股权分置改革——由市场走势引发的思考

股权分置改革后,沪深两市也走出了振荡中稳步攀升的走势,上证指数上涨幅度超过40％。这意味着,经过股权分置改革,资本市场“晴雨表”功能正在逐步发挥、资产定价标准趋于合理、价值投资理念逐步形成、管理层激励机制开始发挥作用以及我国的资本市场开始与国际接轨。然而现在毕竟处于股权分置改革初期,许多历史遗留问题还没有解决,因此还要通过完善新股发行的制度安排、切实解决上市公司大股东占款问题以及遏制更强烈的虚假信息披露冲动,来巩固股权分置改革的成果。     

Empirical Study on New Issue Long-term Pricing Performance ——Subject to the Hypothesis and Proof of Shell Resource Value

This paper calculates the long-term return of the IPOs in China＇s stock market, we find that the positive abnormal return of new issues lasts for 7 months after adjusted by the market return. The author explains the long-term market performance of IPOs with the concept of ＂Shell Resource＂ and supplies the related proofs.     

IPO定价机制与中国的现实选择

IPO定价机制一般分为固定价格、拍卖以及累计投标三种基本类型。中国目前实施的询价制,属于广义上的累计投标定价机制。这种定价机制中,承销商拥有的股票差别分配权利,降低了IPO抑价水平。研究表明,询价制是目前为止现实可行的定价机制。     

IPO、公司治理与企业价值——资本成本视角的理论综述

本文认为,首次公开发行上市(IPO)是企业生命周期中的里程碑。企业IPO行为改变了公司资本结构,通过资本结构对公司治理发生积极作用(融资机制、价格机制和并购机制),使得公司治理在经营者激励、信息披露、投资者保护等方面得到改善将提升企业价值,进而实现企业价值最大化的理财目标。     

Underwriter learning about unfamiliar firms: Evidence from the history of biotech IPOS

This study examines the ability of underwriters to properly value unfamiliar firms prior to issuance. I use a sample of IPOs in biotechnology, a relatively new but thriving industry. The first American biotech IPO was in 1980. Through the end of 2004, almost 500 biotech IPOs have appeared in the public market. I find that biotechnology differs from other industries in the attributes of individual firms valued by the market. In particular, R&D and the quality of human capital (e.g., star scientists on the staff) are much more important for biotech valuations. I find also that underwriters appeared not to appreciate this distinction for early biotech IPOs; in those cases, first-day market returns were predictable by firm attributes not used by underwriters to establish IPO issue prices. I also find that underwriters have learned over time, albeit slowly. Over the 20+ years of biotech history, IPO issue prices have become more dependent on firm attributes unique to biotechs while first-day market returns have become less predictable.

A comparison of revenue growth at recent-IPO and established firms: The influence of SG&A, R&D and COGS

A dynamic view of the resource based theory (RBT) examines how a firm builds its resources over time, considering variations in resources' growth rates while the firm attempts to grow. Accordingly, we consider the elasticity of accumulated resources to assess conditions where these resources might serve as substitutes for rather than complements to COGS during periods of growth. We specify a production function that links aggregate resource allocation among SG&A, R&D and COGS expenses to a firm's revenue. This function yields a set of hypotheses on the elasticity of SG&A and R&D, and the productivity of COGS, while controlling for the revenue growth rate. We test these hypotheses on a dataset of 64 randomly selected firms that recently underwent an IPO, and a comparable set of 64 established public firms from four high-technology sectors. Results show that the accumulated stocks of resources can serve as substitutes for rather than complements to COGS, and the manner in which recent-IPO firms allocate and use resources differs from their established counterparts. We discuss the implications of associated elasticity and productivity results.     

IPO初始回报与创业投资参与的研究——基于我国创业板的实证研究

本文在论述国际学术界关于创业投资在企业IPO中作用理论研究的基础上,通过采用实证分析方法,对我国创业板上市的153家公司2007—2009年的数据进行研究,得出如下结论：企业IPO初始回报与是否有创业投资参与具有显著的正相关关系。同时,IPO初始回报与公司规模显著负相关,与股份发行比例显著负相关,与公司上市时年龄显著负相关,与企业上市日的上证指数收益率显著正相关,与净资产收益率显著负相关。     

IPO抑价和市场化程度——基于中国东西部上市公司的比较研究

中国东部和西部地区的市场化程度存在显著差异,这为研究市场化程度对IPO抑价率的影响提供了难得的天然环境。笔者以1998年～2007年间来自于东部和西部地区的580个IPO为研究样本,实证分析了市场化程度在IPO抑价率形成过程中的作用,得出研究结论:市场化程度对IPO抑价率产生了负向的显著影响,该研究结论具有稳健性。依据该结论提出了相应的对策建议。     

The Effects of Public Venture Capital Investments on Corporate Governance: Evidence From IPO Firms in Emerging Markets

This study examines the impact of public venture capital (hereafter PVC) investments on corporate governance of initial public offering (hereafter IPO) firms in emerging markets. Using data collected from Taiwan PVC investments during 1996–2005, we analyse three corporate governance features in IPO firms: earnings management, board characteristics, and excess control by controlling shareholders. We find that PVC‐backed firms use fewer accounting accruals in their IPO financial statements than non‐PVC‐backed firms. This result suggests that PVC‐backed IPO firms engage in less earnings management than non‐PVC‐backed IPO firms. We also find PVC‐backed firms tend to set up their boards with fewer non‐independent directors and supervisors at IPO. This result indicates that PVC‐backed IPO firms have better board structures than non‐PVC‐backed IPO firms. Finally, we find that controlling shareholders are less likely to exert excess control in PVC‐backed firms than in non‐PVC‐backed firms. Overall, our results indicate that PVC investments add value to new IPO firms not only in financing their capital needs but also in creating better corporate governance structures in emerging markets.
