贸易摩擦对中国钢铁产品出口影响的实证研究

随着中国钢铁产业快速的发展和世界经济环境的变化,涉华钢铁产品贸易摩擦日趋激烈。文章分析了中国钢铁产品出口贸易摩擦的概况,运用理论分析与实证分析相结合的方法,详细分析贸易摩擦对中国钢铁产品出口规模、出口市场结构以及国际竞争力的影响,对贸易摩擦的影响进行了总结:负面影响主要是出口规模的萎缩、限制相关企业的发展和提高出口贸易的成本,正面影响主要是促进贸易地理方向的多元化、产生优胜劣汰效应和促进技术创新。     

领导行为的马太效应：领导组织化身的调节作用

文章就组织行为领域领导行为的马太效应及领导组织化身的调节作用进行了具体理论分析和实证检验。以510名企事业单位员工为样本,探讨了领导行为的马太效应及其具体作用机制。研究发现：变革型领导(正性领导）行为对员工工作绩效具有积极效应,辱虐领导（负性领导）行为对员工工作绩效具有消极效应,两类领导行为均通过情感组织承诺的中介效应对工作绩效产生影响;同时,领导组织化身（SOE）在两类领导行为与情感组织承诺之间起着显著调节作用,使得领导行为的马太效应进一步凸显和放大。这表明了在管理实践中领导行为具有特殊重要性,应注意汲取其有益影响、克服其负面效应,并充分利用员工领导组织化身认知的调节作用大力提升领导行为的有效性。     

“中国梦”实现过程的中国经济总量和人民生活水平预测

文章分析了“中国梦”实现的三个阶段中,中国经济总量和人民生活水平将会发生的变化。文章预测：按实际汇率换算,2021年中国经济总量将超越美国成为世界第一经济大国,此时中国的人民生活水平将达到当时的世界平均水平;2049年中国的人民生活水平将达到世界高收入国家90%的生活水平;2065年中国的人民生活水平将达到最发达国家的生活水平,进而全面实现几代中国人梦寐以求的中华民族的伟大复兴。     

Sustainability winners and losers in business-biased cocoa sustainability programmes in West Africa

In cocoa farming forestland is a production factor. Cocoa planting is easiest and production costs are lowest in tropical forest. Historically, therefore, once forestland has been exhausted in a given geographical area planters tend to diversify into other production systems to avoid the poverty (induced by increasing factor cost) of post-forest cultivation. In modern times however cocoa planters exist in a value chain and post-forest diversification could threaten multinational companies relying on rural planters for their raw material. In 2014 ten of the world’s largest chocolate multinationals combined, with more than $500 million in funding, to introduce a cocoa sustainability scheme called CocoaAction. In principle, CocoaAction and similar sustainability schemes sponsored by western multinational chocolate companies are interventions to empower cocoa planters and planting communities in West African countries. But in practice, as this article will show, these schemes are a response to diminishing returns in cocoa-producing communities and the prospect of diversification, and the resulting projection of a shortage in raw material. There are signs that diversification away from cocoa will be beneficial to cocoa planters and their communities. Cocoa sustainability schemes are therefore designed for the benefit of multinational chocolate companies and at the expense of diversification in West African countries.     

A proposed configurable approach for recommendation systems via data mining techniques

This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage.     

Hotel environmental management initiative (HEMI) scale development

Owing to a lack of construct reliability and validity of environmental management measurements, advancements in understanding hotels’ environmental management practices have been somewhat limited. The goal of this paper is to propose a uniform and parsimonious scale that captures Hotels’ Environmental Management Initiative (HEMI) with the most common three dimensions in the hotel industry: environmental resource conservation efforts, environmental policy and training, and environmental public relation efforts. After the refinement of the initial items, the scale was confirmed with cross-cultural data obtained from full-time hotel employees in two Asian countries. The twenty-one item HEMI scale demonstrated a satisfactory level of content, convergent, discriminant, cross, and criterion-related validity. The proposed HEMI scale will serve as a useful tool for future hospitality scholars who would like to further explore the impact of hotels’ environmental management initiatives on employees’ attitudes and behaviors toward the environment and their environmental performance.     

The effect of economic policy uncertainty on China’s housing market

This study examines the relationship between economic policy uncertainty (EPU) and housing price at the macro-level in China as a developing country. The empirical evidence indicates that EPU has a leading effect on China’s housing market. In general, the housing market is prosperous when economic policy is stable and there is a positive relationship between housing price variation and EPU, which means housing market risk grows under unstable economic policies in this developing economy. Moreover, economic policy variation affects low-amplitude changes in housing prices. A variation of policy uncertainty enhances the risk premium of the housing market. By contrast, the level of EPU influences high-amplitude changes in housing prices, which reflects the trend of EPU dominating China's housing market.     

On equity market inefficiency during the COVID-19 pandemic

We show that during the weeks following the initiation of the COVID-19 pandemic, the United States equity market was inefficient. This is demonstrated by showing that utility maximizing agents over the time period ranging from mid-February to late March 2020 can generate statistically significant profits by utilizing only historical price and virus related data to forecast future equity ETF returns. We generalize Merton’s optimal portfolio problem using a novel method based upon a likelihood ratio in order to construct a dynamic trading strategy for utility maximizing agents. These strategies are shown to have statistically significant profitability and strong risk and performance statistics during the COVID-19 time-frame.
