我国区际生态补偿机制研究——以京冀地区流域生态补偿为例

地方政府的有限理性导致地方利益固化,造成区际生态恶化和区际环保公共物品供给不足。以区际纳什均衡作为路径选择,试图建立旨在打破行政边界刚性约束的羁绊,突破地方政府利益固化的藩篱,以经济内在联系为协调基石的区际生态补偿机制。文章以京冀地区流域生态联防联控为例,构建区际横向生态补偿机制模型并通过最优化该模型达到区际纳什均衡。     

刺激还是抑制：企业负债对广告投入影响的理论与实证研究

以布莱德和莱维斯的理论为基础,假设广告具有拓展效应和窃取效应,研究企业负债与市场地位对企业广告投资的影响。结果显示：企业资本市场行为影响其产品市场竞争,负债具有竞争策略性;企业负债刺激其广告投入,而竞争对手负债抑制其广告投入;寡头垄断市场,企业初始市场份额抑制其广告投入;广告投入具有行业差异,且非制造业内部差异更大。研究结论拓展布莱德和莱维斯研究的同时,也给企业广告投资提供参考价值。     

基于Khatri-Rao积的3D MU-MIMO预编码方法

为了解决下行三维(3D)多用户(Multi-User,MU)多输入多输出(MIMO)系统中的共信道干扰问题,提出了一种基于Khatri-Rao积的3D预编码方法。该方法首先产生离线码本,然后各用户分别选择与水平维和垂直维信道最匹配的的码字并将其反馈给基站端,最后,根据提出的Khatri-Rao积基站端构造3D预编码矩阵,对不同用户数据进行处理。理论分析和仿真结果表明,该方法可有效地匹配真实信道状态信息(CSI),而且可有效地抑制共信道干扰,提升系统误码性能,对系统的性能优化有一定的参考价值。     

论有限责任公司股东欺压及救济

有限责任公司应为股东紧密型公司,而非人合性公司.实践中,有限公司中小股东受大股东欺压现象时有发生,其原因包括股东逐利性、资本多数决及股东退出机制不畅等.受欺压股东可以通过股权转让、行使退股权及司法解散公司请求权等方式加以救济.另外,除了完善有关法律,应充分利用公司章程在预防和化解股东欺压中的作用.     

会计师事务所转制对审计质量的影响研究——来自上市公司的经验证据

通过分析2008-2012年A股上市公司相关数据,研究会计师事务所转制对于审计质量的影响,结果显示：特殊普通合伙制会计师事务所的审计质量高于有限责任制会计师事务所的审计质量;转制后会计师事务所的审计质量高于转制前会计师事务所的审计质量,但是转制对审计质量的提高有一定的不同步性。研究结论为转制政策的合理性提供了证据支撑,也为其他中小型会计师事务所改制提供了必要性方面的经验依据。     

The Effectiveness of Two Online Persuasion Claims: Limited Product Availability and Product Popularity

Two experiments were conducted to evaluate the effectiveness of two online persuasion claims: limited product availability (e.g., only 3 items left) and product popularity (e.g., 94% of consumers bought this product after viewing this site). The popularity claim appeared to enhance quality perception, particularly among highly risk-averse consumers, and purchase intention. We attribute these findings to the quality signaling effect and the bandwagon effect of the claim. On the other hand, the limited availability claim exerted no influence: low message credibility and the lack of psychological reactance are deemed to be possible reasons for the insignificant effect of the claim.     

美国合伙制投资银行向公众公司的转变

美国投资银行起步于合伙制商号，为适应市场环境和监管规则的变化以及由此产生的内部管理需要，20世纪70年代合伙制投资银行开始向公众公司转变。由于股份制投资银行股权过度分散和股权集中度低，导致了股东对公司控制力和决策权下降，形成了“强管理层、弱股东”的委托-代理结构，造成激励约束不对等的内部治理环境，为金融危机的爆发埋下了隐患。     

The Intellectual Structure Of Research Into PPPs

Abstract

Public–private partnerships (or PPPs) encompass a broad spectrum of public sector infrastructure and service initiatives. Recently, some scholars have undertaken literature review studies of the various definitions of the concept of PPPs and its research traditions, identifying several distinct PPP research approaches. This article aims to: (1) enhance the findings of these literature reviews; (2) identify the cited works and authors (intellectual structure) in the published research on PPPs; (3) define the subfields that constitute the intellectual structure of PPP research fields. The methodology is based on the bibliometric techniques of citation and author co-citation analysis applied to published research on PPPs included in the Social Science Citation Index.     

Public–private partnerships: Task interdependence and contractibility

We examine the proper scope of public–private partnerships in the context of a project consisting of two tasks, building and operation of a facility. We investigate the optimal arrangement regarding bundling versus unbundling and private ownership versus public ownership. Like Bennett and Iossa (2006), we assume that the innovative activity in the building stage has impacts on, among other things, the subsequent operational cost. We relax the nature of task interdependence and study different contractual frameworks. The general insight is that given limitations in contractibility, contrary to common sense, complementarity between tasks favors unbundling over bundling.     

论国有企业改革与发展问题

要解决我国企业改革和发展的深层问题,必须坚定不移地建立现代企业制度。现代企业制度最本质的特征是有限责任。要建立现代企业制度,就必须进一步解决有限责任问题,主要包括:切实保障企业法人财产权不受侵犯;推进股权多元化、分散化、法人化;在加速社会保障体系建设的同时,加大力度抓好减员增效。
