上市公司使用金融衍生产品动机的实证研究

对中国上市公司的实证研究表明：公司规模越大，越倾向于使用金融衍生产品。大公司更加愿意使用衍生产品的原因主要在于规模效应，其具有信息和成本方面的规模经济。目前阶段中国上市公司使用衍生产品还处于初级阶段，公司使用衍生产品进行套期保值的数量和程度都不高，并且操作水平或风险控制存在问题，经常遭遇重大损失，多数公司还没有意识和能力进行有效的风险管理活动，因此西方财务理论的相关结论在目前中国并不成立。

At present, China＇s listed companies＇ use of derivative products is still at the initial stage ： the number and extent to hedge are limited ; there exist some problems in operating level or risk control so that some companies often suffer great losses; and most companies still lack the awareness and ability to effectively manage risks. Therefore, the related conclusions based on the Western financial theory don＇t prevail in.China.
