英文文章：Like value chain and supply chain, “industrial chain” becomes the focus of attention. The implication of “industrial chain” has gained a large range of extension. It not only expresses the industrial “chain” structure and relationship of “back and forward”in order or “up and down” in direction, but also it represents a cluster of large scale of firms in an area or colony. It is a network, or a community. Consequently, we conclude that “industrial chain” is a synthesis of industrial chain, industrial cluster, or industrial network.In this article, firstly we will distinguish industry chain from industry. An industry is the collection of firms that have the same attribute, so an industry can be defined by firm collection of certain attribute. We indicate that industrial chain is a kind of vertical and orderly industrial link. It is defined according to a series of specific product or service created. Secondly we analyze the vertical orderly defiinition process from the aspects of social division of labor and requirement division, self-organization system, and value analysis.Non-symmetry and depending on system or community of large scale of industrial units lead to entire industry to “orderly” structure. On the other hand, the draught of diversity and complexity of requirement simultaneously lead to entire industry to be more “orderly”. Along with processes of self-organization, industrial will appi'oach the state of more orderly and steady, and constantly make industrial chain upgrade. Each firm or unit, who will gain the value, has to establish channels of value, which we called “industrial value chain”. Lastly,we discuss the consequence of vertical and orderly definition, which is exhibited by a certain relationship body. The typical forms of industrial chain include industrial cluster, strategy alliance and vertical integration etc.

英语文章：
In commerce, supply chain management (SCM), the management of the flow of goods and services,[2] involves the movement and storage of raw materials, of work-in-process inventory, and of finished goods from point of origin to point of consumption. Interconnected or interlinked networks, channels and node businesses combine in the provision of products and services required by end customers in a supply chain.[3] Supply-chain management has been defined [4] as the "design, planning, execution, control, and monitoring of supply chain activities with the objective of creating net value, building a competitive infrastructure, leveraging worldwide logistics, synchronizing supply with demand and measuring performance globally."[5] SCM practice draws heavily from the areas of industrial engineering, systems engineering, operations management, logistics, procurement, information technology, and marketing [6] and strives for an integrated approach.[citation needed] Marketing channels play an important role in supply chain management [6] Current research in supply chain management is concerned with topics related to sustainability and risk management, among others, whereas the “people dimension” of SCM, ethical issues, internal integration, transparency/visibility, and human capital/talent management are topics that have, so far, been underrepresented on the research agenda
