我国国有风险资本是否实现了设立之初的目标,即是否纾解了企业融资困难呢?文章基于上市企业微观数据和手动采集的国有风险资本数据对此进行了系统研究.实证结果稳健地显示,国有风险资本可有效缓解企业后续融资约束,我国政府参与风险投资活动是有效的.进一步地,高持股比例、多联合投资、高政治层级的国有风险资本对受资助企业融资约束的缓解作用更强;且国有风险资本对经济欠发达、低制度质量环境下的企业、面临高环境不确定性和高竞争程度企业、民营企业、成长期与动荡期企业能产生更大的影响.机制检验表明,国有风险资本既能通过认证作用显著降低企业信息不对称程度,又能发挥政治关联的资源效应,包括显著促进银企关系和企业的商业信贷获取能力,并提升企业获得政府补贴的水平,从而减轻企业资金负担,缓解其融资约束.经济后果分析表明,国有风险资本能显著降低企业外部融资的股权资金成本和债务资金成本,帮助改善企业融资贵的难题,而且国有风险资本有助于企业在创新和经营方面的良性发展.但国有风险资本并未起到有效监督作用,不能缓解企业代理问题,尤其是会导致第一类代理成本的明显提高,而高管薪酬提升是其中的重要原因.据此,文章认为在未来的国有风险资本发展中,要把握"政府角色"介入的尺度,完善国有风险资本对企业的监督管理机制.同时适当兼顾各地区发展不平衡的情况,对中西部地区的国有风险资本发展提供适当且必要的帮助,以促进国有风险资本在新时期的长足发展. 相似文献

In this paper, we investigate whether partial tax coordination is beneficial to countries within and outside a tax union, in which countries are supposed to compete in taxes and infrastructure. Our results demonstrate that a subgroup of countries agreeing on a common tax rate can harm both member and nonmember states. This is in contrast to the classical findings that partial tax harmonisation is Pareto improving. When a minimum tax rate is imposed within a tax union, we demonstrate that it does not necessarily improve the welfare of the member countries. Moreover, both the high‐tax and low‐tax countries can be worse off. This conclusion is at odds with the classical result that a high‐tax country benefits from the imposition of a lower tax bound. 相似文献

本文使用2011-2015年263家银行的年报数据和北京大学数字金融研究中心基于蚂蚁金服用户数据构建的地市级数字金融普惠指数,探究金融科技的发展对银行行为的影响。研究发现金融科技的发展实质上推动了一种变相的利率市场化,改变了银行的负债端结构,使得银行负债端越来越依赖于同业拆借等批发性资金。负债端结构的改变导致银行资产端风险承担偏好上升,但是借贷利率和净息差都有所下降。即银行选择了更高风险的资产来弥补负债端成本上升所造成的损失,但并没有将成本向下游企业转移。此外,本文还发现规模越大的银行受到金融科技的冲击越小。 相似文献

Studies that simultaneously explore the effects of sensory experience on consumer emotions and behavior are rare. This paper builds a model of buying behavior based on sensory experience, 570 valid questionnaires were obtained from coffeehouse customers. Using structural equation modeling and multiple regression analysis, this paper validates the concept model and verifies that sensory experience is a significant antecedent to buying behavior. This study indicates that certain sensory experiences significantly influence emotion. Emotion also plays a mediating role in the relationship between sensory experience and behavioral intentions. The findings are theoretically and practically profound as they address the relationships among sensory experience, consumer emotions, behavioral intentions, and buying behavior, as well as explore how the five senses affect emotions and buying behavior. This paper concludes by indicating managerial implications and research limitations. 相似文献

Previous research has shown that virtuous leader behavior in the form of benevolent leadership has considerable impact on employee creativity. However, little is known as to how and under what conditions these constructs are linked. In the current research, we proposed and tested a moderated mediation model positing leader–member exchange (LMX) as a mediator, and employee power-distance orientation as a moderator of this relationship. Two studies were conducted to test our hypothesized model. In Study 1, repeated measured data collected from 284 Chinese employees in an information technology company demonstrated that benevolent leadership had a lagged effect on LMX. In Study 2, analyses of multisource and lagged data from 391 Chinese employees in 42 research and development teams, and their direct supervisors indicated that benevolent leadership was positively related to supervisor-rated employee creativity via LMX. In addition, the relationship between benevolent leadership and LMX was stronger for employees high in power-distance orientation. Theoretical implications of benevolent leadership’s research and practical contributions concerning promoting creativity in organizations where benevolent leaders prevail are also discussed. 相似文献

This study examines why most derivatives markets that settle on the day following expiration choose the opening rather than the closing price as the final settlement price (FSP), whereas most markets that settle on the expiration day select an average rather than a single price as the FSP. Four exogenous changes in the Taiwan Futures Exchange settlement procedures provide an experimental basis for studying the settlement procedures’ impact on underlying assets. Greatest market efficiency is observed when the FSP is determined by a single rather than an average price and hypothesize that manipulation is prevented at the expense of market quality. 相似文献
