Empirical Research on Technology Share Based on Hybrid Approach for Morphology Analysis and Conjoint Analysis of Patent Information

This paper presents an empirical study on the technology share index with a case of optical lithography technology by hybrid approach for morphology analysis and conjoint analysis of patent information. First of all, key words in patents of optical lithography technology are found out by text mining method to build matrix; then, technological configurations are identified according to the morphology matrix; subsequently, the part-worth of every level and utility of every patent are calculated by combining conjoint analysis and patent citation count; finally, technological innovative capability of corporations can be evaluated by technology share. The results reveal technology share index can be useful in the dynamic analysis of technology change in fields, helping corporation leaders make strategic plans.
