In the test of weak-form efficient hypothesis, this thesis used auto regression, auto correlation function and unit root three models, and got the basically same results. In the test of semistrong-form efficient hypothesis, this thesis used market model, index return model and constant mean return model three ways to estimate the normal return when making use of event study, and the results were also basically same.

其中，为求全面和比较，在对弱势有效市场的假说的检验部分，本文运用了自回归检验、自相关函数检验和单位根检验三种计量模型，检验结果基本一致；在对半强势有效市场假说的检验部分，本文运用了事件研究法，并在估计正常收益率时使用了市场模型、指数收益模型以及均值模型三种方法，估计结果也相对一致。

It was shown that when the production function was constant return to scale, the model became a A-K model; when the production function was increasing return to scale, the equilibrium point was unstable; when the production function was decreasing return to scale, the equilibrium point was a saddle.

结果发现：生产函数为规模收益不变时，模型简化为A-K模型；生产函数为规模收益递增时，均衡点为不稳定结点；生产函数为规模收益递减时，均衡点为鞍点稳定。关键词：数理经济学；经济增长；政府支出；生产效应

Since Leptokurtosis, skewness and fat-tail are always used to depict market risk, this paper introduces the improved Laplace distribution to risk management of stock portfolio. Empirical results show, improved Laplace distribution and asymmetric Laplace distribution are similar for estimating Leptokurtosis, while improved Laplace distribution is better for estimating skewness.In order to analyze the correlation between return distribution and volatility, the thesis uses ARCH-M Models to simulate the return series of China's Stock Market and developed markets ao as to discover the relation between investment return and time-varying risk.

对尖峰、厚尾、偏态的刻画有助于正确估计市场风险，本文将改进型Laplace分布引入到股票组合的风险管理中，实证结果发现，改进型Laplace分布和非对称Laplace分布对尖峰、厚尾的刻画效果接近；而非对称Laplace分布对负偏性考察不足，改进型Laplace分布的拟合结果能够准确地反映股指收益的负偏态，这也正是改进型Laplace分布相对于传统的非对称Laplace分布的优势所在。

Empirical results show, improved Laplace distribution and asymmetric Laplace distribution are similar for estimating Leptokurtosis, while improved Laplace distribution is better for estimating skewness.In order to analyze the correlation between return distribution and volatility, the thesis uses ARCH-M Models to simulate the return series of China\'s Stock Market and developed markets ao as to discover the relation between investment return and time-varying risk.

在分布和波动相关性建模方面，本文利用ARCH-M族模型来模拟我国股市和成熟证券市场的收益序列，以揭示股票市场中投资收益与时变风险的关系，并对我国股市和成熟市场的风险补偿系数以及投资者风险承受能力进行比较研究。

Investment return can be expressed as two parts: monitory return and non-monitory return.

投资的回收可以分为两个部分：金钱上的回收和非金钱的回收。

For the lack of return data in the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted, and forecasting is carried out by only using a few data. When the data amount reaches 50, the hidden quantitative relationship between sale quantity and return quantity is established by performing the transfer function-noise model. Its parameters are determined through model identification, parameters estimation and diagnostic checking. Then, forecasting return is accomplished.

回收初期数据缺乏，采用改进邻域系生成方法的GM(1，1)模型，实现了少量数据情况下的预测；回收数据累积到50个后，利用传递函数噪声模型构建了回收量和前期销售量之间的内在数量关系式，然后通过模型识别、参数估计、诊断检验确定了关系式的具体参数，进而实现了回收预测。

Firstly, reviewing and commenting on foreign and domestic literature about nonrecurring gains and losses; secondly, analyzing the definition and characteristics of nonrecurring gains and losses and the reason to form nonrecurring gains and losses; following, examining the research hypothesis using descriptive statistics and correlation analysis and regression of price and return model, furthermore optimizing the price model and return model through adding year variable and district variable which was divided according the return of the extraordinary items as dummy variables in the empirical research part.

文章先对国内外关于非经常性损益的研究现状进行回顾与述评；其次对我国关于非经常性损益的界定及其形成动机进行了分析；紧接着实证部分采用描述性统计、相关分析和运用价格模型和收益模型进行回归分析，对本文提出的研究假设进行检验，并加入年度虚拟变量和按照非经常项目利润率进行划分的区间虚拟变量对价格模型和收益模型进一步优化，使线性回归方程的拟合优度R2得到显著提高，利用优化后的模型对研究假设进一步检验。
