Environmental management systems and technological environmental innovations: Exploring the causal relationship 总被引：1，自引：0，他引：1
Within the discussion of voluntary proactive approaches to environmental protection, former micro-econometric studies analyze the causal effect of the adoption of environmental management systems (EMS) on technological environmental innovations and find some positive impacts. Based on empirical studies which consider the effect of general innovativeness on the adoption of voluntary environmental programs (VEP) as well as based on insights from the resource-based view of the firm, we contrarily hypothesize in this paper that EMS could also reversely be affected by environmental product or process innovations. This hypothesis is empirically examined with a unique firm-level data set from the German manufacturing sector. Our econometric analyses with uni- and multivariate probit models imply a significantly positive effect of environmental process innovations on certified EMS. According to this, the causal relationship between EMS and technological environmental innovations is obviously not clear. 相似文献

On the relationship between environmental management, environmental innovation and patenting: Evidence from German manufacturing firms 总被引：1，自引：0，他引：1
This paper analyses empirically the relationship between environmental innovations, environmental management and patenting. In particular it tests a number of propositions on how environmental management systems and the interaction with environmentally more or less concerned stakeholders are associated with the probability of firms to pursue innovation in general (measured as patenting behaviour) and specifically environmental innovation (measured based on firm self-assessment and through patent data). In applying a negative binomial as well as binary discrete choice models the relationship is studied using data on German manufacturing firms. As a novel and important insight, the study finds that environmental innovation can be meaningfully identified using patent data and that environmental innovation defined this way is less ubiquitous than self-reported environmental innovation. It also reveals that the implementation level of environmental management systems has a positive effect exclusively on environmental process innovation, whereas it is negatively associated with the level of a firms’ general patenting activities. For environmental product innovation and patented environmental innovations a positive relationship with environmentally concerned and a negative link with environmentally neutral stakeholders is found. 相似文献

随着环境事业的不断发展,环境教育立法的重要性日益突显。我国目前环境教育滞后于环境保护事业发展需要,环境教育立法亟待完善。日本在《环境教育推进法》等相关立法中,为唤起国民对环保活动价值正当性的自觉、认同与实践的意欲,在立法中确立了关于"社会参与"的激励原则,对构建可持续发展社会有着深远的影响与意义,值得我国在今后的环境教育立法中加以借鉴参考。 相似文献

This paper addresses the question of how firms accomplish the strategic task of adapting their entire set of IORs (interorganizational relationships) to changing environmental conditions. To study this, we move beyond the focus on collaboration with individual partners (the dyadic perspective) that has been the dominant emphasis in the literature until now. Instead, we view the firms’ portfolios through the lens of the different modes of IOR engaged in (licensing agreements, non-equity alliances, venture capital investments, minority investments, joint ventures, and mergers & and acquisitions). We study the role of environmental change within the high-tech setting of the bio-pharmaceutical industry and distinguish between industry technological change and firm-specific technological change. In doing so, we rely on prospect theory to theorize how firms’ perceptions of environmental change in terms of a looming loss or a potential gain affect their risk-bearing, how this leads them to adjust their IOR portfolio diversity, and how these adjustments get implemented at the mode level. Whereas most of our hypotheses were confirmed by the study, a key unexpected finding was that firms respond to both types of technological change through stronger forms of adaptation than theoretically anticipated. Firms adapt to industry technological change through an increase in the diversity of their portfolio of IORs and by churning it up, which leads to a loosening of control at the individual mode level but greater adaptivity at the portfolio level. When facing firm-specific change instead, they adapt by reducing portfolio diversity, while cutting back on collaboration across five out of the six modes. Our findings both contribute to the literature on organizational adaptation, interfirm collaboration, and IOR portfolios and provide a greater behavioral understanding of network change. 相似文献

农地整理生态环境风险综合分析与评价研究——以广西柳州市融安县为例 总被引：2，自引：0，他引：2
我国目前对农地整理产生的生态环境问题还未引起足够重视,甚至出现认识上的误区.强大的人为压力介入土地生态系统后会导致生态环境受到极大的冲击,因此,农地整理除了改善农地的生产条件,提高农地的利用率与产出率为目标外,生态环境安全也应纳入农地整理的目标之中.农地整理应关注并双重考虑区域内土地潜力与限制之间的关系.文章应用风险评价的原理和方法,对农地整理生态环境风险及其相关的评价指标体系的不确定性进行了详细的阐述,试图探讨一种新的评价方法体系,旨在对研究区内农地整理生态环境风险进行科学合理的评价,并依据此方法对广西融安县农地整理带来的生态环境风险进行了实证研究.评价结果显示研究区内风险指数可分为五级:高风险区、较高风险区、一般风险区、低风险区、微弱风险区.评价结果还表明风险等级空间分布规律与区域人文景观具有高度相关性. 相似文献
