专利实物期权定价的蒙特卡罗模拟方法及其改进技术

专利作为现代企业重要的无形资产,对企业募集发展资金、扩大收益回流、形成竞争优势发挥着巨大的作用,因此专利定价问题也成为现代企业管理决策中的重要内容.本文基于专利的实物期权特征,运用蒙特卡罗模拟方法对专利的实物期权定价问题进行研究与探讨.首先,分析探讨专利投资项目的决策过程及其实物期权特征;在此基础上,建立专利定价的实物期权蒙特卡罗模拟模型,并引入对偶变量技术用以提高蒙特卡罗模拟的效率;最后,以生物医药企业专利定价为例进行实证模拟.研究结论认为,引入适当方差减少技术的蒙特卡罗模拟则成为专利实物期权定价的一种有效的分析方法.     

Galileo系统L1P与L1F信号间干扰的分析

在L1频段上,Galileo系统的授权服务信号L1P和开放服务信号L1F共用中心频点1 575.42 MHz,它们的功率谱部分重叠,相互之间存在干扰。通过仿真研究L1P和L1F信号间的 干扰,对它们的干扰系数、载噪比衰减值进行了详细分析,找出了决定这两种信号间干扰大 小的主 要因素。仿真结果显示,L1P信号受到来自于L1F信号的最大干扰为0.002 dB,来自于CD MA干 扰的最大值为0.26 dB;L1F受到来自于L1P信号的最大干扰几乎为0 dB,来自于CD MA干扰的最 大值为0.604 dB。这表明,CDMA干扰是主要干扰源,L1P和L1F信号间的干扰可以忽略。 这主 要受益于L1P信号采用余弦相位的BOC调制,L1F信号采用CBOC调制,使这两个信号的功率谱 重叠部分大大减少,从而干扰系数很小,大大减小了它们间的干扰。

A supportive architecture for CFD-based design optimisation

Multi-disciplinary design optimisation (MDO) is one of critical methodologies to the implementation of enterprise systems (ES). MDO requiring the analysis of fluid dynamics raises a special challenge due to its extremely intensive computation. The rapid development of computational fluid dynamic (CFD) technique has caused a rise of its applications in various fields. Especially for the exterior designs of vehicles, CFD has become one of the three main design tools comparable to analytical approaches and wind tunnel experiments. CFD-based design optimisation is an effective way to achieve the desired performance under the given constraints. However, due to the complexity of CFD, integrating with CFD analysis in an intelligent optimisation algorithm is not straightforward. It is a challenge to solve a CFD-based design problem, which is usually with high dimensions, and multiple objectives and constraints. It is desirable to have an integrated architecture for CFD-based design optimisation. However, our review on existing works has found that very few researchers have studied on the assistive tools to facilitate CFD-based design optimisation. In the paper, a multi-layer architecture and a general procedure are proposed to integrate different CFD toolsets with intelligent optimisation algorithms, parallel computing technique and other techniques for efficient computation. In the proposed architecture, the integration is performed either at the code level or data level to fully utilise the capabilities of different assistive tools. Two intelligent algorithms are developed and embedded with parallel computing. These algorithms, together with the supportive architecture, lay a solid foundation for various applications of CFD-based design optimisation. To illustrate the effectiveness of the proposed architecture and algorithms, the case studies on aerodynamic shape design of a hypersonic cruising vehicle are provided, and the result has shown that the proposed architecture and developed algorithms have performed successfully and efficiently in dealing with the design optimisation with over 200 design variables.     

用基尼系数衡量我国收入公平的局限性探讨

文章认为,基尼系数在衡量我国收入公平问题存在的局限集中表现在基尼系数自身存在、衡量收入公平和我国收入差距特殊性三个方面。基于此,要结合对居民主观性评判起影响作用的因素和科学的理性统计数据两方面对我国收入公平问题做出符合实际的科学判断。     

住房价格与城镇居民收入分配差距关系研究——基于26个大中城市的实证

收入分配差距增大与住房价格快速增长,是我国经济新常态下需解决的两大问题。从住房价格与收入分配差距的关系入手,厘清两者之间的互动机制,利用2003-2012年26个大中城市相关数据,构造基尼系数与住房价格的面板数据回归模型。实证结果显示,住房价格对基尼系数的影响是正向的;基尼系数对住房价格的影响亦为正向的,但其强度要大于住房价格对基尼系数的影响。同时,研究发现城镇化率、GDP以及第三产业的发展状况等因素亦对住房价格与收入分配差距造成显著地影响。因而在城镇化推进过程中,依据住房价格与收入分配差距的互动关系,应考虑将房地产调控政策与收入分配政策相结合,以求解决房价上涨与收入分配差距拉大这两大问题。

Regional capital mobility in China: Economic reform with limited financial integration

This paper assesses the changes in the regional capital mobility in China during the period of economic reform in 1978–2008 by employing a panel time varying coefficient (TVP) model. This approach is much more suitable to model China's evolution in the regional capital mobility than a standard structural break model as China's reforms took place gradually and were often implemented over several stages. Using the TVP model, we find that (1) China's provincial capital mobility demonstrated a moderate improvement over the sample period, but worsened temporarily between 1994 and 1997. This is probably due to the government's effort to combat inflation which reduced the investment and transfers to regions; (2) regions with the most developed and least developed provinces experienced higher degree of capital mobility improvement than those in the middle.
