商业银行劳动效率及其影响因素研究——基于Translog要素需求函数的实证分析

Research on Labor Input Efficiency of Commercial Banks and the Determinants——An Empirical Analysis Based on Translog Factor Demand Function

从要素投入和公司治理结构这一微观视角出发,通过建立超对数劳动力需求随机边界模型,运用单阶段估计技术,评估中国商业银行的劳动力投入无效率,并对所有制、治理结构、市场结构以及其他影响因素进行实证分析。研究发现,我国商业银行整体劳动无效率除了在研究初期有较大降幅以外并未随时间的推移表现出明显的下降趋势,其中城市商业银行显示出最高的劳动效率,大型商业银行最低,但随着时间的推移,其差距日渐缩小。资产规模与劳动效率负相关,市场开放和改制上市起到了显著的促进作用,而外资参股则并无明显影响,意味着在金融自由化的大背景下,中国银行业改革的方向主要在于进一步开放市场,减少对内资银行政策上的照顾和行政性干预,规范市场竞争行为,完善公司治理机制和提高资产质量。

From the micro scope of factor input and corporate governance structure, and by establishing a translog labor demand stochastic boundary model and employing single stage estimation technique, the authors evaluate the inefficiency of labor input of commercial banks in China, and the other determinants such as ownership, governance structure, and market structure. Research shows that labor inefficiency of Chinese commercial banks did not show a clear downward tendency with time goes on in addition to a sharp decline at the initial stage of the research. City commercial banks show the highest level of labor efficiency, while large scale commercial banks have the lowest efficiency, but the gap becomes smaller with time passes by. Labor efficiency is negatively correlated with asset size, it significantly promotes market opening, system reform and stock issuing, but is has no significant influence on foreign equity participation. Based on this, the authors propose the reform orientation of Chinese commercial banks under that background of financial liberalism.
