This paper is the first to employ multiple outputs, patents and net sales, in our data envelopment analysis (DEA) to examine whether operational efficiency improves after enterprise resource planning (ERP) installations. The ANOVA analysis results show that granted patent number significantly increases after ERP installations. ERP implementation indeed stimulates integrated circuit firms to concentrate on innovation activities. Also, the DEA results show that firm efficiency significantly increases after the third year subsequent to ERP implementations. The Tobit regression results further prove that the curtailing of receivable turnover days and inventory turnover days are attributed to efficiency elevation through ERP installations.

Previous studies mostly focus on bank performance, but few studies have effectively investigated how efficiency is reduced as banks expand credit card or cash card issuances. This study seeks to investigate how bank's relaxations of card issuance and credit revolvers reduce bank efficiency during card insolvency crisis in the Taiwanese banking industry. The results show that the credit card insolvency crisis reduces bank efficiency. Particularly, banks with low card issuance levels perform better than those with high card issuance levels. This suggests that if banks approve card applications while neglecting an applicant's capability to repay the card debt, they will suffer losses. Furthermore, the regression used in this study indicates that bank efficiency is negatively related to the issuances of credit cards, issuances of cash cards, and the revolving amount of credit cards. These findings imply that the relaxations relating to the card issuance or loosened approvals of credit revolvers reduced bank profits resulting from unpaid debts.
