创业意愿组织化模型将创业意愿作为新事业创建过程的起点,将\"创业意愿—机会搜寻—新事业创建决策\"看作一个组织化发展过程,将创业机会识别作为中介变量,提出关于创业意愿、创业机会识别和创业行为之间关系的研究假设和模型,并将环境不确定性作为调节变量引入模型。实证分析表明,创业机会识别对创业意愿和创业行为间的关系起中介作用,环境的不确定性对创业行为的调节作用显著。因此,具有创业意愿的创业者在识别创业机会的同时,也要关注环境的变化;只有这样,才能更好地进行创业。  相似文献

本文在考虑财政政策波动性的条件下估算了长短期政府支出乘数、政府消费性支出乘数和政府投资性支出乘数。研究结果表明:中国政府支出存在较大波动性,波峰出现在2003年、2009年、2010年、2012年、2017年和2020年;财政政策波动性是财政政策调控的一种潜在成本和重要代价,显著降低了政府支出乘数。当考虑财政政策波动性时,长期政府支出乘数、政府消费性支出乘数和政府投资性支出乘数分别为1.099、0.688、1.373,当不考虑财政政策波动性时,长期乘数分别为1.304、0.810和1.455,即财政政策波动性使长期的政府支出乘数、政府消费性支出乘数和政府投资性支出乘数损失度分别达15.7%、15.1%和5.6%;财政政策波动性使短期的政府支出乘数、政府消费性支出乘数和政府投资性支出乘数损失度分别达10.7%、8.9%和9.9%。  相似文献

本文选取2007年3月—2020年6月美元、欧元、英镑、日元和人民币三个月LIBOR-OIS和SHI-BOR-OIS数据,运用VARMA-AGARCH模型,采用网络拓扑分析法,研究美国、欧元区、英国、中国以及日本银行间市场波动性溢出效应,并构建波动性溢出指数.研究发现:国际银行间市场存在显著的波动性溢出效应,条件波动率不仅受到自身市场前期冲击和波动影响,还会受到其他市场干扰;金融危机和新冠肺炎疫情暴发期间,国际银行间市场波动性溢出效应均显著增强,并呈现动态特征;美国对其他经济体银行间市场波动性溢出最大,且在危机时期急剧上升,因此,中国银行间市场监管要防范境外市场风险跨区域传递,尤其是美国市场波动的输入性冲击.  相似文献

笔者在综合国内外创业导向相关研究的基础上发现,虽然对创业导向的研究很多,但是仍然是比较零乱的,缺乏系统性,并且国内"大家"对创业导向的关注程度不够,对这方面的研究不多。因此,笔者觉得有必要对创业导向的研究视角作个整理,目的在于发现创业导向当前研究的不足之处和需要加强的地方。  相似文献

本文主要从实证角度去考察融资融券交易机制对股票市场波动性的影响,并选取我国证券市场过去几年的相关交易数据进行实证研究。在实证中运用Granger因果检验、脉冲响应函数、方差分解等计量经济学方法进行实证验证,得出了如下结论:一是在我国证券市场中,股票指数变动是融券余额变动的Granger原因,融资融券余额变动不是融券余额变动的Granger原因,融资融券并不是造成市场波动的本质原因;二是在我国融资融券额对股票指数变动的影响都不大,融资交易相比融券交易对市场指数变动的解释程更大,并且对市场指数变动影响的持续时间更长。  相似文献

创业板市场,又称"二板市场",是为具有高成长性的中小企业和高科技企业进行融资服务的市场。2009年10月23日,我国创业板市场在深圳证券交易所正式启动,同年10月30日起正式交易。本文以我国创业板指数收益率时间序列为研究对象,运用GARCH模型对其波动性进行实证分析。研究表明:我国创业板指数收益率时间序列存在明显的ARCH效应;模型GARCH(1,1)对我国创业板市场波动性有较好的拟合性和适用性;创业板市场的波动十分剧烈,总体风险还较大。  相似文献

Taxation and Venture Capital Backed Entrepreneurship   总被引:2,自引:0,他引:2  
In recent years, venture capital has increasingly become a factor in the financing of new firms. We examine how the value of mature firms determines the incentives of entrepreneurs to start up new firms and of venture capitalists to finance and advise them. We examine how capital gains taxes as well as subsidies to start-up costs of new firms affect venture capital backed entrepreneurship. We also argue that dividend and capital gains taxes on mature firms have important consequences for start-up firms as well.  相似文献

This paper aims to describe how 27 large UK case companies sought to adapt their City and stock market disclosure policies to cope with the changes brought about by the publication in March 1994 of the Stock Exchange's Guidance on the Dissemination of Price-sensitive Information. Legislators and regulators have long sought to define and regulate the corporate decision problem in the price-sensitive information area. This paper employs corporate case interview data to describe models of corporate behaviour and to investigate how the case companies have dealt with this problem area. The paper concludes by (a), considering the effectiveness of regulation in providing a clear boundary for corporate behaviour, and (b), by discussing the relationship between this research and another major field study of corporate disclosure management (Gibbins, Richardson and Waterhouse, 1990), developing the disclosure model that they present.  相似文献

This article analyses 336 German venture capital transactions from 1990 to 2005 and seeks to determine why selected financial securities differ across deals. We find that a broad array of financial instruments is used, covering straight equity, mezzanine and debt‐like securities. Based on the chosen financial securities’ upside potential and downside protection characteristics, we provide an explanation for the differing use of these securities. Our results show that investors’ deal experience, adverse selection risks and economic prospects in the public equity market influence the selection of financial securities.  相似文献

Because the government has initiated the development of venture capital firms in Korea, independent venture capital firms have been significantly influenced by government regulations and interventions; in contrast, corporations have made venture investments internally to avoid the regulations. This study investigates whether the Korean institutional environment harms the monitoring role of independent venture capital firms, while it does not significantly impact corporate venture capital firms. In an IPO setting, we find that earnings management (long-term performance) significantly decreases (increases) with the ownership of corporate venture capital firms. However, we do not find a significant relation between the ownership of independent venture capital firms and earnings management or long-term performance. The results suggest that Korean independent venture capital firms do not play a role in monitoring their investee companies; in contrast, corporate venture capital firms play a monitoring role.  相似文献

Private Equity Syndication: Agency Costs, Reputation and Collaboration   总被引:1,自引:0,他引:1  
Abstract:  Syndicates are a form of inter-firm alliance in which two or more private equity firms invest together in an investee firm and share a joint pay-off, and are an enduring feature of the leveraged buyout (LBO) and private equity industry. This study examines the relationship between syndication and agency costs at the investor-investee level, and the extent to which the reputation and the network position of the lead investor mediate this relationship. We examine this relationship using a sample of 1,122 buyout investments by 80 private equity companies in the UK between 1993 and 2006. Our findings show that where agency costs are highest, and hence ex-post monitoring by the lead investor is more important, syndication is less likely to occur. The negative relationship between agency costs and syndication, however, is alleviated by the reputation and network position of the lead investor firm.  相似文献

Post-IPO Operating Performance, Venture Capital and the Bubble Years   总被引:1,自引:0,他引:1  
Abstract:  We analyse the post-issue operating performance of 316 venture-backed and 274 non-venture UK IPOs 1985–2003. The finding of a statistically significant five-year, operational decline exhibited over the full sample period is not robust. Rather it is driven by the dramatic underperformance during the 1998–2000 bubble years while IPOs perform normally in the remaining years. Cross-section regression results indicate support for venture capital certification in the non-bubble years but a significantly negative relationship between operating performance and venture capitalist board representation during the bubble years. The bubble year underperformance is explained by market timing and by low quality companies taking advantage of investor sentiment.  相似文献

以商标作为创新度量指标,使用1997~2008年我国24个地区的数据,运用面板Granger方法对风险投资与创新进行因果检验。实证结果表明,风险投资与注册商标都是一阶单整变量;Pedroni检验、Johansen Fisher检验和Kao检验均显著,说明风险投资和创新变量间存在长期稳定的均衡关系。基于误差修正模型的Granger因果检验结果表明,不论是在短期还是长期,均存在人均注册商标到风险投资的单向因果关系,验证了创新先于风险投资的假说;但没有发现风险投资先于创新在短期和长期内的明显证据。  相似文献
