效用

The contributions of this dissertation are as follows.(1) It firstly applies the fife cycle theory to make typology and research for Chinese market system;(2) It finds the "Six curves constitute the throat" phenomena of Chinese household consumption structure macro-indicator, and thus contribute to structural theory literature;(3) It explanatorily forecasts Chinese household consumption trend by firstly using worst orbit forecasting method of reverse thinking;(4) It firstly proposes the concept of "educational urbanization development", and thus provide new angle to research urbanization in China;(5) It firstly proposes the hypothesis of "Deceleration Effect" of credit consumption on gini coefficient, i.e., income gaps can be filled by credit consumption.

本文创新之处在于：首次运用生命周期理论对中国市场经济体制进行划分和研究；发现了中国居民消费结构广义指标的"六线呈咽"现象，为结构理论研究增添了新的内容；首次逆向思维的运用最差运行轨迹预测方法，探索性的进行中国居民消费结构趋势预测；首次提出"教育型城市化发展的概念"，为研究中国城市化，提供了新的思路；首次提出信贷消费对基尼系数"熨平效用"的假设，即收入水平带来的差距可以用信贷消费的方式"熨平"。

Using the dynamic programming approach, an explicit solution to the value function of the optimal portfolio problem is obtained by the HJB equation, and the optimal investment strategy is given.

在风险投资服从Heston模型的假设下，研究了幂效用函数的最优投资组合问题，利用动态规划方法通过HJB方程得到最优投资组合价值函数的显式解，并给出最优投资策略。

By applying this exponential utility function, portfolios to suit a variety of different investors can be obtained.

并且因为效用函数的引入，因此可以求得满足不同风险偏好投资者的资产配置。

This article tries to research the externalization and dynamic externality of producer services together.

本文尝试将生产性服务业的外部化和动态外部性结合在一起研究，其中，外部化的理论基础主要是传统的效用函数理论，动态外部性的理论基础主要借用Lucas(1988)和Romer(1986、1990)的内生增长理论。

This study develops a whole new aspect of contingent-claim model for hedging the catastrophe risk. We describe the framework of the new hedging strategy - catastrophe swap - as detail as possible and compute the exchange amount of CAT swap contract by Monte Carlo Simulation. Last but not least, this article reveals the most powerful back-up, net cash flow and utility comparison between different strategies, to prove the practicability and favorableness of our catastrophe swap model.

本篇论文将设计一个跨期性理赔的避险模型来处理巨灾风险，於后文将会仔细地介绍这个全新的避险策略「巨灾交换契约」其模型的建构概念以及方式，并由蒙地卡罗模拟法计算出所需的交换数额，最后，针对三种不同的巨灾风险处理来进行数值分析，藉由比较其「净现金流量」和「期望效用」来验证该巨灾交换契约模型的可行性与有利性。

New findings suggested that it will be highly effective.

Established stochastic model for user strategy selections to study the game with finite population. According to the expectation utilities of user, produced invasion and fixation rates to quantify selection pressure during the repeated games. Finally, detailed the effects of population size on selection scenario under fixed utility matrix through example.
