This study develops a whole new aspect of contingent-claim model for hedging the catastrophe risk. We describe the framework of the new hedging strategy - catastrophe swap - as detail as possible and compute the exchange amount of CAT swap contract by Monte Carlo Simulation. Last but not least, this article reveals the most powerful back-up, net cash flow and utility comparison between different strategies, to prove the practicability and favorableness of our catastrophe swap model.

本篇论文将设计一个跨期性理赔的避险模型来处理巨灾风险，於后文将会仔细地介绍这个全新的避险策略「巨灾交换契约」其模型的建构概念以及方式，并由蒙地卡罗模拟法计算出所需的交换数额，最后，针对三种不同的巨灾风险处理来进行数值分析，藉由比较其「净现金流量」和「期望效用」来验证该巨灾交换契约模型的可行性与有利性。

The spot market supply and demand between the two sides in a future time on the commodities sell/buy the request because they were afraid that the arrival of the time when the price is not conducive to their own requirements, so willing to now the futures market price to sell/buy an equal number of futures contracts to lock in the cost of this behavior is hedging.

由于期货行情在一天内的波动幅度经常会很大，如果以"瞬间"的盈亏结果来作为对某方实施比如"强行平仓"的行为的话，极有可能一方面引发大量的交易纠纷，另一方面甚至导致整个交易根本就无法正常进行下去；所以交易所一般采取或在收市前的某个时间、或在次一个交易日开市前的某个时间作"资金结算"（此处用词可能不当，应该怎么定义记不太清楚了）；在规定的时间内，保证金不足的一方若不能及时将保证金予以补足、交易所才对其行使强行平仓的权力。

As a common rule,the classical hedging theories and methods calculate the optimal hedging ratio based on a portfolio including a hedged asset and certain hedging instruments,and don\'t consider risky elements of hedging and hedger\'s realistic requirements during the course of hedging.

The dissertation in depth analyzes the inner relationship between hedging and risk diversification, finds out that the relevance among prices or returns of different assets is the common basis for hedging and portfolio selection,and presents the notion of hedging portfolio selection referring to portfolio selection theory,which means that hedgers choose optimal hedging portfolio from a set of feasible hedging tools considering risky elements and hedger\'s real requirements during the course of hedging.

本文深入分析了套期保值与风险分散化思想的内在联系，指出资产之间价格的相关性是套期保值问题和资产组合选择问题的共同基础，提出应该在真正的资产组合选择理论意义上研究套期保值问题的研究思路，即在充分考虑套期保值过程中各种风险因素和套期保值者实际要求的基础上从可供选择的套期保值工具集合中选择最优套期保值组合，并称这种研究套期保值的方法为套期保值组合选择。

First of all, the valuation errors in TXO of the BS-IV model are the smallest among all volatility models. In the whole, the BS-IVmodel underprices the market value, BS-HV, BS-EV（EGARCH（1,1））and Ad hoc BS model overprice the market value respectively. Next, there exist the linear relationships between the valuation errors and moneyness in TXO mostly. At last, in view of hedging errors, the other thing being equal, the shorter is the maturity, the smaller is the hedging error.

本文的实证发现，在评价误差方面，整体而言，隐含波动性模型对买权及卖权的评价误差最小，隐含波动性模型之理论价格低估了市场价格；而历史波动性模型、EGARCH（1，1）模型及平滑后的历史波动性模型之理论价格则大多高估了市场价格；接著，在评价误差与金融特性关系方面，各波动性模型之评价误差与价内价外程度、股价指数报酬率、股价指数波动性、距到期日及无风险利率等因素，大多具有显著的线性关系。

In the literature, many static and dynamic hedgings are proposed to solve this hedging problem. Since dynamic hedging comprises more relocation opportunities than static one, it is usually superior to static hedging in terms of risk reduction.
