具缺货期不同决策支配权的两级供应链合作机制研究

从考虑市场需求固定且卖方和买方对缺货期的不同决策支配权情况,研究了两级供应链的合作机制,建立了其不完全信息的动态博弈模型,并得出其精炼贝叶斯纳什均衡,从理论上证明了卖方和买方分别占支配地位和从属地位时买方卖方应相互合作。     

关天经济区新型城镇化水平综合评价——基于PCA分析法

首先在界定了新型城镇化内涵的基础上,从新型城镇化发展的动力系统、质量系统和公平系统三大方面构建了评价关天经济区新型城镇化水平的指标体系,然后采用PCA主成分分析法对关天经济区各市区2003—2012年新型城镇化综合水平进行了测定及排名。结果显示:经济区在10年间新型城镇化水平总体呈上升趋势,但仍存在基础设施落后、城乡居民收入差距过大、产业结构不合理等问题。因此,以强化城镇发展动力提升为目的,合理配置产业结构;以提升城镇质量为核心,加强城镇基础设施建设;以改善社会公平为着力点,缩小城乡收入差距成为应对关天经济区新型城镇化问题的必然选择。     

金融发展与城乡居民收入差距关系探讨--以中国西部12省区为例

文章基于2002-2011年中国西部12个省份金融市场（金融中介和保险市场）发展状况面板数据,建立回归模型,利用pooled LS回归和基于贝叶斯线性回归理论的MCMC算法,对西部地区金融发展与城乡居民收入差距之间的关系进行实证分析。研究结果表明：金融中介发展拉大了西部地区城乡居民收入差距,而保险市场发展则对西部地区城乡居民收入差距的扩大有抑制作用。并在文章的最后对出现这些情况的原因以及政策建议进行了阐述。     

秦汉焚尸非火葬刍议

秦汉史籍所记载的焚尸,并非传统意义上的火葬。这些焚尸的目的大多是对死者的一种羞辱和对生者的一种泄愤。与传统意义上的焚尸相比,不仅目的不同,而且主持焚尸者大多为死者的仇敌或敌人。焚尸过程充满暴力,缺乏火葬所必须的仪式。这种掘人祖坟、焚尸的行为与当时的社会伦理相背离,也与当时的丧葬礼仪格格不入。     

加入 WTO 以来中国出口商品竞争优势的演变

运用市场占有率、显示性比较优势、贸易竞争指数等指标,对2001—2012年我国进出口商品的数据进行分析,发现我国对外贸易整体竞争优势不断增强。对以SITC1位码水平下九类商品的竞争力指数分析,可以看出我国在劳动密集型产品上优势较明显,但有减弱迹象;我国资源密集型产品的国际竞争力越来越弱,资本和技术密集型的产品竞争优势逐渐增强。通过对不同技术含量制成品的贸易竞争力分析,发现我国低技术含量制成品竞争力在不断增强,具有较为明显的竞争优势,中等技术含量制成品中工程类制成品、加工类制成品及电子和电力类高科技含量制成品竞争力逐渐显现。     

Farm size,land ownership,and fertility in rural Egypt

The purpose of this paper is to present the findings of a household level analysis of land availability and fertility variation among farm families in rural Egypt. Data were drawn from a survey conducted in 2 predominantly rural governorates in Lower Egypt in 1978, Beheira and Kafr El Sheikh. They were purposely selected in an attempt to obtain areas representing a range of socioeconomic and demographic conditions. The analytical model that underlies the study postulates that fertility variation in rural areas is influenced by family access to land for cultivation purposes and the conditions governing that access, as well as socioeconomic and demographic control variables. Among the 561 households sampled, the mean value for land ownership was .47. The mean value for household income measured in Egyptian pounds was 112.83 with a standard deviation of 84.76 pounds. The females had been employed 9.7% of the years since marriage. On the average, women had completed less than 3 months of formal education--.32 years. Access to land cultivation was significantly related to the other variables. Land ownership increased with farm size. Family income was closely linked to cultivated area. Landless laboring families had the lowest fertility. Wives of landless laborers were on the average younger, slightly better educated, and less likely to have worked for wages since marriage. The results support the hypothesis that the amount of land available to the family for cultivation is positively related to fertility. Land ownership was negatively related to children ever born. Per capita family income also exerted a negative influence on the number of children ever born. This indicates that income levels were such that the positive nutrition-induced income effect on fertility does not seem to prevail. Age at marriage was negatively associated with fertility and was statistically significant. The strongest variable was the woman's age.     

高分辨率铁尾矿遥感光谱特征分析与信息提取

遥感监测尾矿是矿山调查和监管的科学方法,也是地理国情监测的基础内容。研究了铁尾矿遥感影像解译标志和光谱特征,建立铁尾矿遥感信息的提取技术流程。利用尾矿光谱特征与纹理结构的特点,构建了铁尾矿遥感增强处理的RTI数学模型。并以唐山地区的铁尾矿及固体废弃物作为研究区,分析了模型的影响因子和有效性。为尾矿资源的自动监测和目标提取提供了新的处理手段。     

我国房产税试点效果评析与房产税作用探究

目前我国房产税在持有环节的征收处于试点阶段，其推进和改革仍有很多争议。文章在总结国际上发达国家房产税征收及我国房产持有环节税收试点情况的基础上，从三方面分别探讨了在我国房价高启的背景下开征持有环节的房地产税的作用。但是这些作用还不能全面准确地涵盖我国应征收房地产税的所有层面，由此提出了适合我国国情的差别化房地产税收政策的构建思路。
