农机社会化服务采纳、禀赋差异与农村经济相对贫困缓解

进入以缓解相对贫困为重点的后扶贫时代，农村经济相对贫困问题仍不容忽视。农机社会化服务作为小农户与现代农业有机衔接的桥梁，对于推进乡村振兴战略和脱贫攻坚有序衔接具有重要作用。文章讨论的核心议题是农机社会化服务采纳如何缓解农村经济相对贫困，并尝试建立了“农机社会化服务采纳——禀赋差异缩小——农村经济相对贫困缓解”的理论分析框架。为此，文章首先对农机社会化服务采纳影响农村经济相对贫困的作用机制进行了理论分析，然后利用2750份河南省农户问卷调查数据，运用Logit模型，实证检验农机社会化服务采纳对农村经济相对贫困的影响，并通过替代核心自变量和变更样本的方法进行稳健性检验，运用PSM模型和IVProbit模型以及ERM模型进行内生性讨论，最后通过中介效应模型对其作用机制进行验证。结果表明，农机社会化服务采纳对农村经济相对贫困具有显著负向影响，缓解了农村经济相对贫困。考虑内生性后，结论仍具有稳健性。进一步的机制验证发现，农机社会化服务采纳通过缩小劳动力禀赋差异和技术禀赋差异，缓解农村经济相对贫困，劳动力禀赋差异缩小和技术禀赋差异缩小的中介效应占比分别为21.22%和7.36%。可见，应将完善农机社会化服务供需体系纳入农户相对贫困治理机制考虑范畴，引导农户从传统家庭化生产转向现代社会化生产，扩大农机社会化服务采纳范围；同时完善就业服务等相关配套体系以吸纳释放的弱劳动力，促进农户收入增长，缓解农村经济相对贫困。     

Deal characteristics and M&A performance: How do hospitality firms fare?

The global hospitality industry has experienced significant consolidation in the past several decades. While evidence in the general business literature suggests that the target firm shareholders gain instead of the acquiring firm shareholders, some studies in the hospitality industry have suggested that mergers and acquisitions (M&As) are also beneficial to acquiring firms. Using a comparative study design and a comprehensive sample over 41 years, we empirically examine whether M&As create more value in the hospitality industry than in other industries and whether certain deal characteristics may explain the potential performance differential. Overall, we find that M&As in the hospitality industry outperform M&As in non-hospitality sectors. When examining deal attributes, we find that relative size of target, cash method of payment, and an unlisted target are characteristics positively related to merger performance and help explain some of the performance differential. We contribute theoretically and empirically to the literature by demonstrating that industry and deal effects play an important role in M&A performance.     

我们为什么选择了社会主义市场经济

我们选择市场经济，是因为迄今为止的历史证明市场经济是可以富其国裕其民的。然而，我们所要的富裕，不是少数人的富裕，而是人民群众的共同富裕。不仅要富裕，而且必须是共同富裕的市场经济。因此，我们必须对市场经济进行改造，创造出我们自己的市场经济，这就是有中国特色的社会主义市场经济。该文遵循实事求是和历史唯物主义的原则，从市场经济旨在提高效率、社会主义则是坚持党的领导和社会公正、路径依赖和历史沿革体现了市场经济的中国特色等四个方面论证了中国共产党领导全国人民选择社会主义市场经济是一个具有历史必然性的伟大选择。这样的选择使得中国经济发展和人民富裕。     

Industry 4.0 technologies in the manufacturing sector: Are we sure they are all relevant for environmental performance?

This research contributes to the debate about the relevance of Industry 4.0 technologies in improving environmental performance in the manufacturing industry. We employed a qualitative–quantitative approach in which 19 Italian operations managers were interviewed and 260 managers responded to an online questionnaire. The effects of various technologies were ranked using ordinal regression. Comments and suggestions gave context to the quantitative results. Sensors, radio-frequency identification, artificial intelligence and analytics were found to be most relevant in improving environmental performance, whereas simulation software contributed moderately. Additive manufacturing, cobots, robots, automated mobile robots and automated guided vehicles had a negative effect, augmented reality had no effect and other technologies indirectly affected environmental performance. We also found a lack of knowledge and application as well as scepticism about technologies such as artificial intelligence and augmented reality. Finally, there was concern about the disposal of electrical and electronic waste produced by these technologies.     

The impact of the challenge and hindrance stress on hotel employees interpersonal citizenship behaviors: Psychological capital as a moderator

This study investigates the relationships between challenge and hindrance stressors and hotel employees’ interpersonal citizenship behaviors (ICB). The study also tests the moderating role of hotel employees’ psychological capital (PsyCap) on the aforementioned relationships. Data were collected from 213 U.S. hotel frontline employees. The results showed that both challenge and hindrance stress had a negative relationship with ICB. PsyCap was found to moderate both relationships. Implications for hospitality researchers and industry practitioners are discussed along with the limitations and suggested avenues for future research.     

科技服务业产出测算：指标确立、数据收集与未来预测

科技服务业产出测算是对科技服务业产出数据的统计与分析，加强科技服务业产出数据的规范统计和应用分析可为我国政府调整产业政策提供重要数据支撑。以科技服务业产出测算为研究对象，结合学者观点、国家标准及各级政府相关产业政策，提出将分支产业作为初始指标的横向统计思路，构建科技服务业产出测算指标体系。在数据收集方面，强调要做好“收”与“填”两个基本工作；在指标确立和数据收集基础上，进一步提出未来预测的两种方法，以此作为科技服务业产出数据预测的初步探索；提出应从统一数据统计标准、完善数据调查与公开制度、加强数据资源开发3个方面建立健全我国科技服务业产出数据测量与管理体制机制。     

中国金融系统风险溢出效应研究——基于溢出指数和波动溢出网络

文章基于溢出指数和波动溢出网络方法，从静态和动态分别度量我国金融系统不同子市场间的风险联动水平及变动趋势。研究结果表明，我国金融系统风险溢出效应整体水平较高，各市场间联动性较强；市场内部滞后效应大于市场之间溢出效应，两两有向溢出效应具有强不对称性；作为我国金融系统的风险中心，货币市场始终处于风险溢出方，但在金融危机时期，其对外风险溢出效应相对减弱，而大宗商品市场、资本市场、房地产市场等其余市场的风险溢出效应相对增强。值得注意的是，当前我国金融系统整体风险溢出水平较高，市场间风险相关性较强，需要进一步加强系统性风险的监测与防范。     

Perception value of product-service systems: Neural effects of service experience and customer knowledge

Digital trends in product-service system (PSS) development focus on developing win-win solutions for both companies and customers, particularly when considering human behavior issues. It is useful for the PSS provider to know the PSS value creation mechanism when customers are buying and utilizing a PSS, particularly in the service-dominant logic (SDL) and cognitive neuroscience perspective. This study solved the PSS implementation that satisfied the demands of both customers and manufacturers and the value cocreation mechanism during product and service configuration with the impacts of consumer learning and the service experience. The proposed neuroscience methodology is based on an ERP (event-related potential) experiment using PSS stimuli, representing the perception value creation process during customer decision making and the PSS configuration process. The effectiveness of the service experience is more important than customer knowledge during PSS value perception due to positive emotions with pleasant memories for the service experience and the conflicting cognition process of customer learning. The combination of service science and neurology may measure and observe human behavior and psychology through the brain science method and effectively solve the human factors in service science. The findings suggest a more objective and personalized understanding of PSS value perception, particularly the practical requirements of a resulted-oriented PSS and an application-oriented PSS.

Impact of shared history on customers’ service evaluations

This paper investigates how shared history affects customers' cultural and personal values and impacts their perception of services’ responsiveness and satisfaction in a high-contact service setting (retail banking) from two countries with a shared history (France & Lebanon). Data were collected from 171 French and 141 Lebanese bank customers. Findings reveal that both cultural and personal values moderate the relationship between responsiveness and satisfaction, and that their impact is independent of each other. Further, findings show that in countries with a shared history, existing cultural models in literature may not be detailed enough to explain cross-cultural differences and similarities.
