Growth, welfare and transitional dynamics in an endogenously growing economy with abatement labor

This paper sets up a simple endogenous growth model that highlights the importance of the endogenous labor-leisure choice and the allocation between production labor and abatement labor. We show that, in contrast to the common notion (e.g. [Bovenberg, A.L., Smulders, S., 1996. Transitional impacts of environmental policy in an endogenous growth model. International Economic Review 37, 861–893] and [Bovenberg, A.L., de Mooij, R.A., 1997. Environmental tax reform and endogenous growth. Journal of Public Economics 63, 207–237]), the existence of an environmental production externality is a sufficient (but not necessary) condition for environmental policies to stimulate economic growth if the labor-leisure choice is endogenously determined. In particular, since there are complementarities between public abatement and private abatement, the public abatement expenditure will have a more powerful enhancing effect on economic growth when it is accompanied by more efficient private abatement. This result also leads to a corollary to the effect that it is easier to achieve double dividends in terms of enhancing both growth and welfare if the endogenous labor-leisure choice is taken into account.In our dynamic analysis, we show that if public abatement is substantially large, dynamic indeterminacy may occur despite the absence of a positive labor externality and interestingly, this is more likely to be the case when abatement labor plays a more significant role. Besides, the transitional effects of an increase in public abatement are also investigated.     

消费者在进口跨境电商平台间转移行为意向研究

本文整合人口学推拉理论和技术接受模型,从推送力、拉动力、锚定力三个方面构建理论模型和提出假设,收集数据验证消费者在进口跨境 电商平台间的转移行为影响因素。研究结果表明,经济性因素、平台服务质量是影响消费者向新平台转移的推送力,感知有用性和感知易用性是新平台 吸引消费者转移的拉动力,转换成本和消费者习惯是阻碍消费者转移的锚定力。对此,企业可通过提高用户体验、增加转移成本防止消费者流失。     

社会主义与统一多民族国家的国家建设(1947-1965)

在民族区域自治制度的奠基过程中,通过社会主义宗旨所要求的贯彻群众路线、培养少数民族干部,成功促进了中央政府和各族人民群众的直接沟通;通过让各族人民群众翻身当家做主、改善民生福祉等社会主义性质的政治举措,形塑起各族人民群众对党和国家发自内心的认同;通过民族平等之制度前提、社会主义经济制度等制度性组织模式,以及相关具体实践途径,实现了中国各族人民大团结;在社会主义国家单一制、人民共和、中国共产党领导的制度基础之上,民族区域自治成功地将国家内部的不同民族凝聚成为具备有机整体结构的中国人民,呈现为一种促进沟通、赢得认同、实现团结、巩固统一的统一多民族国家的国家建设过程。因此,民族区域自治成功实现清末以来统一多民族国家之国家建设质的飞跃的制度要义,恰在于社会主义这一国家根本制度。     

Critical factors associated with relationship conflicts and group atmosphere among Taiwanese adolescents

This paper investigates relationship conflict amongst Taiwanese adolescents. The data was taken on Taiwanese adolescents aged 15–17 who attended 16 high schools which are located in north, middle, south, and the east of Taiwan. They were invited to participate in the study during the 2010 school year. This paper explores the patterns among relationship conflict including its impact, the social dimensions, the time aspects, the psychological implications, the physical dimensions, and the performance and overall risks involved in group atmospheres. The ways relationship conflict handling styles correlate with the group atmosphere were also explored. Each one of the risk variables’ correlations and relationship conflict were explored. As part of this study upon correlating each one of the risk variables and relationship conflict, the researchers studied the correlations between the risk variables and the group atmosphere.     

应用ANSYS建立再生混凝土随机骨料模型的方法研究

通过对再生混凝土粗骨料成份的分析,初步提出将再生粗骨料大致分为以附着砂浆石子为主要成分并含有少量砂浆块和砖块杂质,并确定某批次再生粗骨料中各类骨料的百分含量。应用ANSYS的APDL参数化编程,结合蒙特卡罗方法和富勒级配理论,从细观层次上生成再生混凝土各类骨料的二维圆形与三维球形随机骨料模型,并赋予各类骨料的材料属性。然后根据选定的单元类型进行有限元网格的划分,通过判断各单元与骨料形心的位置关系来识别砂浆基质与骨料之间的界面单元,并赋予它相应的材料属性。从而建立起再生混凝土的数值模拟试件,为今后在ANSYS中直接对其进行加载求解,以此来模拟各种力学性能试验提供了必要的基础。     

变频器在使用过程中的故障及防范措施

交流变频调速技术是20世纪80年代兴起的一种新型技术。它具有调速方便,保护功能完善,组态灵活,可靠性强,节能降耗等特点。当前变频器在工业控制中被广泛应用,成为工控系统中的重要的部件,但在实际使用中由于安装环境和使用方法的差异,不可避免的会出现一些问题。本文就变频器在使用中的一些突出问题及解决办法进行论述。

浅论两汉时期河湟羌人的种姓家支制度

两汉时期的羌乱给汉王朝带来了巨大的灾祸,是促使东汉灭亡的因素之一。除了共同的政治经济利益使河湟各羌落凝聚起来反对汉王朝对羌民的歧视和苛政外,其本身存在已久的种姓家支制度亦使河湟羌落间始终有种潜在的联系,也正是这种制度使得徙入塞内上百年的羌人仍与塞外的羌落间有着相同的认知,促进羌落间的聚合。因此种姓家支制度是种潜在的凝聚机制。汉王朝亦认识到羌人家支制度对其统治产生的威胁,也有意识的予以破坏。

A MCGP decision aid for homebuyers to make the best choice

This study adopts a new approach, the multi-choice goal programming (MCGP), to evaluate houses in order to help homebuyers to find better house based on the residential preferences. According to the function of MCGP, homebuyers can set multiple housing goals with multiple aspiration levels. This increases the flexibility to find a suitable house. Compared with other classical methods such as checklist and analytic hierarchy process, MCGP is more efficient, especially while considering a lot of housing criteria and house alternatives. In order to demonstrate the usefulness of MCGP decision aid for housing selection, a real case study is then provided. Furthermore, ten volunteers are invited to participate in the empirical experiment. The results also validate the effectiveness and efficiency of MCGP decision aid.
