基于Nash均衡的专利战略分析     

陶锋 《科技管理研究》2010,30(19)

运用博弈论的思维方式和分析工具,研究在既定专利制度下的专利战略,通过专利战略的博弈分析,提出专利战略的组织行为策略应基于Nash均衡的理念;现代经济条件下,无论是技术创新、产品升级还是国际贸易,制定专利战略的均衡策略是组织行为的重要一环.  相似文献

大学生助学贷款的博弈分析   总被引：2，自引：0，他引：2  

李晓宁 《山西财经大学学报(高等教育版)》2007,10(1):68-71

助学贷款本是一项利国利民的政策,但这项政策却遭受了空前的信用危机。文章通过对学生和银行的行为进行博弈分析,认为纯粹靠道德等内在诚信来约束学生的还贷是无用的,必须建立起一套完整的外在诚信约束机制。文章还设计了助学贷款的“三维”被迫诚信机制,以明确助学贷款中政府、银行、贫困生家庭和借款学生的权责和义务。  相似文献

ABSTRACT

The objective of this study was to create a valid, self-reported, game-specific soccer competence scale. A structural model of perceived competence, performance measures and motivation was tested as the basis for the scale. A total of 1321 soccer players (261 females, 1060 males) ranging from 12 to 15 years (13.4 ± 1.0 years) participated in the study. They completed the Perceived Game-Specific Soccer Competence Scale (PGSSCS), self-assessments of tactical skills and motivation, as well as technical and speed and agility tests. Results of factor analyses, tests of internal consistency and correlations between PGSSCS subscales, performance measures and motivation supported the reliability and validity of the PGSSCS. The scale can be considered a suitable instrument to assess perceived game-specific competence among young soccer players.  相似文献   

Timescales for exploratory tactical behaviour in football small-sided games

The aim of this study was to identify the dynamics of tactical behaviour emerging on different timescales in football small-sided games and to quantify short- and long-term exploratory behaviour according to the number of opponents. Two teams of four professional male footballers played small-sided games against two different teams with a variable number of opponents (3, 5 and 7). Data were collected using a combination of systematic observation and a non-differential global positioning system (15 Hz). The temporal diversity and structural flexibility of the players were determined by calculating the dynamic overlap order parameter q, entropy and trapping strength. Analysis of the exploratory dynamics revealed two different timescales, forming a different metastable landscape of action for each constraint. Fast dynamics lasted on average a few seconds and consisted of changes in tactical patterns. The long timescale corresponded to the shared tasks of offence and defence lasting tens of seconds. The players’ tactical diversity decreased with an increasing number of opponents, especially in defence. Manipulating numerical imbalance is likely to promote changes in the diversity, unpredictability and flexibility of tactical solutions. The fact that the temporally nested structure of constraints shaped the emergence of tactical behaviour provides a new rationale for practice task design. The manipulation of numerical imbalance on the timescale of a few tens of seconds, on which the exploratory behaviour of players saturates, may help coaches to optimise the exploratory efficiency of the small-sided games.  相似文献

我国现有出版市场的博弈分析     

白琳 《山西师大学报(社会科学版)》2006,33(1):141-144

入世后的本土出版市场是一个充斥着理性冲突的博弈格局,政府、本土出版社与外资三方都有各自的得益要求。从博弈三方的策略分析,外资一般采取巨资涌入、内容为王、人才争夺、政策公关等策略;政府通常运用政策杠杆作为主要调控手段;本土出版机构常常是在政府与外资之间寻求可能而利益最大化的发展途径。这种合作策略的选择是典型的相互性决策,而均衡性决策才是最佳的市场选择。  相似文献
