Resumen
Ecuador importa productos en acero plano debido a que no posee la industria siderúrgica para hacer su propia producción, esto lo hace dependiente de la producción del mercado internacional donde el principal proveedor se ha vuelto la República Popular China teniendo una posesión del 39% del mercado internacional. La importación de acero dinamiza a varios sectores dentro de la economía ecuatoriana como el sector metalmecánico, el cual aporta en 14% del PIB nacional. Sin embargo, existen cuatro empresas que concentran el mercado importador de acero plano, configurando una figura oligopólica que precisa de cuotas para mantenerse como tal. El presente trabajo de investigación se justifica porque no existen estudios que involucre al sector importador de planchas de acero, sobre todo que involucre la concentración donde intervienen algunas empresas. El resultado de esta investigación es que el mercado es concentrado medido desde los índices de concentración, Herfindahl y de Volatilidad o inestabilidad en el mercado. La concentración de mercado tiende a disminuir con la imposición de elevadas tasas arancelarias que elevan los costos y por consiguiente el precio.
Ecuador imports products in flat steel because it does not have the steel industry to make its own production, this makes it dependent on the production of the international market where the main supplier has become the People's Republic of China having a 39% possession of the international market. The import of steel energizes several sectors within the Ecuadorian economy such as the metal-mechanic sector, which contributes 14% of the national GDP. However, there are four companies that concentrate the import market for flat steel, forming an oligopolistic figure that requires quotas to remain as such. This research work is justified because there are no studies involving the steel plate importer sector, especially involving the concentration where some companies intervene. The result of this research is that the market is concentrated measured from the concentration, Herfindahl and Volatility indices or instability in the market. Market concentration tends to decrease with the imposition of high tariff rates that raise costs and consequently the price.
