An Empirical Analysis of the Contribution of Fiscal Expenditure to the Economic Growth

由于受国际金融危机的影响,各国政府都在不同程度上扩大了其支出水平,推动经济的发展与复苏。文章首先建立政府支出对经济增长贡献率关系的理论模型,然后基于我国的相关数据,运用联立方程组模型,进行实证分析。实证结果表明,政府支出对经济增长不仅有直接的拉动作用,而且还会通过消费、投资的促进作用间接地拉动经济增长,同时还对政府支出对经济增长的贡献率进行了估计。Due to the international financial crisis,each governments try to expand its expenditure level to promote economic development and recovery.In this paper,the author builds up a theortical model of the contribution of fiscal expenditure to the economic growth,and model conclusions are tested by using simultaneous-equation model based on the data of our country.And then the research reveals that fiscal expenditure not only has a direct role in stimulating the economic growth,but also has an indirect role in promoting economic growth through the consumption and investment,meanwhile,the contribution rate of the fiscal expenditure to economic growth has been estimated

利用表面增强拉曼光谱快速鉴别卷烟生产中烟用香精香料

烟用香精香料的配方是卷烟工业中的核心技术,也是构建不同特色卷烟产品的关键之一。然而,现有的香精香料质量评价手段主要是人工嗅香和测定某些特定的物性指标,如折光指数、相对密度、酸值、挥发份总量等。在实验室科研中还有使用色谱-质谱联用等方法。但是上述手段仍存在较多问题,比如受主观意识影响,操作繁琐,前处理耗时长,费用高,灵敏度低等。基于此,本文开发了一种利用表面增强拉曼光谱技术结合主成分分析算法来快速鉴别实际生产中不同种类、不同掺兑样的烟用香精香料的方法。本文利用该方法成功获取不同种类、同一种类不同生产批次及烟用香精香料不同掺兑量样品的增强拉曼谱图。经主成分分析表明不同种类以及不同掺兑量样品的散点分布在不同区域,直接区分度高;同一种类不同生产批次的香精香料谱图类似,在散点图中较为集中;说明不同生产批次的样品以及不同掺兑量的样品都可以与其他种类的香精香料标准样品进行有效区分。本文利用表面增强拉曼光谱结合主成分分析算法对烟用香精香料进行检测的方法操作简易,检测快捷,成本低廉,结果便于分析识别,适用于烟用香精香料实际生产中的质量控制。国家自然科学基金(No.21522508)浙江中烟工业有限责任公司科技项目(No.ZJZY2016C002

A Journey into the City. Migrant Workers' Relation with the Urban Space and Struggle for Existence in Xu Zechen's Early Jingpiao Fiction

In contemporary China, rural-urban migrants constitute a new urban subject with entirely new identity-related issues. This study aims at demonstrating how literature can be a valid field in investigating such evolving subjectivities, through an analysis of Xu Zechen’s early novellas depicting migrants’ vicissitudes in Beijing. Combining a close reading of the texts and a review of the main social problems characterising rural-urban migration in China, this paper focuses on the representation of the identity crisis within the migrant self in Xu’s stories, taking into account the network of meanings employed by the writer to signify the objective and subjective tension between the city and the countryside

On the Relationship Between Disabled College Students' Resilience and Post-Traumatic Growth

为探讨残疾大学生心理弹性与创伤后成长的关系,以滨州医学院特殊教育学院106名残疾大学生为被试,运用心理弹性量表(CD-RISC)、创伤后成长调查量表(PTGI)进行调查.结果发现:(1)残疾大学生心理弹性总均分处于中上水平,单因素分析显示,不同性别、致残时间、生源地、有无手术经历、缺陷类型对心理弹性水平的影响有显著性差异;(2)除生源地两因素外,其他人口学变量对创伤后成长有显著影响;(3) Pearson相关分析显示,心理弹性与创伤后成长显著正相关,进一步回归分析,只有坚韧性和自强性进入回归方程.由此可以得出结论:(1)残疾大学生心理弹性与创伤后成长水平较好,性别、致残时间、生源地、有无手术经历和缺陷类型可能影响其心理弹性与创伤后成长水平;(2)心理弹性中的坚韧性与自强性可预测创伤后成长

Theoretical Research on Social Capital and Technological Innovation:Based on Enterprise's Perspective

社会资本对宏观经济发展和增长的影响是多层次、多角度的,它可以通过人力资本存量的提升、金融部门的发展以及企业技术革新等方面来刺激宏观经济又好又快的发展。然而,本文尝试从中微观角度出发,以相关的实证研究结果作为基础和前提条件,构建社会资本与企业技术创新的理论模型,并对其进行探讨和分析。但是,有关二者关系的实证性研究还有待于进一步的分析和探讨。Abstract:It is worth noting that the effect and impact of social capital on the development and growth of macroeconomic is multi-layered and multi-angle,that is,it can raise the stock of human capital,affect financial sector development and facilitate enterprise technology and innovation to stimulate economic fast and good development.However,this paper attempts to build a theoretical model of social capital with technological innovation based on microscopic point and the results of several empirical studies,then explore and analyze the relationship between this two.However,the empirical analysis between the social capital and enterprise technological innovation also requires us to make further study and discussion
