以贷款人同质为假设的传统信贷配给理论无法解释当前我国银行中普遍存在的低贷存比等信贷抑制现象,本文认为我国信贷市场存在国有垄断型与市场竞争型两类异质贷款人,以此为论证起点,分析异质风险偏好与目标函数下的信贷供给行为模型,发现国有垄断型贷款人的均衡供给小于市场竞争型这一信贷供给抑制的内生诱因,同时,我国固定存款利率制度与信贷市场寡头垄断型结构等外生因素加剧了供给抑制现象,最后,本文从理论意义上给出政策改进的方向。
The traditional theory of credit rationing based on the assumption of lender homogeneity can not explain the phenomenon of credit depreciation such as low loan-deposit ratio which is ubiquitous in China’s banks. This paper argues that there exist two types of heterogeneous state-owned and market-competitive lenders in China’s credit market, Using this as a starting point, we analyze the credit supply behavior model under heterogeneous risk preference and objective function. It is found that the equilibrium supply of state-owned monopoly lenders is less than the endogenous incentive of market competition, which is the credit supply repression. Meanwhile, the fixed deposit interest rate The exogenous factors such as oligopolistic structure of credit market and credit system exacerbate the phenomenon of supply restraint. Finally, this paper gives the direction of policy improvement theoretically.
