 note = {This study examines changes in productivity for seven countries including Japan and performs their decomposition into four factors from 1999 to 2019. For this purpose, this study measures total factor productivity using a combination of multiple inputs and outputs. We include a number of articles as an output, and a total amount of research and development costs as an input for production in order to incorporate innovation factors into the productivity measurement. Concretely, we measure the Hicks- Moorsteen-Bjurek (HMB) productivity index with a consideration of inefficiency by applying data envelopment analysis models. Further, the HMB productivity index is decomposed into four factors; technical change, efficiency change, scale change, and input and output mix effects components. The results indicate that Japan’s HMB productivity index for the period 1999-2019 is the third highest after Korea and Germany, which is mainly attributed to the higher technical change component that represents technological progress or frontier shift over the period.},
