Lately it is said that the technical invation is retarded, but progress of the research and development (R & D) is expected so as to solve many difficult problems. So the purpose of this paper is to clarify the trends of the research activities in the construction and the peculiarity of it in comparison with the other industries. The main process of the analysis is (1) establishing the indexes to indicate the research activities, (2) grasping the transition of each index, (3) analyzing the difference in capital classes, (4) considering by the plural indexes, the complex indexes and the patern of the research activities. Resources which are invested in research activities are made up of the expenditure on R & D and researchers. About the expenditure the following are refered. (1) Percentage of accompanying R & D expenditure, (3) Intramural R & D expenditure as a percent to net sales, (4) Intramural R & D expenditure by type of cost, (5) Intramural R & D expenditure by type of activity, (6) Intramural R & D expenditure by product field. About the researchers the following are refered. (1) Number of regular researchers, (2) Number of persons engaged in R & D, (3) Number of regular researchers per 1000 persons employed by industry, (4) Regular researchers by field of science. About the plural indexes the following are considered. (1) Intramural R & D expenditure per regular researcher, (2) Concentration of R & D resources, (3) Intensity of R & D activities, (4) The patern of R & D activities.
