R&D投入、技术创新能力与企业经济绩效间关系的实证分析

以浙江省312家制造企业为研究对象,采用回归分析方法,对企业R&D投入、技术创新能力与经济绩效之间的关系进行了研究。结果表明:R&D投入与企业经济绩效显著正相关;新产品产出能力和发明专利申请量在R&D投入与企业经济绩效之间起部分中介作用,其中新产品产出能力的中介效应明显高于发明专利;尽管R&D投入对实用新型专利和外观设计专利的申请量有显著的促进作用,但这两类专利申请量并不是R&D投入与企业经济绩效间关系的中介变量。     

Mean-variance hedging with oil futures

We analyze mean-variance-optimal dynamic hedging strategies in oil futures for oil producers and consumers. In a model for the oil spot and futures market with Gaussian convenience yield curves and a stochastic market price of risk, we find analytical solutions for the optimal trading strategies. An implementation of our strategies in an out-of-sample test on market data shows that the hedging strategies improve long-term return-risk profiles of both the producer and the consumer.     

Guilt, Shame, and Reparative Behavior: The Effect of Psychological Proximity

Research has paid scant attention to reparative behavior to compensate for unintended wrongdoing or to the role of emotions in doing the right thing. We propose a new approach to investigating reparative behavior by looking at moral emotions and psychological proximity. In this study, we compare the effects of moral emotions (guilt and shame) on the level of compensation for financial harm. We also investigate the role of transgressors’ perceived psychological proximity to the victims of wrongdoing. Our hypotheses were tested through a scenario based questionnaire on a sample of 261 participants. Analyses indicate that (1) guilt has a stronger effect on the level of compensation than shame; (2) psychological proximity influences the level of guilt, shame, and compensation; and (3) shame interacts with psychological proximity to predict compensation, whereas guilt mediates the relationship between psychological proximity and compensation.     

More than just a utensil: The influence of drinking straw size on perceived consumption

This research replicates and extends Wansink and colleagues' research on the effect of container size on actual consumption by examining the influence of medium size of consumption (straw size) on perceived consumption. Results from two studies show that participants who used a thin straw perceived their consumption as greater than those who used a thick straw, because straw size can lead to different perceptions of consumption time. Furthermore, sip size does not moderate the effect of straw size on perceived consumption.     

捷克、波兰银行业免疫于欧债危机原因浅析

欧债危机中,捷克、波兰银行业保持平稳较快增长,文章将其原因归纳为：国内政治稳定,政府债务水平较低,劳动力具有竞争优势,与德国的经贸联系紧密,拥有独立的货币政策,未出现严重的资本外逃。文章认为两国银行业未来仍将保持增长潜力,并总结了两国银行业发展经验带来的启示。     

公共支出结构变动影响经济增长的定量分析

基于公共支出增长理论,具体研究了改革开放以来,我国公共财政支出的总量、比重及结构变化对经济增长的定量影响,揭示了各项公共支出比重的变化导致了公共支出产出弹性的变化,从而对经济增长的作用大小也发生变化.

International R&D Rivalry with Spillovers and Tariff Policies

This paper investigates the effects of R&D spillovers on the R&D choices of foreign exporters when the importing country adopts either uniform or discriminatory alternative tariff regimes. We show that the importing country should optimally choose a uniform tariff regime. A uniform tariff regime is also advantageous for foreign exporters if the R&D spillovers are sufficiently large. A comparison of free trade with the two tariff regimes reveals that there are some situations in which both the importing country and foreign exporters are better off under free trade, which supports trade liberalization.

空间思维视角下目的地旅游发展规划研究——以陕西省镇巴县为例

从空间思维理论出发,沿着确立思维空间——搜集空间信息——信息处理与空间思维决策这一思路,解读了空间思维过程,尤其对点式思维、线式思维、面式思维、体式思维等思维决策方式进行了重点探讨。最后,将空间思维理论应用于旅游发展规划之中,并以陕西省镇巴县旅游发展规划为例,进行实证研究。     

循环产业集群是西部跨越式绿色发展的有效途径

在新的历史条件下,西部欠发达地区必须走跨越式绿色发展之路.文章从产业组织的视角出发,分析比较了产业集群与循环经济模式单独运行的优劣势,研究了西部要实现跨越式绿色发展的可能途径.研究结果表明,仅仅依靠传统的产业集群和单一的循环经济模式无法实现西部地区的跨越式绿色发展,只有采用循环产业集群这一新型的产业组织模式,才能真正实现经济效益和生态效益的双赢.因此,循环产业集群确实是西部欠发达地区实现跨越式发展的有效途径.
