Assessing the reversal of sentiment in stock markets is needed because, according to the social mood cycle, the change of social mood over time is an antecedent of price movements. The purpose of this study is to empirically assess reversal of investor sentiment, to show the phases of social mood cycle from increasing mood to decreasing mood, and to explain the dynamic change in market inefficiency from increasing to decreasing. Growth modeling, developed particularly for dealing with the change over time, is used in this study for assessing the reversal of investor sentiment. The autocovariance structure of errors and the variances/covariances of the random coefficients are all taken into account in the model. The results have indicated that the change in investor sentiment over time is inverted U-shaped for the entire market. Moreover, arbitrage constraint and stock characteristics exert a joint moderating effect on sentiment reversal. Less arbitrage constraint can strengthen sentiment reversal only when the market for individual stocks is dominated by noise traders. Based on the results obtained, we discuss asset pricing, liquidity management, and market intervention.  相似文献

创新国际化是增强国家国际竞争力的关键。构建国家高新技术产业开发区创新国际化水平评价指标体系,以2014-2016年我国“一带一路”沿线68个国家高新区为研究对象,运用主成分分析法和二次指派程序方法对国家高新区创新国际化水平及影响因素进行实证研究。结果发现:国家高新区创新国际化以创新主体交互、创新活动融入、创新资源流动、创新绩效提升为本质特征;国家高新区创新国际化水平存在显著的区域不平衡性,东部沿海高新区创新国际化水平较高,中西部高新区创新国际化水平较低;国家高新区地理位置、经济发展、技术水平、政策质量等差异对创新国际化水平差异影响显著,自然生态环境差异对创新国际化水平差异影响不显著。  相似文献

We analyze whether product market advertising has a spillover effect on stock price synchronicity by transmitting firm-specific information to the capital market and attracting more investor attention. Using a sample of Chinese listed firms from 2009 to 2017, we find that firms with greater advertising expenditures have lower stock price synchronicity. The results are robust after we address endogeneity concerns. In accord with our hypothesis that product market advertising increases the amount of firm-level information capitalized into stock prices through the information channel, we find that the impact of advertising on synchronicity is more pronounced for firms with a higher degree of information asymmetry and firms in the consumer-product industry. Further tests show that product market advertising enhances the ability of current period returns to reflect future earnings, and thus rules out that the negative relationship between advertising and synchronicity is driven by noise trading. Our results imply that product market advertising plays an informative role and improves information efficiency in a capital market.  相似文献

本文利用企业出口决策模型阐明了技术性贸易措施对企业出口强度和市场范围的影响,并基于2010-2015年中国出口企业的微观数据进行了验证。研究表明:技术性贸易措施对企业出口规模和市场范围的扩大具有显著的阻碍作用;并且企业受影响频次比越高,负面效应越明显;技术性贸易措施影响的覆盖范围越广泛,就越能倒逼企业进行有效应对,其负面效应将有所减弱;具体到技术性贸易措施的不同类型,技术法规与标准主要制约企业出口强度的扩大,而合格评定程序则主要限制企业出口市场范围;但不管哪种类型的措施,对农产品企业的负面影响程度都会高于工业品企业。  相似文献

This paper proposes a quantile variance decomposition framework for measuring extreme risk spillover effects across international stock markets. The framework extends the spillover index approach suggested by Diebold and Yilmaz (2009) using a quantile regression analysis instead of the ordinary least squares estimation. Thus, the framework provides a new tool for further study into the extreme risk spillover effects. The model is applied to G7 and BRICS stock markets, from which new insights emerged as to the extreme risk spillovers across G7 and BRICS stock markets, and revealed how extreme risk spillover across developed and emerging stock markets. These findings have important implications for market regulators.  相似文献

This article investigates how uncertainty impacts the effect of monetary policy surprises on stock returns. Using high-frequency US data, we demonstrate that stock markets respond more aggressively to monetary policy surprises during periods of high uncertainty. We also show that uncertainty asymmetrically influences the transmission of positive and negative monetary policy surprises to stock market prices. The amplifying effect of uncertainty is found to be stronger for expansionary shocks than for contractionary shocks. Our robustness analysis confirms that financial uncertainty has a significant role in shaping the influence of monetary policy on the stock market.  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

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

本文对传统产业集群企业如何塑造区域价值链(RVC)市场势力的路径和方法进行研究,以中国南珠产业集群企业为案例,归纳、总结出传统产业集群企业在RVC市场势力塑造过程中的企业家才能和战略定位、文化认同的具体特征,析取概念并建立了“企业家才能”和“文化认同”双重作用的RVC市场势力塑造和突破攻略的理论框架。研究发现,企业家才能通过战略定位实现对传统产业集群企业的RVC市场势力塑造,通过文化认同实现对市场的控制,而在此过程中技术和市场双重控制是常规手段。在数字化条件下,利用数字手段和社会资本,与全球市场建立联结也是传统产业集群企业的一大特色。“企业家才能”和“文化认同”策略是传统产业集群企业获取RVC市场势力并成功充当国际主导企业的关键因素,发展中国家的企业可立足以文化认同为基础的RVC市场势力塑造与传递机制来驱动价值链延伸。  相似文献
