An Empirical Study on the Performance of Commercial Banks in Guangdong-Hong Kong-Macao Greater Bay Area Based on Relational Network DEA Model

摘要

In the context of global economic financialization, building Guangdong-Hong Kong-Macao Greater Bay Area into a world economic center with strong guiding and radiation force cannot be separated from the support of financial system. As an important part of the financial market, commercial bank's operating performance reflects the performance of the entire financial market. This paper uses relational network DEA model based on series system to measure the operating efficiencies of 20 major commercial banks in Guangdong-Hong Kong-Macao Greater Bay Area and evaluates the performance of commercial banks in the area to give some useful suggestions. The results show that the overall operating efficiency of the commercial banks in the area is not high. The pure technical efficiency of fund raising is relatively low compared to fund utilization, but the two stages have good correlation validity. The low technical efficiency of the system is mainly caused by the low pure technical efficiency. Within the area, there are significant differences in efficiency among the three regions-Guangdong city cluster, Hong Kong and Macao.
