基于仓储企业功能的仓单质押业务改进研究

仓单质押既是一种新的物流业务,也是一种金融产品。由于它能够解决中小企业融资难的问题,又能给仓储企业和银行带来新的利润增长点,因此在国内得到了迅速发展。但由于此业务在国内开展时间较短,相关政策、法规不健全,也出现了很多问题。本文试图从仓储企业的角度,为如何解决我国仓单质押业务中的问题提供概括的思路和见解。     

中国专利对经济增长方式影响的实证研究:1988～2008年

运用我国1988~2008年省级面板数据,以全要素生产率体现经济增长方式,考察不同类型专利对经济增长方式的影响,结果凸显以1997年为断点的阶段性差异。实证结果显示,发明专利在1997年前对全要素生产率没有显著影响,但在1998~2008年对全要素生产率的影响远大于实用新型和外观设计专利,论证了原创型创新对现阶段我国经济增长方式转变的重要性,这与现有研究的结论不同。     

The Shapley Value of a Patent Licensing Game: the Asymptotic Equivalence to Non-cooperative Results

We consider a game in characteristic form played by firms and an outside patent holder of a cost-reducing innovation. The worth of a coalition of players is the total Cournot profit the coalition can guarantee to obtain when it operates an optimal number of its firms while the complement operates any number of its firms as to minimize the profit of the coalition. Only firms in a coalition with the patent holder are allowed to use the efficient technology. We prove that when the number of firms is large, the Shapley value of the patent holder approximates the payoff he obtains in the non-cooperative auction game traditionally studied in the literature.We thank an anonymous referee for very helpful comments that significantly improved the paper.

Evaluating the cost-effectiveness of percutaneous closure of a patent foramen ovale versus medical management in patients with a cryptogenic stroke: from the UK payer perspective

Aims: Percutaneous closure of a patent foramen ovale (PFO) is known to lower the risk of recurrent stroke in patients with a cryptogenic stroke. However, the economic implications of transcatheter PFO closure are less well known. From a UK payer perspective, a detailed economic appraisal of PFO closure was performed for prevention of recurrent ischemic stroke in patients with a PFO who had experienced a cryptogenic stroke.

Materials and methods: A Markov cohort model was constructed using a 5-year time-horizon with a patient mean age of 45.2 years, reflecting the characteristics reported in the REDUCE trial. Transition probabilities, clinical inputs, costs, and utility values were ascertained from published and national costing sources. Total costs, incremental costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios were calculated, utilizing a discount rate of 3.5%. A range of univariate and probabilistic sensitivity analyses were also performed.

Results: When applying a willingness-to-pay (WTP) threshold of £20,000/QALY in accordance with NICE guidelines, PFO closure compared with antiplatelet therapy alone showed a beneficial cost/QALY of £18,584, attained at 4 years. Applying discount rates of 0% and 6% had a negligible effect on the base-case model findings. PFO closure demonstrated a 76.9% probability of being cost-effective at a WTP threshold of £20,000/QALY at a 5-year time-horizon.

Limitations: This model focused specifically on UK stroke patients and typically enrolled young (mean age <65 years old) patients. Hence, caution should be taken when comparing data vs non-UK populations, and it remains unclear how older patients might have affected cost-effectiveness findings, as the risk of paradoxical embolism can persist as patients age.

Conclusion: Percutaneous closure of a PFO is cost-effective compared with antiplatelet therapy alone, underlining the economic benefits potentially afforded by this treatment in selected patients.     

WTO与中国企业专利发展战略

WTO以贸易为中心,在全球范围内将货物贸易、服务贸易与知识产权紧密地联系在一起,从而实现了专利保护全球化,知识经济时代知识产权成为了企业生存发展的核心问题,企业的生产、经营、管理都必须以知识产权为中心进行战略定位。专利是市场经济下的一种合法垄断,专利就是市场,要积极发挥专利技术的市场效用。加入WTO以后,中国市场成为了全球市场,中国企业必须立足发展中国家的现实,积极进行战略布局,才能在与跨国公司的竞争中生存和发展。专利战略已成为中国企业实施可持续发展的战略选择,成为了中国企业开展市场竞争的战略重点,也是中国企业进行对外贸易的战略举措。

保证金制度下C2C逆向物流平台定价研究

基于双边市场理论,引入保证金制度,建立5种定价模型,为C2C逆向物流平台选择均衡定价决策提供参考。研究发现,双寡头竞争市场中任一平台不会率先收取保证金,保证金的收取有可能使得平台对用户收取的注册费为负,并且5种定价模式中,大部分情况下平台选择对卖家收取保证金、对买家收取注册费时平台获取的利润最大。

基于图像识别的自有仓储存货质押融资业务模式

针对传统存货质押融资业务存在着道德风险高、信息透明度低以及融资成本较高等问题,提出了基于图像识别技术的利用第三方物流监管和自有仓储设施的存货质押融资业务模式,并详细设计了业务流程、说明各参与方职责;为了利用图像识别技术控制货物变动,初步设计了监控系统和图像识别方法;然后对新业务模式的成本和技术可行性进行分析,最后对比传统业务模式对其风险、成本优劣势进行分析,新业务模式可以推动存货质押融资业务发展。     

专利池重复联盟能否减少合作伙伴间专利诉讼

专利池内企业存在合作竞争现象,专利池重复联盟能否减少合作伙伴之间的专利诉讼？基于合作竞争理论,引入联盟学习观点,分析专利池内企业之间专利诉讼的影响机理,并以MPEGLA公司12个专利池内64家企业数据作为样本,运用负二项回归模型实证检验专利池重复联盟次数、探索式合作水平、联盟学习强度对池内成员企业之间专利诉讼的影响。结果发现：探索式合作水平提高,降低了企业对池内其它企业专利诉讼强度;重复联盟次数越多、联盟学习强度越大,企业对池内其它企业发起专利诉讼的行为就越严重。研究结论在理论上可为专利池提供新的分析视角,在实践上可为企业实施专利联盟战略、有效运用并防范专利诉讼提供重要参考与借鉴。
