The dissertation begins with the further discussion attributions of the economic contract , and comparing the economic contract with the ordinary economic contract and financial instruments, I think that the derivative financial instrument is an economic contract essentially, and has all the common characters owned by the economic contract, so we should establish the accounting for derivative financial instrument on the executory contract, otherwise the accounting for the derivative financial instrument will lose the basis of the accounting theory.

本文共分四部分：本文首先对衍生金融工具的经济属性进行了较为深入的探讨，并将其与一般经济合约和基本金融工具进行了比较分析，认为衍生金融工具本质上是一项经济合约，具有所有经济合约所具有的共性，衍生金融工具的会计处理应建立在对履行中合约的会计处理基础之上，否则对衍生金融工具的会计处理就会缺乏理论基础。

Comparisons between market performance under auction mechanisms and that under market maker mechanisms are made in terms of liquidity, stability, efficiency and transparency. The comparative results show that certain price formation mechanics integrated with specific market environment can affect market performance. The results of the test that is used to verify the liquidity of security market in China indicate that current price formation mechanics can provide the securities market with better liquidity. But the fixation of the minimum changing price lowers the liquidity of the market factitiously and close call auction mechanisms result in increased price fluctuation and price manipulation. Through the analysis on the competitive strategy of securities market, the objects and principles of the design of price formation mechanisms are established.

本文推导出了竞价机制和市商机制下证券市场的均衡价格，结果表明不同的价格形成机制对资产的真实价格有着不同的反映；从证券市场的流动性、稳定性、有效性和透明度等四个方面分别对竞价机制和做市商机制下的市场绩效进行了比较分析，结果表明一定的价格形成机制和特定的市场环境相结合就会对市场绩效产生不同的影响；通过对我国证券市场的流动性进行实证检验，发现当前我国证券市场价格形成机制能够为市场提供较好的流动性，但固定的最小变动价位人为地降低了市场流动性，并且封闭式的开盘集合竞价导致价格波动加大和市场操纵。
