What does industrial chain mean?

Industrial chain is a concept that includes four dimensions: value chain, enterprise chain, supply chain and spatial chain. These four dimensions form an industrial chain in the process of mutual docking and balance. This "docking mechanism" is the internal mode 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, which is a chain-like relationship form objectively formed among various industrial departments based on certain technical and economic relations and according to specific logical relations and spatial and temporal layout relations. 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 realizing regional cooperation in form and content with industrial cooperation as the carrier.

The essence of industrial chain is to describe an enterprise group structure with some internal relations. It is a relatively macroscopic concept with two-dimensional attributes: structural attribute and value attribute. There are a lot of upstream and downstream relationships and mutual value exchange 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.
