Chapter one of this text has recommended the foreign insurance to apply financial economy to the products pricing method of insurance company, but these methods have not explained how to determine the fair premium of the multiple-line insurance company .In order to solve many business line insurance company pricing problem, chapter two introduce an very important model in insurance company capital allocation field - MR capital allocation model, through deriving capital allocation formula and simulation analysis indicate MR model allocate multiple- line insurance company capital scientifically. In order to apply MR model to non-life insurance pricing, chapter three will extend MR model to introduce loss 3 and layer P . Since the premise of MR model is a certain market price of loss, the chapter four will use the risk-neutral probability transformation technique to get the market value of loss. Under lognormal distribution, we will use location parameter shift and proportional PH transformation to illuminate the technique. The final chapter combines the prior sections result to deduce out the fair premium formula, and apply it to price the catastrophe insurance.

本文的第一章介绍了国外保险业将财务经济学应用到保险公司产品定价的方法，但是这些方法都没有说明如何确定多业务线保险公司的公平保费；为了解决多业务线保险公司定价问题，第二章引入保险公司资本配置领域非常重要的一个模型—MR资本配置模型，通过推导资本配置公式及模拟分析表明MR模型科学地配置了多业务线公司的资本；为了将MR模型应用到非寿险公司的定价中去第三章扩展了MR模型，引入了损失β和层β的概念：由于MR模型的前提条件是有一个确定的损失市场价值，第四章利用风险中性转化方法获得损失的市场价值，在损失为对数正态分布的条件下，通过位置参数转化和比例危险转化方法给出了实例说明；第五章结合前几章的结果给出非寿险公司公平保费的定价公式，并运用它给出了巨灾保险价格的模拟分析。
