场景化架构零售商业模式研究

文章在对场景理论进行回顾的基础上，确立了场景化架构的三要素：空间、产品和消费者，刻画了场景化架构的架构属性：空间的审美性、产品作为场景文化价值载体的媒介性、消费者对场景传达的文化价值的认同性，构建了场景化架构零售商业模式的理论模型。实证研究表明场景化架构理论模型各变量具有很好的聚合效度和区别效度，也验证了新颖性和互补性在场景化架构对体验价值创造影响的中介作用。文章的主要贡献在于提出了场景化架构这一构念，并构建了场景化架构零售商业模式的理论模型，探索和验证了该商业模式实现价值创造的内在机理，同时验证了在以往实证研究中对商业模式价值属性讨论极少的互补性是一个重要的中介变量。     

我国金融创新人才的需求预测

金融业在现代经济中发挥着极其重要的作用,而金融创新是金融业持续发展的源泉,人才又是金融创新的关键。文章首先运用GM(1,1)模型对我国2012年-2020年金融业人才需求量做了预测,随后根据2009年金融创新人才的占比,以金融业从业人员的平均增长速度作为金融创新人才需求量的平均增长速度推算出了2012年-2020年金融创新人才需求量的占比,最后根据金融业人才需求量和金融创新人才需求量的占比预测出了2012年-2020年金融创新人才需求量,并根据预测结果提出了相关的建议。     

基于三螺旋理论的瑞典政产学合作模式研究

高效的创新体系是瑞典保持国家创新能力和国际竞争力的主要原因，而政产学网络化合作模式是瑞典创新体系的核心环节。在瑞典政产学合作模式下，政府起着创新引领作用，企业起着创新主体作用，大学和研究机构起着创新执行作用，政府、企业和大学相互作用，共同合作，实现三螺旋式上升发展。在我国创新体系建设中，要进一步明确我国政府指导性与服务性的双重角色定位，重视企业的创新主体作用，实现人才培养格局的多元化并完善科技成果转化机制。     

United friction resistance in open channel flows

It is now over half a century since Keulegan conducted his open channel flow experiments.Over the past decades,many empirical formulae were proposed based on his results,however,there is still not a combined expression to describe the effects of friction over all hydraulic regions in open channel flows.Therefore,in this letter,based on the analysis of the implicit model and the logarithmic matching method,the results of Keulegan(for authentic experiment data are no longer available,here we adopt the analytical solutions given by Dou)are rescaled into one monotone curve by combining the Reynolds number and the relative roughness of the river bed.A united expression that could cover the entire turbulence regions and be validated with Dou’s analytical solutions is suggested to estimate the friction factor throughout the turbulent region in open channel flows,with higher accuracy than that of the previous formulas.

How to improve a technology evaluation model: A data-driven approach

Academic research suggests a number of technology evaluation models. To ensure effective use, models need to be improved in accordance with changing internal and external environments. However, a majority of previous studies focus on model development, while a few emphasize their implementation or improvement. To fill this research gap, this study suggests a systematic approach to examining the validity of technology evaluation models and improving them. We consider three propositions as criteria for improvement: 1) the coherence of the evaluation results with the evaluation purpose, 2) the appropriateness of the evaluation methods, and 3) the concreteness of the evaluation model. Rather than using expert opinions, this study takes a data-driven approach, wherein we analyze actual evaluation results and determine whether the model produces the intended results. A case study of 291 technology evaluation results, all made by the South Korean government in support of technology-based small and medium-sized enterprises, is conducted to verify the suggested approach's applicability. This is one of the few studies to address issues regarding improvements to a technology evaluation model. Its approach can help to develop and continuously improve a valid technology evaluation model, thus leading to more effective practice.

基于风险中性路径概率的三叉树期权定价模型

树方法是给经典期权进行定价的非常实用的数值方法,目前最流行的是二叉树模型。三叉树定价模型作为二叉树的一个扩展,其同样是在风险中性概率的基础上给经典期权进行定价,并且可以通过MATLAB实现。相比于二叉树而言,三叉树模型的定价结果具有更好的收敛性。除此之外,用三叉树模型对影响期权价格的一些因素进行敏感性分析,可以验证该模型的合理性。     

Investigating pharmaceutical logistics service quality with refined Kano's model

This study applies the refined Kano model and importance-satisfaction model to investigate medical institutions' satisfaction with and perceptions of importance of domestic pharmaceutical logistics services. Survey data involving 104 respondents from medical institutions are analyzed with importance-satisfaction and the refined Kano model. The results demonstrate that the refined Kano model will generate different classification of quality attributes for the pharmaceutical logistics industry, and medical institutions with different characteristics really have varying responses to quality attributes of pharmaceutical logistics services. The present research contributes to the literature by demonstrating that provision of high-value-added and crucial quality attributes by service providers can give them an edge in the market. In addition, when service providers understand their customers’ attitudes toward innovative service, it can enable them to strengthen their tactics in a competitive market.
