—The impact of employment systems on
productivity performance is a crucial management issue not
limited to labor-intensive enterprises. Japanese companies do
not recognize the importance of employment information. In
order for executives to understand its importance, this research
verifies the effectiveness of employment information on
productivity performance in Japanese companies. In addition,
influential information categories and indicators with respect to
productivity performance are identified. DEA and DEA
Malmquist Indices are applied so as to define productivity
performance. As a result, the companies, which actively engage
in disclosing employment information, tend to be productive.
Furthermore, the model including quantitative indicators
calculated from employment information is more explanatory
than the model including solely financial indicators. In
particular, turnover rate, average length of service and average
annual salary are the most influential indicators. Contrary to
the philosophy of long-term employment, higher liquidity is
preferred in Japanese companies.
