美联储加速退出量化宽松货币政策的影响及对我国的启示

受2013年6月美联储表态将逐步退出量化宽松货币政策的行为及其预期的影响,全球金融市场发生了剧烈地动荡,而美联储退出量化宽松货币政策的步伐却并未由此止步.这不仅会作用于美国的经济增长路径,同时也必将会使得以中国为代表的新兴市场经济体国家遭受美联储退出量化宽松货币政策的外溢性风险.文章就当前美联储退出QE预期及步伐加速的背景下,分析了美联储退出QE对全球经济的影响,以及从实体经济传导和金融市场传导层面探讨了对我国经济的影响,并认为美联储退出QE对我国而言既是一种挑战,也是一种机遇,并最终提出了以“保持稳定”为目标的防范美联储退出量化宽松货币政策溢出风险的对策建议.     

Relating in business networks: Innovation in practice

Few studies have looked at the innovation process in the early stages of new business ventures in the context of business networks. Reporting on eight years of development of a new venture, we examine how the development of initial business relationships in an ever-changing business network affects technological innovation. We conclude that technological innovation is contingent on the development of business relationships that are a critical mechanism permitting a new venture not only to access but also to produce knowledge essential for innovating. For management this implies the need to strike a judicious balance between internal focus and closure to produce novel solutions and external focus and openness to experiment in business relationships.     

Innovation forecast: Un-avoidable and context dependent

In order to mobilize the necessary resources for innovation forecasts are unavoidable. However, a forecast is never a neutral or objective assessment. Given an interdependent business landscape, there are at least two major context-related aspects that affect an innovation forecast. First, the actor that makes the forecast is embedded into a specific context. Secondly, the potential innovation stems from a specific environment, and will during the innovation journey be related to other environments in a producing and a using setting, and thus to other investments in place. In this paper we examine the development of one innovation and the forecasts made by three different economic actors. There is an interesting variation in the forecasts that can be explained as a variation of contexts of the actors. The contexts influence the way that the forecasts are done and especially in terms of what the context of the innovation is assumed to be. The empirical findings suggest that the results of the innovation forecast are highly dependent on the actors' abstraction of the business landscape which in turn is affected by the contexts of the actors.     

创新驱动产业转型升级研究——基于中国1998-2016年省域面板数据

为了探究创新驱动产业转型升级的作用机制,构建了创新投入与创新产出对产业转型升级内涵质量与外显效应的影响模型,并提出研究假设。基于中国1998-2016年省域面板数据,借助Eviews 9.0计量软件,采用固定效应模型进行实证研究。结果表明,所提出的研究假设均得到验证。创新产出对产业转型升级内涵质量具有积极影响,创新产出的各表征变量(专利授权数、技术市场合同成交金额、新产品销售收入)每增长1%,产业转型升级内涵质量的表征变量人均国内生产总值将提高0.014 8%～0.051 1%。创新投入对产业转型升级外显效应具有积极影响,创新投入的各表征变量(R&D经费内部支出、R&D人员全时当量)每增加1%,产业转型升级外显效应的表征变量产业结构层次系数将提高0.007 1%～0.010 5%。因此,创新能够驱动产业转型升级,但创新投入与创新产出对产业转型升级的影响机制并不相同。研究结果为创新驱动产业转型升级问题的研究提供了一个新的研究范式,对实施创新驱动发展战略、促进产业转型升级有借鉴意义。

Interaction between message framing and consumers’ prior subjective knowledge regarding food safety issues

This study analyzed the interaction between message frames and recipients’ prior knowledge. The hypothesis is that less prior consumer knowledge will result in a larger framing effect. That is, if the subjective knowledge of the public is low, then the controversy created by mass media regarding a specific food-related event will be larger. Empirical results show that message frame has an influence on college students’ purchasing intentions. College students showed distinct responses in purchasing intention based on different headlines and different amounts of information within articles. The results further suggest that the framing effect depends not only on message frames, but also on the prior knowledge of the message recipient. Those who have less knowledge have larger variation in their purchase intention when responding to different message frames. This suggests that people with less knowledge are more likely to panic due to mass media reports regarding a food hazard issue. More informed consumers have less dramatic responses to food safety issues compared to less informed people.     

空间视角下R&D投入对区域创新能力的影响研究——基于科技政策组合的调节作用

基于知识生产函数模型和创新地理学理论,本文利用我国30个省(区、市)2008~2020年的面板数据,通过空间计量模型实证分析R&D投入对区域创新能力的影响及空间溢出效应,并从政策目标与政策工具的耦合协调性视角理解科技政策组合,分析科技政策组合的调节效应。研究发现,我国省域创新能力呈现由东向西逐渐减弱的“梯形”分布特征;R&D资金和R&D人员对于本地区域创新能力提升具有显著的正向影响,但空间溢出效应均不显著;科技政策组合正向调节R&D投入对区域创新能力的促进作用。对此,国家应制定适宜的区域创新战略,地方政府应探索差异化创新驱动发展路径并提升科技政策组合的耦合协调性。     

境外上市与企业投资效率

截至2021年11月,我国单独境外上市企业占到境外上市企业总数的88.32%,但单独境外上市的研究明显与该数据不匹配,研究数量缺乏。为扩充该方面研究,本文以2012~2020年单独在美国和中国香港上市的中资企业为研究对象,对境外上市与投资效率关系进行检验。实证结果发现,单独境外上市与境内上市企业相比投资效率更低,区分企业上市地点后发现,规模大、信息透明度低、存在代理成本的赴港上市企业比境内上市企业投资效率低,规模小、代理成本高、信息透明度低的赴美上市企业比境内上市企业投资效率低。通过机制分析发现,信息透明度、境外上市和非效率投资三者存在"遮掩效应",境外上市企业未能受到有效的信息约束。     

碳排放约束视角下产业智能化对区域经济差距的影响研究

本文利用2003~2019年中国省级面板数据,从碳排放约束视角出发,实证考察了产业智能化对区域经济差距影响的差异性和产业智能化影响区域经济差距的机制。研究表明,产业智能化对缩小全国、东、中和西部地区省域间经济差距具有显著的正向效应;进一步考虑碳排放约束,发现碳排放约束正向调节了产业智能化对区域经济差距的正向效应,西部地区由于自身产业结构和区位因素,抑制了产业智能化对区域经济差距的正向效应;最后,对产业结构升级的两个子维度在产业智能化和区域经济差距间的中介效应检验,发现产业结构升级的中介效应存在,且主要是通过产业结构高级化实现,产业结构合理化发挥的作用较小。
