本文尝试构建一个中国OFDI(对外直接投资)技术创新效应传导机制理论框架,并对资本要素市场扭曲影响OFDI技术创新效应的作用机制和结果进行拓展分析。研究表明:近年来中国企业OFDI对技术创新具有正向效果,且OFDI企业可以通过从劳动密集型向资本密集型的转型升级、提高管理效率以及生产效率这三个重要途径实现其技术创新能力的跃升;现阶段中国资本要素市场扭曲现象会显著抑制企业OFDI技术创新效应,作用机制是,资本要素市场扭曲作为干扰外部摩擦因子,通过降低企业资本要素密集度和生产效率等渠道抑制企业OFDI技术创新效果。本文进一步提出构建知识产权金融化建议,包含知识产权股权化、知识产权证券化和知识产权流动性机制等内容,以此引导更多金融资源和人力资源参与企业技术创新活动。  相似文献

We study the market impact of a very successful financial innovation – the SPDR Gold Trust exchange-traded fund (GLD). GLD holds physical gold, and provides traders with a convenient and cost-effective way to gain exposure to gold. We find that after the introduction of GLD, the liquidity of gold company stocks declined, and their adverse-selection risk increased. Over the two-month period after GLD’s introduction, the stocks’ relative effective bid-ask spreads increased by over 15%, while their adverse-selection cost, as measured by the price impact of trades, went up by more than 30%. Gold stocks also experienced significant negative abnormal returns (−12% on average) in the month after GLD started trading. Our findings suggest that GLD attracted traders, especially uninformed traders, away from gold company stocks, and that the resulting negative demand shocks and decrease in the stocks’ liquidity caused their prices to decline. Our results show that existing securities can be seriously adversely affected when a new security enters the market.  相似文献

We use the financial crisis of 2007–2009 as a laboratory to examine the costs and benefits of teams versus single managers in asset management. We find that when a fund uses complex trading strategies involving the use of CDS team-managed funds outperform solo-managed funds. This may be due to the greater diversity of expertise, experience and skill of teams relative to single managers. During the financial crisis, however, the performance premium of teams becomes negative, which may be because of the slower decision times of teams, which are especially costly during times of rapidly changing market conditions.  相似文献

Many economists have long held that market failures create a gap between social and private returns to research and development (R&D), thereby limiting private incentives to invest in R&D. However, this common belief that firms significantly underinvest in R&D is increasingly being challenged, leading the rationale behind public support for private R&D to be questioned. In this paper, we attempt to clarify the perspectives of two sources: the theoretical literature on endogenous growth, and its recent developments in integrating a geographical dimension, and the empirical literature that measures the social returns to R&D in relation to the private returns. Ultimately, we are able to clearly distinguish among different types of market failures and compare their relative impact on the gap between the private and social returns to R&D. Two main conclusions are reached. First, systematic firm underinvestment in R&D is not demonstrated. Second, even though instances of underinvestment do occur, they are mainly explained by surplus appropriability problems rather than by knowledge externalities. This suggests the need for a new policy mix that employs more demand‐oriented instruments and is more concentrated on identifying efficient allocations among activities rather than merely increasing global private R&D investment.  相似文献

Educational policy is implicitly futures oriented, yet in most instances fails to engage learners with explicit futures tools and concepts at a school level. Futures studies in education, or futures education has the potential to reposition learning as purposeful and mobilizes the lives of participants by connecting the curriculum of schools with the multifaceted futures of learners. This is a complex task within the tensions often existing between: the cultural role of a school, the expectations of a society, the expertise of teachers, and the increasingly diverse needs of learners (Bateman, 2012). It is between the tensions of these things that the ‘ethical’ issues of what is taught, or omitted as content in a classroom and the consequences of these choices are evident.This paper highlights ethical and moral dilemmas, as they were apparent in two futures education projects. In the first study, the teachers discuss the inherent limitations of offering a broader and more futures oriented curriculum. In the second study, teachers reflect upon their students’ anxiety with regards to futures images as they are interrogated within a curriculum study. Each of these studies highlights the ethical challenges that arise, when possible, preferable and probable futures are developed as part of learning in school settings, which are culturally and demographically diverse.Tirri and Husu (2002) highlight the ethical dilemmas, which emerge in classrooms around the world, based on conflicts in values and competing intentions between key stakeholders. In the studies which contribute to this discussion, there is evidence to suggest that futures thinking causes conflict within an individual's perception of how the world should be, or their worldview as a result of futures imagining which goes beyond what is taken for granted, or is an assumed future eventuality. In the same way, Carrington, Deppeler, and Moss (2010) argue that all curriculum choices about what is taught (or not taught) in a classroom reflect an ethical decision made by a teacher, with regards to what is foregrounded for learning and what is omitted.It is crucial to re-examine the role of a school in educating students for their futures, as opposed to educating students with an aim of furthering governmental agendas. More significantly, however, as this paper highlights, it is exploring the boundaries of what is acceptable or unacceptable, appropriate or inappropriate to teach in a classroom, given the changing diversities of schools and education systems throughout the world.  相似文献

基于经验学习理论,探究创业失败经验如何通过创业失败学习影响创业者连续创业意愿,以及市场动荡性的调节作用。对176位有失败经历的创业者进行问卷调查,结果表明:创业失败经验对创业失败学习和连续创业意愿均有显著正向影响;创业失败学习在创业失败经验与连续创业意愿关系间起中介作用;市场动荡性负向调节创业失败学习与连续创业意愿的关系,即市场动荡性越高,创业失败学习与连续创业意愿间的关系越弱。研究结论对于拓展创业失败经验与连续创业意愿研究、帮助创业者从失败中复原,以及激励连续创业具有重要理论价值和实践意义。  相似文献

In an economic context, forecasting models are judged in terms not only of accuracy, but also of profitability. The present paper analyses the counterintuitive relationship between accuracy and profitability in probabilistic (sports) forecasts in relation to betting markets. By making use of theoretical considerations, a simulation model, and real-world datasets from three different sports, we demonstrate the possibility of systematically or randomly generating positive betting returns in the absence of a superior model accuracy. The results have methodological implications for sports forecasting and other domains related to betting markets. Betting returns should not be treated as a valid measure of model accuracy, even though they can be regarded as an adequate measure of profitability. Hence, an improved predictive performance might be achieved by carefully considering the roles of both accuracy and profitability when designing models, or, more specifically, when assessing the in-sample fit of data and evaluating out-of-sample forecasting performances.  相似文献

Innovation capability is critical for the modernization and competitiveness of the hotel industry. This work analyzes the role of hotels' innovative culture, market orientation, and internal marketing as forerunners of innovation capability in hotels, as well as the effect of innovation capability on hotels' performance. The proposed conceptual model is evaluated through structural equation modeling using a sample of 256 Spanish hotels. The results reveal that innovative culture by itself is not a key driver of the hotels' innovation capability. However, internal marketing and market orientation mediate the innovative culture-innovation capability relationship. Innovation capability proves to enhance hotels' market results directly and indirectly through customer equity. Our findings offer hotel managers useful guidance to understand how innovation capability is built within the firm by combining the right organizational culture and practices. Additionally, our study reinforces the financial and non-financial benefits of innovation capability in hotels.  相似文献

研发市场是经营者在特定产品和技术竞争中形成的市场范围。由于研发活动的不确定性,反垄断执法机关在界定研发市场时难以准确厘定市场边界,更深层次的原因在于维持竞争与激励研发的关系尚不明晰。研发竞争中的垄断行为难以通过相关市场界定的方式判断其违法性,需要结合具体案情和市场条件,动态分析涉案行为是否损害产品或技术研发竞争。  相似文献
