Environmental sustainability is a growing global concern. Environmental management systems (EMS) could be an effective strategic tool to help firms deal with their sustainable development. However, whether EMS certification pays off financially and how it takes effect can be debated. Thus far, these questions remain largely under‐researched. In particular, the effects of EMS certification on financial performance are inconclusive, and the reasons explaining the effects are underdeveloped. This study aims to enrich the current research by exploring the mediating and moderating roles from the perspective of cost‐efficiency trade‐offs to reveal how EMS certification affects financial performance. Applying a PROCESS procedure analysis and causal mediation analysis to a sample of 1,751 Chinese listed manufacturing firms from 2008 to 2016, this study shows that the effect of EMS certification on firms' financial performance is insignificant because their operating costs burden increases while their marketing efficiency and managerial efficiency improve. For the first time, this study demonstrates the moderating role of industry peer learning, as the mediating effects decrease with the growth of industry peer learning. 相似文献

大数据时代,传统的以“信息收集”规制为着力点的个人信息保护出现适法性困境,以“知情同意”为框架的机理失灵,个人信息的利用对象从直接个人信息逐渐向间接个人信息过渡,其财产价值凸显,新型个人信息财产权呼之欲出。立法应顺应数字经济的发展,构建合理新型个人信息体系。具体而言:纵向层面,以“宽进+删除权”为具体保护策略;横向层面,在信息主体和信息产业者之间合理配置权利,即信息主体享有个人信息权和个人信息财产权,信息产业者享有信息资产权。 相似文献

We examine the relationship between environmental regulation and spatial development in China. Exploiting changes in national pollution standards for three industries, ammonia, paper and cement, we measure the impact of environmental regulation on industry productivity. Our results suggest that national pollution standards do not affect industry productivity, but they reallocate productivity spatially. We show that regulated industries located in developing cities increase their productivity compared to similar industries in other cities. This means that environmental regulation affects the spatial distribution of technology in China and might influence long‐term spatial development by reducing geographical disparities. 相似文献

在消费者具有环保意识的背景下,分析有无政府补贴时制造商环保努力对各节点企业价格、需求、利润等决策的影响,并进一步探讨补贴在各类最优策略中的作用。研究表明:环保努力能提高两类产品销售价格、扩大新产品需求,但对再制造品需求无影响;存在最优环保努力水平,使无政府补贴下制造商及系统整体利润最大;一定范围内补贴能遏制环保努力导致的再制造品销售价格上升,但对新产品价格无影响,且对零售商来说高补贴未必能带来高收益;消费者环保意识和制造商环保努力可以通过政府补贴影响产品需求和企业收益。 相似文献

This paper examines the impact of cross-country variation in shareholders' and debt holders' rights on post-IPO performance and survival of newly listed stocks across the globe. Using a sample of 10,490 initial public offerings (IPOs) in 40 countries between 2000 and 2013, we find that post-IPO performance and survival is better in countries with stronger shareholder protection, but the impact of creditor protection is negative i.e. stronger creditor protection leads to poor post-IPO performance and survival. This effect is driven by rules requiring creditors’ consent for company reorganization and the mandatory replacement of incumbent managers. Reputable IPO advisors exacerbate the positive impact of shareholder rights and the negative impact of creditor rights. 相似文献

以2015~2018年A股上市公司为研究对象,考察企业精准扶贫行为动因与方式选择及所引起的市场反应。结果发现:国有企业和政治关联民营企业精准扶贫更积极,但两者精准扶贫方式存在差异,国有企业更倾向整合型精准扶贫,政治关联民营企业则倾向慈善型精准扶贫。进一步,企业参与精准扶贫产生了积极市场反应;相较国有企业,民营企业精准扶贫产生的市场反应更积极,尤其体现在政治关联民营企业中。同时,扶贫方式及扶贫持续性对精准扶贫信息披露的市场反应有影响。 相似文献

This is the first paper to show that participation in an international environmental agreement has some effectiveness. Our identification strategy consists of applying difference-in-differences techniques in a panel data framework to various levels of data aggregation. We find that ratification of the Rotterdam Convention (RC) and the Stockholm Convention (SC) leads to a reduction in trade of hazardous substances from OECD to non-OECD countries. In particular, we find that when the exporter ratifies the RC, there is a reduction in the import of hazardous chemicals of about 7 percent. In the case of the SC, the results show significant reductions of around 16 percent in trade shipments of persistent organic pollutants. This reduction is more than double the effect found for the RC, which was expected due to a more restricted obligation imposed by the SC convention. 相似文献

Based on the logic of “trust‐behavior,” we examined the relationship between interfirm cognitive trust, emotional trust, and firms' cooperation on environmental innovation, as well as the moderating role of environmental hostility on the relationship between two dimensions of interfirm trust and cooperation on environmental innovation. Data for the study were collected from 216 firms in China. The results indicated that both interfirm cognitive trust and emotional trust were positively correlated to firms' cooperation on environmental innovation, and the effect of emotional trust on firms' cooperation on environmental innovation was negatively moderated by environmental hostility. Finally, the results were discussed and future directions put forward. 相似文献

In this study, we develop a better understanding of the mechanisms by which corporate environmental ethics influences performance through the adoption of substantive actions. The empirical results of a moderated mediating analysis show that firms with higher environmental ethics are more likely to implement green marketing programs, consisting of the green production, pricing, distribution, and promotion programs and then improve firm performance. It is also observed that closure mechanism negatively moderates the mediation effect of green marketing programs because it leads to low trust and unwillingness to internal cooperation. These findings indicate that the value of corporate environmental ethics could not be determined in a vacuum, both strategy and people do matter when pursuing environmentally driven performance. 相似文献

Railways made a large contribution to the expansion of Victoria's economy, and in the process enabled and drove environmental change. This article focuses on one industry, forestry. It first examines railway demand for timber in construction and maintenance, particularly for sleepers. This demand caused tensions – a bitter dispute in the 1890s between the Railways Department and the Conservator of Forests, George Perrin, over timber cut on state land led to uneasy co-existence after the turn of the century. Railways not only required timber but also carried commercial quantities in bulk, providing forest industries with access to profitable markets – in particular firewood, the significance of which has been underappreciated previously. Forest products contributed substantially to railway revenue, representing a more stable source of income than other major categories of freight such as wheat, wool, and coal. 相似文献
