The purpose of this study is to evaluate researchitivity of R&D organization by using 'Data Envelopment Analysis(DEA)J , which is a technique used to measure researchitivity of 'Decision Making Unit(DMU)'. For this purpose, a chain of procedure to design DEA indicators for evaluating researchitivity in R&D organization is as follows; First, we have revised R&D input factors by 'creativity indicator'. Labor and cost indicators are used in general area, But there is a necessity for reflecting 'creativity' of R&D organization on these indicators in R&D area. Second, R&D output factors are classified into two types of data in this study; intemationa'domestic and registration/application of patents. And then we have calculated indices of the 'technology newness' and the 'technology sharpness'. we give a name these 'technical quality' 'technology indicator'. Finally, we have examined researchitivity by using DEA in R&D input and output indicators revised as 'creativity' & 'technical quality'. And then, we have analyzed researchitivity in terms of 'overall', 'technique/ scale' and 'trend' by DEA. By using the results of these analyses, there are accurate measurement and evaluation on researchtivity. Moreover, it is expected that the efficient strategies will be worked out improvement of creativity.
