乡村数字化转型对耕地绿色利用效率的影响机制及门槛效应研究

研究目的：科学探究乡村数字化转型对耕地绿色利用效率的影响机制,为推进乡村数字化转型赋能耕地绿色生产提供理论依据。研究方法：非期望产出SBM模型,Tobit回归模型和面板门槛回归模型。研究结果：（1）中国耕地绿色利用率均值由2011年0.628上升至2021年0.845,年均增幅2.17%,空间上呈现“东部、西部、中部”和“粮食主销区、产销平衡区、粮食主产区”依次递减格局;（2）乡村数字化转型水平均值由2011年0.127增长至2021年0.259,年均增幅10.49%,空间上呈现“东部、中部、西部”和“粮食主销区、粮食主产区、产销平衡区”依次递减非均衡格局;（3）中国乡村数字化转型对耕地绿色利用效率具有显著促进作用且存在区域异质性,东、中部地区乡村数字化转型的促进作用较西部地区更为显著,粮食主产区和产销平衡区较粮食主销区更为显著;（4）乡村数字化转型水平越过门槛值0.261时,对耕地绿色利用效率促进作用呈现边际效应递减的单门槛非线性特征。研究结论：区域间应联通数字赋能耕地绿色利用的合作共享网络、扩大数字技术对耕地利用环境污染的缓释效应和衔接耕地利用主体数字化耕种需求,是实现耕地绿色利用的长效驱动路径。     

不确定环境下企业战略变革主导逻辑新范式

企业战略变革是不确定环境下企业“做大做强”和“永续发展”的重要生存法则。而战略变革主导逻辑范式作为企业战略变革问题研究的核心与关键，在传统范式受到挑战的新形势下，呼唤新的战略变革逻辑范式。本文在对战略变革主导逻辑研究的相关概念与思维观念界定的基础上，构建了“战略变革主导逻辑范式分析框架”，并具体提出了“战略先应式”、“战略反应式”、“战略后应式”与“战略因应式”四种战略变革主导逻辑范式。     

Sustaining Collusion Via a Fuzzy Trigger

Probability theory is the standard economic representation of uncertainty, although it is not always an accurate one. Fuzzy logic is an alternative representation that does not require individual beliefs regarding the explicit functional form of uncertainty. This paper applies fuzzy logic to an oligopoly trigger pricing game. The fuzzy trigger pricing game reverses the standard cyclical price war prediction; collusion-sustaining price wars are most likely to occur during times of high demand. The fuzzy model also predicts that markets with relatively volatile prices are more likely to undergo collusion-sustaining price wars. The predictions are consistent with available empirical evidence.

Scale development for the practices involved in creating value propositions in the exhibition industry: Service-dominant logic with a mixed-methods approach

Building on a mixed-method approach, this study examines the practices engaged in creating value propositions in the exhibition industry from the perspective of service-dominant (S-D) logic, which regards the offering of value propositions as service innovation and an essential prerequisite for value cocreation. Consequently, a five-factor structure with 40 measures underlying the practices of offering value propositions is developed and validated. The extant tourism literature on the meetings, incentives, conventions, and exhibitions (MICE) industry mainly examines value cocreation issues while overlooking the concept of value propositions. This study contributes to the S-D logic literature by extending the theoretical understanding from value cocreation to value proposition. The findings of this study present important dimensions and attributes that are involved in creating value propositions for service innovation. Exhibition service providers can use these findings as a blueprint for service innovation project management and as a checklist for assessing their innovation competency.     

西藏封建农奴制度走向灭亡的历史逻辑

西藏封建农奴制度脱胎于吐蕃灭亡的纷争分裂格局中,以农奴主对农奴的残酷剥削为主要表现形式,以政教合一制度为最显著特征,以宗教对农奴的精神钳制为主要控制手段。自公元10世纪形成到公元13世纪确立,在上千年的历史长河中,西藏封建农奴制度经历了萌芽形成期、发展鼎盛期,虽然在一定时期内推动了西藏经济社会的发展,但后期愈发成为西藏发展进步的桎梏,最终随着西藏民主改革走向了灭亡。西藏封建农奴制度走向灭亡有其必然的历史逻辑,即落后的社会制度,如果固守不变、排斥变革,就必然落后于时代,也注定被人民推翻、被历史埋葬。

Employees as Active Consumers of HRM: Linking Employees’ HRM Competences with Their Perceptions of HRM Service Value

Recognizing the importance for companies of having high‐quality employment relationships with employees, previous studies have sought to explain the variability in employees’ perceptions of HRM service value. However, most of these studies view employees as inactive in employment relationships and, therefore, do not consider whether employees’ own attributes affect their perceptions of HRM service value. In accepting the alternative notion that consumers create value “in use,” the current study regards employees as active consumers of HRM practices, and so examines the extent and way in which employees’ HRM competences (i.e., knowledge, skills, and abilities) explain the variability in HRM service value. Based on data collected from 2,002 employees in 19 companies in the Netherlands, a positive relationship has been found between employees’ HRM competences and their perception of HRM service value, albeit one that is mediated by the perceived quality and nonmonetary costs of HRM services. The main implication of our findings is that employees should be seen as active agents in employment relationships who, through coproducing and consuming HRM services as well as leveraging their knowledge and skills, influence the value of HRM services and have the potential to increase or undermine the outcomes of the employment relationship. © 2015 Wiley Periodicals, Inc.     

由发誓达至互信建立的内在机制——人类社会中的发誓行为及其博弈分析

发誓是人类社会生活中常见的一种言语行为现象，其出现源自于信任的不足。发誓的一般结构包括发誓人、发誓对象、发誓内容、发誓约束。发誓的目的是通过发誓使发誓对象相信发誓内容，使发誓内容成为双方的公共信念，继而建立互信，从而使他们在博弈或后继互动中获取最大收益。这是建立社会信用的一种微观路径。由发誓建构互信的博弈机制是发誓人的发誓态度应当导致发誓人与发誓对象选择不同的策略，且他们的偏好或策略选择具有一致性。此外，他人在场见证发誓能够增强发誓人与发誓对象之间公共信念的强度，这是一种辅助的反反悔机制。     

The Strategy of Combining Products and Services: A Literature Review

This article provides the analyses of the academic literature on offering a combination of products and services. Trend analyses were performed from 1995 through the end of 2016 on the various parameters such as journals publishing this type of research, changes in the use of keywords, citation frequency, and research contribution from different authors, disciplines, and nations. The analyses presented a clear trend that research in combining product and services accelerated after the year 2000 indicating a focus on research in this area in the 21^st century. This highlights many emerging trends in this area.
