The important role played by the Chinese commercial banks in the development of China’s economy has made the government and banking regulatory authority concerned about the performance of these banks.Indeedthe stability of the banking sector has attracted greater attention since the financial crisis of 2007-2009. The principal objective of this study is to investigate the inter-relationships between profitability and stability in the Chinese banking industry. Using a sample of Chinese commercial banks over the period 2003-2013, the study examines the inter-relationships under an auto-regressive-distributed linear model. Both Z-score and stability inefficiency were used as measures of stability, while Return on Assets (ROA) was used as the indicator of profitability. Different types of Generalized Method of Moments (GMM) estimators including difference GMM, one-step system GMM, two-step system GMM as well as two-step robust GMM were used. In order to the check the robustness of the results, alternative econometric techniques were used, such as ordinary least square (OLS) estimator, between effect estimator, as well as fixed effect estimator. The results show that higher insolvency risk/lower bank stability leads to higher profitability of Chinese commercial banks and also that higher profitability leads to higher bank fragility.

This paper investigates the determinants of commercial bank profitability in oil and non-oil countries of the Middle East and North Africa (MENA) region using data from 11 countries over the period 2004–2014. Since banks are under no obligation to fill reports to Bankscope database, irregular reporting banks are omitted from the sample and the model is re-estimated using only regular reporting banks, and a comparative analysis between total banks’ sample and regular reporting banks’ sample is provided. Using the two-step system GMM and fixed effects models, the results indicate that credit risk is negative and highly significant when irregular reporting banks are omitted from the sample, particularly in the non-oil group, unlike the oil countries case, which indicates that adding irregular reporting banks to the sample could lead to bias in some estimated coefficients if they constitute a considerable percentage of the total banks’ sample. Diversification is a key determinant for profitability in oil countries. No enough evidence to support the impact of financial inclusion and financial openness on bank profitability. In addition, the global financial crisis has significantly affected bank profitability in oil countries. Several policy implications are provided to the bank management to follow based on each country group.
