Abstract
A statistical survey on the production of scientific papers by seven countries during a period of 1976-1993 was conducted. The survey covered 27 scientific fields in physics, chemistry, engineering and medicine. Outline of survey result was already published. In this paper, the research trend in six developed countries during 1976-1993 was analyzed based on this statistics. Two indices, number of papers published in 1993 and difference between number of papers published during in 1976-1984 and in 1985-1993 (both indices were represented as relative number to 1976) were found to be useful to describe characteristics of the trend in paper production of each country in each field, by multidimensional scaling technique. It was revealed that Japan continued to increase its share in most fields, but the speed of increase was decreased in many fields in latter half of period. It was also shown that the trends of Japan in chemical engineering (CA) and some other fields were different from that in many other fields.
