This study attempts to make an empirical contribution to the understanding of corporate performance in the telecommunications industry. Data envelopment analysis (DEA) is performed to assess corporate performance for the telecommunications sector in Taiwan and the relationships between corporate performance and merger and acquisition (M&A) transactions. The empirical results reveal that M&A strategy does not seem to enhance corporate performance in the telecommunications industry, whilst an internal growth strategy does improve corporate performance.

This study applies 3-stage data envelopment analysis (DEA) model on a sample of 29 foreign commercial banks in Taiwan in order to measure their overall operational efficiencies. Exploring adjustments on environmental and statistical noise effects incorporated in the pure performance evaluation for input slacks to achieve true managerial efficiency. Through our research, using a three-stage DEA approach, efficiency scores can function as a more specific and precise set of criteria for true managerial efficiency. Our empirical results demonstrated that the operational efficiency values after being adjusted for external environmental factors and statistical noise tend to be higher than the non-adjusted values. Our findings can help the banking management avoid resource misallocations, enhance banking efficiency and improve banking competitiveness.

This paper mainly focuses on researching and measuring the effects concerning the degree of internationalization (DOI) within the Taiwanese banking industry, with particular application of the scoring measurement by principal component analysis (PCA). The empirical results indicate that there exits an increasing trend for the DOI of Taiwanese banking industry as measured by FATA (each bank’s overseas assets over its own total assets), FETE (each bank’s overseas equities over its own total equities), FSTS (each bank’s overseas sales over its own total sales) and FBTB (each bank’s overseas facilities and operating units over its own total operating units). Under the Box-cox transformation, the DOI scoring index as percentage level (%) from 0 to 100 shows that the relevance of the variables are mostly above 50, indicating that the DOI of the observed Taiwanese banks are quite strong. Thus, the results support the existence and importance of the DOI for current Taiwanese financial institutions, while presenting complimentary and more realistic information regarding the degree of internationalization for Taiwanese banks. At the same time, providing substantial groundwork and adding value to future international management research and investigations that could help representatives of government and management decision makers to achieve better investment decision-making for business strategies and prompt international expansion.
