Range Of Intermediate Business Of Commercial Banks, The Economic Impact Of Empirical Research

With financial market reforming, financial deepening and gradual opening up of domestic capital markets, domestic commercial banks are facing internal and external competitive environment is more intense. While domestic commercial banks are facing bottlenecks and provide economies of scale of differentiate products and services resulting from the gradual loss of competitive advantage, develop and improve the banking intermediary business and give full play to the middle of the business operations of the derivative based on the traditional and the modern financial market needs of connection characteristics advantage. As a result, domestic commercial banks with their own operating conditions to give full play to the middle of the business of derivatives, which based on the traditional business and the market demand for the characteristics of modern financial advantages of association, so as to develop and improve the banking intermediary business, the domestic commercial banks give full play to the scale based on the economic assets of commercial banks. This paper on domestic commercial banks since 1997, Based on the current economic situation; state-owned commercial banks and joint-stock commercial banks, and the scope of economic structure of development trends; By empirical analysis of the data, the paper reveals the commercial banks which develop intermediary business have the economic characteristics of intermediate business of commercial banks and the scope of economic factors.Main innovation of this paper is as the following:First, based on the theory which is the combination of econometric panel data fixed effects regression, with the Generalized Tran slog cost function model adding descriptions of variables R_C of qualitative information, while take the Industrial and Commercial Bank of China as the base group, and the remaining samples as a reference group to join Bank of dummy variables in order to select the reaction between the sample bank of non-control variables; Second, getting the clear structure of economies of scope, especially in the financial industry in connotation and commercial banks unique advantages,and we could confirm the concept of economies of scope from intermediate business on traditional business scale elasticity ratio and the production point of view of commercial banks; Third, Establishing generalized Tran slog cost function model of the intermediate business of commercial banks, we could develop the scope of empirical economic research. Fourth, this study related math theory, which based on the proven combination of economic sense to set out the rationality of the economic measure formula of scope which this paper uses. Fifth, this paper refers to the relevant economic mathematical literature, and gives the mathematical theories which can be used to measure economies of scope of bank development.
