不要混同"公有制形式"和"公有制实现形式"

近年来，出现了将我国公有制形式与公有制实现形式混同的情况，这在理论和实践上都站不住脚。股份制“姓公”或“姓资”关键要看控股权掌握在谁手里。对于理论界和媒体对马克思著作和中央有关理论指导的误解，需要引起重视，有必要澄清理论是非，以避免理论误导可能产生的多种混乱和消极后果。     

论公司治理文化的生命周期

生命周期的概念适合于公司治理文化的研究,公司治理文化生命周期的各阶段具有其各自的特点。文章认为通过预测公司治理文化生命周期曲线上所处的位置,可以预测公司治理文化的变化趋势,解释产生变化的原因,据此制定出一系列的管理对策,以实现公司治理文化的可持续发展。     

国企改革需要新思维

国有企业改革与发展的关键之所在，就是要尽快理顺国家与企业的关系、政党与企业的关系以及职工与企业的关系，这是国有企业建立现代企业制度的根本前提。只有通过构筑企业利益共同体。通过借鉴国内外做法建立健全企业法人财产制度以及建立健全企业法人治理结构，才能真正理顺上述三者关系。国企建立现代企业制度并进而实现扭亏增盈才能真正成为现实。     

论公司法的修改与完善

《中华人民共和国公司法》在其实施的七年多时间里 ,对我国的经济发展起到了重要作用。但毋庸讳言 ,其部分条文设计的先天不足及指导思想的偏差 ,使得它与时代的要求还存在着一定的差距。本文从公司的设立条件、独资公司的取舍与规范、公司的治理结构以及如何在公司法中加强诉讼保护等方面 ,对公司法的修改与完善提出了相应的建议 ,以期对我国公司制度的成熟和发展有所裨益     

公司治理与IPO抑价——来自中国股票市场的经验证据

Jensen与Meckling(1976)认为,代理成本是投资者愿意支付的价格与公司内在价值之间的差异。投资者对公司代理成本的预期也会体现在IPO定价过程中,良好的公司治理结构有助于降低公司IPO抑价。本文以我国2002—2003年的133家IPO公司为研究样本,研究样本公司治理结构特征对IPO抑价的影响。结果发现,控制权结构特征以及关联交易性质对IPO抑价有显著的影响,而董事会独立性对IPO的抑价影响则不显著。本文的结果表明,良好的公司治理结构可以显著地降低IPO抑价,降低公司股权融资成本。     

国有股权治理与经营绩效

最近有关民营与国营企业的治理效率的讨论异常激烈,但较多的争论都是采用规范研究或者案例分析的方法,而国内较多的经济学者较早时候采用实证研究方法得出的结论大都为民营企业治理效率高于国有企业,本文采用中国证券市场运作相对成熟的1999-2003五年间的数据进行实证研究,对国有控股与非国有控股进行实证分析,得出的结论为国有控股企业平均业绩高于民营企业。这里当然有国有上市公司中一部分垄断性企业获取了垄断收益的影响,但是国有上市公司近年来不断提高业绩以及民营企业最近借壳上市后导致上市公司形成巨大亏损的事实都与本文的结论暗合。     

Inter‐temporal economies of scope,organizational modularity,and the dynamics of diversification

The question of whether corporations add value beyond that created by individual businesses has engendered much debate in recent years. Some of this debate has focused on the pros and cons of related vs. unrelated diversification. A standard explanation of the benefits of related diversification has to do with the ability to obtain intra‐temporal economies of scope from contemporaneous sharing of resources by related businesses within the firm. In contrast, this paper deals with inter‐temporal economies of scope that firms achieve by redeploying resources and capabilities between related businesses over time, as firms exit some markets while entering others. The transfer of resources due to market exit distinguishes our treatment of inter‐temporal economies of scope from standard intra‐temporal economies of scope. In addition, these inter‐temporal economies can benefit from a decentralized and modular organizational structure. This ability to obtain inter‐temporal economies of scope via organizational modularity and recombination suggests that corporations do not necessarily need a high degree of coordination between business units in order to benefit from a strategy of related diversification.

Pricing default swaps: Empirical evidence

In this paper we compare market prices of credit default swaps with model prices. We show that a simple reduced form model outperforms directly comparing bonds' credit spreads to default swap premiums. We find that the model yields unbiased premium estimates for default swaps on investment grade issuers, but only if we use swap or repo rates as proxy for default-free interest rates. This indicates that the government curve is no longer seen as the reference default-free curve. We also show that the model is relatively insensitive to the value of the assumed recovery rate.     

Do accountabilities change when public organisations transform to service systems: A new conceptual approach

In this conceptual paper, we discuss from the service systems perspective how accountabilities differ from a hierarchic and organisational perspective within the domain of New Public Management, looking to shed new light upon accountability as a research topic. The concept of service systems and their accountabilities are scrutinised and the role of integrated social and health care services is discussed in particular. The main argument in the text is the changing nature of accountabilities as the public organisations are being transformed into service systems. To date, the understanding of accountability has remained structural by nature – such is the case also for productivity measurement – but the shift from organisations towards services systems means that accountability ought to be considered as processual by nature. By processual it is meant that accountability should be considered as flows within systems – that is: flows between agents the content of which we argue includes not only knowledge on the outputs of public services, but also values, empathy and thus multi‐layered understanding of accountability. The paper concludes with practical insights for managerial purposes on the basis for this accountability shift.
