基于因子分析法的湖南省工业结构调整优化研究

湖南省工业结构呈现出产业结构比例的重型化、产业结构层次的低端化等特征。通过采用企业科技活动人员、当年科技活动经费支出总额、企业单位数、工业总产值等14个指标构建湖南省工业产业选择指标体系，运用因子分析法对湖南省工业结构的实证分析表明：科技创新能力、经济效益和产业规模是影响产业综合竞争力的主要因素，且湖南省大部分工业产业科技创新能力不强、投入产出效益有待提高、规模需要扩大、整体竞争力有待提升，需要有针对性地采取调整优化措施。     

Climate threshold,financial hoarding and economic growth

We use an iterative finite difference method to establish theoretical models that reflect the relationships among climate threshold, financial hoarding and economic growth. We build a simultaneous equations model to conduct an empirical analysis based on China’s statistical data from 1979 to 2012. Our study yields the following results: China’s climate threshold has shown a zigzag-shaped rising trend since 1979; the main reasons for the rapid expansion of financial hoarding were high savings rate, savings leakage, higher marginal efficiency of financial hoarding compared to capital efficiency or higher internal creativity of the financial sector; there were positive cumulative effects between financial hoarding and economic growth, which were significantly inhibited by climate threshold; the climate threshold had discrepant influences on different industries. To achieve a balanced economy, more money should be invested in the real sector to appropriately reduce the rate of savings leakage; the financial sector should move from scale expansion to service efficiency improvements to increase its marginal contribution to the economy and to enhance capital efficiency; the real sector should improve technological innovation and speed up the adaptive adjustment in climate-sensitive industries to move from economic growth to advanced development.     

探析吴越文化对江南民间宗教信仰的影响

吴越文化的生成与变迁,受地理环境、经济条件、政治形势、移民结构的规定和影响。吴越文化有着独特的区域特征,对江南民间宗教信仰产生深刻的影响。江南地区先秦以来传承不息的迷信鬼神文化传统奠定了江南民间宗教信仰的社会心理底蕴;吴越文化的开放性与包容性促使佛教、道教鬼神观念向民间鬼神信仰渗透,丰富了江南民间宗教信仰的内容;吴越文化的多元性特征促使多种民间宗教之间相互融合、相互渗透。     

Teaching the history of economic thought

The main purpose of this survey is to present the results of a questionnaire recently sent to historians of economic thought.

从重置到重生:居住性历史文化街区生活真实性的保护

在居住性历史文化街区的改造中,往往由于忽视对生活真实性的保护,造成保护和更新中的重置现象。从常见的全盘重置、功能重置、居民重置入手,对居住性历史文化街区保护和更新实践进行反思。提出,在居住性历史文化街区保护和更新中,风貌保护是生活真实性延续的基础,功能保全是生活真实性延续的载体,居民保有是生活真实性延续的主体,只有减少重置现象,街区才能真正获得重生。

上海市商业保险密度的影响因素的实证研究

本文根据上海市1980-2007年之间的历史数据,采用多元线性逐步回归方法,构建人口机械增长率、劳保福利费用比例、全市居民消费水平指数、食品在社会消费品零售总额中的比重等自变量与因变量商业保险密度之间的数学模型,并对模型进行统计分析.     

European‐Type Contingent Claims in an Incomplete Market with Constrained Wealth and Portfolio

This paper considers the problem of hedgeability and replicability of European‐type contingent claims in an incomplete market with the wealth and the portfolio possibly being constrained. For the case of no constraint, using the idea of a Four Step Scheme (Ma, Protter, and Yong 1994), we prove the replicability of a class of contingent claims (including European call and put options) without assuming ad hoc technical conditions. For the case with the wealth and portfolio being constrained, several positive and negative results concerning hedgeability and replicability are presented.     

幼儿自我保护能力的调查研究

本文采用结构访谈法,以3-6岁的120名幼儿为研究被试,探讨了幼儿自我保护能力的现状。结果表明,从总体上来看,幼儿自我保护能力良好,从各维度上来看,幼儿的游戏活动自护、意外防护能力较好,生活活动自护能力次之,心理自护能力较差,城乡差异和年级差异在某些维度上也是存在差异的;中班是进行幼儿自我保护教育的关键时期。
