英文摘要:
      Basing on the theoretical analysis and test of institutional quality that impacts on commercial bank net interest margin, this article sets the institutional quality as a threshold variable to analyze the non-linear relationship between itself and commercial bank net interest margin. It recognizes three aspects as follows. Firstly, there is an obvious non-linear threshold effect between institutional quality and commercial bank net interest margin. During different institution level phases, institutional quality has a large impact on commercial net interest margin. Full sample data of commercial bank shows that they have a U-shape relationship, which means the impact becomes positive, inconspicuously negative, and obviously negative with the promotion of institutional quality. Secondly, although developed countries and developing countries both have this threshold effect, they present different basic characteristics. With the increase of institutional quality in developed countries, the impact is obviously negative with marginal efficiency. Moreover, with the increase of institutional quality in developing countries, the impact has a tendency of inconspicuously positive, inconspicuously negative, obviously negative with an increasing marginal efficiency of obviously negative impacts. Thirdly, the level of institutional quality in China is still very low, being a phase that institutional quality has impacts on decreasing commercial bank net interest margin. In the phase of interest rate marketization, the industrial structure upgrading and dispose of a plenty of "zombie" companies, the core of developing intermediary business promotion function and reducing the commercial bank service entity economy of net interest margin of commercial Banks is to perfect the laws and regulations, improve the efficiency of law enforcement and institutional quality.
