The Local Fiscal Expenditure and Economic Growth In The Chinese Transition Period

政府财政支出对于经济增长究竟产生怎样的影响一直有很大的争议，对各国政府财政支出政策效应的实际考察也众说纷纭。我国在过去20多年以政府为主导的自上而下的改革过程中，取得了巨大的成就。而地方政府的作用无疑是举足轻重的。伴随着经济体制的转型和公共财政体制的改革，地方政府财政支出规模和结构的变化对经济增长产生越来越重要的影响。因此，研究地方政府财政支出规模与结构对经济增长的影响，既具有重要的理论价值又具有重要的现实意义。 本文分六个部分来探讨地方政府财政支出规模与结构对经济增长的影响:第1章导论部分，主要包括研究背景、国内外文献综述、本文的研究内容与方法和本文的创新和不足;第2章为全文理论基础，分析...As for the affection of government public expentiture to economy growth,there are lots of controversy,and the opinions on effectiveness of government public expenditure are not coincided too.China obtained tremendous success by reform and opening policy in the past,and the Chinese local government played an important role undoubtedly.Alone with the economy system transform and public finance syste...学位：经济学硕士院系专业：经济学院经济研究所_政治经济学学号：2005130267

转型期地方政府投资行为与经济增长

在中国经济转型的过程中,地方政府具有相对独立的经济利益,成为推动我国经济快速增长的行为主体,其采取了许多措施扩大本地投资,促进经济增长。在"GDP竞赛"目标的推动下,地方政府不断地加大直接投资,由此带来的经济增长势必会使得资本在中国经济增长中的作用越来越显著。同时,这种增长是以减少整个社会的福利和降低资源配置效率为代价的。应该不断规范各级地方政府的投资行为:首先要进一步界定地方政府职能;其次应当加强硬预算约束;最后应当完善政绩考核机制

中国转型式制度冲击与宏观经济波动——基于改革开放30年数据的实证研究

本文就改革开放以来制度变革冲击对我国宏观经济波动的影响这一经验事实进行了研究。通过构建中国经济转型的制度变革指数,对我国宏观经济波动和转型式制度冲击波动的关联性和互动性进行了分析。分析发现,自我国经济转型以来,制度变革冲击对宏观经济波动的影响明显。转型制度冲击对宏观经济波动的影响周期更长,同时其冲击影响具有递减性;在各个转型变革中,非国有化冲击对宏观经济波动的贡献率最大;转型式制度冲击对宏观经济波动产生冲击需要一定的时滞,这符合制度变量对宏观经济影响的性质特征。2009教育部研究基地重大项目“转轨深化、经济结构调整与可持续发展”(2009JJD790039);教育部新世纪优秀人才支持计划项目的资金资助;2009国家社科基金一般项目“新中国60年经济发展与制度变迁的互动关系与经验教训研究”(09BJL002)

Influence of UV-irradiation on the Composition of Fatty Acids in the Vegetable Oil

采用酯化衍生-气相色谱/质谱法分析了5种市售植物油中的10种脂肪酸,脂肪酸总量在葵花籽油和玉米油中最高,在花生油和菜籽油中最低,橄榄油居中。组成分布特征以油酸和亚油酸占绝对优势（84.8%~94.7%）,但橄榄油中油酸和亚油酸的比值为1.0,显著高于其他油脂。500 W汞灯作光源,模拟光照24 h后,脂肪酸整体都呈现下降趋势,其中葵花籽油的下降幅度最大（50%）,而玉米油的下降幅度最小（30%）;随光照时间延长,油酸与亚油酸的比值呈逐渐升高的趋势,但反油酸与油酸的比值虽有所降低,但不同油脂之间差异较大。总体而言,光照可以降低植物油的营养价值成分,在贮藏和使用过程中,应尽量避光保存。A total of 10 fatty acids in 5 kinds of vegetable oil bought from local supermarket were analyzed using esterification-GC/MS.The highest concentrations of fatty acids were found in sunflower seed oil and maize oil,followed by olive oil,peanut oil and colza oil.The composition of fatty acids in vegetable oil was characterized by very high oleic acid and linoleic acid,accounting for 84.8%-94.7% of the total fatty acids.The ratio of oleic acid to linoleic acid was 1.0,which was much higher than those in other oils.A 500 W mercury lamp was used to produce UV light source and the irradiation period was set as 0,8,16 and 24 h,respectively.The highest loss of fatty acids was found in sunflower seed oil（around 50%） while the lowest loss was found in maize oil（around 30%）.The ratio of oleic acid to linoleic acid increased with irradiation time,while the ratio of trans oleic acid to oleic acid showed slight decrease trends and varied from oil to oil.In general,the vegetable oil needed to keep in dark place during the storage and in use in order guarantee the quality

EFFECT OF STRUCTURAL RELAXATION ON THE DEFORMATION BEHAVIOR OF A Zr64.13Cu15.75Ni10.12Al10 BULK METALLIC GLASS UNDER NANOINDENTATION

Structural relaxation by isothermal annealing below the glass transition temperature is conducted on a Zr64.13Cu15.75Ni10.12Al10 bulk metallic glass. The effect of structural relaxation on thermal and mechanical properties was investigated by differential scanning calorimetry and instrumented nanoindentation. The recovery of the enthalpy in the DSC curves indicates that thermally unstable defects were annihilated through structural relaxation. During nanoindentation, the structural relaxation did not have a significant influence on the serrated plastic flow behavior. However, Structural relaxation shows an obvious effect in increasing both the hardness and elastic modulus, which is attributed to the annihilation of thermally unstable defects that resulted from the relaxation

The method of characteristic lines to solve the stress wave equations is proposed considering the interactions of pile and soil.The optimization method can be used to quantitatively detect the faults in piles, where the soil parameters inversed from a model with complete pile are used to inverse the equivalent stress wave impedance for others with damaged piles and then identify their corresponding faults. Numerical examples of the simulation for experimental piles and of the detection for engineering piles show that the method gives the quite accurate results, especially for those with primary or secondary faults

THE ANALYSIS OF FLOOR RESPONSE SPECTRUM IN EQUIPMENT-STRUCTURE INTERACTION FORM IN FREQUENCY DOMAIN

直接从由建筑物和设备组成的主次结构耦合系统各自的动力特性出发,考虑主次结构间调谐、干扰、非经典阻尼等因素的影响,推导出频率传递函数和次结构的加速度均方根响应,并由此进一步得到楼层的加速度均方根反应谱。这一方法避免了求解联合系统的复特征值和动力方程出现病态等问题,大大简化了计算过程。最后在算例中就次结构的阻尼比、质量比、安装楼层及场地土等因素对楼层加速度均方根反应谱的影响进行了讨论,算例表明,质量比是决定能否采用古典谱的关键因素,场地土对反应谱的影响也不容忽视。Based on the dynamic properties of the primary-secondary coupling structural system composed of an equipment and a structure,the frequency transfer function and the root mean square of acceleration response of the equipment are deduced directly,and the factors including tuning,interaction and non-classical damping have been taken into consideration in the process of deduction.Furthermore,the floor response spectrum of the root mean square of acceleration is obtained.Since the calculation of the complex eigenvalue problem and the ill-conditioned equation of motion of the combined system are avoided in this approach,the procedure of calculation is simplified greatly.In the end,the influencing factors on the floor response spectrum are discussed,including damping ratio,mass ratio,the location of the equipment and the soil of the building site.As shown in the numerical example,the mass ratio is the key factor in deciding whether the classical floor response spectrum may be used or not,and the influence of the soil of the building site should not be ignored

规训之术:日据时期的台湾高山族教育

规训是一种特殊的权力技术,它塑造了个人。规训教育的目的是以规训为手段,生产出符合制度需求的个体。日据时期,日本当局为了巩固其在台湾的殖民统治,在高山族地区设立日语传习所、\"蕃人\"公学校及\"蕃童\"教育所等,试图通过教育手段向台湾高山族灌输日本国家意识,改变高山族固有的语言及风俗习惯,生产出\"驯服\"的肉体,以服务于其殖民统治。日本殖民者操纵规训之术的意图不仅是达成肉体的顺从,更是通过重新建构高山族身体以达成对人的意识形态的教化及塑造。依靠国家权力的输入,透过教育对台湾高山族进行殖民统治,日本殖民者企图实现\"同化\"之目的
