"Research and development period"is often referred in discussions about R&D management. However, their meanings and lengths vary, such as with who executes R&D activities, academy or industry, and with stages from which R&D activities start. Therefore, consistent arguments and understandings are not developed enough hitherto. In this report, 48 recent R&D success cases for 21 Japanese large enterprises are divided into 4 industry segments, automobile, heavy machinery, chemistry and electric & electronics. Then average research and development periods are derived for each industry segment. In consequence, it is clarified that research and development periods vary with the industry segment, depending on their product cycles, have strong correlations with R&D innovation patterns, and faithfully reflect new business creation strategies in each industry segment.
