偏心支撑钢框架是在支撑钢框架的基础上改进的一种新型抗侧力体系,该体系结合了中心支撑钢框架强度、刚度高和抗弯框架延性、耗能性能好的优点,是适用于高烈度地震区的一种有效的抗侧力结构体系。同时,由于多高层钢框架的广泛应用,其层数不同将会导致柱轴心压力的不同。本文通过应用ANASYS有限元程序对其在不同轴心压力下的受力性能进行分析。  相似文献

Nudging the amelioration of enterprise environmental performance is the micro-foundation for effectively enhancing resource utilization and realizing sustainable development. Based on the upper echelons theory, the characteristics and previous experiences of managers determine their strategic choices and then affect the behavior of enterprises at the whole social layer. Nevertheless, the literature concerning the effect of CEO green experience on enterprise environmental performance is void. To bridge this gap, this paper uses the data of China's A-share listed enterprises from 2010 to 2021 to empirically investigate the direct impact, influence mechanisms, and heterogeneities of CEO green experience on enterprise environmental performance. The study finds that CEO green experience can significantly promote the improvement of enterprise environmental performance. Based on the main effect, to exploring potential mechanisms behind the conclusion, we figure that environmental ethics commitment, environmental protection investment, and green technology innovation are the core mechanism approaches during the process of CEO green experience affects environmental performance. Heterogeneity analysis of CEO characteristics demonstrates that the green experience of female CEOs, older CEOs, and high educated CEOs both have a pronounced effect on ameliorating enterprise environmental performance. Furthermore, the positive effect of CEO green experience on environmental performance is more prominent in non-state-owned enterprises, heavily polluting industries, and regions with high environmental protection pressure. Besides providing an effective supplement for the research on managers and environmental performance, this paper also generates micro-empirical support for government departments to formulate and optimize environmental policies.  相似文献

We test a sample of 3,586 banks from 33 European countries to determine whether performances above or below a social aspiration level (median performance of peer banks) influence banks’ aggregate risk levels. Our results are consistent with the behavioural theory of the firm and prospect theory in that we find that bank performance below a bank’s social aspiration level is followed by increased aggregate risk, i.e. risk-taking behaviour in the subsequent year. Although under-performing banks tend to be risk-takers, large banks and banks with high aggregate risk levels tend to limit the increase in their aggregate risk levels.  相似文献

ABSTRACT

The success of small and medium-sized enterprises (SMEs) depends on dynamic capabilities, as it provides opportunities to remain competitive and perform well in the dynamic business environment. Although several studies show the significant positive impacts of dynamic capabilities on firm performance, our knowledge of the underlying mechanism through which IT capabilities affect the firm performance is not yet clear. Applying the dynamic capability view, this study investigates the intervening role of absorptive capacity and corporate entrepreneurship. The data of 417 respondents is collected from medium-sized manufacturing sector SMEs in Punjab, Pakistan. The research hypotheses have been analysed through the structural equation modelling method by using the Smart-PLS software. The research findings show that absorptive capacity and corporate entrepreneurship partially mediates the relationship between IT capabilities and firm performance. Furthermore, the sequential path of IT technical skills, absorptive capacity, corporate entrepreneurship, and firm performance is highly significant as compared to other paths.  相似文献

ABSTRACT

This study empirically analyzes the impact of childcare costs on the labor force participation (LFP) and childcare utilization of migrant and local mothers of preschool-age children in urban China, using data from the 2010 National Dynamic Monitoring Survey of Floating Populations. The estimates show that childcare costs have a strong negative effect on the LFP and childcare utilization of migrant and local mothers. Compared to local mothers, the LFP and childcare utilization rate of migrant mothers are, respectively, more and less sensitive to changes in childcare costs. The analysis indicates that the LFP and childcare choices of migrant mothers are more constrained by the lack of access to affordable childcare than are local mothers in China.  相似文献

We examine the impact of CEO power on reading difficulty of corporate annual reports. We find that CEO power is positively related to reading difficulty, implying that annual reports of corporations with powerful CEOs are difficult to read and understand. More importantly, we find that the relation between CEO power and reading difficulty is moderated by earnings performance or corporate governance. Additional findings suggest that this relation becomes stronger for firms with lower financial reporting quality or for CEOs with shorter tenure. Our study not only joins the debate on the consequences of powerful CEOs but also uncovers several factors that moderate the relation between CEO power and annual report reading difficulty.  相似文献

We investigate the disclosure of non-IFRS performance measures by 400 companies from eight countries using IFRS Standards (Australia, France, Germany, Hong Kong, Italy, Singapore, Sweden and the United Kingdom) in the years 2005, 2008, 2011 and 2013 (1595 company-years). The incidence of disclosure is higher in UK and France but lower in Hong Kong, Germany and Singapore. Exclusions relating to impairment, tax, and mergers and acquisitions are frequent. Firms making non-IFRS disclosures are more likely to be larger, have higher leverage, and exhibit greater volatility in their reported income. Additional tests show national reporting traditions and practices affect non-IFRS disclosures.  相似文献
