This study applies the theory of self-concordance and adopts the multi-level analysis approach to examine the mediating effect of employee self-concordance, a core component of intrinsic motivation, on the relationship between social-contextual factors and creativity using hotel industry data obtained from Mainland China. The hierarchical linear modeling (HLM) results from a multisource sample reveal that the three social-contextual variables (i.e., organizational modernity, empowering leadership, and coworkers support and helping) were associated with employee self-concordance, which in turn was associated with employee creativity. Moreover, employee self-concordance fully mediated the three social-contextual variables and creativity. This study shows that organization environment plays a significant role in predicting employee creativity. The implications of the findings for future research and their practical applications in the hotel industry are discussed.  相似文献

The diffusion and adoption of modern information technology provide new chance for China to close urban-rural income gap. This paper uses China's provincial panel data from 2002 to 2013 to investigate the effect of computer penetration on rural residents' income. A public program aiming to connect every village with broadband Internet and other rural facilities provides plausibly exogenous variation in rural residents' availability and adoption of the broadband Internet, which is used to explore the instrument variable for rural computer penetration. The results show that rural computer penetration tends to increase rural residents' income over time, but the average effect remains limited. The dynamic panel threshold effects model, which allows for both the threshold variable and other covariates to be endogenous, is further used to explore the constraints of the income-increase effect of rural computer penetration. It shows that the effect is at least doubled over the average effect estimated from instrument variables method, once the digital divide causes are removed. Our findings have important implications for the government to increase rural residents' income and reduce urban-rural income gap by encouraging rural computer usage and removing the digital divide.  相似文献

This paper explores the determinants of the individual's decision to perform cross-border e-commerce (CBeC). The European Union (EU) is especially interested in the promotion of CBeC because it is an important tool in its strategy to achieve the Digital Single Market in Europe. In this paper official data is used from a representative survey of 16,209 individuals on ICT usage by households and individuals that was carried out in Spain by the National Institute of Statistics (INE) for the year 2016. Using a standard neoclassical utility maximization framework, and logistic regression techniques, the results show that being a male is positively related to the probability of practicing CBeC. Education is positively and significantly related to the probability of being involved in CBeC with EU countries. Computer and Internet Skills are significant and positive factors in explaining CBeC (either with EU countries or with the rest of the world). The variable “how often the consumer sees other customer reviews before buying online”, has a positive effect. Foreign nationality also increases the likelihood of using CBeC. To promote CBeC in Spain measures towards developing digital skills, Internet trust and use of online information reviews of goods and services are discussed.  相似文献

建构主义理论认为:知识是个体主动建构的,是个体与他人通过磋商并达成一致的构建过程。在这种理论的指导下,学习观和教学观都发生了深刻的变化,这种理念强调以学习者为中心,注重互动、合作的学习方式,尊重个人意见和学习者已有的知识经验;同时教师的作用转变为设置适当的学习情境,鼓励学生反省与思考,帮助学生进行知识的意义建构。本文以第二版的《新视野大学英语》第二册第七单元TextA的课文为例,以建构主义学习理论为指导,在把握课文篇章意义和结构的基础上,遵循认知规律,设计不同层次的学习活动,让学习者循序渐进地完成这些任务,在头脑中构建词汇的意义和应用,最终培养同学的创造性,提高同学自主学习的积极性。  相似文献

This paper examines the interrelationship between two hierarchically structured functional capabilities pertinent in the organizational procurement process, and the impact of these capabilities on procurement process performance. These functional capabilities operate at different levels in an organization's procurement process. We draw upon resource- and knowledge-based views of the firm to theorize that in this hierarchy of information technology-enabled procurement capabilities, the higher-level capability – procurement integration competence – enables firms to develop and deploy a lower-level capability – digital procurement competence. Further, we theorize that the lower-level capability impacts procurement process performance directly and completely mediates the relationship between higher-level capability and performance. Thus, although performance is impacted directly only by the lower-level capability, the higher-level capability facilitates the development and use of the lower-level capability. Our research model is tested using survey data from a large sample of 412 manufacturing firms. The results provide strong support for the proposed research model. In particular, we find that as hypothesized, the impact of procurement integration competence on performance is completely mediated by digital procurement competence. Our results suggest that when examined at the procurement process level, the impact of higher-level capabilities may be manifested completely through the lower-level capabilities. Theoretical and practical implications of the research are discussed.  相似文献

Despite extensive literature on green hotel management and sustainability, scant attention has been given on the role of managers to solve environmental related issues. This study's aim is to assess the effects of managers' green knowledge and green transformational leadership on firms' environmental performance with the mediating effect of green creativity. The study analyzes the perceptions of 363 employees in different managerial positions of the hotel industry employing Partial Last Square Structural Equation Modeling. The findings of the study show a positive effect of green knowledge and green transformational leadership on green creativity and green transformational leadership on environmental performance. Furthermore, green creativity is also found to have significant mediating effect between green knowledge and environmental performance, and green transformational leadership and environmental performance relations. The main implication of the current research is that managers' green concerns might help the stakeholders in the hotel industry to respond through appropriate green initiatives for their organizations. Further suggestions for literature and practice are discussed.  相似文献

Scholars and policymakers interested in the growth and prosperity of regions have long recognized that talent and knowledge are fundamental. Yet the question is what types of talent are needed in a growing twenty‐first‐century economy: human capital, creativity and innovation, or entrepreneurship? The latter we define broadly to include any type of risk taking, and not only radical innovation. The literature does not clearly point to one factor as being the most essential. This study assesses this question separately for rural and urban United States (US) counties. We find that human capital––measured by educational attainment––is considerably more conducive to employment growth than the share of creative occupations. Likewise, the share of small and medium businesses is also very conducive to local growth, although this does not apply to the self‐employment share. Rural and urban areas experience similar patterns, although the magnitude thereof tends to be larger for urban counties, whereas high‐technology employment share has had a positive effect in rural areas. Policy conclusions suggest that enhancing small business development and increasing educational attainment are the two strategies that are most likely to succeed.  相似文献

Our planet is gradually moving towards an urbanized world. Modern urban agglomerations tend to turn nowadays into advanced information hubs supporting a smart management of dynamic urban systems. The currently popular notion of ‘smart cities’ aims to provide a new perspective for sustainable and high-performance strategies of city stakeholders in our ‘urban century’. In this context, digital information technology provides a new tool for efficient and effective management and planning of urban space, inter alia in the field of transportation, environment, public facilities or advanced service provision to citizens. This paper aims to offer, first, a concise overview of the emerging opportunities of information and communication technology (ICT) for smart urban policy; digital technology in particular, appears to provide novel pathways for modern planning strategies in smart cities. Against this background, the paper sketches out the complex force field of global urbanisation phenomena and highlights the data and information needs for strategic planning of cities (using inter alia as a framework the so-called ‘urban piazza’ strategy framework). Secondly, various new decision support tools that are currently emerging and that offer a new promising scope for handling complex urban management issues (for instance, on accessibility, congestion, safety or sustainability) are briefly presented. And finally, the potential of such digital data systems for urban management and policy is concisely illustrated by means of some recent applications in the area of smartphone data systems. The paper concludes with a discussion of the challenges ahead for urban policy, inter alia by paying attention to institutional and governance aspects of ‘big digital data’ management in urban systems.  相似文献
