In a risk asset market,market makers often observe some partial signals of the value of a risk asset,including the total trading orders submitted by insiders and noisers.Under the assumptions of both profit maximization and market efficiency of pricing,we study the characteristics of insider trading market under the impact of two observing signals.It shows that much private information is released while expect profit of insider,order strategy parameter and market liquidity parameter are all keeping constant. 风险资产 内部交易 价值信号 市场定价的有效性 risk asset insider trading signal of value efficiency of market pricing 10.14188/j.1671-8836.2014.04.030 F830 国家自然科学基金资助项目（11161011） 2014-04-01 2021-04-01 4 60
