This research investigated how and under what conditions thriving at work affects career attitudes and behaviors. Using an experimental design (n = 174), Study 1 found that the effects of thriving on career satisfaction, career commitment, and career engagement were mediated by career resilience. The positive effect of thriving on career resilience and the resilience‐mediated effects of thriving on career satisfaction, commitment, and engagement were stronger when achievement orientation was higher. Study 2 verified these findings with a survey of another sample of 296 employees. These studies offer important insights for human resource managers and career consultants or practitioners regarding what may enhance employees' career outcomes. Our findings imply that thriving‐enabling practices might be beneficial among highly achievement‐oriented employees.  相似文献

Vertical specialization (VS) is quantified by the VS share, which measures the average import content per dollar of exports. A characteristic of China’s export trade is its strong dependence on assembly and processing activities. To take proper account of this, China’s VS shares should explicitly distinguish processing export production from other production. We estimate China’s annual VS shares from 2000 to 2012—the latest year for which a special input–output table is available that makes such an explicit distinction. We find that VS shares increased from 2000 to 2004 and subsequently started to decrease. To explore why it has declined, we introduce a new structural decomposition approach. We find that the decrease of the VS share appears to have been driven mainly by the substitution of imported intermediates by domestic products. This occurred in particular in the production of exports, which implies an upgrading of China’s position in global value chains.  相似文献

The subject of design and technology was introduced to the curriculum for high schools in China 10 years ago. However, the teaching and learning of this subject have become difficult for both teachers and students because there is a lack of qualified teachers with design background to deliver this subject in a way to stimulate the learning interests of the students. This paper presents a research that is aimed at improving this situation by integrating the teaching and learning of design and technology within a computational environment as part of social networks sites. The purpose is to enable the collaboration among the students and interaction between teachers and students. In this research, a series of investigations were conducted, by following through several taught subjects in design and technology in prominent high schools in China. Based on these investigations, a theoretical framework for web-based design learning and teaching system in the style of social networking is developed, implemented and tested, emphasizing three features of design: innovation, collaboration, and interaction. This framework has been tested among high school students and teachers in a high school in Nanjing. It identified and validated necessary techniques and design features required to make an education-related social networking site effective and affective for the students and teachers. The results of this research indicated that social networking sites have significantly positive values in design education, especially for the collaboration and interaction on the subject of design and technology.  相似文献

This paper investigates returns to women’s education by applying an optimal IV selection approach, post-Lasso IV estimation, which improves the first-stage predictive relationship between an endogenous regressor and instruments. Using the 2010 American Community Survey, we find that an extra year of education increases married women’s own income by $4,480 and spouse income by $8,822. Our findings indicate that 53% of the increase in women’s consumption by education is attributed to the marriage market, and thus, we conclude that the marriage market is the primary channel through which education improves women’s well-being. The results demonstrate the advantages of the post-Lasso approach: The resulting two-stage least squares estimator maintains efficiency without increasing finite sample bias and is less subject to the inconsistency problem when some instruments are invalid; This differs from the results using the instrument of birth quarters only, which is mostly applied in studies on returns to education.  相似文献

Previous research has shown that virtuous leader behavior in the form of benevolent leadership has considerable impact on employee creativity. However, little is known as to how and under what conditions these constructs are linked. In the current research, we proposed and tested a moderated mediation model positing leader–member exchange (LMX) as a mediator, and employee power-distance orientation as a moderator of this relationship. Two studies were conducted to test our hypothesized model. In Study 1, repeated measured data collected from 284 Chinese employees in an information technology company demonstrated that benevolent leadership had a lagged effect on LMX. In Study 2, analyses of multisource and lagged data from 391 Chinese employees in 42 research and development teams, and their direct supervisors indicated that benevolent leadership was positively related to supervisor-rated employee creativity via LMX. In addition, the relationship between benevolent leadership and LMX was stronger for employees high in power-distance orientation. Theoretical implications of benevolent leadership’s research and practical contributions concerning promoting creativity in organizations where benevolent leaders prevail are also discussed.  相似文献

We test whether bank competition affects firms’ leverage adjustment speeds. Using Chinese data where bank concentration varies across both years and provinces, we find that underlevered firms move to their target leverage faster when bank competition is high. Tests surrounding an exogenous shock to bank competition lead to the same conclusion. We also find that small firms and nonstate‐owned firms exhibit faster leverage adjustments when bank competition is high, which is consistent with the conjecture that bank risk taking increases with competition.  相似文献

This paper examines whether politically connected firms use related party transactions as a tunneling mechanism in Indonesia. We further investigate whether the presence of tunneling compels managers to manage earnings to conceal such expropriation of resources. Our study is motivated by conflicting evidence in the extant literature about the role of political connections and related party transactions. Using data from Indonesia, we document that politically connected firms use related party loans to tunnel resources, and that this effect is more pronounced for firms with government connections. We further document that politically connected firms manage earnings to conceal their tunneling activities. By documenting the role of related party transactions as a specific channel through which connected firms expropriate resources, we enrich the political connection and related party transactions literature.  相似文献

碳交易是推动制造业绿色发展,实现“双碳”目标的重要市场化工具,交易价格和市场规模能够反映碳交易实施状况,是影响制造业绿色全要素生产率的重要因素。从碳交易价格和市场规模切入,基于2008—2020年中国内地30个省份面板数据,构建连续型双重差分模型评估碳交易对制造业绿色全要素生产率的作用效果,并考察异质性技术创新模式的传导路径。结果表明,提高碳交易价格和扩大市场规模均能显著提升制造业绿色全要素生产率。机制检验表明,碳交易价格和市场规模能够推动自主创新、减少技术改造投入,进而影响制造业绿色全要素生产率,而技术引进并非有效路径。进一步研究发现,自主创新对技术改造存在挤出效应。研究结论对完善碳交易制度顶层设计、精准制定技术创新配套政策具有重要启示意义。  相似文献

本文将银行内部创新因素和外部创新环境引入银行风险承担研究框架,从理论和实证两个方面分析创新对银行风险承担的影响。研究结果发现,创新与银行风险承担之间呈现"U型"的关系,适度创新能够弱化银行风险承担,过度创新会加剧银行风险承担。进一步研究发现,内部创新对非五大行具有当期和滞后的双重影响,而对五大行仅具有当期效应。外部创新对五大行具有当期和滞后的双重影响,而对非五大行的当期影响不显著。企业还款能力、银行贷款质量和创新资产规模是创新影响银行风险承担的重要中介机制。此外,五大行对创新的敏感性小于非五大行,五大行可接受的创新区间大于非五大行。  相似文献
