Regarding the methodology, we divided the products into the following ranges: a null Intra-Industry Trade Index ITI, which means that trade is only "one-way;" b products with a positive ITI, less than 33%, for which the trade overlap is extremely low;c products with an ITI greater than or equal to 33%, but less than 66%, which we call a "considerable" degree of intra-industry trade; and d products with an ITI between 66% and 100%, which have very high intra-industry trade flows.
Sobre los aspectos metodológicos, segmentamos a los productos en los siguientes rangos: a Índice de Comercio Intraindustrial ici nulo, que significa que el comercio se da en "un solo sentido"; b productos con un ici positivo, y menor a un 33%, sobre los cuales el solapamiento comercial resulta sumamente reducido; c productos con un ici mayor o igual a un 33%, pero menores a un 66%, a lo que denominamos con un grado "considerable" de comercio intra-industrial y, d productos con un ici comprendido entre un 66% a un 100%, para los cuales los flujos de comercio intra-industrial son elevados.
