Abstract Study of the Career Factors Determining the Research Results of Enterprise Researchers: Comparison of Two Career Stages: Junichi NISHIMURA, et al. Department of Psychology and Education, Tokyo Kasei University-The purpose of this study is to discuss the types of results of studies conducted by enterprise researchers and their differences according to generation as well as to divide the subjects into two groups, one group less than 40 years old (younger group) and the other 40 or more years old (elder group), comparing the career factors which determine the research results of both groups. For this purpose, we mailed a questionnaire to a total of 3,485 researchers from 83 companies selected by enterprise size from the Japanese pharmaceutical companies list. Among them, 1,067 people from 37 companies answered. We obtained the following results by analyzing the achievements in the last three years of 669 males who had been working for four or more years in the same company. (1) The factor analysis revealed that the research results could be divided into two types: the product development performance (PDP) and the research performance (RP). The two types of results showed a weak correlation with each other. (2) In PDP there was no difference according to generation. RP increased from the twenties to the forties, and thereafter it was stable. (3) The multiple regression analysis indicated that the promotional effect of "interaction with people from different industries " on PDP was developed in both the younger and elder groups. On the other hand, the encouragement effect of "expectation from the company" was only observed in the elder group. (4) The encouragement effect of "doctoral degrees", "number of academic society memberships" and "presence of company research reports" on RP was observed in both groups. On the other hand, whereas the promotional effect of "communication with other societies' members" was only observed in the younger group, that of "personal networks not possessed by others", "expertise not possessed by others" and "current occupational satisfaction" was only detected in the elder group.
