The marketing channel width is the channel structure defined according to the number of channel middlemen at all levels. Channel width structure is influenced by product nature, market characteristics, user distribution and enterprise distribution strategy. The width structure of the channel is divided into the following three types.

Intensive distribution channel, also known as extensive distribution channel, refers to a channel type in which manufacturers choose as many channel middlemen as possible to distribute their products at the same channel level. Intensive distribution channels are more common in convenience products in the field of consumer goods, such as toothpaste, toothbrushes, drinks and so on.

Selective distribution channel refers to a channel type that selects a small number of channel middlemen to distribute goods at a certain channel level. In the IT industry chain, many products adopt selective distribution channels.

Exclusivechannel distribution channels refers to a channel type in which only one channel middleman is selected at a certain channel level. In the IT industry chain, this channel structure mostly appears at the level of general agent or general distribution. At the same time, many new products are launched by exclusive distribution. When the products were widely accepted by the market, many companies changed from exclusive distribution channels model to selective distribution channel model. For example, Toshiba's notebook product channel, Samsung's notebook product channel is like this.
