中国城市流动人口影响因素的定量研究

利用公安部 1996年流动人口统计数据和国家统计局 1996年国民经济和社会发展统计数据 ,对中国城市流动人口的影响因素进行研究发现 :(1)城市流动人口规模与市区从业人口、市区个体劳动者人数、市区国内生产总值、市区工业总产值、市区利税总额、市区固定资产投资总额、市区社会消费品零售总额、市区实际利用外资金额和市区职工年平均工资相关显著 ;与市区人口、市区非农业人口、市区第二产业从业人员比重、市区第三产业从业人员比重、市区百元资金实现利税和市区客运总量相关不显著 ;与地区人口呈负相关。 (2 )流动人口超过 5 0万以上的城市 ,其流动人口规模与市区的社会经济因素回归效果较好 ,回归方程可以用于预测     

关联方增信与资产证券化信用风险溢价——基于底层资产风险的统计分析

本文着眼于企业资产支持证券(ABS)市场的信用风险溢价,探讨关联方增信的效果。研究表明,采用关联方增信的ABS风险溢价较高;当同一主体先前发行的ABS评级上调时,新发行ABS的风险溢价会因为采用关联方增信而升高。本文进一步探究了产生上述现象的原因,一方面,关联方增信使得集团内部风险集聚;另一方面,企业的道德风险使得原ABS的评级上调成为反映新ABS底层资产质量变差的负面信号,从而影响投资者的定价判断。本研究揭示了关联方增信可能存在的道德风险问题。通过分析ABS丰富的底层资产统计特征,本文发现集团风险集聚导致ABS的底层资产质量下降,进而提高了企业的融资成本。本文建议监管机构可以通过适当限制关联方增信或加强监管的方式保障我国企业资产证券化市场的健康持续发展。     

DEFINING MOMENTS: THE TENSION BETWEEN RICHNESS AND REACH

The defining moments of traditional spatially based higher education are made up of fixed and fluid experiences. These 'moments' are now creaking as funding per student falls and the romanticized ideal of an education detached from 'real' life falters under the weight of highly variable student experiences. Distance learning in all its guises has always been regarded as inferior by those embedded in the traditional system. However more and more students demand something different from costly campus-based education. It is time for a more open discussion about the tensions between richness and reach and the role that new facilities like the Internet could play in reaching more students without wallowing in the nostalgia that often accompanies such debates.

Intra-industry diversification effects under firm-specific contingencies on the demand side

How do firm-specific, demand-related factors influence the relationship between intra-industry diversification (IID) and performance? Recent findings regarding the performance effects of IID depict a complex picture with curvilinear relationships and several contingencies. However, firm-specific contingencies on the demand side have remained unexplored. We analyze how IID relates to firm performance (market share) in the German automotive industry using panel data between 1999 and 2008. We specifically focus on a firm's high-quality brand image as a demand-side contingency. We find support for our hypotheses of complex curvilinear relationships as well as for moderating effects of brand quality. Our results have significant theoretical implications for the IID literature.     

企业技术效率的影响分析

 本文以上海市166家大中型企业五年的面板数据为研究对象,设定两种不同的生产函数和两种误差分布,利用随机前沿方法分别进行了技术效率的估计。我们发现不同测算方法的结果差异不大,且对企业的评价具有一致性。结果表明上海市工业企业的技术效率整体水平不高。通过研究影响企业技术效率的外生性因素,发现企业的所有制结构、规模、R&D经费支出与R&D人员投入、资本密集程度和企业的垄断程度等因素都对上海市工业企业的技术效率水平具有显著影响。基于研究结果,我们给出了提高企业技术效率的一些建议。     

中国农村大龄未婚男性安全性行为倾向的影响因素：基于计划行为理论的研究

本文基于计划行为理论,研究了受到婚姻挤压的农村大龄未婚男性安全套使用倾向的心理因素和社会人口统计因素。数据来源于2008年8月-9月西安交通大学人口与发展研究所在安徽JC区开展的＂农村大龄男性生殖健康和家庭生活调查＂。Logistic回归分析结果显示,积极的互动态度、较高的性伴规范,较高的知觉行为控制和首次性行为中使用了安全套的经历与大龄未婚男性安全套使用倾向显著正相关。此外,较小年龄组的未婚男性更倾向于使用安全套。本研究结果有助于我们更好地理解农村大龄未婚男性安全套使用机制,能为促进农村地区安全性行为的干预项目提供理论借鉴和支持。     

流动女性的婚姻质量及其影响因素

文章利用＂流动人口的婚姻家庭调查研究＂课题收集的数据,对流动女性的婚姻质量现状进行描述。在对中外关于流动人口和婚姻质量进行文献回顾的基础上,提出影响流动女性婚姻质量因素的假设,进而对实证资料进行回归分析,结果表明个人条件、流动经历、物质条件以及婚育状况等都是流动女性婚姻质量的影响因素。     

Psychosocial work environment and mental health among travelling salespeople

Travelling salespeople have a rather unusual working environment, with long periods of absence from their firm and a low level of social contacts with colleagues. Furthermore, they are exposed to high demands in their work, which may conflict with a normal family life. In this paper a cross-sectional study of psychosocial work environment and mental health of Danish travelling salespeople is described. A sample of 1,306 travelling salespeople filled in a questionnaire (response rate 68%). The results indicate that poor mental health is associated with a number of demand indicators: number of working hours per week, number of customers per week, non-day work, and a high level of perceived job demands. On the other hand, the number of hours spent with customers per week is positively associated with mental health. The authors did not find the expected associations between poor mental health and several factors such as number of hours away from firm, nights away from home, and a low degree of perceived support from colleagues and superiors. It is concluded that the main stressors of travelling salespeople are long working hours, many customers, non-day work and high perceived psychological demands in general.
