本研究旨在衡量俄羅斯銀行業競爭程度的變化,探討2003至2010年間,其銀行行為、政府政策和國際情勢對俄羅斯銀行業競爭程度的影響。本研究以非結構法的Panzer-Rosse模型為研究主軸,並輔以結構性指標來衡量俄羅斯銀行業的競爭程度,發現俄羅斯銀行業在2003至2009年俄羅斯的銀行市場大多處於獨占性競爭。但是2010年以資產標準化的總收入為被解釋變數時卻無法拒絕市場存在獨占力或銀行間存在聯合勾結的寡占之需無假設,可能與俄羅斯政府因應全球金融危機所作的政策調整有關。
為使結果更具可靠性,本研究排除可能影響檢定結果知極端值進行敏感性檢定,將可能對市場具有獨占力的俄羅斯最大的國有銀行Sberbank排除在樣本之外,結果2010年的俄羅斯銀行市場仍然存在獨占力。另外,考慮不同地區銀行密集度的不同,將研究樣本分成中央聯邦區與非中央聯邦區,結果發現在銀行密集度較高的中央聯邦區在2005至2009年為完全競爭,但是該地區2010年的銀行市場依然存在獨占力,而非中央聯邦區的競爭程度變化較小。相較於過去的文獻,本文發現俄羅斯銀行業在考慮利息收入與非利息收入之競爭程度有所不同,尤其在2008至2010年間的差異更為明顯,而俄羅斯銀行業的競爭程度在金融危機期間也確實因為採用的被解釋變數不同,致使兩者的H統計量與市場檢定結果呈現不一致的趨勢。 / This paper examines the degree of market competition in Russian banking industry by analyzing the impact of bank activity, government policy and international situation over the period of 2003-2010.We use the P-R model as well as concentration ratio and Herfindall-Hirschman Index to measure the competition in order to distinguish competitive behavior on market. Evidence is found that during the period of 2003-2009 the Russian banking industry is characterized as monopolistic competition. But in 2010, the market becomes monopolistic due to the change of government policy by global financial crisis.
To do our sensitivity analysis, we exclude the outlier that might influence the results such as Sberbank, the biggest state bank of Russia. But our results remain the same. Furthermore, this paper separates the region into Central Federal District and non- Central Federal District, and we find that market is perfect competition in Central Federal District in period 2005-2009, but monopoly still exists in 2010. Compared with the previous literature, this paper finds that some differences exist between the results when dependent variable is interest revenue and the result of total revenue, especially in period of 2008-2010.
