价值链概念是20世纪80年代中期由美国学者迈克尔·波特在《竞争优势》一书中提出的。他认为企业的每项生产经营活动都是创造价值的经营活动,价值链就是一个企业的众多与战略相关的活动组成的链条,是企业创造价值的动态过程,由基本活动和辅助活动组成。 The concept of the value chain was put forward by American scholar Michael Porter in his book Competitive Advantages in the mid-1980s. In his opinion, every production and management activity of an enterprise is a business activity that creates value. A value chain is a chain of many strategic and business-related activities of an enterprise. It is a dynamic process of creating value for an enterprise and consists of basic activities and auxiliary activities.
