El método se basa en la cercanía de los bienes producidos dentro de un país, la cual se establece por la estructura de la producción. Los productos que están simultáneamente presentes en la estructura productiva de un país son cercanos. Los productos se especifican según la Clasificación Uniforme del Comercio Internacional (CUCI) y, más recientemente, según el Sistema Armonizado. Argumentamos que, en el contexto de la creciente fragmentación internacional de la producción, la complejidad de las economías debe establecerse según su especialización por fases en los procesos productivos. Se estima la calidad de las exportaciones mexicanas de acuerdo con indicadores de composición de las exportaciones, origen del valor de las exportaciones, eslabonamientos hacia atrás de los sectores exportadores, tipos de bienes exportados y su uso por los importadores, propiedad del capital de las empresas exportadoras, investigación y desarrollo en los sectores exportadores y precios unitarios.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Hausmann, Rodrik, and Klinger determine the quality of exports according to the level of complexity of economies. The method is based on the closeness of goods produced within a country, which is established by the production structure. Products simultaneously present in a country&#8217;s production structure are close. Products are specified according to the Standard International Trade Classification (SITC) and, more recently, to the Harmonized System. We argue that, in the context of increasing international production fragmentation, the complexity of economies should be established in line with their specialization by stages in the production processes. The quality of Mexican exports is estimated based on indicators of export composition, origin of the value of exports, backward linkages of exporting sectors, types of exported goods and their use by importers, capital ownership of exporting firms, research, and development in exporting sectors, as well as unit prices.]]></p></abstract>
