知识型员工工作自主性对建言行为的影响

基于工作特征模型理论和自我决定理论,考察了中国组织情境下工作自主性对员工建言行为的影响,检验了员工归属感的中介作用与领导正直度的调节作用。对收集到的224份有效样本进行了层次回归分析,研究结果表明：①工作自主性与员工建言行为显著正相关;②员工归属感在工作自主性与员工建言之间的关系中起完全中介作用;③领导正直度对工作自主性与员工归属感和员工建言之间的关系有显著的弱化效应,并且员工归属感完全中介工作自主性与领导正直度间交互作用对员工建言行为的影响。     

Cross‐border mergers and acquisitions: The role of private equity firms

Research summary: We show that private equity ownership (“PE backing”) of the acquirer is a signal of deal quality in cross‐border takeovers. As such, PE‐backed acquirers experience higher announcement returns in cross‐border takeovers, but only if targets are in poor information environments. We show that PE backing is a positive market signal because of PE firms' experience and networks that result from prior deals in target countries. We document that the market correctly anticipates that operating performance of PE‐backed acquirers increases as a result of cross‐border mergers and acquisitions (M&A). Managerial summary: We study cross‐border acquisitions by acquirers that are partially owned by private equity firms (“PE backing”). Cross‐border acquisitions are challenging as acquirers often have little information about targets. We document that investors react positively to cross‐border deals of PE‐backed acquirers—their stock prices increase upon deal announcements. However, this is only the case if targets are in countries with poor information environments. This is because PE backing allows acquirers to access PE firms' deal experience and networks. This makes it easier to identify and evaluate good targets, making it more (less) likely that a deal eventually creates (destroys) value. Consistent with this, we find that earnings of PE‐backed acquirers increase after buying targets in poor information environments. Copyright © 2016 John Wiley & Sons, Ltd.

我国入境旅游者流动行为机理分析——对旅游热点城市西安的实证研究

旅游者流动机理是旅游地理学与旅游者行为学交叉研究的重要内容。推—拉理论是解释游客流动原因的一种有效方法。以西安入境旅游者为研究对象,从推—拉理论的视角,运用因子分析、单因素方差分析和皮尔逊相关分析等方法对来华入境游客的流动机理进行研究,得到的主要结论有:①明确了西安入境旅游者推力维度和拉力维度的各个因子;②检测了推拉维度的各因子受社会人口统计学变量的影响;③测度了推拉维度各因子之间的相互关联性及影响因素。研究成果对指导我国各主要旅游城市进行针对性的产品开发和市场营销具有一定的实践价值,同时在理论上也拓展了国内旅游流推力与拉力之间关系研究的范畴。     

银行金融服务外包国际监管的比较研究

全球金融机构逐渐将原先自行承担的业务转交外包服务提供商完成,在这种情况下,金融机构如何控制业务的风险,如何知道自己的业务符合监管的要求是迫切需要解决的问题。本文首先分析金融服务外包所带来的风险,进而对世界上10个国家和地区的监管法律法规进行比较研究,并得出相应的政策建议。希望本文的研究结果能够对我国制定金融服务外包指引提供值得借鉴的经验。     

Shareholder Value Maximisation,Stock Market and New Technology: Should the US Corporate Model be the Universal Standard? 1

In 1992 a blue‐ribbon group of US economists led by Michael Porter concluded that the US stock market‐based corporate model was misallocating resources and jeopardising US competitiveness. The faster growth of US economy since then and the supposed US lead in the spread of information technology has brought new legitimacy to the stock market and the corporate model, which is being hailed as the universal standard. Two main conclusions of the analysis presented here are: (a) there is no warrant for revising the blue‐ribbon group’s conclusion; and (b) even US corporations let alone developing country ones would be better off not having stock market valuation as a corporate goal.     

Is there Causal Relationship between Money Supply Growth and Inflation in China? Evidence from Quantity Theory of Money

This study examines the causal relationship between Chinese money supply growth and inflation, using the bootstrap Granger full‐sample causality test and sub‐sample rolling‐window estimation test to determine whether such a relationship in China supports the quantity theory of money. The result indicates that there is a unidirectional relationship from inflation to money supply growth. However, considering structural changes in two series, we find that short‐run relationships using full‐sample data are unstable, which suggests that full‐sample causality tests cannot be relied upon. Then, we use a time‐varying rolling‐window approach to revisit the dynamic causal relationship, and the results show that money supply growth has both positive and negative impacts on inflation in several sub‐periods, and in turn, inflation has the same effects on money supply growth for China. These findings are basically consistent with the modern quantity theory of money from the perspective of money supply and price level. When money supply growth does not outweigh output growth, inflation should not be curbed only by decreasing money supply. It notes that a stable money supply growth is critical to price level stability and economic development in China.     

科技金融、企业创新投入与产出耦合协调度及不协调来源

运用耦合协调模型对中国省域科技金融、企业创新投入与产出的耦合协调度进行测度,结果显示,除北京外的中国内地省域耦合协调度整体偏低。进一步运用DEA模型进行测度发现：初始创新投入系统中各要素无效率省域分布比较复杂,企业创新禀赋无效率均值最高;创新中间产出与投入系统中,发明专利与商标权产出有效率,但以此作为中间投入的无效率均值高、省域分布广;最终产出系统中,某些省域新产品销售收入产出不足和技术市场成交额产出不足情况比较突出。据此提出创新初始投入系统协调发展观、创新中间投入与产出质量观和创新最终产出知识产权盈利模式观,以改善创新投入与产出不协调的状况,助力企业转型升级。     

HEALTH INSURANCE,FERTILITY, AND THE WANTEDNESS OF PREGNANCIES: EVIDENCE FROM MASSACHUSETTS

Health insurance reform in Massachusetts lowered the cost of both pregnancy (by increased coverage of pregnancy‐related medical events) and pregnancy prevention (by increasing access to reliable contraception). We empirically examine fertility responses and find no overall effect from increased coverage due to the Massachusetts reform. This finding, however, masks substantial heterogeneity. For married women aged 20 to 34—with high latent fertility and pregnancy wantedness—fertility increased by approximately 1%. For unmarried women in the same age range—for whom pregnancies are typically unwanted—fertility declined by 8%. (JEL I13, I18, J13)
