在最早的城市规划者看来，这样做能让人们重新认识到他们对雅典城市设计蓝图的伟大构想。从Plaka的旧城区开始，穿过哈德良拱门（Hadrian's Arch）直至Psiri区，不计其数的客栈和饭店都开在那里。

And the evaluation effects of China's Stock Market's volatility by different ARCH models from different point of view are compared. In addition, by using two mixed distribution models, the leptokurtosis and fat-tail of stock return are examined. Based on the above analysis, an improved Laplace distribution model is proposed. Furthermore, the root generating non-Gaussian return distribution of the stock market ? is expounded from the perspective of both economy and capital market.

首先分别从分布和波动性模型出发，研究中国股票市场收益分布特征与波动性特征：从ARCH族模型出发，考察了中国股票市场波动性的异方差、集群性、杠杆效应以及长记忆性特征；从两个混合分布模型出发，结合随机模拟考察了收益分布的尖峰、厚尾和偏态特征，并提出了改进型LapJace分布。

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。

After discussing the non-linear characteristic of the investment risk series, the thesis investigates several forecasting methods for non-linear risk series including AR model, ARCH model and neural network model.

本文在探讨了证券投资风险时间序列非线性特征的基础上，研究了包括AR模型，ARCH方差补偿型预测模型和神经网络预测模型在内的各种非线性风险预测方法以及组合预测方法。

In this paper, ARCH effects and serial correlation of stock returns are tested.

本文检验了我国股市的 ARCH效应和序列相关性。

In the empirical analysis part, statistical descriptions on the sample funds are made firstly, which show that the actual distribution of each sample fund"s daily net value return possesses the characteristic of leptokurtosis. So it is necessary to add student T distribution and GED to capture such leptokurtosis characteristic other than normal distribution. Secondly, ARCH test shows that there exists volatility clustering in each sample fund"s daily net value return, so GARCH related models should be used to describe such volatility clustering characteristic.

实证分析部分首先对样本基金进行统计描述，得出其收益序列均存在尖峰厚尾特征，不服从正态分布，因此有必要在下面的VaR计算中加入T分布和GED分布来捕捉这种尖峰厚尾特征；并且经ARCH检验后得出收益序列存在明显的波动聚集性的特征，因此可以选择GARCH类模型来描述这种特性，经过模型筛选，得出最适合我国开放式股票型基金的收益波动性模型为GARCH(1，1)模型。
