学歴と企業規模から見た情報技術者の労働市場―初職からの離職行動に着目して―

抄録

The environment surrounding ICT engineers' labor market has changed in the latter half of 1990s. The sophistication of ICT is getting more promoted and the number of highly educated ICT engineers is increasing. In previous studies, they point out that firm size and schooling directly affect the extent of internalization of ICT engineers, and indirectly have effects on their wage and occupational attitudes. However, because these arguments are based on survey data collected before around 2000, they do not catch up with the current trend of ICT engineers' labor market. In this study, we analyze ICT engineers' turnover rate from their first jobs after graduation, and examine whether the hypotheses that firm size and schooling determine ICT engineers' career development are still valid in the 2000s.From the results of analysis, we found following facts; (1) The hypothesis that firm size determines the extent of internalization of ICT engineers is still valid in the 2000s. (2) The hypothesis that schooling determines the extent of internalization of ICT engineers does not seem to be valid on those who became ICT engineers after 2000. (3) Schooling is an important determinant of sizes of firms which ICT engineers join first after graduation. After they join firms, however, there is no significant difference in the extent of internalization between education levels except those who finished graduate schools. (4) In every education level, the smaller the size of the firm where ICT engineers work is, the higher the turnover rate is. (5) Only in college graduates, those who became ICT engineers after 2000 tend to leave their first jobs more than those before 1999.
