摘要: 本文对《商业银行资本充足率管理办法》实施以来我国银行在资本监管约束下的资本与风险调整进行了实证分析。本文将资本监管压力分为惩罚压力与预警压力,资本充足率低于监管要求的银行面临惩罚压力,而达到监管要求但与监管要求之差低于其资本充足率的一个标准差的银行面临预警压力。研究发现惩罚压力对银行资本与风险调整均没有显著影响,预警压力显著提高了资本缓冲不足银行的资本比例调整,对风险调整没有显著影响,显示出我国商业银行为达到资本监管要求,补充资本的同时又不放弃追求高风险高收益。进一步的,通过对资本补充机制的分析,发现银行较为依赖资本市场融资,内源性资本的内在激励和降低风险的约束机制尚未形成。

Abstract: This paper shows the empirical analysis of capital and risk adjustment of commercial banks under regulatory capital discipline enacted since 《Commercial Bank's Capital Adequacy Ratio Management Measures》in China. And also this paper investigates the capital and risk adjustment of commercial banks under regulatory capital discipline. Our empirical studies indicate that the punish pressure of capital regulation does not affect bank’s capital and risk level, while the warning pressure has a significant impact on capital-asset ratio in the banks which approach the regulatory capital requirement but do not have a sufficient buffer. We also show some empirical evidence on the role of IPO, allotment of shares, season equity offering and subordinated debt in bank capital adjustment.
