基于代理理论的经营多元化对企业业绩的影响研究

基于中国制造业上市公司2003～2009年的财务数据,讨论多元化经营和企业内部代理对企业业绩的影响,结果表明:多元化经营对企业业绩具有负向影响,股东与管理层之间的代理成本、经理层之间的代理成本对企业的业绩具有显著的负向影响,控股股东与中小股东之间的代理问题对企业业绩不具有负向影响;多元化经营导致企业股东与管理层之间代理成本增加,同时使得控股股东与中小股东之间的代理成本减少。     

企业内部资本市场对现金持有及其价值的影响——基于我国上市公司面板数据的实证分析

本文以2005-2011年中国A股上市公司为样本,实证分析内部资本市场对企业现金持有量的影响,并在此基础上进一步研究集团多元化和国有控股是如何影响企业现金持有及其价值.研究结果显示：内部资本市场增加了上市公司的现金持有量,但却显著折损了公司价值,内部资本市场加剧了企业持有现金的代理动机;国有控股集团在一定程度上缓解了上市公司的融资约束,但却未能提升公司的价值;多元化经营的集团公司现金持有量也偏低,但并非出于其缓解融资约束的作用,且呈现出显著的现金持有“多元化折价效应”.     

民营公司两权分离度、内部制衡机制与经营绩效关系

以中国的投资者保护为研究出发点,本文搜集沪深两市挂牌交易的由自然人创立并拥有的民营公司研究样本,实证检验其两权分离程度、内部制衡机制与公司经营绩效之间的关系。研究发现,在民营公司内部,控制权和所有权的分离对公司的经营绩效产生了显著的负面影响,两权分离程度越大,对公司经营绩效的负面作用越大;其次,内部制衡机制与公司经营绩效显著正相关,制衡机制越强,抑制终极控股股东的侵占行为的效果越显著;最后,两权分离程度与内部制衡机制之间存在着交互作用,在两权分离程度相同的情况下,制衡机制的程度越强,对于减少终极控股股东与中小投资者之间的委托代理成本,改善公司经营绩效的效果越明显。     

关系股东与融资约束——基于系族集团的经验证据

已有研究指出,控股股东的关系股东加剧了控股股东与中小股东间的利益冲突.关系股东是否具有积极的一面,研究中尚缺乏关注.本文以2003-2017年间附属于系族集团的A股上市公司作为研究样本,实证检验了系族成员关系股东是否以及如何影响融资约束.研究发现,相对于没有关系股东的系族成员,有关系股东的成员企业面临的融资约束更低,在考虑内生性问题后结论依然稳健.进一步研究表明,关系股东通过降低实际控制人与成员企业的信息不对称、促进内部资本市场资源优化配置,以及降低管理层代理成本从而缓解所在成员企业的融资约束.本文揭示了关系股东对融资约束的影响及作用机理,丰富了关系股东与内部资本市场经济后果方面的研究.     

内部资本市场 公司绩效与控制权私有收益——以华通天香集团为例分析

基于内部资本市场理论,当企业集团对内部各成员部门不是100%控股时,资源在内部资本市场的转移会产生较大的摩擦,内部资本市场存在效率不足。在处于转轨时期的中国企业,公司治理尚不完善、代理问题比较严重,势必影响内部资本市场功能的正常发挥。本文以华通天香集团为例,分析了上市公司内部资本市场运作的主要路径及产生的经济后果,发现原本在于提高资本配置而存在的内部资本市场部分地被异化为进行利益输送的渠道。另外,在本例中没有发现企业进行明显的跨部门交叉补贴证据。     

大股东资金占用对上市公司影响──基于阿继电器的案例分析

在中国资本市场中,许许多多的上市公司存在着大股东占用资金的问题.从相关统计来看,如果上市公司连续两年都为亏损状态,则超过70%的大股东都有着侵占资金的情况;而对于已经退市的上市公司而言,控股股东侵占资金的行为是其经营失败的根本原因.由此可见,大股东占款对上市企业乃至中国资本市场都有极大的负面影响.阿继电器为一家上市公司,其最大股东阿继集团的资金占用行为,对阿继电器的盈利能力、偿债能力以及财务报表具有很大影响,成为了阿继电器的沉重负担.     

企业集团内部资本配置对成员企业价值的影响

创造内部资本市场的能力是企业集团十分显著的特征。企业集团内部资本配置对其成员企业价值是有影响的。本文通过对中国企业集团控股公司的实证检验发现，内部资本配置对国有集团控股公司的价值有反方向的影响；对民营集团控股公司的价值有显著的正向影响。在控制权大于现金流权组，集团内部资本市场的规模越大，其对控股公司的价值影响越大；但对多元化经营和规模越大的集团控股公司的价值影响较小；在控制权等于现金流权组，其内部资本市场规模越大，其控股公司的价值越小，尤其对多元化经营的集团控股公司的价值的影响越小。     

股权质押与公司估值:理论与实证

本文基于2000—2020年我国A股上市公司数据,探讨了控股股东股权质押对上市公司代理问题及其估值的非线性影响。研究发现,控股股东股权质押比例较低(高)时将会缓解(加剧)上市公司的代理问题,从而使其估值上升(下降)。进一步分析显示,随着控股股东股权质押比例的提高,上市公司的财务约束和财务困境水平先降后升,呈U形变化;与此同时,控股股东高股权质押比例降低了上市公司增量现金的边际价值,增加了其审计费用和违规频次。从企业异质性来看,国企子样本中上述关系大多不显著。本文研究对进一步理解股权质押的内在运行机制和经济后果有一定参考意义。     

信息披露质量 控股股东资金占用与公司价值——来自深市A股上市公司的经验证据

资本市场中存在的信息不对称加剧了控股股东对中小股东的利益侵占。信息披露作为一种旨在减轻信息不对称程度的机制,有助于提高上市公司的透明度,保护中小股东利益。本文以2007-2009年深市A股上市公司为样本,实证检验了信息披露质量对控股股东资金占用的影响。研究发现,控制相关因素后,信息披露质量与资金占用呈显著负相关,提高信息披露质量可以有效地降低控股股东资金占用;进一步研究发现,控股股东资金占用越少的公司价值越高,并且相比而言,信息披露质量越高,公司价值也越高。     

集团财务公司对其成员单位价值的影响效应

我国集团财务公司虽被赋予加强企业集团资金集中管理和提高企业集团资金使用效率的职责,但通过文献梳理,未发现支持性论证,甚至有文献提出因财务公司帮扶性质,导致资金未得到优化配置。本文根据集团财务公司信息,确认其所属集团,进一步以集团控股上市公司作为研究样本,检验集团财务公司对成员单位价值、负债水平和债务成本的影响。结果表明:集团财务公司成立前样本账面价值明显优于成立后,成立前后市场价值的差异不明显;集团财务公司成立后样本公司负债水平显著增加,财务费用率变化不明显。上述结果说明集团财务公司成立并没有增加其成员单位价值。     

一损俱损:违规事件在企业集团内的传染效应研究

本文以企业集团为对象,研究违规事件的传染效应。利用2003-2015年我国上市公司违规样本,本文发现:(1)当公司发生违规行为而被证监会等监管机构进行处罚公告后,违规公司股价显著下跌的同时,同一集团内其他公司的股价也显著下跌,即违规事件在集团内存在传染效应,而这一传染效应主要存在于与信息披露相关的财务违规事件中;(2)进一步的路径检验发现“被传染公司”较低的盈余质量和集团内财务公司的存在能够解释传染效应的发生;(3)分组检验结果表明:集团内的传染效应在地区市场化程度较低、分析师跟踪人数较少、股权集中度较高的公司和国有企业中更为明显。借助违规事件的传染效应研究视角,本文的研究结果有助于进一步认识新兴市场中的企业集团。     

Emerging Derivatives Markets: The Case of Chile

We compare the performance of firms affiliated with diversified business groups with the performance of unaffiliated firms in Turkey, an emerging market. We address the question of whether group-affiliated firms create internal capital markets or control large cash flows. Our findings indicate that group affiliation improves a firm's accounting performance, but not stock market performance. Deviation of cash-flow rights from voting rights has a negative but insignificant effect on accounting performance, but a significant effect on market performance. We also find that a firm's accounting, but not stock market, performance increases with the level of group diversification. Our results show that internal capital markets play an important role for the existence of business groups in an emerging market context.     

The Beta Dilemma in Emerging Markets

In principle, emerging markets analysts employ the same analytical framework when estimating the value of businesses as their counterparts in developed economies: they forecast future cash flows and discount those to the present with appropriate costs of capital that are estimated using the Capital Asset Pricing Model (CAPM) framework. But in practice, emerging market analysts have a more complicated job because the task of estimating costs of equity in emerging markets is more difficult. Whereas developed economies have an abundance of historical data on overall stock market movements, industry share price behavior, and many individual share price histories, emerging market economies often do not. There may be no comparable local firms that are publicly traded—or if there are, their CAPM betas may be unreliable. And if analysts instead use the beta of a U.S. competitor as a surrogate for the emerging market beta, they face the question of whether domestic betas are equivalent across borders. As a consequence, appraisers of emerging market companies confront a “beta dilemma.” Part of this is a data problem stemming from shorter share price histories in emerging markets and the absence of publicly traded companies in some industries. In such cases, analysts may be inclined to use industry betas calculated with U.S. share prices as a substitute. But this creates an equivalence problem—the possibility, as confirmed by the author's research, that domestic U.S. and emerging market betas are not statistically equivalent for most industries. The author proposes a solution to this problem that involves grouping emerging markets into a single, distinctive asset class that allows for reliable calculations of industry betas. He also suggests ways of testing emerging market industry betas to determine whether they are statistically comparable.     

Labor cost voluntary disclosures and firm equity values: Is human capital information value-relevant?

This study examines the market value relevance of labor cost voluntary disclosures using a valuation model relating firm market values to book values of equity and to disclosed human capital information, such as labor costs, net pension liabilities (NPLs), and estimated average and marginal labor productivity and efficiency indicators. Results indicate that labor cost disclosing companies command higher equity market values in general, and that labor productivity and efficiency measures appear to be undervalued. Both findings suggest that there might be market opportunities for firms with valuable human capital to differentiate themselves from their industry peers, which might encourage further human capital disclosure in the future. More refined measures of human capital assets and investments are needed to assess firms’ human resource management decisions and performance impacts in the capital markets more adequately.     

Is There a Size Effect in the Pricing of Stocks in the Chinese Stock Markets?: The Case of Bull Versus Bear Markets

Size effect studies generally suggest that a return premium exists for small firms. While the size effect has mostly disappeared in recent years in mature markets (e.g., US and UK), it remains mostly strong in developing markets. The purpose of this paper is to examine the relationship between firm size and excess stock returns in the Chinese stock markets, and to examine this effect in both a bull and bear market. No studies have previously examined these relationships in the Chinese markets. The results of the study indicate that a size effect exists in the Chinese stock markets over the 6-year period from 1998 to 2003. We find small firms have significantly greater excess returns than large firms. Moreover, small firms are found to have a stronger reaction to the direction of the market than large firms. Small firms have significantly greater positive excess returns than large firms during the bull market. However, small firms have significantly greater negative returns (using total market value), or no significant difference in returns (using float market value) during the bear market period.     

Is Group Affiliation Profitable in Emerging Markets? An Analysis of Diversified Indian Business Groups

Emerging markets like India have poorly functioning institutions, leading to severe agency and information problems. Business groups in these markets have the potential both to offer benefits to member firms, and to destroy value. We analyze the performance of affiliates of diversified Indian business groups relative to unaffiliated firms. We find that accounting and stock market measures of firm performance initially decline with group diversification and subsequently increase once group diversification exceeds a certain level. Unlike U.S. conglomerates' lines of business, and similar to the affiliates of U.S. LBO associations, affiliates of the most diversified business groups outperform unaffiliated firms.     

GOLBALIZATION, CORPORATE FINANCE, AND THE COST OF CAPITAL

International financial markets are progressively becoming one huge, integrated, global capital market—a development that is contributing to higher stock prices in developed as well as developing economies. For companies that are large and visible enough to attract global investors, having a global shareholder base means having a lower cost of capital and hence a greater equity value for two main reasons: First, because the risks of equity are shared among more investors with different portfolio exposures and hence a different “appetite” for bearing certain risks, equity market risk premiums should fall for all companies in countries with access to global markets. Although the largest reductions in cost of capital resulting from globalization will be experienced by companies in liberalizing economies that are gaining access to the global markets for the first time, risk premiums can also be expected to fall for firms in long-integrated markets as well. Second, when firms in countries with less-developed capital markets raise capital in the public markets of countries (like the U.S.) with highly developed markets, they get more than lower-cost capital; they also import at least aspects of the corporate governance systems that prevail in those markets. For companies accustomed to less-developed markets, raising capital overseas is likely to mean that more sophisticated investors, armed with more advanced technologies, will participate in monitoring their performance and management. And, in a virtuous cycle, more effective monitoring increases investor confidence in the future performance of those companies and so improves the terms on which they raise capital. Besides reducing market risk premiums and improving corporate governance, globalization also affects the systematic risk, or “beta,” of individual companies. In global markets, the beta of a firm's equity depends on how the stock contributes to the volatility not of the home market portfolio, but of the world market portfolio. For companies with access to global capital markets whose profitability is tied more closely to the local than to the global economy, use of the traditional Capital Asset Pricing Model (CAPM) will overstate the cost of capital because risks that are not diversifiable within a national economy can be diversified by holding a global portfolio. Thus, to reflect the new reality of a globally determined cost of capital, all companies with access to global markets should consider using a global CAPM that views a company as part of the global portfolio of stocks. In making this argument, the article reviews the growing body of academic studies that provide evidence of the predictive power of the global CAPM as well as the reduction in world risk premiums.     

Too few dividends? Groups' tunneling through chair and board compensation

Group affiliation increases boards' compensation in countries as different as Korea, India, Hong Kong and Italy. In this paper, I examine a 6-year sample of controller-dominated, concentrated-ownership firms in Chile in search of a rationale for these results.I show that, for group-affiliated companies, controllers' presence on the board of directors is associated with a strong negative relation between chair and board compensation and controllers' cash-flow rights. Furthermore, I show that controllers of group-affiliated companies prefer to increase chair and board compensation rather than dividends as their cash-flow rights decrease.     

Group-Affiliated Analysts’ Strategic Forecasts During a Year: Evidence from Korea

In examining the family-controlled business groups in Korea, prior literature shows that group-affiliated analysts’ forecasts are optimistically biased. This article investigates whether the group-affiliated analysts strategically time the level of accuracy and bias in their forecasts for the same group-affiliated firms due to the change in information asymmetry in the market. The results show that the group-affiliated analysts issue more accurate and less optimistic earnings forecasts for the affiliated firms when the level of information asymmetry is low; particularly, in April, which is right after annual earnings announcements.     

CAPITAL MARKET EXCESSES AND COMPETITIVE STRENGTH: THE CASE OF THE HARD DISK DRIVE INDUSTRY 1984–2000

In a much-cited 1985 study of the U.S. hard disk drive industry entitled "Capital Market Myopia," William Sahlman and Howard Stevenson concluded that "excesses in the capital markets turned an opportunity into a disaster" for investors in the emerging industry. Sahlman and Stevenson fretted about what their findings implied not only for investors but also for the industrial competitiveness of the U.S.A.
With the benefit of hindsight, the research presented in this article shows how the hard disk drive industry has evolved in the past 15 years to the point where disk drives are a vital part of the information technology revolution that has transformed the way we live, work, and play. The authors' research examines the financial performance of both hard disk drive manufacturers and storage system manufacturers completely dependent on hard disk drives; looks at improvements in the technical performance of hard drives; and then compares the competitiveness of U.S. companies with foreign manufacturers.
After the venture capital/IPO bubble of the early 1980s gave way to the traditional discipline of U.S. financial markets, many weak companies were driven out of business and others were forced to consolidate. Only a handful of the startup firms survived. But these U.S companies, together with IBM, now dominate the global hard drive market. Moreover, there are striking parallels between the 1982–84 hard drive bubble and the recent experience of U.S. Internet firms. Although the first half of 2000 saw a large number of closings, forced sales, and IPO cancellations by American dot-coms, a number of the likely "survivors"—notably, Yahoo, eBay, and Amazon.com—now seem poised to dominate their global markets.
