2. This theoretically-focused paper starts from the background of the industrial heritageand the theoretical foundation of protection study of the industrial heritage, and thenanalyzes the value composition of the industrial heritage to put forward that protectingthe value of technology is essential for protecting the industrial heritage. Theevaluation system and protection evaluation system of the industrial heritage can beestablished accordingly. On this basis and from the perspective of methodology, thispaper analyzes the model and method to protect the value of technology. It points outthat the method is to protect the physical objects and media which carry the value oftechnology instead of protecting the void value of technology itself, providing amethodological thinking for the protection of value of technology. To enhance thefeasibility of protection system of the industrial heritage, this paper specially analyzesthe decision-making system of industrial heritage protection and the relationships ofall stakeholders in this system, in order to meet the demands of all parties concernedin a possible way and to set up an effective decision-making system combiningtop-down and bottom-up formats with a clear objective. This paper connects everychapter organically and lays focuses on different case examples, and in the last section specifies the entire process of a case analysis to prove the feasibility of the protectionsystem of the industrial heritage.
