An Empirical Investigation of Trade Credit Demand

This paper investigates the motivations for a firm's demand for trade credit. Demand for credit is modelled as a function of transaction costs motivations, financing motivations, operational considerations, seller compliance issues and supplier marketing, whilst controlling for the firm's business environment and for firm characteristics such as size and industry. This paper builds on previous studies by considering a wider range of factors that can affect trade credit demand holistically on a single sample. It appears that the use of trade credit is widespread, and that it is generally perceived as an important short term financing option, although the availability of trade credit is not a major influence on supplier choice. The level of a firm's trade credit demand is found to be significantly influenced by transaction costs, financing, operational issues, marketing activities by suppliers, the firm's investment in trade debtors and firm size.     

我国畜产品产销现状与发展对策分析

本文认为,加入WTO以后,国际市场价格开始对我国畜产品市场发生作用,我国畜牧企业经营规模小、经营效率低等具体问题开始显现;面对我国畜产品消费需求的快速增长,要加快科技进步,发展畜产品加工,做大产业经营规模,构建现代化畜产品市场产销体系,提高畜产品产销效率,增强畜产品市场竞争能力;要推行市场禁入和准入制度,组建畜产品产销行业协会,加强畜产品市场定位和产销研究,积极推动我国畜产品出口,促进我国畜产品产销持续健康发展。

解决股权分置的思路:市场化全额减持流通方案

本文认为,股权分置是我国股票市场一个重大的制度性缺陷,也是阻碍市场发展与成熟的桎梏,解决股权分置问题,实现国有股权的全流通,是推进国有经济战略性重组的重要战略步骤;在我国社会主义市场化进程中,解决股权分置问题是一个系统工程,应尽可能采用市场化手段,并尽可能保证国有股流通与减持的同步实施。文章提出了市场化全额减持流通方案,充分考虑了流通股东的利益,并按照市场化竞价发售方式将上市公司国有股转移到社会公众投资者手中。该方案能够促进国有股全流通的顺利实现,解决股市顽疾,有助于推进中国国有经济的民营化,实现对国有经济的战略性重组。     

基于单因子利率期限结构模型的中国银行间短期利率行为的实证研究

文章采用高斯估计方法,使用中国银行间债券市场国债短期利率数据,对单因子连续时间利率期限结构模型进行了参数估计,实证结果显示我国银行间国债市场的短期利率具有均值恢复特性。和其它模型相比,BS模型在数据拟合方面表现较好。     

自适应约束下的双边全变差正则化超分辨率重建

在经典的双边全变差(BTV)超分辨率重建中,加权系数和正则化参数的恒定性导致重建结果边缘保持能力受限。为此,提出了一种自适应约束的BTV正则化先验模型。算法首先定义了图像的局部邻域残差均值以区分当前像素属于平坦区域还是边缘区域;然后针对加权系数的不变性导致边缘削弱的问题,利用边缘方向和垂直边缘方向扩散性的不同,设计自适应权重矩阵;最后根据代价函数的极值问题推导出迭代公式,从而进行图像的超分辨率重建,重建过程中采用自适应的方法确定正则化参数,以便求得代价函数的全局最优解,提高了算法的鲁棒性。实验结果表明：与双三次线性插值法和经典BTV算法相比,该算法取得了更好的视觉效果和更高的峰值信噪比,更多地保留了图像的边缘细节信息。     

Access to finance,working capital management and company value: Evidences from Brazilian companies listed on BM&FBOVESPA

In this research, we have analyzed the impact of financial leverage on the relationship between working capital and company value and how financial constraints on access to financing affect this relationship. In addition, we have analyzed the relationship between working capital and company value. Using a sample of Brazilian public companies listed on BM&FBOVESPA from 1995 through 2009, we found evidence for the following conclusions: an extra Real (R$) of investment in working capital is significantly less worth, on average, than an extra Real (R$) of investment in cash; and, on average, increasing the level of working capital at the beginning of a fiscal year reduces company value.     

内部控制影响国有企业竞争优势的中介效应研究

本文以2012—2019年国有上市公司为研究对象,基于公平竞争的市场环境持续改善的背景,实证研究内部控制对国有企业竞争优势的影响及作用机理。本文通过构建多元回归模型检验内部控制对国有企业竞争优势的提升效应,运用中介效应模型验证企业家精神、创新活动、融资约束在内部控制与国有企业竞争优势之间的中介作用。研究发现:内部控制质量与国有企业竞争优势显著正相关;企业家精神、创新活动与融资约束在内部控制对国有企业竞争优势的影响中存在部分中介效应。因此,可以从政府监管层面、制度层面和企业层面通过健全内部控制、激发企业家精神、促进创新活动以及降低融资约束等方式提升国有企业竞争优势。     

股权激励、契约异质性与实体企业金融化

从股权激励视角切入,利用2008—2019年沪深A股上市公司的经验数据,探究股权激励对企业金融化的影响。研究发现：从整体上看,股权激励会抑制企业金融化。基于微观契约层面,股权激励强度越大,股权激励对企业金融化的抑制程度越大;相较于限制性股票,股票期权对企业金融化的抑制程度更大;只有激励期限较长的股权激励才会抑制企业金融化。作用机制检验表明,股权激励会降低股东与管理层之间的代理成本、缓解融资约束进而抑制企业金融化。研究结论有助于充实和深化股权激励与企业金融化关系研究,也为从公司内部治理层面防范和化解实体经济风险提供证据支持。
