Strategic product showcasing mode of E-commerce live streaming

E-commerce live streaming can considerably help brands improve sales dynamics, but it is multiple dilemmas in choosing suitable e-commerce live streaming product showcasing modes. To address the multiple dilemmas, we first employ the Stackelberg game to depict three e-commerce live streaming product showcasing modes: brand self-live streaming, influencer-led live streaming mixture, and influencer-led special live streaming. Second, we analyze the relationship between choices and game parameters, including live streaming stimulus sensitivity, unit service quality improvement cost, and service sensitivity. Meanwhile, through the comparative analysis of the three modes, we get the optimal threshold of each mode. Last, we conduct a case study comparing Chinese apparel and accessories brands Hodo and RUANS to verify the above relations. The results suggest that: (i) the more sensitive consumers are to live streaming stimulus, the more beneficial it is for the brand manufacturer to employ special live streaming, while the increase in unit service quality improvement cost will harm the brand manufacturer; (ii) the fixed participation fee determines the choice of e-commerce live streaming product showcasing modes; (iii) e-commerce live streaming product showcasing modes can help brands to optimize their decision-making.

我国航运上市企业财务杠杆与收益的负相关的面板数据计量回归分析

去杠杆、降风险成为近年来的经济热点问题。本文以A股上市的23家航运企业为研究对象,分析近年来航运企业财务杠杆与收益的关系。通过计量回归模型及stata软件分析发现:航运企业高财务杠杆并没有带来高收益,并且呈现出负相关关系,违背了一般经济规律。通过杜邦分析法,分析其产生的主要原因,并为航运企业合理负债提出对策建议。     

Costs and effectiveness of fingolimod versus alemtuzumab in the treatment of highly active relapsing-remitting multiple sclerosis in the UK: re-treatment,discount, and disutility

Objective: Patients with relapsing-remitting multiple sclerosis (RRMS) treated with disease modifying therapies (DMTs) who continue to experience disease activity may be considered for escalation therapies such as fingolimod, or may be considered for alemtuzumab. Previous economic modeling used Markov models; applying one alternative technique, discrete event simulation (DES) modeling, allows re-treatment and long-term adverse events (AEs) to be included in the analysis.

Methods: A DES was adapted to model relapse-triggered re-treatment with alemtuzumab and the effect of including ongoing quality-adjusted life year (QALY) decrements for AEs that extend beyond previous 1-year Markov cycles. As the price to the NHS of fingolimod in the UK is unknown, due to a confidential patient access scheme (PAS), a variety of possible discounts were tested. The interaction of re-treatment assumptions for alemtuzumab with the possible discounts for fingolimod was tested to determine which DMT resulted in lower lifetime costs. The lifetime QALY results were derived from modeled treatment effect and short- and long-term AEs.

Results: Most permutations of fingolimod PAS discount and alemtuzumab re-treatment rate resulted in fingolimod being less costly than alemtuzumab. As the percentage of patients who are re-treated with alemtuzumab due to experiencing a relapse approaches 100% of those who relapse whilst on treatment, the discount required for fingolimod to be less costly drops below 5%. Consideration of treatment effect alone found alemtuzumab generated 0.2 more QALYs/patient; the inclusion of AEs up to a duration of 1 year reduced this advantage to only 0.14 QALYs/patient. Modeling AEs with a lifetime QALY decrement found that both DMTs generated very similar QALYs with the difference only 0.04 QALYs/patient.

Conclusions: When the model captured alemtuzumab re-treatment and long-term AE decrements, it was found that fingolimod is cost-effective compared to alemtuzumab, assuming application of only a modest level of confidential PAS discount.     

我国高校科研“投入产出最小化”现象成因与对策研究

高校虽是我国三大科研主体之一,但其科研活动却广受诟病。在已有研究的基础上,深入分析我国高校科技成果转化率较低的主客观原因,发现高校科研系统存在着“投入产出最大化”悖论。基于“外部性”与“零和博弈”等经典理论,提出了“投入产出最小化”概念。根据“投入产出最小化”现象的本质和成因,从强化激励、加强监管、改善环境3个方面提出了系统性对策与建议。“投入产出最小化”现象的提出,为分析当前高校科研活动绩效提供了新的研究视角,对相关问题的进一步探讨具有借鉴意义。     

美日诺贝尔科学奖多获得性成因分析及对中国科研管理的启示

自2015年屠呦呦获得诺贝尔生理医学奖以来,国内引发了众多学者对于诺贝尔科学奖的极大关注。纵观诺贝尔科学奖100多年的颁发历程,美国无疑是获奖最多的国家,而日本则是亚洲获奖最多的国家。为此,分析了美国、日本诺贝尔科学奖多获得性的主要成因,并提出针对中国科研管理的一些引领性建议和可能性举措。     

地区知识产权形象形成机理研究——基于三螺旋模型理论视角

地区知识产权形象作为一个地区知识产权事业发展的立体缩影、综合评价和总体印象,涉及地区政治经济、科学技术和社会文化生活的方方面面,它通过地区各类主体与知识产权有关的种种行为来塑造,来影射。其中,地区政府、地区主导企业和地区社会公众,在地区知识产权的创造、保护、管理和运用的过程中,建立起一种相互联系、相互影响、相互作用的多重互反关系。这种多要素、非线性、动态博弈关系三螺旋关联作用模式,宜以三螺旋模型理论进行分析：当三者之间两两良性互动,三方交互重叠,构筑起积极、健康的地区知识产权形象;反之,任何一方的行为错位与缺失,并交互传导,引致连锁反应,久而久之,会形成一种消极、负面的地区知识产权形象。加强地区知识产权形象形成机理研究,既有利于我们积极建设、正确评价某一地区的知识产权形象,也有利于我们及时修正负面消极的地区知识产权形象。

Brand morphing across Wal-Mart customer segments

The premise of segmentation theory is that different segments each have a discrete customer profile and behavioral characteristics. At a conceptual level, the recent branding literature recognizes that different sub-cultures or segments could experience different meanings of an organization's brand. However, few quantitative studies address the issue. The current paper combines branding and segmentation theory and offers a new perspective on whether all segments have the same brand meaning. A leading discount retailer, Wal-Mart, is the focus of this Canadian-based investigation. Two segments of Wal-Mart customers are the basis of the study — one segment preferring Wal-Mart and one less attached. The research quantifies the two networks of brand meaning that the two segments associate with the Wal-Mart (corporate) brand. Empirically, brand morphing of the corporate brand occurs, with different brand meanings across the two segments.
