Abusive Supervision and Psychological Capital: A Mediated Moderation Model of Team Member Support and Supervisor-Student Exchange

Embedded in higher educational settings, this study examines the relationship between abusive supervision and psychological capital and the mechanism through which abusive supervision and team member support interact to influence psychological capital with supervisor-student exchange mediating the interaction with psychological capital. Data collected from 222 graduate students in six Chinese universities supports our mediated moderation model: abusive supervision negatively relates to psychological capital and supervisor-student exchange mediates the positive moderating effect of team member support on the relationship between abusive supervision and psychological capital. Theoretical and practical implications of these findings are discussed.     

对中国新型低碳技术扩散的实证研究与分析

研究了低碳技术中的一种新型技术——二氧化碳捕获与封存(Carbon dioxide Capture and Storage,CCS)技术在中国最近8年以来的扩散情况,选用2000—2008年我国CCS相关技术的研发存量和国外8个技术先进国家通过外国直接投资(Foreign Direct Investment,FDI)扩散的研发存量数据,对我国CCS技术进步的全要素生产率进行回归分析,探讨了CCS技术在中国扩散的情况及带来的影响。结果表明,我国的CCS技术取得了巨大的进步,这些进步主要来源于两方面:国外FDI的促进作用和国内研发创新的作用,并且国内研发创新的作用略大于国外FDI的作用。最后根据分析结果,提出了在我国通过技术扩散和创新发展CCS技术的政策建议。     

中国城镇居民储蓄的影响因素研究:基于三类储蓄动机的实证分析

本文用中国城镇居民1980-2007年的数据,检验了影响居民储蓄行为的三类动机,即生命周期动机、遗赠动机和预防性动机。结果发现这三类储蓄动机都对中国城镇居民的储蓄行为产生影响,其中生命周期储蓄动机是解释中国居民高储蓄率的重要原因,但收入分配差距扩大导致整个社会的遗赠储蓄增加,引起总消费不振。此外,由于居民面临的不确定性增加,中国城镇居民的预防性储蓄动机也随之提高。     

行业绿色增加值核算方法的讨论

绿色GDP核算需要行业绿色增加值核算作为基础,遵循平衡原则、权责发生制原则和市场原则。农业绿色增加值应是农业增加值减去属于农业经济活动所引起的资源耗减与环境降级,同时也包括大自然对农业所依赖的资源造成的影响与耗减。工业与建筑业绿色增加值应是工业与建筑业实现增加值扣除工业与建筑业经济活动造成的资源耗减与环境的降级。服务业绿色增加值主要是从增加值中扣除环境的降级。     

Buying while expecting to sell: The economic psychology of online resale

Consumer online resale is becoming increasingly common for transactions of secondhand goods. However, when accompanied by a preconceived intention to resell a product after using it, the initial consumer purchasing decision for self-use is complicated by the estimated resale value of that good. We applied the principles of mental accounting to develop and evaluate a new concept that may influence consumer resale and purchase intention: external resale reference price (ERRP). The study examines how online consumer sellers' economic psychology of buying affected their expectation of future online resale outcome. The results indicate that (1) consumers' awareness of future online resale potential can influence their purchasing decisions; (2) ERRP, which is mediated by the estimated resale return, can increase purchase intention; and (3) the effects of ERRP on purchase intention are moderated by online resale likelihood, but are minimal when consumers are aware that resale possibility is extremely low.     

理性经济人批判与国家理性行为体假说

该文基于理性经济人批判,提出符合时代要求与社会进步的"国家理性行为体"假说,即假设国家作为一个整体,国家行为必须要从事物发展的客观规律出发,综合权衡全体国民短、中、长期的利益需求及其可获得性,以均衡、稳定与可持续地增进全体国民福利最大化为目的。     

收获信任与温暖的新潮旅游群体——对沙发客的初步研究

源于欧美的沙发冲浪是一种新颖时尚的互助旅游方式。相比于传统的旅游模式,基于网络信任的沙发冲浪具有情感投入、体验充分、成本低廉等特点。借助ROST WordParser词频分析软件,通过对相关沙发客网站的文本内容进行分析,总结出沙发客旅游行为的50个高频词汇,并归纳为动机、感知、活动、交通方式、沙发城市、游玩地点等六大类目。研究发现,＂朋友＂和＂温暖＂在文本词汇中出现频率最高,结交朋友、扩展人脉是沙发客的主要旅游动机之一,受到热情接待、体会家庭温暖是沙发客的共同感知;＂联系＂、＂聊天＂、＂游览＂构成沙发客的基本活动;＂火车＂、＂搭车＂与＂公交＂组成交通方式的关键词汇;国际大都市＂上海＂、＂北京＂及风景如画的＂厦门＂、＂杭州＂成为热门目的地;＂景点＂、＂大学＂与＂公园＂是沙发客关注的游玩地点。     

R&D投入、技术创新能力与企业经济绩效间关系的实证分析

以浙江省312家制造企业为研究对象,采用回归分析方法,对企业R&D投入、技术创新能力与经济绩效之间的关系进行了研究。结果表明:R&D投入与企业经济绩效显著正相关;新产品产出能力和发明专利申请量在R&D投入与企业经济绩效之间起部分中介作用,其中新产品产出能力的中介效应明显高于发明专利;尽管R&D投入对实用新型专利和外观设计专利的申请量有显著的促进作用,但这两类专利申请量并不是R&D投入与企业经济绩效间关系的中介变量。     

Mean-variance hedging with oil futures

We analyze mean-variance-optimal dynamic hedging strategies in oil futures for oil producers and consumers. In a model for the oil spot and futures market with Gaussian convenience yield curves and a stochastic market price of risk, we find analytical solutions for the optimal trading strategies. An implementation of our strategies in an out-of-sample test on market data shows that the hedging strategies improve long-term return-risk profiles of both the producer and the consumer.     

Guilt, Shame, and Reparative Behavior: The Effect of Psychological Proximity

Research has paid scant attention to reparative behavior to compensate for unintended wrongdoing or to the role of emotions in doing the right thing. We propose a new approach to investigating reparative behavior by looking at moral emotions and psychological proximity. In this study, we compare the effects of moral emotions (guilt and shame) on the level of compensation for financial harm. We also investigate the role of transgressors’ perceived psychological proximity to the victims of wrongdoing. Our hypotheses were tested through a scenario based questionnaire on a sample of 261 participants. Analyses indicate that (1) guilt has a stronger effect on the level of compensation than shame; (2) psychological proximity influences the level of guilt, shame, and compensation; and (3) shame interacts with psychological proximity to predict compensation, whereas guilt mediates the relationship between psychological proximity and compensation.
