从投资者结构角度研究企业层面工业智能化的驱动力,用委托代理理论分析股权结构对企业智能化投资的影响。以中国制造业上市公司为研究样本,实证检验股权结构对企业智能化投资的关系。研究结果表明,从股权集中角度看,一定的股权制衡很有必要,一股独大不利于企业智能化投资;从企业性质看,公有企业更愿意进行智能化投资,个人私有的第一大股东不太愿意进行智能化投资;从激励角度看,高管薪酬与智能化投资之间的关系不明确,说明目前的薪酬激励制度不够合理;从地区文化角度看,越是发达的地区企业越容易接受智能化投资。  相似文献

This study examined the structural relationships among three different dimensions of workplace stressors (customer-related stressor, CRS; work environment-related stressor, WERS; job-related stressor, JRS), negative affectivity (NA), emotional exhaustion (EE), and the negative effect of that strain on customer orientation (CO) in the context of the emotional labor (EL) of frontline employees in the hotel industry. Data were collected from self-administrated questionnaires distributed among frontline employees in room and F&B divisions in Korean deluxe tourist hotels, where EL is intense. The results of the structural equation analysis indicated a positive association between all three workplace stressors and NA and between NA and EE. There was also a relationship in the opposite direction with EE and CO, as hypothesized. The moderating effect of organizational level on the workplace stressors–NA relationships was also confirmed. In addition, in an alternative model, we found that NA partially mediates the relationship between JRS and EE; whereas, NA fully mediates the relationships between CRS/WERS and EE. Practical implications are discussed in detail and limitations of the study and future research directions are also suggested.  相似文献

During the recent and ongoing economic turmoil, countless businesses have been facing financial distress and many have filed for bankruptcy. This issue is especially critical for the restaurant industry due to restaurants’ sensitivity to economic fluctuations. Therefore, the purpose of this study is to examine the financial distress issue in the U.S. restaurant industry. In particular, the study examines a moderating effect of capital intensity on the relationship between a firm's leverage and degree of financial distress. The dataset includes publicly traded U.S. restaurant firms during the period 1990–2008. The study measures the degree of financial distress by modified Z-scores, and findings suggest a positive moderating effect of capital intensity on the relationship between leverage and financial distress.  相似文献

国际资本引入对商业银行效率影响的实证研究   总被引:1,自引:0,他引:1  
张弛 《技术经济》2007,26(5):67-72
引入国际战略投资者是国内商业银行提高自身竞争力的有效途径之一。本文首先对引入国际资本后可能产生的各项效应进行分析,继而运用数据包络分析(DEA)方法对引入国际战略投资者前后各商业银行的效率进行了测度,说明其变化情况;并以可能造成效率变化的因素为自变量,银行效率为因变量建立线形回归模型,发现资本充足率高低对银行效率并无直接影响,但产权结构与银行效率显著相关。最后给出相关政策建议。  相似文献

More diverse, perennial cropping systems often have better natural mechanisms for keeping pests at bay. But while scientists emphasise the broad benefits of conservation in terms of effective ecosystem functioning, farmers are more interested in biodiversity for the provision of food or of services such as shade or windbreaks. Because of their limited knowledge of the role of biodiversity in plant protection, farmers sometimes unconsciously disturb natural regulatory mechanisms. Some citrus farmers in Vietnam introduced sapodilla as an intercrop to diversify their source of income, and because this fruit tree requires little care. However, this apparently worthwhile attempt to combine two valuable crops has misfired. The ecological conditions that traditionally sustained natural pest control in citrus have been disturbed, thus trapping farmers in the pesticide treadmill. The weaver ant Oecophylla smaragdina stopped protecting citrus from stinkbugs and leaf-feeding caterpillars after facing competition from the black ant Dolichoderus thoracicus, which favours sapodilla trees as a nesting habitat. To avoid similar scenarios in the future, methods for linking scientific research on ecosystem functions with farmers' own knowledge, experience and priorities are presented. Examples are given of ways in which farmers in perennial cropping systems learn, and how scientists can facilitate this learning process.  相似文献

This study compared intergenerational earnings mobility in Singapore and the United States by replicating the sample criteria in the Singapore National Youth Survey on the U.S. Panel Study of Income Dynamics. The mean estimated earnings elasticities are almost identical: 0.26 in Singapore and 0.28 in the United States. Transformed to 0.44 and 0.47 respectively to reflect permanent status, mobility in the two countries is moderately low compared internationally. The finding of similar mobility is not surprising given that the two countries have similar economic realities, welfare systems, education regimes, and labor structures. Policy makers face the daunting challenge of overcoming immobility and inequality while maintaining global competitiveness.  相似文献

Numerous studies have identified constructs such as commitment and brand familiarity as moderators of negativity effects. However, boundary conditions for this moderation have yet to be identified within a retailing context. This study tries to rectify this gap in the literature. This study finds that three factors (commitment, consumer–company identification, and consumer sensitivity to corporate social performance) moderate attitude change toward a retailer following exposure to moderately negative (vs. positive) publicity. However, given extremely negative information, the buffering effects of the moderating factors disappear, and attitude changes are significant for all consumers. © 2009 Wiley Periodicals, Inc.  相似文献

In this paper, we investigate the optimal form of reinsurance from the perspective of an insurer when he decides to cede part of the loss to two reinsurers, where the first reinsurer calculates the premium by expected value principle while the premium principle adopted by the second reinsurer satisfies three axioms: distribution invariance, risk loading, and preserving stop-loss order. In order to exclude the moral hazard, a typical reinsurance treaty assumes that both the insurer and reinsurers are obligated to pay more for the larger loss. Under the criterion of minimizing value at risk (VaR) or conditional value at risk (CVaR) of the insurer's total risk exposure, we show that an optimal reinsurance policy is to cede two adjacent layers, where the upper layer is distributed to the first reinsurer. To further illustrate the applicability of our results, we derive explicitly the optimal layer reinsurance by assuming a generalized Wang's premium principle to the second reinsurer.  相似文献
