全球价值链视角下的中国产业供需匹配与升级研究

研究目标：更精确地反映全球价值链下中国产业供需不匹配和升级情况。研究方法：运用2016年WIOD投入产出表的数据,将中间品投入与吸收产业一一匹配以构造更微观的分类,计算出产业内贸易指数、出口技术复杂度等指数,并探讨了全球价值链嵌入对产业供需匹配的影响。研究发现：2001年以来中国产业供需不匹配程度高速增长,但增速不断降低,中国需求层面的技术复杂度水平普遍高于供给层面,而美国则正好相反;全球价值链地位、垂直专业化水平对供需不匹配程度的影响效果在不同收入水平国家间存在差异。研究创新：通过新产业分类从更微观的层面了解中国产业供需不匹配情况。研究价值：为中国未来的“供给侧结构性改革”和产业转型升级提供理论基础和政策建议。     

Bank Competition and Leverage Adjustments

We test whether bank competition affects firms’ leverage adjustment speeds. Using Chinese data where bank concentration varies across both years and provinces, we find that underlevered firms move to their target leverage faster when bank competition is high. Tests surrounding an exogenous shock to bank competition lead to the same conclusion. We also find that small firms and nonstate‐owned firms exhibit faster leverage adjustments when bank competition is high, which is consistent with the conjecture that bank risk taking increases with competition.     

Why Do Traders Split Orders?

We examine factors that influence decisions by U.S. equity traders to execute a string of orders, in the same stock, in the same direction, around the same time. Order splitting is more likely to occur when traders submit larger‐size orders and when market depth and trading activity are lower. Order splitters demand liquidity more and pay higher trading costs, but their overall performance is better. When controlling for execution time, split orders are more informative than single orders. Our results suggest that order splitting arises from a variety of factors, including informational differences, order and trader characteristics, and market conditions.     

Investors’ Fear and Herding Behavior: Evidence from the Taiwan Stock Market

This article analyzes the influence of investors’ fear on their investment behavior in the Taiwan stock market. This study used the volatility index (VIX) as a barometer of investors’ fear. Our results show that herding behavior increases with the VIX; that is, herding behavior is encouraged by an increase in investors’ fear. Moreover, our results demonstrate that investors react more quickly to bad news than to good news when their fear increases, supporting the hypothesis of the presence of an asymmetric reaction to news. However, investors react more quickly to good news when their fear decreases, indicating an inverse asymmetric reaction. In addition, our empirical results reveal that herding behavior tends to exist on days with a large trading volume.     

上市促进了企业创新吗?——来自创业板制造业企业的经验证据

本研究利用手工收集的2009-2013年在创业板市场申请上市的制造业企业样本以及企业创新专利变量,经过对成功上市企业与终止上市企业的样本匹配,运用双重差分模型考察了上市是否促进我国创业板制造业企业创新,研究结果表明,上市显著促进了企业专利创新。进一步地,我们探讨了上市促进企业创新的机制,结果发现,上市通过改善融资约束显著促进了企业创新,而上市没能通过影响代理问题作用于企业创新。该结果意味着直接金融发展有助于推动企业创新;资本市场的风险分担及融资机制能够降低企业融资约束、进而促进企业创新。这不仅为直接金融促进企业创新提供了新的证据,也为我国进一步发展与完善资本市场,进而促进经济转型、创新发展提供了新的政策启示。     

企业资源对新创上市公司创业投资决策的影响

公司创业投资（CVC）是企业外延式发展的主要路径,主要发生在大型成熟企业。近年来,我国创业板新创上市企业发生的CVC活动也比较活跃,企业资源成为影响企业选择CVC战略的重要因素。以2009-2011年在创业板上市的204家制造业企业为样本,通过其从上市至2014年12月31日之间参与的CVC数据,分析企业技术资源、财务资源和商誉资源对新创企业CVC决策的影响。通过二分类Logit实证检验发现：技术资源对新创上市企业选择CVC战略具有积极影响;充裕的现金流对新创上市企业选择CVC战略具有促进作用;商誉资源对公司创业投资决策的影响并不显著。

Managers’ Escalation Behavior in Equity Investment Decisions and the Role of Corporate Governance

The aim of this study is to investigate the relationship between free cash flows and escalation behavior in the long-term stock buying decisions for the firms listed in Taiwan. The main findings include: (1) Managers tend to exhibit the escalation behavior in the long-term equity investment. (2) There is a positive association between the level of free cash flows and the magnitude of managers’ behavioral escalation. (3) The corporate governance mechanisms play a contributory role in mitigating the escalation behavior. The evidence is robust across subsamples for electronic versus non-electronic industries, growth versus value firms, and loss versus gain firms.     

Corporate governance,SFAS 157 and cost of equity capital: evidence from US financial institutions

This study examines the association between fair value measurements and the cost of equity capital under different fair value valuation methods, and assesses the impact of corporate governance on this relationship for US financial firms. We find that firms’ cost of equity capital is negatively associated with more verifiable fair value assets and positively related to less verifiable fair value assets. Furthermore, the positive association between less verifiable fair value assets and the cost of equity capital is mitigated under better corporate governance. The differential impact between more and less verifiable assets becomes smaller for firms with stronger governance. Our findings contribute to the ongoing debate on fair value regulation by investigating the economic consequences of adopting Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157) and the importance of audit committee financial expertise on fair value reporting. We also provide evidence on the importance of board independence, internal control strength, auditor industry specialists, and audit committee financial experts in fair value reporting.
