl-Hirschmann Index is not a perfect tool to measure industry concentration, however. Its definition of market share is different for different firms, and therefore, the numbers will be different. In addition, the Herfindahl-Hirschmen Index does not take into account the possibility of new companies entering a market. A high concentration means that fewer companies have a chance of competing with the existing firms.

Whether an industry is concentrated or not is determined by a number of factors. One of the most important factors in determining industry concentration is the number of companies within an industry. The Herfindahl-Hirschman Index is a commonly used metric in market analysis and is commonly used by regulators to evaluate merger and acquisition deals. This metric also helps analyze companies’ financial performance.

The Herfindahl-Hirschmann Index can range from zero to one thousand. If there are few competitors in an industry, the Herfindahl-Hirschman Index is closer to one, while if there are many firms competing, the index is closer to zero. The Herfindahl-Hirschlman Index is a useful tool to monitor industry concentration.

The higher the HHI value, the more concentrated an industry is. In a competitive industry, HHI values between one and ten are regarded as healthy. A value close to ten indicates that a company has a monopoly, while a weight of zero indicates healthy competition.

The HHI has an important impact on fund performance. Funds with a high industry concentration have lower expense ratios. This results in better performance.

Concentration ratio

The Concentration Ratio (CR) is a statistic that measures the degree of industry concentration. The CR is an important indicator for assessing the economic health of an industry. The degree of concentration varies across industries. For example, in the automotive industry, the four largest firms have a CR of 84%. However, when adding imports, the CR is only 70%. In contrast, in the breakfast cereal industry, the CR is 85%.

To better understand what CR means, let’s consider an example. In an industry with a CR of 80%, the four biggest companies control approximately 80% of the market. This indicates oligopoly. In contrast, a CR of 0% to 50% indicates perfect competitiveness, and a CR of 90% implies that there is no competition.

The Herfindahl index is another measure of industry concentration. It measures the size of firms by calculating the square root of their market shares. For example, if there are five firms in a market, the Herfindahl index would be 3000. In a market with a monopoly, this number could rise as high as 10,000. Using the Herfindahl-Hirschman Index as an indicator of concentration is a useful tool for assessing the competitive environment of an industry.

While the Concentration Ratio is a simple way to compare the degree of industry concentration, it is not a highly accurate indicator of the competitive state of an industry. The CR measures the number of large firms in an industry, which in turn reflects the concentration of power in the market. A high concentration ratio indicates a monopoly or oligopoly, while a low CR shows competitive conditions in an industry.

The CR is used to compare the number of companies in an industry against the total market share. If market share details are available for an industry, this metric can be calculated easily. It can also be calculated using data from each firm’s sales. The CR can be a good indicator of industry concentration if the largest companies in the industry have the same market share.


The CR4 index represents the level of competition in the industry. A low CR4 index value indicates a more competitive market, while a high CR4 index value indicates a monopoly or oligopoly situation. Companies with a CR4 index value over 40 have very high levels of concentration. This index is updated periodically by the U.S. Census Bureau.

Concentration indices are often used to analyze the degree of competition in an industry, and to examine concerns about the creation of dominant positions. A few of these concentration indices are the CR4 index and the Herfindahl-Hirschman Index (HHI).

The concentration ratio is calculated as the sum of the market share percentages of the largest firms in an industry. The ratio ranges from 0% to 100%. A concentration ratio near 100% indicates a high concentration level. A CRn of n/N indicates perfect competition, while a concentration ratio of 100% suggests a monopoly.

When the ratio of three firms exceeds 80%, it can signal monopoly power and collusion. In such a case, government may need to regulate the industries. Railways, electricity, and gas are examples of industries where the government has the authority to regulate competition. While the concentration ratio itself does not necessarily reflect the level of competition in an industry, the threat of competition may help keep prices low.

The percentage of new product innovations in an industry can also be a measure of concentration. Firms that are able to develop new products are often better-positioned to dominate the market. However, not all new products that are introduced will be commercially successful. For example, companies developing genetically modified crop varieties usually get patent protection first and go through extensive field trials before receiving regulatory approval to sell seed.

This measure also gives an idea of the proportion of workers employed in a specific occupation in a given industry. If an industry has a high concentration of industry quotient, it is likely that most of its workers are concentrated in a single industry. This can make it difficult to compare different occupations or determine which industries use certain occupations intensively.


The CR5 index measures industry concentration by comparing the market shares of the five largest companies in an industry. The higher the concentration, the slower industrial growth will be. Industry concentration can be reduced by reducing the market share of the largest firms. The CR5 index can be calculated using data from the World Bank Global Financial Database.

Concentration ratios are used to analyze the degree of concentration. The concentration ratio is defined as the percentage of firms that account for more than half of the market. A higher concentration ratio indicates a more monopolistic industry. A low concentration ratio means that there are few large firms. A high concentration ratio means the top five companies control most of the market.

Concentration ratios can be calculated in a number of ways. One metric is the “n-firm” concentration ratio, which measures the percentage of total sales of the largest firms in a particular industry. Another method is the “herfindahl-hirschman index.” The U.S. Census Bureau collects concentration ratio data every five years. It uses this index to compare the concentration levels of various industries. The highest concentration ratios indicate oligopoly, while the lowest concentration ratios indicate healthy competition.

While the CR5 index provides a general idea of industry concentration, it does not provide details on specific industries where a particular occupation is frequently employed. Another way to measure industry concentration is with location quotients, which analyzes data by geographic region. The standard location quotient is based on the ratio of employment in an area versus the total national workforce. An industry quotient, on the other hand, measures the ratio of a specific industry to all industries in an area.

Industry concentration is an important component in determining an organization’s success and longevity. Without an adequate understanding of the competition in an industry, it can be difficult to ensure a firm’s longevity. A high CR5 concentration ratio has positive implications for an organization’s profitability.

The CR5 index represents the market share of the five largest companies in an industry. Its values range from 0.661 for Thailand to 0.781 for the Philippines. Nevertheless, CR is not the same as HHI, so a comparison should be made using HHI data. The highest concentration index is in Singapore, while the lowest is in Hong Kong.
