以2006年至2011年16家上市银行的数据为基础,对比了三种分析商业银行规模经济的计量模型——Cobb-Douglas模型、Translog模型以及本文提出的完全互补模型。综合三个模型的结论,银行业规模不经济可归结为两个来源:一部分源自生产效率不高,另一部分源自成本控制不力,且后者是导致规模不经济的主要原因。 相似文献

This paper presents the results of fitting a scaled translog restricted profit function to ‘pseudo’-data formed by repeated runs of a large linear programming model of domestic and international refining. The translog approximation is designed to estimate the marginal cost of producing eight petroleum products given the amounts of each product demanded and the price of crude oil. We test the model against out-of-sample data from the refinery model and historical data. The model is used in the US Department of Energy's Annual Energy Outlook forecasting system. 相似文献
