The relevance of nonlinear internationalisation regarding exporting activities and the performance post re-entry remains little understood. This study develops a two-stage model to explain the process of exporting firms’ exit and re-entry decisions regarding individual export markets. Specifically, it investigates the dynamic relationships between exit and re-entry stages by focusing on the time-out period. This study empirically tests the decision model by employing export data from the Chinese Customs for the period 2000-2009. The results indicate the importance of the exit stage in shaping re-entry decisions, price/quality ratio and export performance, where time-out period plays a significant role in varying these effects. 相似文献

针对传统的频谱分析和自相关函数反演周期时常出现虚假周期的问题,提出了多重交叉残差法处理空间旋转目标雷达散射截面(Radar Cross Section,RCS)的时间序列。以空间跟踪和监视系统(Space Tracking and Surveillance System,STSS)卫星为例,仿真了空间目标失稳旋转状态,对比了频谱分析、自相关函数和多重交叉残差3种方法的处理结果,发现当目标存在进动运动时多重交叉残差法抗干扰能力更强。在此基础上,进一步研究了不同章动角时多重交叉残差法对旋转周期的反演效果,结果表明章动角大小会影响旋转周期的反演准确度,且章动角达到一定数值后,卫星进动幅度过大导致RCS序列周期性模糊,无法用多重交叉残差法反演出旋转周期。 相似文献

In this study, we use initial public offerings (IPOs) in China to investigate how online stock forums influence information asymmetry and IPO valuation. The empirical analysis isolates the underpricing and overvaluation components of initial returns. The number of forum comments, postings, and readings are positively associated with initial returns and the degree of underpricing, implying that forums create noise that exacerbates information asymmetry during IPOs. This effect is amplified by the quiet period regulation, which drives investors to rely on online discussion forums to obtain information. Through sentiment analyses of forum posts and media coverage, we find that the negative effect of online forums is more prominent when bad news prevails. We clarify the role of online stock forums in IPO pricing and information asymmetry by separating underpricing from overvaluation in initial returns. 相似文献

This article examines long-term labour productivity change in Japan from the early seventeenth century to the nineteenth century. We constructed sectoral labour force estimates based on the methodology presented in a previous study, who provided a sectoral GDP series covering the Tokugawa period. Our results show the industrial structure in the Tokugawa period remained relatively stable in comparison with the economy after the Meiji Restoration. Nevertheless, the estimates of sectoral labour productivity suggest expansion of the market economy in Tokugawa Japan influenced the development of industrialisation after the Meiji Restoration. 相似文献

We examine the relationship between restatements of prior period financial results and firm value in China. This relationship is relevant to the millions of global investors who purchase Chinese equity securities because Chinese regulatory authorities must focus on the restatement events that, in their judgment, most warrant investigation. We recommend that they focus their attention on restatement announcements (and the firms that announce them) that possess the characteristics that most impact firm value.Prior studies of the American equity markets found evidence of a relationship between the nature of the restatement announcements and firm value, as well as evidence that core account adjustments and high-magnitude adjustments affect firm value more than noncore account adjustments and low-magnitude adjustments. However, based on a sample of Chinese listed firms that made corporate announcements that appeared in the Asian press between 2003 and 2011, we only find mixed evidence in the Chinese equity markets in support of the former relationship, and no evidence at all in support of the latter relationship.In other words, restatement announcements in China do not impact firm value to the same extent, and in the same manner, as restatement announcements in America. Chinese regulators must thus develop policies that are unique to the Chinese markets in order to effectively prioritize their oversight activities on firms that issue restatement announcements.What factors should be considered by Chinese regulators? We identify a collection of corporate governance variables, as well as a smaller collection of financial variables, that are significantly associated with decreases in firm value. We also develop a set of regression analyses that utilize these variables to explain a significant portion of the variability of firm value during the sample period. Interestingly, however, we find no evidence that the growth patterns of the firms are significantly associated with changes in firm value.Using this evidence, we recommend the development of a model of regulatory guidance that is customized for the unique characteristics of the Chinese equity markets. We believe that this model can help Chinese authorities focus their attention on specific restatement announcements that most impact firm value. 相似文献

通过对我国改革开放以来GDP增速、煤炭消费增速历史数据的分析,发现不管是经济发展,还是煤炭发展过程中都存在周期性的波动变化规律。而通过对煤炭与经济波动曲线的拟合,发现煤炭与经济发展呈协同波动变化。基于以上煤炭与经济协同波动规律,对未来煤炭与经济发展走势进行了推演,发现煤炭消费增速最早要在2015年前后才能企稳提高,由此进入新一轮上升期。综合分析表明,煤炭抗波动能力较弱,未来要实现煤炭平稳发展,需根据经济发展节奏的不断变化,及时主动地调整煤炭发展步伐,从而避免因煤炭发展的冒进或硬着陆给煤炭及关联产业发展带来长时间、高强度的冲击和损害。 相似文献
