An Empirical Study On The Effects Of Commercial Bank Transaction Costs To Efficiency

With the economic development, commercial banks play an important role and bear the important functions. The development of commercial banks affects the development of the economy as a whole, so there are never lack of the research of commercial bank. However, the domestic scholars rarely study on commercial bank transaction costs. Because commercial banks are different from general real economy sector, they bear the trading intermediary functions in social economy, so the transaction costs have a large proportion in the commercial banks. The change of transaction costs has an profound impact on commercial banks, so the study of commercial bank transaction costs has very important theoretical and practical significance. Before 100 years, in the article "the nature of the firm" Coase put forward the concept of transaction costs, and then many scholars studied the transaction costs, but academia community has not a clear definition. At the same time, due to the time transaction costs’unpredictable factors, there is a small amount of research about the transaction cost measure. When the paper do the research of commercial banking transaction costs, we try to give an scope of transaction cost in the commercial bank and calculates the average transaction cost commercial banks. Based on the completion of transaction costs measure of commercial banks, the paper try to study the relationship between the commercial bank efficiency and the transaction costs. This also provides certain theoretical support of improving our country commercial bank efficiency. The final conclusion of the paper is:(1) commercial banks gradually completed the shareholding system reform since 2004, the amount of transaction costs of the listed joint-stock commercial banks continues to grow, however the average transaction cost decline; (2) The relation between the efficiency of commercial banks with the average transaction cost、commercial banks non-performing loan ratio、the deposit-loan ratio is obvious. Specifically, the relation between the efficiency of commercial banks with the average transaction costs、 non-performing loans is negative, and with the commercial bank deposit-to-loan ratio is positive.The research idea and research method base on the path of "literature review-framework-empirical results-policy recommendations", and according to this path, this article is divided into five parts altogether. The first part is introduction, and it mainly include the paper selected topic background, research significance, research methods, innovations and shortcomings; The second part is the summary of the existing research, including the research of transaction, transaction cost and transaction cost measure research; The third part is the theoretical framework of this article, and it explain the theory of transaction cost measurement in the commercial bank, as well as give the commercial bank transaction cost measure empirical and result analysis; The third part is the research about the relationship between the commercial bank efficiency and transaction cost, including the correlation of logic, the influence mechanism and empirical analysis; The last part is the conclusion part of this article, and according to the conclusion, the paper gives the relevant policy recommendations. At the same time, I summarize the deficiency of this article.
