装配式建筑是一种比较新颖的建设模式,提前预制组件,然后运到工地组装完成工程项目。整个过程方便、高速、环保,在很大程度上减少了施工过程中对资金、时间和人力的损耗。我国对装配式建筑给予了高度重视并加强了推行力度,使装配式建筑技术发展极为迅速。由于质量管理不到位,引发的装配式建筑技术没有得到较好的应用,所以需要完善和优化质量管理,以保证工程质量和施工的安全性。 相似文献

This study aims to clarify the relationship between environmental performance and financial performance by introducing clean technology as the moderating variable. We contest two major theories, natural resource-based view theory and neoclassical theory, to reveal a comprehensive understanding of environmental performance's impact on financial performance. The hypotheses are tested on 111 global oil and gas companies using dynamic panel generalized method of moments (GMM). Our analysis reveals three key findings. First, lower environmental performance leads to lower financial performance confirming the natural resource-based view theory. Second, clean technology has no significant effect on financial performance, arguing the marginal abatement cost. Finally, our results report that clean technology has no impact on increasing financial performance during high waste spills or high emissions. Theoretical and practical implications resulting from the adoption of clean technology to moderate the environmental impact on financial performance are also discussed. 相似文献

In this article, we investigate the financial implication of sustainable environmental practices on UK small and medium‐sized enterprises (SMEs)–traded firms. Existing literature indicates that there is a direct relationship between sustainable environmental practices and financial performance. However, studies looking at this relationship have focused mainly on large firms with little attention paid to SMEs. Further, those looking at environmental and financial performance relationships have often used a single measure of performance in their studies. This study bridges these research gaps by focusing on listed SMEs in the United Kingdom using multiple measures of sustainable environmental policy indices on a panel of 201 SMEs on the Alternative Investment Market from 2011 to 2016. Evidence from our panel data analysis suggests significant and a nonlinear (concave) relationship between sustainable environmental practices and firms' financial performance. Specifically, energy efficiency practices, greenhouse gases, material, and resource efficiency revealed an inverted U‐shaped relationship with financial performance. The results will offer guidance to management in terms of allocating resources to sustainable environmental practices investment. 相似文献

The purpose of this study is to investigate the impact of board sustainability committees on environmental and social performance and to examine the mediating effect of corporate social responsibility (CSR) strategy on the relationship between the presence of board sustainability committees and corporate sustainability performance. Using data of U.K. listed firms for the period of 2009–2016, the study employs panel regression analysis and bootstrapping techniques to test study hypotheses. The results suggest that the presence of a sustainability committee improves the effectiveness of CSR strategies. The results also indicate that firms with effective CSR strategies exhibit better environmental and social performance. Further, the empirical results show that the effectiveness of CSR strategy explains the positive relationship between board sustainability committees and corporate environmental and social performance, thus supporting the theoretical framework of the study. The findings of the study shed new light on this research direction and could be of interest to board members, managers, practitioners, investors, policy makers, and regulators that plan to promote sustainability practices and strategies needed for sustainable development. 相似文献
