Abstract

Este artículo demostró que la distribución de las ventas, la utilidad neta, los activos y el número de empleados de las quinientas empresas más grandes de México siguen la ley de Zipf. Luego de calcular los coeficientes de Zipf para el periodo de 2006 a 2017, estos fueron usados para crear una escala que mide tres distintos niveles de intensidad de competencia entre empresas, en seis sectores de la economía mexicana. Esta escala indica cuándo el sector está concentrado y cuándo se favorece la creación o destrucción de empresas. También se encontró el principio de Pareto en el comportamiento de las variables estudiadas. ****** This paper shows that the distribution of sales, net profit, assets and number of employees of the 500 largest companies in Mexico follow the Zipf Law. After calculating the Zipf coefficients for the period 2006-2017, they were used to create a scale that measures three different levels of intensity of competition among companies in six sectors of the Mexican economy. This scale indicates when the economic sector is concentrated and when the creation or destruction of companies is favoured. The Pareto principle was also found in the behaviour of the variables studied.
