加快绿色创新,是采矿业企业绿色低碳发展的必由之路。基于2011—2021年采矿业沪深两市A股上市公司的数据,实证检验了碳信息披露质量对绿色创新的影响及代理成本在其中的中介作用。研究发现：碳信息披露质量对企业的绿色技术创新与绿色管理创新均有促进作用。代理成本在碳信息披露质量与企业绿色管理创新的关系中发挥了中介作用,在碳信息披露质量与绿色技术创新的关系中并未发生中介作用。进一步研究发现,碳信息披露质量对企业绿色技术创新的促进作用在非国有企业、大规模企业中更显著;碳信息披露质量对企业绿色管理创新的促进作用在国有企业、大规模企业中更显著;公众环境关注度可以增强碳信息披露质量对企业绿色技术创新的促进作用。因此,文中为采矿业企业如何推进绿色创新提供了理论支持。 相似文献

基于2015—2019年重污染上市公司的面板数据,研究环境信息披露与企业价值的关系。研究结果表明,重污染企业环境信息披露与企业价值呈"U"型关系;创新产出在环境信息披露与企业价值的关系中具有部分中介作用,即环境信息披露可通过创新产出来影响企业价值;管理层能力对环境信息披露水平与企业价值的"U"型关系存在正向调节作用。进一步研究表明,环境监管力度较强的企业,信息披露对企业价值的影响更显著。这为企业引进人才、科学开展环境信息披露、加强政府信息披露制度建设提供了经验证据。 相似文献

在理论分析的基础上,文中基于我国民营上市公司2009—2013年的经验数据,利用面板回归模型研究了民营企业政治关联对于投资效率的影响效应。研究结果表明:政治关联对民营企业投资效率具有显著负面影响,即政治联系程度的提高,投资效率越低;同时,政治关联对于企业投资效率的影响受到地区政府干预程度的调节作用,在政府干预水平较高的地区,具有政治关联的民营企业具有更低的投资效率;进一步研究发现,这种损害主要通过过度投资的方式实现。因此,应继续推进市场化改革,减少政府对经济运行不必要干预,破除民营企业投资行业壁垒,强化对民营企业金融支持,从制度环境层面减少民营企业投资效率损失以及为寻求政治联系而造成的不必要耗费,以克服政治关联对于企业投资效率的负面效应。 相似文献

随着中国双碳行动和绿色信贷政策的不断推进,碳信息披露作为外界评估企业环境风险和可持续发展能力的重要信息来源,已成为影响企业价值创造的重要因素。基于合法性理论和信号传递理论,以2015—2020年中国A股上市的高碳排放行业企业为研究样本,实证检验了碳信息披露的价值效应。研究发现：碳信息披露会抑制企业的短期价值,但可以促进企业长期价值的提升;进一步分析发现碳信息披露可以通过缓解企业融资约束来提升企业价值,但这种作用并非立竿见影的。研究结论揭示了企业的碳信息披露动机,深化理解了碳信息披露对企业价值的内在影响机理。此外,将文本分析和机器学习方法引入碳信息披露水平的研究,为该领域的研究方法提供了新的参考。 相似文献

从碳信息披露角度出发,针对我国上市公司碳信息披露情况,构建碳信息披露评价体系,考察了碳信息披露、投资者决策与企业价值三者间的内在关系,并以上证碳效率指数股为研究样本,利用联立结构方程模型对其进行实证检验。研究结果发现,在控制了其他变量后,碳信息披露对企业价值存在显著的正向驱动效应,且这一驱动效应是通过投资者决策这一中介变量部分传导的,即碳信息披露一部分直接对企业价值产生正向驱动作用,另一部分是通过先作用于投资者决策,然后再对企业价值产生正向驱动作用。 相似文献

A research group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol-a chemical found in the skins of red grapes in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 相似文献
