| dbo:abstract | Die Unternehmenskonzentration ist in der Wirtschaft die Tendenz zur Monopolisierung von Unternehmen. (de) Este concepto está ligado al de concentración industrial, que concierne a la repartición de la producción en una industria. Las medidas corrientes de esta noción son el índice de Herfindahl-Hirschmann (IHH, HHI, índice de Herfindahl, o simplemente índice H), así como la llamada (en inglés, concentration ratio o CR). (es) In economics, market concentration is a function of the number of firms and their respective shares of the total production (alternatively, total capacity or total reserves) in a market. In any industry, a handful of firms that hold a significant portion of the market share and likely engage in the practice of consolidation will indicate higher market concentration within that industry. The market concentration ratio measures the concentration of the top firms in the market, this can be through various metrics such as sales, employment numbers, active users or other relevant indicators. In theory and in practice, market concentration is closely associated with market competitiveness, and therefore is important to various antitrust agencies when considering proposed mergers and other regulatory issues. Market concentration is important in determining firm market power in setting prices and quantities. Market concentration is affected through various forces, including barriers to entry and existing competition. Market concentration ratios also allows users to more accurately determine the type of market structure they are observing, from a perfect competitive, to a monopolistic, monopoly or oligopolistic market structure. Market concentration is related to industrial concentration, which concerns the distribution of production within an industry, as opposed to a market. In industrial organization, market concentration may be used as a measure of competition, theorized to be positively related to the rate of profit in the industry, for example in the work of Joe S. Bain. An alternative economic interpretation is that market concentration is a criterion that can be used to rank order various distributions of firms' shares of the total production (alternatively, total capacity or total reserves) in a market. (en) Une concentration d'un marché consiste en un regroupement d'entreprises entrainant une modification durable de la structure du marché, une perte d'indépendance des différentes entreprises regroupées et un renforcement du pouvoir économique de l'ensemble. Elle s'apprécie principalement en fonction du nombre d'opérateurs présents, de leur dynamisme effectif respectif et de leurs parts individuelles détenues sur le total du marché. Cette caractéristique, souvent appelée simplement concentration, peut théoriquement être appréciée tant du côté de l'offre que de la demande. Le terme s'applique également à l'étude de la répartition de la production au sein de sous-secteurs industriels (on parle alors d'étude de la concentration industrielle) par exemple pour le secteur de l'agro-alimentaire, de l'armement, des médias, de la pharmacie, de la chimie, etc. La notion est à distinguer de la situation d'« intégration d'un marché », qui suppose des acteurs multiples, mais un lieu central de confrontation de l'offre et de la demande. (fr) Em economia, concentração de mercado, ou concentração no ramo de atividade, é uma função do número das empresas e das suas respectivas quotas de mercado no total das vendas (ou, em alternativa, dos activos ou dos empregados totais) num mercado ou indústria. Em organização industrial, a concentração de mercado pode ser usada como uma medida da concorrência, que segundo alguns autores, como Joe S. Bain, se relaciona positivamente com a taxa de lucro numa indústria, ou ramo de actividade. (pt) Ры́ночная концентра́ция (англ. market concentration) — относительная величина и количество предприятий, действующих на рынке. Это явление зачастую называется просто концентрацией. Рыночная концентрация связана с понятием , касающимся сосредоточения производства родственных видов продукции на нескольких крупных предприятиях региона. Показатели этой величины: индекс Херфиндаля-Хиршмана (HHI, ХХИ) и (англ. concentration ratio, CR). (ru) |
