近十年来,OECD国家以多种方式加快推进教育改革,并重视培养学生“解决问题的能力”、鼓励学生使用“信息化技术”、强调“主动式学习”、强调教师专业能力特别是“批判性思考”技能。这些实践是OECD国家教育创新的亮点,对我国深化教育改革,培养21世纪创新型人才具有重要的参考意义。 相似文献

Although many scholars have demonstrated that companies engaged in collaborations achieve better environmental performance than other companies, existing studies have not analyzed in depth whether this effect changes considering the characteristics of cooperation. Our paper aims to explore whether collaboration with other companies always has a positive effect on environmental performance or whether it depends on cooperation goals, collaboration type, or company size. Empirical analysis based on a sample of 773 European companies demonstrated that an external source of knowledge is an important way to foster firms' environmental proactivity, especially when environmental goals are shared at the basis of collaboration. Second, we verified that companies involved in JVs with environmental goals achieve greater environmental performance than companies that use M&As to acquire external knowledge. Finally, we demonstrated that it is more important for small companies to be involved in environmental collaboration than larger ones. 相似文献

基于交易成本理论,在渠道合作情境下,以制造商的合同监督和企业间联合行动为工具测量合同治理的保障功能和协作功能,探讨二者对经销商主动投机行为和被动投机行为的影响差异。通过对512份问卷数据的统计分析,得到以下结论:第一,合同监督有助于抑制经销商的主动投机行为,但对其被动投机行为的影响不显著;第二,企业间联合行动有助于抑制经销商的被动投机行为,但对其主动投机行为的影响不显著;第三,经销商的主动投机行为和被动投机行为均会负向影响合作绩效;第四,经销商的主动投机行为中介合同监督对合作绩效的正向影响,被动投机行为中介企业间联合行动对合作绩效的正向影响。 相似文献

The “50/50”, or the shared management international joint venture (shared IJV) remains a popular and yet challenging control structure to govern IJVs. The purpose of this study is to understand the post-formation management of shared IJVs, specifically the relationship between shared structure, relational conditions and management of post-formation challenges. Our evidence is based on 26 in-depth interviews across four cases of shared IJVs between British multinationals and Asian companies. Our findings indicate that the highly integrative nature of shared IJVs, including high operational interdependence and shared decision-making, encourages partners to work closely together, communicate frequently and intensely and exchange personnel. Although share management can lead to inter-partner conflicts, the equal investment and mutual responsibility partly provides partners with motivation and opportunities to learn about each other, to better implement the control structure, to build trust, and to commit to the venture and partner. These relational conditions facilitated the successful management of post-formation challenges such as diversity related conflicts and macro volatility. 相似文献

The present paper investigates the relationship between the involvement of family firms in R&D collaborations aimed at developing green solutions and the value of resulting innovations. To dig into this relationship, the moderating effects of two proximity dimensions (i.e., geographical distance and technological relatedness) are also assessed. Analyses are based on a sample of 156 joint patents classified into the “Alternative energy production” field, as defined by the International Patent Classification Green Inventory and successfully filed at the United States Patent and Trademark Office in the period 1997–2010 by publicly listed companies. According to our conjectures, results reveal a positive relationship between the involvement of family firms and green innovation value. Moreover, our findings show that this relationship is hindered when partners are geographically distant or technologically proximate. Eventually, we contribute to the literature on green innovation by unveiling under which conditions inter‐firm R&D collaborations lead to more valuable innovations. 相似文献

以浙江电网企业转型现代能源综合服务的具体战略与发展规划为研究背景,针对能源综合服务系统的运行规划目标,开展基于运行规划的能源综合服务系统能效管理研究。从系统工程的视角出发,以能源流为纽带,基于多尺度能源系统建模方法,构建了能源综合服务系统模型,并结合系统综合能效,采用粒子群优化算法来优化系统各设备单元的运行策略,以实现基于运行规划的最优能效管理。通过能源综合服务系统模型计算表明,大规模清洁能源和可再生能源的接入,可以明显提高系统综合能效;随着区域用户总冷量和/或总热量需求占总电力需求的比值增大,系统最优综合能效逐渐增大;与使用内燃机、燃气轮机及汽轮机为原动机的热电联产系统相比,使用燃料电池为原动机的热电联产系统可以使能源综合服务系统综合能效更优。 相似文献

零售业自营与联营之争由来已久,在当前供给侧结构性改革、完善促进消费体制机制以及零售业寻求创新发展的背景下,有必要对这一问题展开进一步的理论探讨。文章结合马克思流通经济理论指出,自营和联营的本质区别在于是商业资本还是产业资本承担商品流通职能,自营和联营并不是非此即彼的互斥关系,但如果零售业完全倚重其中一种模式并在全社会推向极端,则需要反思商业资本和产业资本是否各得其所和高效分工。在中国流通体制变革中,虽然联营模式在特定历史时期帮助众多零售企业渡过生存危机并推进内资零售快速扩张,但发展至今,已呈现零售业普遍联营的情况,使零售业整体面临着制约创新发展的新问题。数字经济为零售业回归自营提供了有利契机,零售企业应充分利用新技术摆脱联营制的路径依赖,依托数字化开展深度自营并全面提升流通效率。 相似文献
