中文摘要：

信贷管理是商业银行经营管理的核心内容，包括信贷规模管理和信贷合同管理两个方面，加强信贷规模管理和信贷合同管理是商业银行精细化管理的重要组成部分。在当前中央银行加强对商业银行规模控制以及实施新的《商业银行资本管理办法》的背景下，采用VAR方法和情景分析法实证分析了规模约束下和资本充足率约束下的信贷管理问题。结果发现：第一，规模约束直接影响商业银行的信贷规模，其中存款准备金率比存贷款利率对贷款规模影响显著，但存在4个月的时滞；第二，资本充足率约束直接影响到商业银行的信贷合同签订比例，按照新的资本管理办法，已签未贷合同需要增加资本金以覆盖其风险。

The research found that： first, size constraint directly influences its credit scale, and the deposit reserve ratio and lending rates have significant impact on the size of loans, but have the different effect of the time delay about 4 months. Second, the constraint of capital adequacy ratio directly affects the proportion of credit contracts signed by banks, and according to the new capital management approaches, the unfunded loan contracts need more capital to cover the risk than before.
