What is the industrial chain of IT industry?

1. What is the information industry chain? The information industry chain is a concept that includes four dimensions: value chain, enterprise chain, supply chain and spatial chain. These four dimensions form the industrial chain in the balanced process of mutual docking. This "docking mechanism" is the internal model of industrial chain formation. As an objective law, it regulates the formation of industrial chain like an "invisible hand".

industrial chain is a concept in industrial economics, and it is a form of chain-like relationship objectively formed among various industrial departments based on certain technical and economic relations and according to specific logical relations and spatial-temporal layout relations. The industrial chain is mainly based on the objective regional differences in different regions, focusing on giving full play to regional comparative advantages, coordinating the contradiction between specialized division of labor and multi-dimensional demand between regions with the help of regional markets, and taking industrial cooperation as the carrier of regional cooperation to realize the form and content.

The essence of industrial chain is to describe the structure of an enterprise group with certain internal relations. It is a relatively macro concept with two-dimensional attributes: structural attribute and value attribute. There are a large number of upstream and downstream relationships and mutual value exchanges in the industrial chain. The upstream link delivers products or services to the downstream link, and the downstream link feeds back information to the upstream link.
