Integrating the two-stage of non-radial DEA model and BCG methods to evaluate the performance with strategic trajectory: a case study of securities industry

The 2008 sub-prime mortgage crisis in the United States brought many financial institutions to the brink of bankruptcy. Securities firms were not immune to such issues, given their prominence in the financial market. Consequently, evaluating the performance of securities companies’ post-recession is important when determining how to confront market-shaking macroeconomic problems. Consequently, this paper employs a non-radial model of data envelopment analysis (DEA) to measure the performance of revival on Taiwan’s securities industry. The research findings suggest that Tachan Securities (TCS) outperformed its peers in the operational period immediately after the global financial crisis, while Capital Securities (CAPITAL) is the best performer in the profit-making period. This paper applies the Boston Consulting Group (BCG) Matrix to analyze strategic positioning and trajectory on the basis of the efficiency value of the two-stage of non-radial DEA model. In order to validate any variances between the efficiencies of different stages after the global financial crisis, this paper conducts non-parametric statistical analysis to examine the variances in the efficiency values of the single-stage and the two-stage model. Finally, the purpose is to understand the impact of the post-crisis environmental variables on the efficiency of the securities industry. The empirical findings can serve as a reference for industry management on the assessment of operating performances and profitability by the characteristic of radial efficiency. Decision-makers in the industry may also refer to the findings as a benchmarking tool for the evaluation of business performance after the global financial crisis.
