企业技术创新与企业经济绩效关系的探析

本文以总资产收益率和净资产收益率作为反映企业经济绩效的因变量,以研发密度、技术人员比率、资本支出率和专利作为反映企业技术创新的自变量,同时选用控制变量资产负债率（Debt）和企业规模（Size）进行回归估计,得出如下结论：企业研发密度、企业技术人员比率、专利授权数均与企业经济绩效之间存在正相关关系,资本支出率与企业经济绩效之间存在负相关关系。     

Positive psychological capital and emotional labor in Korea: the job demands-resources approach

This study examined the effect of organizational justice perception on service employees' positive psychological capital and the influence of positive psychological capital on surface and deep acting. Drawing on the job demands-resources (JD-R) model and the literature on positive work environment, the indirect effects of perceived distributive and procedural justice on surface and deep acting through service employees' psychological capital were hypothesized. Using data from 263 flight attendants of the largest airline company in South Korea, the results indicated that perceived distributive and procedural justice were positively related to service employees' psychological capital, which, in turn, fostered deep acting but not surface acting. Deep acting was negatively related to emotional exhaustion, while surface acting showed a positive relationship. Emotional exhaustion, in turn, increased turnover intention. This study offers contributions to our understanding of positive psychological capital and implications for emotional labor in service management. Limitations and future research directions are discussed.     

前摄型人格、工作形塑与员工创新绩效 ——基于冗余资源的调节作用

基于人格特质和资源基础理论,构建了一个以冗余资源为调节变量,工作形塑为中介变量的前摄型人格影响员工创新绩效的被调节的中介模型。以银行员工为调研样本,运用层次线性回归方法进行统计分析。研究结果显示：前摄型人格和工作形塑均显著正向的影响员工创新绩效,工作形塑在前摄型人格对员工创新绩效影响关系中起部分中介作用;冗余资源对前摄型人格与形塑之间关系起正向调节作用,而在前摄型人格与形塑之间关系的调节作用是非线性,倒U型的;冗余资源正向调节着工作形塑在前摄型人格与员工创新绩效之间的间接效应,即冗余资源较高时,前摄型人格通过工作形塑对员工创新绩效产生的间接作用更强。     

关于中国城市化进程中民工潮现象的思考

本文在分析民工潮现象表征和成因的基础上,指出：城市化的历史必然性与我国城乡二元社会经济结构相撞击是形成民工潮现象的根本原因;并从正负两方面效应阐述了民工潮对我国城乡社会经济发展的影响,尤其是正面影响;最后提出民工潮的疏导化解对策。     

生产性服务业的质与量对制造业的溢出效应研究—来自OECD国家的随机前沿方法的分析

本文用随机前沿生产函数方法对ＯＥＣＤ国家１９８９～２００８年间面板数据分析,得到生产性服务的质量因素可以显著解释无效率项,而数量因素则不能,且生产性服务对制造业产出增长的贡献度比科布—道格拉斯生产函数所估计的值高１２％ ～１３％。得出结论为：生产性服务对制造业的溢出效应由技术、知识密集度代表的质量因素和劳动占比代表的数量因素共同影响。故产业政策的制定需促进生产性服务质与量共同发展。     

新加坡中央公积金投资运营分析及对中国的启示

新加坡中央公积金制度是养老金个人账户制度中集中管理、集中投资的典型,但同时也不断放宽投资政策,允许其成员进行多元化的积极投资。本文通过梳理、分析新加坡中央公积金集中投资、积极投资的发展及其问题,总结出对中国养老金制度改革和养老基金管理有益的启示。     

关于农业剩余劳动力转移的几点认识

改革开放以来,农村劳动力呈现出从最初的就近转移到跨区域和梯度转移,这种大规模的人口流动过程对中国的经 济增长以及农村经济的繁荣曾经产生较大的影响,并孕育着新的契机。本文计算了农村剩余劳动力转移对经济增长的贡献, 并从正反两方面,论述了1991-2002年农村剩余劳动力转移对于农业乡镇企业以及经济增长的贡献。     

集体主义人力资源管理与员工积极、消极互惠：组织认同与关系认同的中介差异

积极互惠与消极互惠是互惠行为中概念相对的重要组成,文章从集体主义人力资源管理出发,比较其对两种互惠行为的影响,并以组织认同、关系认同作为中介变量研究其中介差异。研究结果显示,集体主义人力资源管理可以提升员工的积极互惠,降低员工的消极互惠,而积极互惠与消极互惠也并非负相关。此外,尽管组织认同、关系认同分别发挥了中介作用,但当整体考虑时,在集体主义人力资源管理与积极互惠间,由组织认同发挥中介作用,为部分中介;而在集体主义人力资源管理与消极互惠间,由关系认同发挥中介作用,为完全中介。说明同属互惠行为,积极互惠、消极互惠存在不同的前因机制;同属认同,组织认同、关系认同存在不同的影响机制。本研究对于集体主义下的管理实践,尤其是对组织内互惠行为、认同现象的整体性思考有重要意义。

Dynamic strategic groups: deriving spatial evolutionary paths

Recent theoretical developments in the domain of strategic groups, specifically those related to cognitive groups and strategic group identity, seem to suggest that strategic group membership is likely to be relatively stable over time and that firms in a strategic group co‐evolve. Yet appropriate data analytic approaches that use information about firms over time to identify stable strategic groups and their evolutionary paths have been lacking. To overcome such limitations, this research proposes a new clusterwise bilinear multidimensional scaling model that can simultaneously identify (1) the number of strategic groups, (2) the dimensions on which the strategic groups are based, and (3) the evolution of the strategy of these groups over time. Our discussion encompasses various alternative model specifications, together with model selection heuristics based on statistical information criteria. An illustration of the proposed methodology using data pertaining to strategic variables for a sample of public banks in the tristate area of New York, Ohio, and Pennsylvania across three time periods (1995, 1999, and 2003) identifies two underlying dimensions with five strategic groups that display very different evolutionary paths over time. Post hoc analysis shows pronounced differences in firm performance across the five derived strategic groups. This article concludes with a discussion of the implications of the findings, as well as potential future research directions. John Wiley & Sons, Ltd. Copyright © 2009 John Wiley & Sons, Ltd.
