Foreign‐based competition and corporate diversification strategy

Since the mid‐1980s U.S. domestic firms have faced significant increases in foreign‐based (i.e., import) competition as reductions in barriers to international commerce have resulted in markets and industries becoming increasingly global. Despite the growing and widespread importance of foreign‐based competition, the influence that such competition may exert on corporate diversification strategy is a question largely overlooked in the strategic management literature. This paper examines the impact of foreign‐based competition in a firm's core business on both the level and nature of a firm's diversification strategy at the corporate level in a panel dataset of U.S. firms over the period 1985–94. Our findings provide the first evidence that increased foreign‐based competition is indeed a statistically significant factor explaining both the reduced business‐level diversity and the increased strategic focus of U.S. firms that has been widely perceived over the past two decades.

Managing customers as human resources in service organizations

On-site service encounters blur the organizational boundary between employees and customers. The strategic trade-offs involved in having customers on-site, and the HRM practices that can influence the satisfaction and performance of customers within the organization, are described. Central points include the HRM practices that foster a climate for service and that provide customers the role clarity, ability, and motivation they require to contribute to service production and delivery.     

人民币实际有效汇率变动对我国木质家具出口贸易影响

汇率是一个国家进行国际经济活动时最重要的综合性价格指标。在经济全球化这一新形势下,出口贸易作为带动经济增长、合理配置资源、引进先进技术和设备及经营理念的有效手段,对促进我国经济迅猛发展具有重要作用。基于迅速发展的我国木质家具出口贸易,汇率变动对其影响越发显著,因此认清这一影响以规避汇率风险则势在必行。     

中国绿色创新指数的分布动态演进与区域差异

研究目标:编制中国绿色创新指数,考察各区域指数的分布动态、区域差异及空间收敛特征。研究方法:建立绿色创新指数评价体系、采用时空极差熵权法赋权指标,利用世界知识产权组织绿色专利清单在线检索工具和采用爬虫技术检索、匹配、汇总国家知识产权局绿色专利数据,采用社会网络分析法(Social Network Analysis, SNA)测度绿色技术创新辐射力,采用Kernel估计分析绿色创新分布动态演进,采用Dagum基尼系数分解东中西绿色创新空间差距来源,采用空间杜宾模型考察绿色创新空间β条件收敛特征。研究发现:我国整体及东中西各地区绿色创新水平均呈总体上升趋势,源于绿色技术创新能力、绿色技术创新辐射力与绿色创新制度支撑力三者“携手并进”;绿色创新水平较高的城市集中分布于经济发达地区并具有较高行政级别特征,北京、深圳、上海、广州及主要省会城市稳居前列;我国整体及东中西地区核密度图均呈现“曲线右移、峰值先升后降、宽度收窄后扩大”的特征;东中西区域内部及区域间差异均呈逐渐下降趋势;绿色创新存在空间β条件收敛效应,且俱乐部收敛特征也较为显著,但在不同空间权重矩阵、不同地区样本中收敛速度存在差异。研究创...     

Tourist satisfaction and beyond: tourist migrants in Mallorca

This exploratory study analyses the role of tourist experience, especially tourist satisfaction, in subsequent migration from the UK to the municipality of Calviá, Mallorca, Spain. An overview and commentary is provided of theory relating to both tourist satisfaction and migration. Through a series of elite interviews, in‐depth micro‐studies and a questionnaire, which provides a small quantitative component, it is established that the motivation given by tourist satisfaction can be recognised as a key catalyst for migration. Classic migration motivations cannot be entirely discounted, and the migration decisions are multi‐stage through time. But tourist satisfaction—and particularly the two satisfaction components of performance and emotion—is especially relevant in the micro‐perspective of migration decision‐making.

Bubbles and crises: Replicating the Anundsen et al. (2016) results

This paper both narrowly and widely replicates the results of Anundsen et al. (Journal of Applied Econometrics, 2016, 31(7), 1291–1311). I am able to reproduce the same results as theirs. Furthermore, I find that allowing for time‐varying parameters of early warning system models can considerably improve the in‐sample model fit and out‐of‐sample forecasting performance based on an expanding window forecasting exercise.     

战场环境中的电波传播模型优化选择方法

针对战场级的复杂电磁环境仿真过程中涉及到全频段覆盖、环境影响、仿真速度要求高等问题,提出了一种综合考虑用频装备、环境信息和模型自身特点的电波传播模型选择方法。该方法首先通过频段对用频装备及电波传播模型进行划分,再结合环境信息中降雨量、海拔、植被覆盖率、气候类型、导电特性等参数进行综合分析,最终得到传播模型的优化选择方案。在典型作战场景仿真应用中,该方法为传播模型的合理选择提供了思路,保证了仿真的精度,同时也为电磁环境仿真中传播模型本地化提供了依据。
