本土技术创新、外国技术溢出与我国制造业贸易竞争优势互动性的实证分析

技术创新与国际贸易之间存在着一种互动关系,在开放经济系统中,一国技术创新能力的提高不仅取决于本土技术研发,也受到外国技术溢出的影响。通过实证分析得出:改革开放以来,我国本土技术研发与贸易竞争优势间形成了良性的正向互动关系,但外国技术溢出却与我国制造业贸易竞争优势的形成有明显的双向负面关系。

Moral Agency,Profits and the Firm: Economic Revisions to the Friedman Theorem

The paper reconstructs in economic terms Friedman’s theorem that the only social responsibility of firms is to increase their profits while staying within legal and ethical rules. A model of three levels of moral conduct is attributed to the firm: (1) self-interested engagement in the market process itself, which reflects according to classical and neoclassical economics an ethical ideal; (2) the obeying of the “rules of the game,” largely legal ones; and (3) the creation of ethical capital, which allows moral conduct to enter the market process beyond the rules of the game. Points (1) and (2) position the Friedman theorem in economic terms while point (3) develops an economic revision of the theorem, which was not seen by Friedman. Implications are spelled out for an instrumental stakeholder theory of the firm. Dr. Sigmund Wagner-Tsukamoto is researcher in business ethics at the School of Management of the University of Leicester, UK. He holds two doctorates, one in social studies from the University of Oxford, UK, and one in economic studies from the Catholic University of Eichstaett, Germany. He has widely published on green consumerism and institutional economic issues that concern organization theory and business ethics theory. His publications include the books Understanding Green Consumer Behaviour (Routledge, 1997 & 2003) and Human Nature and Organization Theory (Edward Elgar, 2003).     

Marine Tourist Motivations Comparing Push and Pull Factors

This study examined the relationship between push and pull factors with regard to marine tourist motivations. The survey was distributed systematically to people intercepted at high-traffic locations in Seoul, South Korea. The results indicated that escape push motivations are closely related to static activity pull motivations, while novelty push motivations are more strongly related to active activity pull motivations. These relationships may be partially explained by the push-pull framework of tourist motivations. These results imply that a marine tourist destination focusing on static activities should appeal to tourists who have escape push motivations, while a marine tourist destination focusing on active activities should appeal to tourists who have novelty push motivations.

非活跃市场环境下公允价值计量相关问题研究

公允价值并非只运用于活跃市场,非活跃市场是公允价值运用不可或缺的主要环境,活跃市场在很大程度上只是公允价值运用的特殊环境。美国FAS157《公允价值计量》没有系统考虑非活跃市场环境下诸多公允价值计量问题。深入研究非活跃市场环境下公允价值计量相关问题,并与基于活跃市场环境的公允价值计量框架进行对比和对接,有利于完善公允价值计量理论与方法体系,提高会计信息的决策有用性,加速实现我国与国际会计准则的持续全面趋同。     

一种非对称不变分布的混沌干扰源设计与干扰效果分析

提出了一种用于干扰数字通信系统的非对称不变分布的混沌干扰样式。基于混沌映射 产生均匀分布的混沌序列,经过相应非线性变换,得到了服从非对称不变分布的混沌干扰信 号 。与现有干扰信号产生方法相比,该方法易于模块化实现,可控性和可再生性好。理论分析 和仿真结果表明,相比于高斯分布干扰,满足Rayleigh分布的混沌干扰对QPSK和16QAM系统 具有更好的干扰效果。
