This paper presents the portfolio selection problem of two-attribute money and creates a model of portfolio selection based on two-attribute money, which can both contain the existing portfolio models and overcome the above-mentioned deficiencies. A series of new concepts is put forward, such as, holding wealth, obtainable wealth, short-term utility function, short-term expectation-variance utility function, state-expectation-variance utility function, short-term expectation-variance utility curve, long-term expectation-variance utility curve, margin utility contribution force, additional contribution force, profit-risk exchange rate and optimal portfolio expansion curve; The state-expectation-variance analytical method is developed from the expectation-variance analytical method; A set of systematic theories concerning two-attribute portfolio selection is thus established.

本文提出了两属性货币的证券组合选择问题；创建了既能包含现有证券组合选择模型又能克服上述两点不足的两属性证券组合选择模型；提出了持有财富、可获财富，短期效用函数，短期期望—方差效用函数、状态—期望—方差效用函数，短期期望—方差效用曲线、长期期望—方差效用曲线，边际效用贡献力，附加贡献力，收益—风险替换率，最优证券组合扩展线等一系列新概念；把期望—方差分析方法发展成状态—期望—方差分析方法；建立了两属性证券组合选择模型的一套系统的理论。

Thisthesis begins with calculating the practical contribution rate of FDI to GDP and theemployment from 1994 to 2005, to analyze the contribution trend in those years, anddraws the conclusion-the increase of capital compose in FDI , the change of theforeign investment way and the improper government action in sorbing foreigninvestment have do harm to the domestic employment.

本文从计算1994年至2005年间中国实际利用外资金额对各年GDP和就业的贡献率入手，通过对相应折线图的走势趋势分析得出结论——近12年里，由于外商直接投资有机构成提高，外商投资方式转变以及政府招商引资存在失控等原因，导致FDI对就业的实际拉动作用并不显著。

The introduction of quark delocalization can be viewed as taking into account either the contribution of excited configurations or the distortion of individual baryon due to mutual interaction, its characteristic is to allow the six-quark system to choose the favorable configuration by its own dynamics automatically; Various quark models extended linear or quadratic confinement potential for 3q system to 6q system directly. Due to the nonlinearity of QCD, quark-quark interaction in color singlet may be different from that in non-color singlet. For example, the contribution of three-gluon exchange to one baryon is different from that to two baryon singlets, and so on.

引入夸克蜕定域效应，既可以看作是考虑了具有较高能量的激发组态的贡献，也可以看作是考虑了重子不碰撞过程中发生了畸变，其特点是让夸克体系自动选取最有利的组态；以往的QCD模型总是将哈密顿量直接从单重子系统推广到双重子系统，但QCD理论是一个非线性理论，处于色单态的两个夸克间的相互作用可能不同于处于非色单态的两夸克间的相互作用。
