بررسی معیار شرکت های تراست سرمایه گذاری تایوانی: مدیریت و دیدگاه بهره وری سرمایه گذاری

Through an additive efficiency decomposition (AED) approach in data envelopment analysis (DEA), we evaluate the management and investment efficiencies of Investment Trust Corporations (ITCs) in Taiwan for the period 2007–2011. Furthermore, the AED-DEA and a network-based ranking approach in DEA are jointly used to rank and identify ITCs that can be treated as benchmarks. Frontier projections for ITCs are also highlighted. In general, our results demonstrate that the sample ITCs have higher investment efficiency than the management efficiency. Foreign ITCs appear to be the most efficient ones as compared to local ITCs and financial-holding ITCs. Finally, we construct a competitive map to help mutual fund managers improve their operating performance, resource allocation, and investment strategy formulation.
