IPO初始回报与创业投资参与的研究——基于我国创业板的实证研究

本文在论述国际学术界关于创业投资在企业IPO中作用理论研究的基础上,通过采用实证分析方法,对我国创业板上市的153家公司2007—2009年的数据进行研究,得出如下结论：企业IPO初始回报与是否有创业投资参与具有显著的正相关关系。同时,IPO初始回报与公司规模显著负相关,与股份发行比例显著负相关,与公司上市时年龄显著负相关,与企业上市日的上证指数收益率显著正相关,与净资产收益率显著负相关。     

基于面板数据的制造业国际R&D溢出及生产率增长途径分析

为了检验产业自身科技水平对制造业国际R&D溢出效应及产业生产率提高途径的影响,根据1999—2004年产业R&D平均投入强度,将制造业划分为高、中、低技术产业,然后基于DEA对其全要素生产率变化、技术效率变化和技术进步变化指数进行测算,最后实证检验了国内本产业、国内其它产业、国外本产业R&D资本对上述3类产业全要素生产率变化、技术效率变化和技术进步变化的不同影响。结果表明:国外R&D资本对高技术企业存在显著的正向技术溢出效应,而对于中、低技术产业来说,本产业R&D资本是生产率提高的主要来源。根据上述分析结果,对我国的产业研发投入、国际贸易政策的制定提出了建议。     

Is the leadership style important in R&D departments in Spanish industrial companies? An empirical analysis

This paper aims to thoroughly look into the effects of the differences between the diverse leadership styles on innovative outputs (intensive, efficient and eco-efficient) in Spanish industrial companies. A questionnaire for the factories was sent and was received between the months of September 2013 and June 2014. A total of 142 valid questionnaires were received. Several regression models were used in the empirical analysis. The results show that charismatic leadership positively induces an intensive innovative output, at the same time as it improves firms’ eco-efficient innovative output. Likewise, the individualised consideration that characterises transformational leadership makes this leadership style produce positive results on the whole group of innovative outputs considered. At the other end of the leadership spectrum, the transactional style causes negative effects on the relationship between innovative activity and innovative outputs, and more specifically, on the efficient innovative output.     

A comparison of Norwegian and United States accounting students' learning style preferences

Individual differences among humans are apparent in many environments and situations. Educators should be concerned about whether such differences are systematic to such an extent that they significantly affect the effectiveness of various pedagogical methods and training approaches. This paper investigates one type of individual difference-learning style-which may vary across cultures and which may be relevant for both accounting education and audit practice. Learning style is defined as an individual orientation to learning, utilizing four basic modes of learning to various degrees.

Learning style measures were obtained from Norwegian and United States accounting students with varying experience levels. The learning styles for the US students were compared to data obtained in prior research and were found to be generally consistent with these studies. The Norwegian sample was compared to both the current United States results and prior research and was found to be significantly different from the US learning style preferences. Implications of these differences for both education and practice are explored.     

Is China’s Development Finance a Challenge to the International Order?

China is a major funder of developing country infrastructure, lending $40 billion annually through policy banks. Lending does not favor the belt and road above other regions. China’s lending is indifferent to risk, that is, it is uncorrelated with indices of political stability and rule of law. Some major borrowers with poor governance are beginning to have debt sustainability problems, while other borrowers are in good fiscal shape. Chinese banks have been reluctant to follow global environmental norms but seem to be evolving in that direction. Chinese actions seem more a revision of the global system than a challenge to it.     

国家基础设施投资与区域发展战略耦合——一项抵御国际金融危机冲击的经济增长策略

为应对1997年东南亚金融危机冲击,我国政府把西部地区作为基础设施投资重点,取得了加快西部地区发展,同时刺激全国经济持续增长的成功经验。这证明,国家基础设施投资与区域发展战略耦合是一项值得重视的抵御国际金融危机冲击的经济增长策略。当前,为抵御新的国际金融危机冲击,我国政府实施了大规模的基础设施投资计划。国家宜把中部地区作为这轮基础设施投资的重点区域,以收到加快中部地区崛起步伐、营造区域热点、刺激全国经济持续增长的效果。 ?     

跨国公司研发投资的前向关联模式

经济全球化背景下,跨国公司为保持市场竞争优势和技术领先地位在全球范围内进行R&D投资,这为东道国通过产业关联获取跨国公司技术资源以提高本国产业技术水平创造了机会。从前向关联模式角度入手,研究了跨国公司与东道国本土企业通过R&D投资建立产业关联的动因、关联溢出效应及技术溢出路径,揭示了跨国公司R&D投资与东道国企业建立前向关联的内在机理,可为我国政府有效利用跨国公司R&D投资提升本土企业技术水平提供相应的管理启示和政策建议。     

论环境资源林投资的补偿机制

环境资源林投资问题是当前人们议论的热点,本文分析了影响投资梗阻的三个因素,投资额,投资期及风险,并对三种环境资源林补偿模式进行了比较,认为在政府干预下的半市场化模式较适合目前的实际状况,并提出,为了能较好地解决环境资源林的补偿问题,建立相应的补偿机制,体制风险收益的对等原则,在这一基础上,国家进行补偿收入与生态质量的行政干预。     

东道国ESP系统与东道国外商直接投资特征研究--以中国为例

国际直接投资地域结构的时空差异性对忽视东道国因素的传统国际投资理论提出了挑战。文章研究了东道国因素对国际生产资本地域运动的影响，提出了国际直接投资是东道国因素与投资主体三优势综合作用的结果，东道国环境、体制、政策系统的状态特征决定了东道国外资特征等观点，并实证研究了中国改革开放进程与外商对华投资规模和结构的内在互动性。     

基于区间数二级收敛的风险型方案的择优

区间数多属性择优问题是多属性决策研究中的重要内容.为解决成本与效益型混合的多属性风险型方案择优问题,在分析区间数的定义及其在方案属性集中应用的基础上,本文运用区间数的二级收敛思想,给出了多属性风险型方案的择优过程:首先规范决策矩阵并将各备选方案属性权重的区间数收敛为点值;其次计算各备选方案综合属性值的区间数并建立可能度矩阵再将各备选方案综合属性值的区间数收敛为点值;最后运用综合属性排序向量计算各备选方案的综合属性点值并进行排序.本文实例印证了该择优过程的实用性和有效性.本文研究成果可丰富多属性决策研究内容并有助于风险投资者科学高效地选择最佳投资方案,因而具有较高的理论意义及实践价值.
