论市场所有权

本文作者首次在国内外提出了市场所有权理论，作者认为，过去我们对企业微观产权（包括有形产权和无形产权）研究较多，而忽视了对这些微观产权赖以存在的基础和实现条件－－市场产权的研究。实际上，市场本身也有一个产权界定及其制度安排问题，本文在界定产权概念的内涵，本质与功能的基础上，认为市场产权由狭义市场所有权，市场使用权（经营权），市场占有权和市场收益权等四个要素构成，认为市场产权具有五个方面的基本特征；市场所有权的稀缺性，市场所有权的准资本属性；市场所有权的排他性；市场经营权的可转让性；市场所有权收益的可计量性等，市场产权具有三种基本形式；市场国家所有制；市场区域共享制；市场全球共享制等，虽然市场市场产权天生具有国家排他性，归一国政府所有，但市场经营可以转让，各种贸易战的实质是争夺市场经营权，控制权和收益权，区域经济一体化和经济全球化是市场经营经营权的有限互换和交叉分享。

Antecedents and consequences of corporate governance reform: the case of Germany

The paper examines the antecedents and consequences of the voluntary adoption of corporate governance reform in firms embedded in a relationship‐based governance system with less protection of minority shareholders. In such locations, ownership structure should be a key determinant of governance reform. Firms with dispersed ownership are likely to face agency problems but may lack sufficient ownership power in the hand of external owners for adoption to occur. Extensive ownership by external parties facilitates adoption but decreases the need and motivation to adopt governance reform. We examined the adoption of stock‐based incentive plans and transparent accounting regulations (e.g., greater disclosure to shareholders) among large German firms (DAX 100) during the late 1990s. We found an inverse ‘U’‐shaped relationship between ownership concentration and governance reform. In addition, we found that firms adopting governance reform were more likely to engage in corporate divestitures and achieve higher levels of market performance than firms not adopting governance reform.

Cross-hedging foreign currency risk: Empirical evidence from an error correction model

In this article, the traditional price change hedge ratio estimation method is extended by applying the theory of cointegration in the case of cross-hedging of spot exchange risk of the Belgian franc (BF), the Italian lira (IL), and the Dutch guilder (NG) with U.S. Dollar Index futures contracts. Previous studies ignore the last period's equilibrium error and short-run deviations. The findings of this study indicate that the hedge ratio estimated by the error correction method is superior to that obtained from the traditional method, as evidenced by the likelihood ratio test and out-of-sample forecasts. Hedgers will be able to control the risk of their portfolios more effectively at a lower cost.     

资本充足率监管与商业银行经营目标的路径选择

满足资本充足率监管要求和实现盈利是商业银行需要完成的两个基本经营目标。本文建立了单期模型,从理论角度分析了商业银行是如何通过调整资本金水平、存贷款总量以及风险偏好等不同的路径选择来实现上述双重经营目标。文章对我国商业银行近年来的经营行为进行实证分析表明,依靠股东注资、上市融资和发行次级债的方式已成为有效补充商业银行资本金以达到资本充足率监管要求的中长期主要路径,而调整存贷款总量和贷款组合的风险偏好是调节商业银行资本充足率水平的短期工具。在此基础上,指出国有商业银行完成上述双重基本指标是一项涉及政府、监管机构和商业银行三位一体的系统工程。     

管理层薪酬和持股激励效应的行业性差异分析--来自我国上市公司的实证证据

本文的研究以我国上市公司不同行业的实际数据为考察样本,运用实证分析方法验证我国上市公司不同类型行业管理层薪酬和持股与公司绩效之间的相关关系,分析结果表明:我国上市公司管理层薪酬和持股激励效应存在着较大的行业性差异,并提出不同行业企业应该根据自身特点和性质以及管理层薪酬和持股激励效应的大小,相机选择薪酬激励或股权激励,制定出详细周密、客观有效、切合实际的企业管理层激励方案,从而使其激励效应最大化。     

Relative accuracy and predictive ability of direct valuation methods, price to aggregate earnings method and a hybrid approach

In this paper, we assess the relative performance of the direct valuation method and industry multiplier models using 41 435 firm‐quarter Value Line observations over an 11 year (1990–2000) period. Results from both pricing‐error and return‐prediction analyses indicate that direct valuation yields lower percentage pricing errors and greater return prediction ability than the forward price to aggregated forecasted earnings multiplier model. However, a simple hybrid combination of these two methods leads to more accurate intrinsic value estimates, compared to either method used in isolation. It would appear that fundamental analysis could benefit from using one approach as a check on the other.     

Agency hazards and alliance portfolios

Prior research over several decades has catalogued many positive motives underlying firms' decisions to engage in joint ventures and other forms of alliances. In this empirical analysis, we investigate whether agency problems brought about by the separation of ownership and control also stimulate the development of firms' joint venture portfolios. By focusing on joint ventures, as opposed to diversification in general or acquisitions, we address the recent debate on agency theory's domain. Results from a sample of U.S. manufacturing firms' alliance portfolios offer supporting evidence, and comparable findings are obtained for international and domestic joint ventures. Agency hazards are also found to bring about extensions of firms' nonequity alliance portfolios in both the international and domestic settings. Copyright © 2005 John Wiley & Sons, Ltd.     

我国银行业改革与引进外资的开放竞争策略

针对我国银行业面临的问题和外资银行进入后的竞争压力,本文通过分析几种不同改革思路后认为,我国银行业改革的核心问题是产权和公司治理,两者紧密相连,产权改革是为了获得良好的公司治理,私有化和引入外资都是可供选择的产权改革方式之一,理论上不存在何者更优.国有商业银行改革的关键在于改变国有独资所有权结构为多元投资结构,可供选择的方案有不改变所有权性质的多个国有投资主体的单一所有制和引进包括国有、民营、外资参股的多元所有制.鉴于我国银行业目前的特点,外资参股并不是一种最优的选择,引进外资银行的正确策略是:独资优于合作,合作优于合资.     

中国制造业产业集聚的实证研究

文章利用集中度、基尼系数、赫芬达尔指数(N指数)等指标,对中国20个二位数制造业门类的集聚性进行了实证研究,并对其中5个门类进行了细化研究,得出结论:中国部分制造业已显现出较强的集中性,且主要集中在东部沿海省市,但一些规模经济和范围经济性强、在国外具有显著集聚特征的行业的集聚性还比较低。
