This study analyses bank efficiency in Vietnam from 1999 to 2009. We use a unique data sample that allows us to capture the development of the Vietnamese banking sector over the last decade. We apply an advanced methodological approach introduced by Simar and Wilson (2007) to examine bank efficiency in Vietnam. An integral part of the analysis is to explore the determinants of bank efficiency. The results indicate that large and very large banks are more efficient than small and medium sized banks with small banks having the lowest efficiency scores in the system. We also argue that banks with large branch networks and those that have been in existence for a long time are less efficient than other banks.

The purpose of this paper is to examine the degree of concentration and efficiency in the Vietnamese banking system using the structural model. We apply the concentration ratio

This study is conducted to investigate the impact of corporate social responsibility (CSR) on supply chain management (SCM) and financial performance, and the effect of SCM on financial performance through the mediate role of corporate reputation and customer loyalty. In addition, the study tests the moderate role of firm size and the ratio of export products in the relationship between SCM and financial performance. The research sample is 389 Vietnamese garment and textile firms by collecting through survey questionnaire. The results show that corporate social responsibility has a positive impact on SCM and financial performance and SCM has a positive impact on financial performance. However, firm reputation and customer loyalty do not have any mediate role in the relationship between SCM and financial performance. Firm size and export product ratio play a moderate role with statistical significance in the relationship between SCM and financial performance.

Purpose This paper aims to examine the market structure of Vietnam’s banking sector during 1999-2009, which is after the introduction of the two-tier banking system, using the non-structural (Panzar–Rosse) model. Design/methodology/approach The authors consider a more comprehensive range of specifications, in terms of a greater number of environmental covariates and different dependent variables, than in the previous applications of this model. Further, this is the first study that uses lagged input prices (to avoid endogeneity), excludes assets (to avoid specification bias) and includes a lagged dependent variable (to avoid dynamic panel bias) in such a study of the Vietnamese banking system. Findings The authors find that the Vietnamese banking system operates in monopoly. Originality/value The main contribution of this paper is to determine the market structure in the recent period after the Vietnamese banking system was transformed into a less centralised, two-tier system. This study is the first to uniquely identify the market structure of this developing economy’s banking system (using data only for Vietnam and not observations from other countries) in a post-transition period.
