    以Graham和Harvey(2001)为代表的学者们所进行的问卷调查结果表明,在公司财务实践中,财务灵活性原则是高管们制定财务决策时的经验法则。财务灵活性在财务实践中的重要性已经获得了西方国家财务高管们的一致认同。而在财务灵活性对公司资本结构决策、现金持有量决策和股利决策影响的实证研究中,西方学者们也取得了初步的证据支持。然而,学者们对于财务灵活性在公司财务决策中的作用机制仍然缺乏共识。厘清财务灵活性对公司财务政策的影响机制,对其进行系统性研究,成为亟待解决的问题。相较于西方成熟的资本市场而言,我国资本市场尚不完善。对于我国上市公司而言,财务灵活性更有价值,对公司财务决策的影响应当更为显著。...Survey evidence provided by Graham and Harvey (2001) and other scholars have demonstrated that the principle of financial flexibility is considered as “Rule of Thumb” in financial decisions by financial executives. The importance of financial flexibility in financial practices has been agreed by financial executives in Western countries.

    上市公司财务灵活性、再融资期权与股利迎合策略研究

    Get PDF
    2006年和2008年,证监会分别出台了两项将上市公司股利分配水平与再融资资格挂钩的半强制分红政策。本文以此为背景,将再融资资格看作公司的期权,首次从财务灵活性的角度探讨期权价值的大小,构建我国上市公司股利迎合策略的分析模型,对该股利行为的决策机制和经济后果进行了实证研究。研究结果表明:财务灵活性是理解公司在半强制分红背景下股利行为的关键因素。2008年政策中限定股利分配形式仅为现金股利的规定提高了高成长性公司的融资门槛,可能导致监管悖论。实际上,在公司根据财务灵活性进行自利选择的过程中,市场资源得以优化配置,因此监管当局应该减少在再融资资格筛选中的行政干预,加速资本市场的市场化进程

    资本结构、管理层防御与上市公司高管薪酬水平

    Get PDF
    将人力资本破产成本引入研究框架是高管薪酬理论研究的新突破。其他条件相同时,公司的资产负债率越高,破产可能性就越大,高层管理者因而要求更高的薪酬水平以补偿所需承担的更高的人力资本破产成本。可见,公司资本结构因暗涵了人力资本破产成本,可作为衡量高管薪酬是否合理的依据。本文以2004-2007年上市公司为样本,从资本结构的视角来审视上市公司的高管薪酬,并探究公司管理层防御现象。研究发现:(1)我国上市公司普遍存在管理层防御现象;(2)平均而言,国有企业高管薪酬水平高于民营企业,但资本结构相近,因此,相比于其所承担的人力资本破产成本,国有企业高管的薪酬水平太高了;(3)与民营企业相比,国有企业存在着更为严重的管理层防御问题

    The influential mechanism of macroeconomic environment, value creating ability and capital market efficiency

    近十年来,我国宏观经济实现了10%左右稳步、快速的增长,然而,资本市场指数上涨幅度仅约为4.64%。实体经济的价值创造、宏观经济环境的影响、资本市场效率,共同导致了我国目前资本市场发展与宏观经济增速不相匹配的问题。 从我国资本市场建立伊始,就旨在通过社会资本的有效配置,促进实体经济发展。然而,实体经济的发展也是资本市场发展的基础,资本市场的发展同样需要实体经济的价值创造能力作为支撑。因此,在上述问题当中,首要解决的是实体经济创值能力的度量问题,进而探讨其影响因素和影响机制,最后检验实体经济创值能力对资本市场效率的影响。 现有研究表明,学者们普遍认同采用经济增加值(EVA)来度量公司的价值创...In recent decade, China has experienced over 10% economic growth, whenever the capital market index has just increased about 4.64%.

    How Geography Influences Dividend Policy: " Substitute Model" or "Outcome Model" ?

    本文以“替代模型“和“结果模型“归纳了地域因素对公司股利政策两种可能的影响路径,并首次从财务灵活性和成长性的视角厘清了该影响路径的具体作用机制,完善了研究地域因素影响公司股利政策的理论分析框架。实证证据一致表明,地域因素对我国上市公司股利政策的影响机制支持“结果模型“,即地处边远地区的公司由于面临更高程度的信息不对称水平,不得不更多地依赖债务融资,导致其剩余举债能力不足。债务的刚性和潜在的资金需求缺口提高了财务灵活性对边远地区公司尤其是高成长性公司的价值,使它们对财务灵活性的需求更为迫切。在受到外部融资约束的情况下,边远地区公司更倾向于通过减少现金股利发放的方式,来保留公司的财务灵活性。This paper defines possible influences of geography on dividend policy as "substitute model" and "outcome model",and figures out the influential mechanism from the perspective of financial flexibility and growth opportunity for the first time,which clarifies the analysis framework when discussing geographic influences on dividend policy.Our empirical results consistently support the "outcome model".It indicates that,companies who are in remote places are facing higher level of external financial constraint because of higher level of information asymmetry,which makes them depend more on debt financing,and get less spare debt capacity as a result.Hence,compared to companies located in central places,remote firms,especially for those with higher growth opportunity,will have higher needs for financial flexibility,which finally leads to their lower payout.国家自然科学基金项目(71472160); 中国博士后科学基金面上项目(2014M551435); 教育部高等学校博士学科点专项科研基金项目(20120121110041)的资

    本文将2006-2007年深沪两市公司定向增发样本分成三组:仅针对大股东及关联方发行组、仅针对机构投资者发行组以及混合发行组进行比较研究,发现仅针对大股东和关联方发行组存在通过刻意打压定价基准日股价、提高折价幅度等手段以达到降低增发价格、向大股东及关联方输送利益的目的。通过对比样本公司定向增发前后关联交易量,我们还发现,样本公司关联交易总规模、平均单笔交易规模都在定向增发后呈现显著上升趋势,进一步验证了上市公司在定向增发后通过关联交易进行财富转移的可能。Private placement is defined as the behavior that listed companies issue stock to specific groups through non-public way.In developed markets,private placement can be regarded as an efficient mechanism for market to optimize resources allocation.In Chinese market,private placement did not become a desirable choice for both listed companies and investors until the Chinese Securities Regulatory Commission issued"Management Approach of Listed Companies’ Security Issuance"on May 7,2006.However,there is still no requirement about profitability for companies who issue private placement, and the requirements for choosing the pricing benchmark date and the minimum pricing level of issuing are vague,making it possible for controlling shareholders and related parties to tunnel through private placement.Whether listed companies make rent-seeking and how they tunnel through private placement are both new issues which need to be solved.In this article,we expect to break through the status quo,and use specific empirical research design to find out the solution to these new questions.This paper divided the whole sample of listed firms that conduct private placement from the year 2006 to 2007 into three groups to investigate the announcement effect of private placement.One is the group of large shareholders,another is the group of institutional investors,and the third is the group which does not belong to the two groups referred before.The results show that nearly 25 days before the pricing benchmark date the cumulated abnormal return decreases significantly for the group of large shareholders,giving some evidence of their tunneling through announcing bad news to lower the stock price.Furthermore,the comparison of related trading volume before and after private placement shows that both total and average volume experience significantly increase after the private placement,which supports the view of transferring wealth through private placement in another aspect.国家自然科学基金资助项目(70472048);国家自然科学基金重点项目(70632001);福建省科技计划重点项目(2008R0058)资
