Specially, based on risk - metric and factor variables, the author discusses multi - factor asset pricing model. in theoretical analysis, the author attempts to release the assumption of index ' s random walk, proves a portfolio selection model suitable for the linear index level moreover, based on assets un - exchangeable, the author brings forward asset pricing models for b - shares, h - shares and non - circulated - shares. the author also brings forward multi - factor asset pricing model based on risk - metric indices, such as coefficient of beta, standard variance, standard semi - variance, average absolute deviation, value at risk, and factor variables, such as circulated market equity, exchange ratio, short - term historical return
在理論分析時，作者嘗試放鬆指數水平滿足隨機遊走過程的假設，推導出指數水平呈線性趨勢的資產組合選擇模型；此外，作者基於資產不可交易這一假設，提出了b股、 h股和非流通股等情形的資產定價模型，並基於系數、標準差、標準半方差、平均絕對離差和風險價值等風險度量指標以及流通市值、換手率、短期歷史收益率等因素變量提出了四因素資產定價模型。 -
In this thesis, abundant statistical data are contained, two methods are employed to give a positive analysis on the elasticity of demand ( eod ) of i & e in china during the period from 1990 to 2001 from the following three aspects : firstly, regression analysis is applied to calculate the average eod of the general i & e. generally speaking, the export is rich in price eod while the import has a poor one. in addition, the absolute value of the sum of these two kinds of elasticity is higher than 1, which accords with marshall - lener condition and proves that devaluation of rmb should be helpful to improve the trade balance. suggestion is further provided such as cutting off producing cost of export, improving technology and implementing strategy of import substitution to improve trade balance
本文運用豐富的統計數據資料、兩種方法、從三個層次實證分析了1990 - 2001年我國進出口商品的需求彈性：首先，運用回歸分析法計算總體進出口商品的平均彈性，得出我國出口商品總體富有價格彈性，而進口商品總體缺乏價格彈性，進出口需求價格彈性之和的絕對值大於1 ，符合馬歇爾?勒納條件，人民幣貶值有助於改善貿易收支的結論，並提出降低出口商品生產成本、提高生產技術水平、實施進口替代戰略來改善貿易收支；其次，運用彈性定義法逐年計算約100種主要出口商品和約50種主要進口商品的總體需求價格彈性，對其結果進行分析，進一步驗證了前述結論；再次，運用彈性定義法逐年計算農產品、鋼鐵、汽車、醫藥等五大類八種商品的進出口需求價格彈性，根據其不同的分佈狀況，聯系實際經濟情況，提出相應的匯率、價格及產業政策以改善貿易收支。 -
The calibration of flow model is acceptable with average rms of 0. 7m, residual mean of - 0. 045 m, average absolute mean error of 0. 1 m and normalized rms value of 2. 3 %. the contour map of the simulated heads, elaborated acceptable model calibration compared to observed heads map
模型結果中，均方差為0 . 7m ，平均誤差為- 0 . 045m ，平均絕對誤差為0 . 1m ，標準均方差為2 . 3 ，模擬地下水流場與實際觀測地下水流場基本一致，說明所建立的數值模型符合該地區的實際水文地質條件。 -
One is combined with the maximum average error criterion and the mean square error criterion, and the other is combined with the absolute value average error criterion and the mean square error criterion. theory analysis shows that the two new search methods have less computational complexity than that of the non - optimal method
提出了兩種替換原有均方誤差最小準測的方法，分別是最大平均誤差與均方誤差最小準則相結合的搜索標準，以及絕對值平均誤差與均方誤差最小準則相結合的搜索標準。
