The present study examines the curvilinear relationships between LMX/TMX and team members' turnover intention simultaneously. That is, members with high LMX, TMX, or both are more likely to have turnover intention. Hypotheses were tested with a sample of 452 nurses, and we adopted the response surface methodology and polynomial regression to test our theoretical model. The hierarchical regression analysis showed that TMX has a U‐shaped relationship with turnover intention but not with LMX. In addition, the results indicate that both the congruence and incongruence of LMX and TMX result in higher turnover intention, but moderate levels of LMX and TMX have the lowest turnover intention. Strengths, limitations, practical implications, and directions for future research are discussed. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.  相似文献

Corporate venturing (CV) in which established firms invest in new entrepreneurial businesses involves identifying opportunities and creating new combinations of resources to seize opportunities. Moving beyond literature that has focused predominantly on the consequences of CV, we adopt a resource‐based view to examine how knowledge‐based and organizational‐slack resources relate to the level of firm CV. The implications of the findings for future research are discussed. Copyright © 2011 ASAC. Published by John Wiley & Sons, Ltd.  相似文献

This study examines the relationship between real effective exchange rates (REERs) and the consumer price index (CPI) in China, utilizing a bootstrap Granger full-sample causality test and a sub-sample rolling-window estimation. Considering structural changes, we assess the stability of the parameters and find that both the short-run and long-run relationships between the two estimated variables are unstable. This result suggests that full-sample causality tests cannot be relied upon. We instead employ a time-varying (bootstrap) rolling-window approach to revisit the dynamic causal relationship, and we find that the CPI is affected by the REER for several sub-samples due to the role of exchange rate pass-through (ERPT) under the managed floating exchange rate regime in China. These findings provide further proof of the impact of stable exchange rates on the maintenance of relatively steady price levels especially during the economic crisis and economic reform in China. The policy implication of these findings is that maintaining exchange rate stability is beneficial for controlling inflation during the economic crisis and economic reform.  相似文献

浙江民营经济增长要素的实证分析   总被引:5,自引:0,他引:5  
本文从要素投入角度,对浙江民营经济的高速增长进行实证研究.通过对历史数据的计量分析,揭示了制度改进与技术进步是推动浙江民营经济增长的首要因素,资本积累的作用其次,而劳动投入贡献最少.从走势看,近几年浙江民营经济总体呈粗放型增长态势,主要表现为以高强度的资金投入来推动经济的高增加.随着体制优势的不断淡化,以及宏观调控对投资的影响,要继续保持浙江民营经济的快速发展,当务之急,是大力加快技术创新,转变增长方式.  相似文献

With the rapid development of apparel mobile commerce in the United States, more companies view mobile commerce as a new source of competitive advantage. Despite the importance of apparel mobile website quality and its effect on consumer satisfaction and future purchase stimulus, extant research has paid little attention to these topics. This study proposes a website quality–consumer satisfaction–purchase intention research model based on the self-regulatory process theory. Six dimensions of apparel mobile website quality—website visual appeal, apparel visual appeal, brand trust, website information quality, website response time, and website security—were investigated. In all, 293 eligible responses were collected via an online survey. Multiple regression analysis was utilized to test the proposed relationships. Results reveal that website information quality, website visual appeal, apparel visual appeal, and website security positively affect consumer satisfaction toward apparel mobile commerce websites, while website response time and brand trust show insignificant impacts on consumer satisfaction. With higher satisfaction on an apparel mobile commerce website, consumers are more likely to purchase apparel through the website.  相似文献

The recent proliferation of computer networks has stimulated the emergence of thousands of online communities. Facebook, which has grown to 175-million users in five years and recently surpassed megasite MySpace to become the world's largest social networking site, is a classic example. As the importance of online communities continues to grow, a good understanding of their success factors for building and sustaining a community becomes crucial.

In this article, we apply social capital theories to examine the interactions among individuals and trust building at the initial development of an online community. Specifically, we postulate that offline social capital can be transplanted into an online community (small or large) to foster the development of trust and social norms that make a community thrive. We conduct two experimental studies: one in the context of real-world, small-scale online communities, and the other in the context of computer-simulated large-scale online communities. Results from these studies provide strong support for our proposition. We interpret these results and discuss their implications and contributions to theory and practice.  相似文献

Although a general association between the role of international assignees and knowledge transfer has been noted in the international human resource literature, very little is known on how subsidiary knowledge flow strategies influence the purpose of expatriate assignments. Building specifically on Gupta and Govindarajan’s typology of subsidiary knowledge flow strategies and Hocking’s expatriate assignment purpose, we examine the link between subsidiary knowledge flow and the purpose of expatriate assignments using a mixed method approach. Combining survey data and qualitative interviews from 156 subsidiaries in the service and manufacturing sector in Malaysia and Singapore, we find that subsidiaries with divergent strategic roles have different knowledge flow strategies, thus leading to different purposes of expatriate assignments.  相似文献
