Simulation and Research on Agent-Based Artificial Stock Market [PDF]

open access: yes, 2017
股票市场是一个复杂的动态变化系统,以投资者完全理性为假设前提的传统的金融理论往往难以解释股票市场的涌现现象,基于历史数据对股市的实证研究面临着很多困难。基于主体的人工股票市场是计算金融的核心研究领域,为我们研究股票市场的微观结构和宏观现象涌现提供了一条新的研究思路。 本文的主要工作是基于计算金融学多主体的建模方式,在参考中国股票市场的真实情况下,利用Java语言构建了一个贴近中国股票市场的人工股票市场。在人工股市的模型中设计了混合策略模型的交易者主体,并采用连续双向拍卖的价格形成机制 ...

The Diffusion of Digital Information Products with the Influences of the Bandwagon Effects and Network Effects:A Perspective of Complex Networks [PDF]

open access: yes, 2014
当今社会已经进入创新时代。作为企业的核心竞争力,创新对企业的生存和可持续发展具有重要意义。如果创新无法在社会上传播并被人们接受,即创新无法扩散,那么创新就无法实现其社会价值。创新产品扩散逐渐成为国内外学者和企业家们研究的热点。在创新产品扩散的过程中,特别是数字信息产品扩散的过程中,跟风效应和网络效应起到了不可忽视的作用。 为了体现消费者之间的交互作用,本文基于复杂网络视角,结合三度影响理论建立了跟风效应和网络效应的微观扩散模型,采用仿真的方法对数字信息产品扩散进行分析 ...
