基于云重心Shapley值的供应链融资联盟收益分配研究

针对Shapley值法在供应链融资联盟收益分配过程中分配因素考虑不全以及各分配因素随机性和模糊性强的缺点，本文利用云重心法修正Shapley值的收益分配。根据供应链融资联盟收益分配的主要影响因素，在传统的Shapley值法的基础上引入了风险系数、投入成本、努力程度以及信息对称水平4个分配修正因子，弥补了影响因素的缺失，并利用云重心法计算各联盟企业的收益修正值，云重心法能够解决定性指标和定量指标之间的模糊性转换，极大克服了Shapley值法自身的局限性。算例对比结果发现，改进的Shapley值法能更加合理的分配收益，有利于维持供应链融资联盟的稳定。     

民营资本的进入对我国风电产业发展的影响——基于断点回归的分析

为克服单差法存在变量内生性，倍差法对于控制组的严格要求往往无法得到满足，故文中采用断点回归的分析方法，在无对照组的情形下，对我国风电产业2012~2015年的资产总计、主营业务收入以及发明专利数月度数据进行实证研究，探究民营资本的进入对我国风电产业的影响。实证结果表明，从短期看，民营资本的进入对我国风电产业规模与技术效率具有统计上的显著正面作用，具有一定的经济意义；另外，这一机制的推行对产业创新产生了显著的负面作用。     

Urban air pollution in China: destination image and risk perceptions

Inbound tourist arrivals into China have been declining in recent years, possibly in response to increasing levels of urban air pollution. To examine Westerners’ contemporary views on China as a travel destination, with a particular focus on air pollution, this research surveyed 600 US and Australian residents. An online panel survey collected data on cognitive and affective destination image, cognitive and affective risk perceptions, intention to visit China and key demographic variables. The findings show that, while China's cognitive image attributes were perceived positively, potential travellers expressed negative views about travel risks in China in general and about air quality in particular. Importantly, feelings towards the risk of air quality had a significant negative impact on destination image as well as intention to visit China. The research contributes to theory by highlighting the importance of considering affective risk perceptions in destination image studies. While some market segments seemed less sensitive to air pollution than others, this paper concludes that unless China proactively addresses the problem of air pollution, for example by seeking to stimulate positive feelings, international arrivals may continue to be compromised.     

Keiretsu centrality — profits and profit stability: A power dependence perspective

Prior studies compare keiretsu member firm and independent firm performance. Here, we use historical and power dependence perspectives to theorize that the Japanese keiretsu system primarily benefits the most central firms. We test this by examining the performance of two types of keiretsu firms (central firms and other member firms) within two types of keiretsu (horizontal and vertical). We hypothesize and find that: (1) central vertical keiretsu firms are more profitable than central horizontal keiretsu firms; (2) central horizontal keiretsu firms have greater profit stability than central vertical keiretsu firms; (3) central vertical keiretsu firms are more profitable than non-central vertical keiretsu firms; and (4) central horizontal keiretsu firms have greater profit stability than non-central horizontal keiretsu firms. Implications for managers and future research directions are discussed.     

产权管制放松博弈与中国农业生产危机——基于结构突变面板数据模型的实证分析

基于产权管制放松的分析视角，本文构建一个政治风险下农民和国家的动态博弈模型来解释中国两次农业生产危机。此外，本文利用1959—1961年与1970—1977年两次中国农业生产危机的省级面板数据对理论模型进行了实证检验。结构突变面板计量结果表明，国家不会主动削弱自己的谈判能力，除非政策失误或外部竞争压力造成的冲击才可能迫使它在产权管制放松的博弈谈判中让步。

G20《消除数据差异提案》及对我国的启示

2008年国际金融危机的爆发,揭示出全球系统重要性金融机构之间存在着巨大的信息差异,欧美等国充分意识到一套全面及时的数据统计标准对于经济金融市场稳定的重要性。有鉴于此,G20于2009年发布了《消除数据差异提案》（Data Gaps Initiative）,在提案中提出了统一整合全球经济金融数据统计方式的20条建议。2013年G20峰会上,各国财长和央行行长一致表示要继续推动《消除数据差异提案》的实施,该提案预计将在2015年底被完全实现。本文对该提案出台的背景、主要内容和最新进展进行了梳理和分析,总结出对我国的影响与借鉴意义：有助于更好地实现我国宏观审慎政策目标;有助于促进我国数据统计标准化的发展;有助于提升我国宏观经济和金融稳定分析的水平。
