What's the difference between industrial chain and supply chain?

The difference between industrial chain and supply chain lies in the following aspects:

1. research scope: the industrial chain takes industry as the node and takes the form of inter-industry association; The supply chain takes enterprises as nodes and takes the form of connection between enterprises. ?

2. Research focus: the industrial chain focuses on industrial links, enterprise layout and division of labor and cooperation, while the supply chain focuses on supply relations such as resource conversion and transmission among enterprises. ?

3. Research perspective: the supply chain is from a micro perspective, and the research perspective of the industrial chain is more macro.

4. Main objectives: The industrial chain aims at optimizing the technical and economic correlation between industries, seeking the maximization of the benefits of the whole industrial chain, improving industrial efficiency and comprehensive competitiveness of the industrial chain, and the supply chain aims at reducing the total production cost and improving supply efficiency. ?

5. Chain form: the industrial chain ultimately provides products and services to users, which inevitably involves production, supply and marketing. The transfer of resources is also a process of value appreciation, so the formation of the industrial chain is also a process of supply chain formation. Compared with industrial chain, supply chain is its material form.

6. Operation law: In the process of operation, the industrial chain is mainly influenced and restricted by external relations such as industry, internal relations of enterprises and national macro-policies, while the supply chain is mainly influenced and restricted by enterprise development strategy and the length and width of the industrial chain. ?
