高管政治关联和企业创新投入

创新是企业获得竞争优势并在市场竞争中立于不败之地的重要源泉，但是由于市场制度的不完善，中国企业常常借助政治关联而非技术创新来开拓市场。在制度基础观的分析框架下，本文以2009-2016期间在深圳、香港和美国创业板市场上市的中国制造业企业为样本，利用HECKMAN两阶段模型和混合截面层次回归方法实证检验了高管政治关联对企业创新投入的影响，并考察了企业境外上市、中央强力反腐败斗争和行业管理决断权的调节作用。本文结果显示：（1）高管政治关联与企业创新投入之间存在显著的负相关关系；（2）相比境外上市企业，境内上市企业的高管政治关联与企业创新投入的负相关关系更显著；（3）当企业所在的行业管理决断权较高时，高管政治关联与企业创新投入的负相关关系更显著；（4）对非国有企业而言，中央开展大力反腐败斗争后，高管政治关联与企业创新投入之间的负相关关系明显增强。研究结论拓展了高管政治关联和企业创新投入的实证研究，深化了制度基础观在中国情境下的应用，具备重要的实践意义。

Next steps in implementing Kaput’s research programme

We explore some key constructs and research themes initiated by Jim Kaput, and attempt to illuminate them further with reference to our own research. These ‘design principles’ focus on the evolution of digital representations since the early 1990s, and we attempt to take forward our collective understanding of the cognitive and cultural affordances they offer. There are two main organising ideas for the paper. The first centres around Kaput’s notion of outsourcing of processing power, and explores the implications of this for mathematical learning. We argue that a key component for design is to create visible, transparent views of outsourcing, a transparency without which there may be as many pitfalls as opportunities for mathematical learning. The second organising idea is Kaput’s notion of communication and the importance of designing for communication in ways that recognise the mutual influence of tools for communication and for mathematical expression.     

高中思想政治课议题式教学的实施路径

对于高中阶段的学生来讲,学生的道德观念以及法治观念的培养是十分重要的,所以新时期的思想政治教学提出了新的要求,逐渐将问答式教学、主题式教学转变为议题式教学,这种教学方式可以有效提高学生的学习能力,进而提高学生的核心素养。但是部分教师对如何实行思想政治课议题式教学感到苦恼,对此本文就其具体实施途径进行讨论。     

探究议题式教学在高中政治课堂中的运用

随着当前社会和经济的发展,有关部门针对高中教学模式及教学理念提出了相关的调整措施。高中政治作为学生的必修科目,其枯燥的政治理论和政治思想让学生难以接受,但如果教师能够适当地调整教学模式,学生就够很好地转变学习思维。本文通过传统教学模式的叙述和议题式教学的创新对比,进一步推出高中政治课堂上应用议题式教学的理论方法。     

One country,two political cultures: What way forward for Hong Kong’s universities?

The review essay introduces and discusses Wing-Wah Law’s 2019 book Politics, Managerialism and University Governance: Lessons from Hong Kong under China’s rule since 1997, in the context of the position of Hong Kong as a formerly colonised Western enclave within a Sinic political culture, and expands on the associated issues. The book recounts on one hand the rise of managerialism and performativity in Hong Kong’s high quality universities, and on the other their enfolding in demands within the Special Autonomous Region for democratic reforms, tending towards independence from mainland China. Issues of corporatism and issues of political stability and control have coincided in disputes over the role and character of the governing councils, over senior appointments, and in relation to the freedoms of faculty and student activists. The One Country Two Systems formula, while broadly implemented, is not infinitely elastic and cannot manage a cleavage over national identity and loyalty. The differences between China and Hong Kong are more deep-seated than a tally of democratic activism and party-state repression would suggest. They go to the distinction between neo-coloniality and decoloniality and the fundamentals of political culture. The review argues that a wholly Western-style university is no longer fully viable in Hong Kong and ways need to be found to develop a more hybrid approach.
