控股股东股权质押、市场化水平与公司风险承担

聚焦微观企业,以我国A股上市公司为样本,研究了控股东股权质押对上市公司风险承担的影响。研究发现：（1）控股股东股权质押正向影响上市公司的风险承担水平,且这种影响在控股股东持股比例较低和所处地区市场化程度较高的公司中更为显著。（2）控股股东股权质押对上市公司风险担的正向影响只有在股权质押率较高和公司存在融资约束时才会发挥作用。（3）上市公司风险承担的提高可以促进公司价值的提升,有助于公司的长远发展。     

商业银行保证金业务内部控制体系研究

巴塞尔委员会认为内部控制是现代商业银行的本质性管理行为,是商业银行风险控制的有效手段。保证金业务是我国商业银行的一项重要业务,加强对保证金业务的内部控制是提高保证金业务质量的前提条件。保证金业务内部控制体系的设计可以为保证金业务内部控制行为的顺利实施提供必要的理论指导,而保证金业务内部控制体系的设计必须密切联系于我国商业银行保证金业务的现实性实践行为。因子分析可以为理论模型提供可靠性和有效性检验,从而揭示我国商业银行保证金业务内部控制的现实状况。     

股市下行背景下股权质押对民营企业控制权与绩效的影响

随着股权质押规模的不断扩大及市场风险的不断增加,2018年我国股市出现股权质押危机.本文以2018年股价崩盘事件作为外生准自然实验,运用Logit-DID模型研究股市下行时股权质押对上市民营企业控制权与绩效的影响.研究发现:股价下跌时,若企业无股权质押,大股东会增加自身持股,降低控制权丧失风险;当企业股权质押达到一定比例,股价下跌会增加企业控制权丧失风险;企业控制权转移有损未来经营绩效,而缓解股权质押危机的纾困政策可能导致民营企业转变为国有资本控股,通过影响经理人代理问题加剧企业绩效损失.研究结论对优化资本市场监管执行、维持资产价格稳定、保护投资人与上市企业等方面具有重要启示意义.     

Determinants of patent value: Insights from a simulation analysis

This paper contributes to understanding the determinants of patent value. By drawing on a real options approach, we develop a theoretical model of patent value, which explicitly considers the uncertainty about future value. On this basis, we rely on Monte Carlo simulations with data from a case study in a large chemical firm to estimate patent value according to our model. In the simulation analyses, we compare an R&D project with patent protection and the same project without patent protection. The difference of the values of the two projects is the surplus in profit that may be expected from having a patent covering the project. This surplus is regarded as the value that is directly attributable to the patent. The results of the simulation analyses indicate that the development costs and expected net cash flows of a patent-protected project are higher than of an unpatented project. The higher net cash flows outgrow the increased development costs, and patent value is positive. However, this value is smaller than the overall project value of the patent-protected R&D project.

存货质押贷款中银行对借款人的甄别—分离均衡

抵押贷款仅考虑借款人信用风险,存货质押贷款还应考虑质物价格风险。当银行时借款人事前违约概率具有不对称信息时,在DannyBen—shahar抵押贷款模型基础上,综合考虑借款人信用风险和质物价格风险,证明存在高风险借款人选择（高利率、高贷款价值比）合同,低风险借款人选择（低利率、低贷款价值比合同）的唯一分离均衡。     

知识产权质押融资影响因素及对策——以陕西省为例

陕西省参与知识产权质押融资试点工作取得了一定的成效,但同时也面临着一些问题,如知识产权保护机制不够完善、价值评估体系不够健全、交易市场不够规范、人才储备欠缺等,影响知识产权质押融资发展。为此,提出完善知识产权保护体系、构建健全的价值评估体系、规范知识产权交易市场、加强知识产权领域人才培养等对策建议。

Are venture capitalist-backed IPOs more innovative? Evidence from an emerging market

This study examines whether venture capital (VC)-backed IPOs are more innovative than otherwise equivalent non-VC-backed IPOs. Using manually collected R&D records from annual reports and patent data from the Chinese State Intellectual Property Office (CSIPO) from 2007 to 2012, we find that VC-backed IPOs have higher R&D expenditures and more patents granted in the three years after IPOs. More specifically, they have more invention, application, and design patents in post-IPO. We use a two-stage instrumental variable, propensity score matching, difference-in-differences approach to mitigate selection biases and find our results to be consistent with our hypothesis. We conclude that VCs can positively influence IPO firms to increase R&D expenditures and innovative output levels in China. In addition, we document that the government ownership adversely affects innovation of VC-backed firms. Policy implications are discussed.     

Technological innovation and knowledge network in Asia: Evidence from comparison of information and communication technologies among six countries

South Korea, Taiwan, Singapore, Hong Kong, China and India have become much larger force in the world economy. Due to the enormous contribution of the use of information and communication technologies (ICT) in economic growth, this study investigates four main issues related to technological innovation and knowledge network in ICT among six countries. First, indicators of technological innovation were evaluated and used to compare capability of technological innovation in ICT between the six countries. Secondly, differences in innovation configurations among six countries were manifested. Thirdly, relative innovation strengths of these six countries were examined in five sub-technological fields. Finally, this study consists of analyzing the interactions into knowledge network among them; moreover, this study manifests the difference of knowledge network in five sub-technological field of ICT. The empirical findings of this study, based on analysis of a patent and citation dataset comprised of all patents granted by the U.S. Patents and Trademark Office (USPTO) to assignees in six countries from 1976 to 2006, are helpful to understand the comparative development of technological innovation of ICT in six countries.
