旅华英国游客O→D旅游客流动力机制研究

文章在分析目前客源地→目的地旅游客流动力机制相关研究理论现状与不足的基础上,提出了＂推—拉—阻＂旅游动力机制。然后,在10个热点旅游城市采用100分制6点等距量表,以537份旅华英国游客有效问卷数据为依据,对旅华英国游客来我国城市旅游的旅游动力中的推力因子、拉力因子、阻力因子及其权重进行了研究。研究结果表明,旅华英国客流旅游动力中主要有8大推力因子、9大拉力因子和7大阻力因子,推力在促动力中占44%,拉力在促动力中占56%,阻力相当于促动力的39%。     

也论区域旅游合作的动力机制——兼与靳诚等同志商榷

本文对研究者建立的一个区域旅游合作动力机制模型进行了分析,指出了其中存在的问题,提出了对区域旅游合作动力机制新的理解.本文将区域旅游合作的动力机制理解为区域基础条件和旅游市场对旅游企业或政府产生作用并促使他们采取合作行为的机制.     

黑色旅游发展动力机制及“共生”模式研究——以汶川8.0级地震后的四川为例

黑色旅游是一种情感性的旅游,强调大众对旅游客体的价值判断和情感倾向。近年来,黑色旅游因其独特的吸引力而受到众多旅游者追捧,现已成为广义休闲旅游中的一个重要组成部分。在分析黑色旅游内涵的基础上,对黑色旅游的动力机制进行了解析。同时,引入共生理论,并以四川灾区为案例对黑色旅游的"共生"模式进行了研究。希望能唤起人们对黑色旅游的关注,促进人们更科学地认识黑色旅游及其内部规律,同时也期望对四川震后旅游业恢复重建工作有所启示。     

动态规划在装备更新优化中的应用

运用运筹学中动态规划的理论和方法来解决航空装备更新问题,与传统的凭经验确定装备更新策略的方法相比,节约了成本,显著提高了军事效益,为科学制定装备更新策略提供了依据。     

动态能力核心构成及其功效模型探究

动态能力是一种新的战略分析框架。研究人员和经理人的一个根本问题是理解动态能力,即重新配置资源以应对动荡环境的经营能力。动态能力一直被视为抽象。动态能力的三大核心构成要素分别是学习与吸收能力、协调整合能力与创新能力。     

“十三五”期间我国经济——能源——环境系统变量发展预测

本文以动态可计算一般均衡模型为基础,2010年投入产出表延长表为基准数据,对“十三五”期间我国经济--能源--环境系统相关变量进行了预测。分析结果显示：“十三五”期间我国经济将实现新常态下的稳定适宜增长,GDP增速保持在65%左右,产业结构进一步优化,第三产业比重明显上升,第二产业明显下降。由于经济增长的原因,能源消费总量与碳排放总量依然较高,但能源消费结构进一步优化,碳排放强度明显降低,节能减排的形势依然比较严峻。     

Dynamic strategic groups: deriving spatial evolutionary paths

Recent theoretical developments in the domain of strategic groups, specifically those related to cognitive groups and strategic group identity, seem to suggest that strategic group membership is likely to be relatively stable over time and that firms in a strategic group co‐evolve. Yet appropriate data analytic approaches that use information about firms over time to identify stable strategic groups and their evolutionary paths have been lacking. To overcome such limitations, this research proposes a new clusterwise bilinear multidimensional scaling model that can simultaneously identify (1) the number of strategic groups, (2) the dimensions on which the strategic groups are based, and (3) the evolution of the strategy of these groups over time. Our discussion encompasses various alternative model specifications, together with model selection heuristics based on statistical information criteria. An illustration of the proposed methodology using data pertaining to strategic variables for a sample of public banks in the tristate area of New York, Ohio, and Pennsylvania across three time periods (1995, 1999, and 2003) identifies two underlying dimensions with five strategic groups that display very different evolutionary paths over time. Post hoc analysis shows pronounced differences in firm performance across the five derived strategic groups. This article concludes with a discussion of the implications of the findings, as well as potential future research directions. John Wiley & Sons, Ltd. Copyright © 2009 John Wiley & Sons, Ltd.

International Housing Markets and the U.S. Subprime Crisis

We propose a novel decomposition approach to study the degree of co-movement of international housing markets while distinguishing among different economic drivers. We find that the housing market variability for an average country was mainly driven by the common housing risk premium components during the years leading up to the 2007–08 subprime financial crisis. A decrease in the common housing risk premium was followed by a housing boom and economic expansion in the United States prior to the crisis. Our findings add to the understanding of the role of common risk factors across international housing markets before the crisis.     

Revisiting the role of the environment in the capabilities–financial performance relationship: A meta‐analysis

Within the capabilities‐based view of the firm, there is debate about the relative importance of ordinary and dynamic capabilities for firm performance and about the extent to which their performance effects are contingent on environmental conditions. We meta‐analyze 115 studies to investigate the relationship between both ordinary and dynamic capabilities and the financial performance of firms in relatively stable versus changing environments. The results suggest that the performance effects of both types of capabilities are positive and similar in magnitude. Environmental dynamism reinforces the effects of both ordinary and dynamic capabilities. Furthermore, the two types of capabilities are closely associated. Our findings provide support for a moderate capabilities‐based view of the firm, rather than one that considers dynamic capabilities as superior to ordinary ones.
