竞技武术对城市群众武术的影响及对策研究

采用文献资料调研、逻辑分析等方法，对由于长期受竞技武术训练模式的影响，使以武术为健身手段的城市人群在不断萎缩进行分析研究，并提出相应对策，以期对城市群众武术的发展提供有利的理论依据。     

A conceptual framework for evaluating designs for corporate innovation

Innovation is becoming mandatory for an increasing number of organizations in order to sustain competitive advantage. This paper explores how designs for corporate entrepreneurship fit within other dimensions of a strategy configuration. To do this, first, seven innovation-related problems are diagnosed. The specific problem patterns arising in three representative approaches to corporate innovation efforts (internal research and development, joint ventures, and acquisition) are discussed. Next, issues related to strategy configuration are examined. The problem-accommodating characteristics associated with specific environmental domain choices and with two routes to competitive advantage are proposed. Hypotheses that reflect the problem characteristics of innovation approaches with the problem propensities resulting from organizational choices of domain and competitive advantages are offered. Specific directions for future research, as well as the practical applications of these concepts, are discussed.     

伙伴关系--企业竞争优势的新来源

伙伴关系成立的原因在于以伙伴关系为纽带可以建立新的企业优势,它具有以产权关系为纽带形成的"紧密型"企业所不具备的优点.企业通过建立合作伙伴关系,以形成低成本和差异化竞争优势.     

我国丝绸出口贸易的经济分析

我国丝绸出口贸易的 "显示"比较优势指数呈逐年下降的趋势,但其数值一直保持在17以上,说明我国的丝绸出口与其他出口商品相比仍具有很大的竞争优势;我国丝绸出口的相对价格弹性系数为-0.3825,属于低弹性的商品.降低丝绸出口价格,不但无益于丝绸出口量的增加,反而会引起出口创汇额的明显下降,引起丝绸"出口贫困"现象的产生.稳定我国丝绸出口价格,是我国蚕丝业和丝绸贸易稳定发展的正确选择.     

类生产函数企业价值链管理模型研究

本文从价值链的一些本质特征出发,借鉴生产函数的原理与形式,提出了一种新的价值链模型——类生产函数价值链管理,证明了类生产函数的一些重要性质,论述了此模型对企业价值链的管理与优化过程。最后进行了实例分析,分析过程及结果表明,该模型能够较好地实现价值链的优化与管理。     

企业诚信与竞争优势的关系研究--基于苏州等六地188家企业的实证调查

本文在综合和提炼了企业诚信与竞争优势的相关理论基础上,将企业诚信分为三个维度,分别是信用水平、品牌、利益相关者信任;将竞争优势分为销售业绩、发展潜力、管理绩效三个维度.本文分析了企业诚信三维度与竞争优势三维度之间的相关和回归关系,研究结论有利于企业诚信建设.     

关于正义的互惠性概念

互惠性是正义的固有特性 ,它涉及对正义本质和基础的认识 ,但长期以来 ,道德学家们对互惠性的理解并不一致。分析批判霍布斯、叔本华、康德和罗尔斯等人的观点 ,可以看出 :互惠性是正义制度下的一种人际关系 ,包含着平等性、合作性和协调性的特征。它是正义存在和贯彻的真正基础 ,是正义的一种独立特性。     

基于卓越伦理的竞争优势

本文提出了“卓越伦理”和“基于卓越伦理的竞争优势”概念,概括了拥有卓越伦理的企业具有超越自身利益的使命和目的、合乎伦理地对待利益相关者、实行伦理领导等三个基本特征。从“有价值”、“稀缺性”、“难以模仿性”三个方面,论证了卓越伦理已具备成为可持续竞争优势来源的条件,从而得出了卓越伦理是可持续竞争优势一个来源的结论。     

从后发优势视角看发展经济学的演化

从“后发优势”视角来理解和把握发展经济学的演进过程。从某种意义上说,发展经济学在很大程度上是随着对发展中国家后发优势及其对实现途径认识的不断深化而演进和发展的,其困境是由于未能找到将“落后”转变为“优势”的有效途径,其发展则是在不同思路的思想实验和发展实践中不断推进的。     

Semi-online scheduling with “end of sequence” information

We study a variant of classical scheduling, which is called scheduling with “end of sequence” information. It is known in advance that the last job has the longest processing time. Moreover, the last job is marked, and thus it is known for every new job whether it is the final job of the sequence. We explore this model on two uniformly related machines, that is, two machines with possibly different speeds. Two objectives are considered, maximizing the minimum completion time and minimizing the maximum completion time (makespan). Let s be the speed ratio between the two machines, we consider the competitive ratios which are possible to achieve for the two problems as functions of s. We present algorithms for different values of s and lower bounds on the competitive ratio. The proposed algorithms are best possible for a wide range of values of s. For the overall competitive ratio, we show tight bounds of ϕ + 1 ≈ 2.618 for the first problem, and upper and lower bounds of 1.5 and 1.46557 for the second problem. The authors would like to dedicate this paper to the memory of our colleague and friend Yong He who passed away in August 2005 after struggling with illness. D.
