全国社会保障基金的风格资产配置研究——基于经济周期视角

根据美林证券的投资时钟理论,结合我国宏观经济的月度指标,将我国宏观经济状态划分为四个阶段,同时将全国社会保障基金的投资细分为10个类别的风格资产,基于经济周期视角对这10类风格资产的收益率状况进行分析,结果表明：在复苏阶段,股票资产的收益率最高,并且不同风格股票在收益率方面的差异不大,表现出齐涨的态势;在过热阶段,不同风格股票在收益率方面表现出较大的差异,小盘股的收益率表现最好,尤其是小盘成长股的收益率最高;在滞胀阶段,最安全的资产应该是现金资产,倘若考虑到通货膨胀率的因素,其实际收益率甚至为负;在衰退阶段,债券类资产的表现最好。同时,基于不同策略的资产配置方案的累计收益率比较结果表明：不同经济周期下的资产配置方案可以显著提高资产组合收益率。     

关于知识工人的几点思考

知识工人是主要以脑力劳动支撑作业过程,通过对获取的信息加以综合处理,从而创造性地提出解决问题的方法,具有自主管理和持续学习能力的劳动者。做好对知识工人的管理工作,需要解决如何提高知识工人作业过程的生产效率和如何计量脑力作业等问题。     

城乡统筹视角下的农民工养老保险制度设计

在社会保障城乡统筹视角下设计农民工养老保险制度,要求农民工养老保险不仅要实现农民工群体内的统筹互济,而且要实现与城镇、农村养老保险的统筹对接.由于现实条件所限,一步实现农民工养老保险与城乡养老保险的统筹对接根本不可能做到,所以,城乡统筹视角下设计农民工养老保险只能根据农民工自身的特点和现实需要,因地制宜,逐步推进.     

论我国农村经济发展的金融支持

农村资本积累缓慢,存在着严重的供给不足,农村积累资金的一部分又通过其他途径流向城市,更加重了乡村资本的稀缺,阻碍了农村经济的发展.加快农村经济发展的根本途径,是向农村提供金融支持,政府应通过加大对农村公共品和农业基础设施的投入,改善农村投资环境,改革和完善农村金融体系,改革现有的农地制度,为农民、农村提供融资工具,以获取发展的资本来推动农村地区的经济发展.     

中国省际城镇职工工资收入分布演进的时空特征

运用Kernel密度估计方法和空间马尔科夫链分析方法,并将空间因素纳入分析框架中,对1978—2009年期间中国省际城镇职工工资收入分布演进的时空特征进行了分析。研究结果表明:从时间动态性看,中国省际城镇职工工资收入的差距正逐步固化和深化,多俱乐部收敛特征明显、贫困陷阱问题日益突出;从空间动态性看,近邻效应对省际城镇职工工资收入分布演进存在一定影响,多数省份的工资收入水平向邻区的平均工资收入水平演进。     

Drivers of customer decision to visit an environmentally responsible museum: merging the theory of planned behavior and norm activation theory

The main goal of this research was to merge the theory of planned behavior and the norm activation theory into one model and test its applicability in an environmentally responsible museum context. A filed survey was conducted at museums. Structural equation modeling was used to test research hypotheses. Results of the structural model comparisons revealed that the prediction power of our integrated model was superior to that of the theory of planned behavior and the norm activation theory. The proposed relationships among research constructs were generally supported. The mediating role of study variables was established. Additionally, the salient role of personal norm and attitude in generating museum travelers’ pro-environmental intention was identified. Overall, there was a strong support for the proposed theoretical model.     

Emerging youth tourism: fostering young travelers’ conservation intentions

Greening is one of the most important issues faced by the tourism industry today. Nevertheless, theoretical and empirical research on young travelers’ sustainable behaviors is scarce. This study developed a conceptual framework involving biospheric value, environmental concern, environmental awareness, ascribed responsibility, and moral norm in order to better explain young travelers’ pro-environmental decision-making process. A total of seven hypotheses were proposed and tested using structural equation modeling. Results revealed that the postulated theoretical model satisfactorily accounted for three dimensions of young tourists’ environmentally responsible intentions; the study variables are all significantly related; and the mediating impact of moral norm and environmental concern was evident. Moreover, the prominent role of moral norm in forming intentions was noteworthy. Our findings from the invariance test further indicated that environmental awareness and ascribed responsibility acted as moderators. The implications of these results are discussed.     

农民工与城市可持续发展

当今的农民工与历史上的“流民”不可同日而语,他们已经成为产业工人的重要组成部分,其廉价劳动力大大提升了城市竞争力。然而,农民工在为城市发展带来机遇的同时,也使城市面临着资源整合、社会融合及管理调适等方面的挑战。为应对这些机遇与挑战,城市政府需要转变管理理念,完善有关法规,不断创新农民工管理体制。进一步提高公共服务能力。
