中国环境保护相关电价政策效应与资金机制

本文从电价政策优化视角,分析了环保电价与可再生能源电价的目标、补贴率变化,首次核算了两类政策的资金总额,对比评估了两类政策的资金规模、微观作用机制、资金机制和决策机制.结果发现,环保电价长年稳定,为燃煤发电行业污染治理资金提供了稳定预期,实现了污染物的快速减排;可再生能源上网标杆电价多次下调,激励企业技术进步的同时,助长了企业投机行为.微观作用机制上,环保电价刺激了燃煤发电企业治污技术进步、企业私人成本下降,但社会承担了较高的污染治理成本;而可再生能源电价政策促进了发电社会成本的下降.可再生能源电价资金传导机制更为刚性,但存在附加征收率不高、资金缺口大等问题,政策设计未做到激励相容.2015年环保电价与可再生能源电价补贴资金总额分别为767.97亿元（不含税）和429.1亿元（供给侧）.环保电价资金总额超过可再生能源电价资金总额,强化了燃煤发电成本优势,制约了可再生能源发展,不利于电力结构的清洁化.     

成渝城市群碳排放空间关联结构演化及影响因素

本文基于社会网络分析法（SNA）以及二次分配程序（QAP）方法,利用成渝城市群2005~2016年面板数据,对成渝城市群碳排放空间关联性及影响因素进行研究.结果表明：①成渝城市群碳排放空间关联性显著,呈现出复杂的网络结构形态,样本期内,网络密度由0.16增长至0.68,关联关系数从38个增长为162个.②重庆、成都、绵阳和南充等城市位于网络的中心地位,发出了较多的关联关系,同时发挥着中介作用.③碳排放空间关联网络被划分成为5个层级,层级结构整体较为稳定,然而第一层级与第二层级存在较为严重的断层现象.④空间距离、人口数量差异以及经济水平差异是碳排放关联性的主要驱动因素.城市间空间距离越近、人口数量与经济水平差异越大,越容易产生碳排放关联关系.

Speaking up and moving up: How voice can enhance employees' social status

A central argument in the literature on employee voice is that speaking up at work carries image risk. Challenging this assumption, we propose that voice can in fact positively affect how employees are viewed by others, thereby enhancing their social status. Using theory on status attainment and the fundamental social perception dimensions of agency and communion, we suggest that employee voice will result in higher status evaluations by increasing the extent to which an employee is judged as confident/competent (agency) and other‐oriented/helpful (communion). We conducted a survey study and two experiments to test these hypotheses. The results supported our predictions. Employees who voiced were ascribed higher status than those who did not, and this effect was mediated by judgments of agency (in all three studies) and communion (in two studies). These results highlight the implications of voice behavior for status enhancement within organizations.     

How does the social context fuel the proactive fire? A multilevel review and theoretical synthesis

The role of social context (e.g., leadership, team climate, and organizational support) in shaping employee proactive behavior has received considerable attention and has been investigated across multiple forms of proactive behavior. However, the research has not been well integrated. In this review, we adopt a multilevel approach to synthesize what is known about how social context factors influence employees' proactive behavior, as well as what mechanisms underpin these effects. Our analyses show that leader‐, team‐, and organization‐related social context factors mainly influence employee proactivity through shaping “reason to,” “can do,” and “energized to” states (i.e., proactive motivational states) via individual‐, team‐, and cross‐level processes. That has been most frequently investigated is the effect of the discretionary social context, particularly leadership, on proactive behavior. We also review the interaction effects between social context factors and other factors on employee proactive behavior and found inconsistent support for the motivational‐fit perspective that stimuli with the same directions enhance each other's effect. We offer a research agenda to advance theoretical insights on this important topic.     

Being trusted: How team generational age diversity promotes and undermines trust in cross‐boundary relationships

We examine how demographic context influences the trust that boundary spanners experience in their dyadic relationships with clients. Because of the salience of age as a demographic characteristic as well as the increasing prevalence of age diversity and intergenerational conflict in the workplace, we focus on team age diversity as a demographic social context that affects trust between boundary spanners and their clients. Using social categorization theory and theories of social capital, we develop and test our contextual argument that a boundary spanner's experience of being trusted is influenced by the social categorization processes that occur in dyadic interactions with a specific client and, simultaneously, by similar social categorization processes that influence the degree to which the client team as a whole serves as a cooperative resource for demographically similar versus dissimilar boundary spanner–client dyads. Using a sample of 168 senior boundary spanners from the consulting industry, we find that generational diversity among client team members from a client organization undermines the perception of being trusted within homogeneous boundary spanner–client dyads while it enhances the perception of being trusted within heterogeneous dyads. The perception of being trusted is an important aspect of cross‐boundary relationships because it influences coordination and the costs associated with coordination. © 2015 The Author Journal of Organizational Behavior Published by John Wiley & Sons Ltd     

Navigating uneven terrain: The roles of political skill and LMX differentiation in prediction of work relationship quality and work outcomes

Drawing from social/political influence, leader–member exchange (LMX), and social comparison theories, the present two‐study investigation examines three levels of LMX differentiation (i.e., individual‐level, meso‐level, and group‐level LMX differentiation) and further tests a model of the joint effects of political skill and LMX differentiation on LMX, relative LMX, and employee work outcomes. In Study 1, we used data from 231 employees and found support for the interactive effect of political skill and individual perceptions of LMX differentiation on LMX quality. We also found partial support for the moderating role of individual‐level LMX differentiation on the indirect effects of political skill on self‐rated task performance and job satisfaction via LMX. In Study 2, we used data from 185 supervisor–subordinate dyads and examined both meso‐level and group‐level LMX differentiation via a multilevel moderated mediation model. Results supported the moderating role of group‐level LMX differentiation and group mean LMX on the indirect effects of political skill on supervisor‐rated task performance and contextual performance/citizenship behavior as well as job satisfaction via relative LMX. Overall, the results suggest that politically skilled employees reap the benefits of LMX differentiation, as they enjoy higher absolute LMX and relative (i.e., to their peers) LMX quality.

Perceived social impact,social worth,and job performance: Mediation by motivation

This study was designed to test the relationship between perceived social impact, social worth, supervisor‐rated job performance (1 month later), and mediating effects by commitment to customers and work engagement. The hypotheses were tested with structural equation modeling analysis in a field study with 370 customer‐service employees from bank, retail, and sales positions. Results confirm that perceived social impact is associated with better job performance and that this relationship is mediated by work engagement. Furthermore, results support a second mediating mechanism in which perceived social impact and social worth are associated with engagement through affective commitment to customers. Finally, it was found that engaged employees are rated as better performers by supervisors 1 month later. This study supports the motivational approach to performance and highlights the role that interactions with customers may play in motivating service employees. Practical implications are discussed by highlighting the need to consider the social dynamics in service contexts. Copyright © 2015 John Wiley & Sons, Ltd.     

Considering connections between Hollywood and biodiversity conservation

Cinema offers a substantial opportunity to share messages with a wide audience. However, there is little research or evidence about the potential benefits and risks of cinema for conservation. Given their global reach, cinematic representations could be important in raising awareness of conservation issues and species of concern, as well as encouraging greater audience engagement due to their heightened emotional impact on viewers. Yet there are also risks associated with increased exposure, including heightened visitor pressure to environmentally sensitive areas or changes to consumer demand for endangered species. Conservationists can better understand and engage with the film industry by studying the impact of movies on audience awareness and behavior, identifying measurable impacts on conservation outcomes, and engaging directly with the movie industry, for example, in an advisory capacity. This improved understanding and engagement can harness the industry's potential to enhance the positive impacts of movies featuring species, sites, and issues of conservation concern and to mitigate any negative effects. A robust evidence base for evaluating and planning these engagements, and for informing related policy and management decisions, needs to be built.
