上海股票市场波动实证性研究:2001--从交易方式角度透视

我国股票市场上的交易方式有两种,即集合竞价和连续竞价,交易方式的差异会对股价的波动性产生影响,而市场的波动性对股票市场而言是双刃剑,因此从交易方式角度探求股市的适度波动成为理论工作的一个重心.本文以上海股票市场为研究对象,针对2001年的全部交易数据进行实证研究.结果表明,集合竞价形成的开盘价格收益率的方差大于连续竞价形成的收盘价格收益率的方差,其原因在于集合竞价与连续竞价相比,其交易过程的透明度差和交易指令具有不可更改性,据此,从交易制度上提出政策建议.

欧盟的国际行为体权力结构分析

一个国际行为体可以运用军事力量、经济力量、国际制度和价值规范四种资源,通过强制、威胁、奖赏、设置议程、说服和吸引等六种方式来对其他行为体施加影响和控制。在这一过程中,它具有了多种权力,从而形成一定权力结构。随着欧盟国际行为能力的增强,欧盟具有了经济权力、军事权力、规范性权力和制度性权力等四类国际行为体权力,形成了四维度不均衡的权力结构。在考察欧盟国际行为体权力结构时,制度性权力这一维度不可忽视。     

投资组合的行业集中度与基金业绩研究

本文探讨了投资组合的行业集中度与基金业绩之间的关系。采用Kacperczyk等的方法测量各基金的投资组合在13个行业中的资产配置情况,我们发现基金投资组合的行业集中度与基金业绩之间存在显著的负向关系,这说明行业集中度更高的基金业绩落后于那些实行分散化投资的基金。最后,不同子样本期间的考察表明结论是稳健的。因此,我们建议基金经理人在执行更为集中的行业投资策略时,应该保持谨慎的态度。     

全球化时代发展中国家与跨国企业的角力

全球化是国际关系研究中的重要现象,跨国企业则是全球化现象的重要媒介和载体。直至上世纪80年代初,跨国企业仍被大部分发展中国家的政府视为发达国家经济侵略发展中国家的工具。现在政府对跨国企业的友善态度,可以说是服从于全球化进程中的世界经济深刻转变局面下所出现的逻辑变化。这些相关过程充分改变了跨国企业与发展中国家的关系,双方不断调整本身的方针及策略,争取与全球新形势下的现实接轨。本文尝试回顾及检视跨国企业与发展中国家两者关系中出现的转变,并进而指出考虑跨国企业的问题时,需要将有关研究视角放置于全球经济整体增长的背景当中。在全球化时代,发展中国家及跨国企业应视双方之间的关系为一种互补的关系,这种互补性有助国家提升资源运用及相关素质能力。发展中国家只有正确认识及合理利用跨国企业,才能积极推动政治建设和社会经济的持续发展。

Transnational queer sociological analysis of sexual identity and civic‐political activism in Hong Kong,Taiwan and mainland China

The sociology of homosexuality lacks engagement with queer theory and postcolonialism and focuses primarily on the global metropoles, thus failing to provide a plausible account of non‐Western non‐normative sexual identities. This research adopts the author’s newly proposed transnational queer sociology to address these deficiencies. First, it critiques the Western model of sexual identity predominantly employed to elucidate non‐Western, non‐normative sexualities. It does so by examining not only the queer flows between West and non‐West but also those among and within non‐Western contexts to produce translocally shared and mutually referenced experiences. Second, the proposed approach combines sociology with queer theory by emphasizing the significant role of material, as well as discursive, analyses in shaping queer identities, desires and practices. This article employs the approach to examine young gay male identities, as revealed in 90 in‐depth interviews conducted in Hong Kong (n = 30), Taiwan (Taipei, n = 30) and mainland China (Shanghai, n = 30) between 2017 and 2019. More specifically, it highlights the interplay between the state and identity by investigating the intersection and intertwining effects of these young men’s sexual and cultural/national identities, revealing three different forms of civic‐political activism. The article both demonstrates the way in which sexuality and the state are mutually constituted and provides nuanced analysis of the heterogeneity of contemporary homosexualities in Hong Kong, Taiwan and mainland China. In applying a new sociological approach to understanding sexuality, this research joins the growing body of scholarship within sociology that is decentring the Western formation of universal knowledge.     

Finding the vulnerable among China’s elderly: identifying measures for effective policy targeting

Facing a rapidly aging population, China has recently started to formulate and implement policies with the aim to provide old-age care. While well-developed old-age care policies commonly include a built-in component that assesses eligibility based on vulnerability, no such process is established in the context of China. Here, based on data from the China Health and Retirement Longitudinal Study collected in both 2011 and 2013, we (a) developed a simple and effective strategy for identifying vulnerable Chinese elderly, which can serve as a basis for policy targeting, and (b) improved the policy relevance and targeting efficiency of this vulnerability measure by including additional health indicators. Our vulnerability measures identify 35% to 46% of Chinese elderly as vulnerable, covering up to 67% of elderly at high risk of death or functional decline. They can serve as an initial screening step for more comprehensive geriatric assessments and enable policy makers to effectively target vulnerable elderly persons in China.
