Abstract: This research has built a database of key and core technologies in bio-medicine field through collection of information on national scientific development plans, key research and development project and corporate technological demand at first, and then an index system for thorough selection of key and core technologies with an escalation label from being important, monopoly, advanced, difficult to being valuable is build. With the system, based on the Delphi method and analytic hierarchy process model, the exclusively “neck-jamming” technologies in the bio-medicine field are carefully and thoroughly selected. The selected “neck-jamming” technologies are verified by patent analysis method. The results demonstrate that the three selected “neck-jamming” technologies are all global research hotspots, but foreign patents outnumber domestic patents. The number of domestic patents is lower the that of top countries. It is insdicated that China relatively lags behind on the selected three technologies and these technologies are located in important place of the value chain and industrial chain. Finally, according to the analysis of the selection results, the relevant policy suggestions aiming to fill in the gaps in the “neck-jamming” technologies in the bio-medicine field are put forward.

Key words: “Neck-jamming” Technologies, Delphi Method, Analytic Hierarchy Process Model, Biological Medicine
