基于OID编码体系的汽车电子标识编码应用研究

本文为了解决物联网所连接对象的多样性带来的标识体系存在不兼容、相互矛盾的问题，基于车联网RFID汽车电子标识的使用特点，创造性地提出将OID编码和汽车电子标识编码相结合的方案。首先简单介绍了基于发证机构及时间和基于汽车VIN码的两种OID编码规则；然后提出了OID编码在汽车电子标识芯片中的规划，主要是内存分配方案；最后介绍了相应区域的读写操作的具体方法。     

When Do Qualitative Risk Disclosures Backfire? The Effects of a Mismatch in Hedge Disclosure Formats on Investors' Judgments

Disclosure standards mandate the quantitative disclosure of hedging‐instrument‐related risks but not the disclosure of hedged‐item‐related risks. We examine how a match (mismatch) in formats, caused by making quantitative (qualitative) hedged item disclosures alongside quantitative hedging instrument disclosures, affects investors' integration of information from these two related disclosures. Our first experiment varies the hedged item disclosure format (quantitative or qualitative) and the portion of risk hedged (small or large). We find that when disclosure formats are mismatched, the less comparable nature of the two disclosures caused investors to neglect the offsetting relationship when assessing net risks. As a result, risk and investment judgments were influenced by the more prominent quantitative hedging instrument disclosures. Our second experiment finds that the use of a qualitative debiaser that clarifies the relationship between the two disclosures led to the integration of information and mitigated this effect.     

EMD-RBF组合模型在城市轨道交通客流预测中的应用

随着我国城市轨道交通路网的不断发展与完善,城市轨道交通客流预测作为城市轨道交通规划设计和运营管理的基本依据及城市轨道交通建设过程中的重要环节,其重要性也越来越明显。通过对城市轨道交通客流历史数据进行统计分析,针对平常日客流变化的非平稳性统计特征,构建EMD-RBF组合预测模型对城市轨道交通平常日客流进行预测。以北京地铁客流预测为例,得出利用IMF分量进行预测的EMD-RBF组合模型方案可以有效提高客流预测的精确度。     

产权流动是国有传媒机构改革的根本出路

产权流动是市场经济改革深化的重要形式之一,是按市场规律发展的必然趋势。通过国际视野的对照与案例分析可以看出,中国国有传媒机构的产权流动是一个急迫的现实问题,由于所有制的限制、行政干预过多等原因,国有传媒机构进行产权流动应将决策权、执行权和监督权分开而独立,探索国有传媒机构的产权改革,着力改变"发展惰性",进行有限创新,全面探索多元资本进入机制。     

基于银行理财顾客特征的产品模式创新研究

基于“感知利益”与“感知风险”权衡视角构建了银行理财顾客识别模型,将银行理财顾客划分为感知高利益—高风险敏感型顾客群体、感知低利益—高风险消极型顾客群体、感知低利益—低风险冷漠型顾客群体、感知高利益—低风险积极型顾客群体.应针对不同类型顾客群体的感知利益与感知风险对于购买意愿综合影响作用的差异、感知利益与感知风险构成维度重要程度的差异及人口统计特征和购买理财产品特征的差异,采取不同的提升感知利益且降低感知风险的创新产品模式.     

Gender Diversity in the Boardroom and Risk Management: A Case of R&D Investment

Increasing gender diversity in the boardroom has been promoted as a way to enhance corporate governance and risk management. This study empirically examines whether boards with more female directors play a role in reducing R&D risk. We first show that female directors help to reduce the positive relationship between R&D investment and future performance volatility. We then report that firms with more gender-diverse boards exhibit a lower adverse effect of R&D on the cost of debt. These results are robust to endogeneity analysis, alternative measures of gender diversity and risky investment, and other sensitivity tests. Overall, our results suggest that female directors improve board effectiveness in risk management with respect to R&D investment.     

Understanding Business Relationship Management in China： A Power and Leverage Perspective

This paper examines whether a power and leverage perspective, successfully applied to analyse extended buyer-supplier relationships in a western context, can be used to analyse business relationships in China. A single embedded case study is presented in this paper and a power and leverage approach is used to analyse business relationships. The power and leverage perspective is applicable for investigating buyer-supplier relationships in a Chinese cultural context. However, in this context using power as coercion is an extremely counterproductive relationship management strategy, which can draw both buyers and suppliers in to a ＂no-win＂ or negative sum situation. The findings are based upon a single case, which makes drawing generalisable conclusions more difficult. In addition, although every effort was made to limit the subjectivity of the power and relationship analysis, researcher interpretation of the data was required. In the Chinese business context, it may not be advisable to manage any relationships in an arms-length manner. Chinese business networks are centred on less explicit or formal power relationships and therefore companies that have learnt the rules of the game of exchange in the west need to modify their approach in China. This work extends the understanding of buyer-supplier relationships and provides additional empirical evidence validating a power and leverage perspective. In addition, the paper provides the first assessment of whether this approach can be used in a non-western context without significant modification.     

Driving force from authorities: the evolution of innovation system for biomedical industry in China

Over the past 30 years, China has fully exploited its advantage to steadily foster an innovation system for the biomedical industry with Chinese characteristics, that is, ‘Government-guided, resource-integrated and long-term planning.’ The system originated from historically famous ‘863 program’ in the 1980s, evolved with a series of favourable policies in the different periods, and eventually has taken shape in the industrial clusters across the country. It features with a systematic and integrated R&D infrastructure (or public platform) at different levels. In this study, China’s biomedical innovation system will be examined and the leading role of Chinese authorities will be explored from the perspective of Triple Helix theory. As the ‘highland of innovation’, Shanghai case is highlighted with plentiful information gathered from primary sources in the involved agencies for the first time, including the Shanghai Biopharma Service Platform.
