城乡居民收入分配现状及其对策的思考

建国以来 ,我党一直在为提高人民的生活水平而努力 ,其中有很多宝贵的经验和深刻的教训 ,特别是 1978年改革开放以来 ,我国居民个人收入总量急剧增加。然而 ,居民收入分配差距也在不断扩大。本文列举了居民收入分配差距不断拉大的几种主要原因 ,并且根据我国收入差距演变的情况 ,提出了适合我国国情的对策 ,以求实现缩小居民收入差距 ,达到共同富裕的目的。     

区域主导产业关联分析

区域产业结构调整过程就是主导产业选择过程。选择区域主导产业是选择那些产业关联度高的产业。运用投入产出法分析区域主导产业的关联情况并利用产业感应度系数和影响力系数的模型公式选择区域主导产业,是进行区域主导产业选择的重要方法和依据。     

Another look at across-crime similarity coefficients for use in behavioural linkage analysis: an attempt to replicate Woodhams,Grant, and Price (2007)

Abstract

In the absence of physical evidence, investigators must often rely on offence behaviours when determining whether several crimes are linked to a common offender. A variety of factors can potentially influence the degree to which accurate linking is possible, including the similarity coefficient used to assess across-crime similarity. The current study examines the performance of two similarity coefficients that have recently been compared to one another, Jaccard's coefficient (J) and the taxonomic similarity index (Δ_s), using samples of two crime types, serial homicide (N=237) and serial burglary (N=210). In contrast to previous research, the results indicate that Δ_s does not significantly outperform J with respect to linking accuracy. In addition, both coefficients lead to higher levels of linking accuracy in cases of serial homicide compared to serial burglary. Potential explanations for these findings are presented and their implications are discussed.     

The Assessment of the Impact of an Aging Population of China on the Country＇s Economy

In the article, the author on the basis of the analysis of the structure of the population of the People＇s Republic of China （PRC） is making an attempt to identify the influence of increasing number of people over 65 years on the economic situation in the state. The introduction of reform of pension system of China is related to the additional expenses of the state. Basing on the method of pair correlation, the author shows that with increase of percentage of the aging population of PRC, the foreign exchange reserves of the state are increased; it is evident that the state forms the financial reserves for the pension fund of the country.     

对我国现阶段收入分配差距的几点分析

总体收入分配差距和城乡收入分配差距是反映居民收入分配差距的两个主要方面。 2 0 0 0年我国居民总体收入分配的基尼系数已经超过国际公认的警戒线 0 .4的标准。2 0 0 1年城镇居民年人均收入与农村居民年人均收入之比已经达到创记录的 2 .90∶1。收入差距及其扩大会带来某些负面后果 ,甚至极大地危害社会的稳定和正常运转 ,但是合理的、适度的收入差距往往具有积极的社会效应。     

辽吉黑与江浙沪六省市制造业集聚水平的比较分析

通过运用产业地理集中度等统计模型,以1998年到2008年的数据为基础,对东北三省与江浙沪制造业的数据进行了对比分析。结果显示,东北三省制造业的发展程度明显低于江浙沪的制造业发展层级,规模优势仍然集中在传统重化工业上,依靠能源、资源的优势发展了自己的制造业产业集群。尽管发展程度落后于江浙沪等省市,但从数据的分析中也看出,东北三省制造业的集聚程度已经形成了一定的规模,并在能源的开发与利用、资源的生产与深加工方面都有着自己特有的产业优势,特别是在新型制造业领域也逐渐赢得一定的发展空间,为今后东北三省制造业的转型与升级换代提供了良好的发展前景。     

Wind-drag estimation in a traffic accident involving a motor scooter and a tractor-trailer

This case report describes a noncontact traffic accident involving a motor scooter and a tractor-trailer with a focus on the wind-drag effect. We used load cells to measure the drag force acting on a substantially similar motor scooter when a substantially similar tractor-trailer passes by it, taking into consideration various speeds of the tractor-trailer and distances between the two vehicles. A three-dimensional steady-state flow analysis was also performed by using the CFX program for computational fluid dynamics to examine the streamlines and the pressure distribution around the tractor-trailer at various speeds. From the experiment, for a separation distance of 1.0 m (3.28 ft) and a speed of 90 km/h (55.9 mph), the maximum resultant drag force is 124.5 N (28 lb); this constitutes a degree of force that could abruptly disrupt the stability in maneuvering by an operator who is unaware of the approaching tractor-trailer. In addition, a single equation that relates the tractor-trailer speed to the drag force that acts on the motor scooter was derived on the basis of the Reynolds number (Re) and the wind-drag coefficient (C(d)): C(d) = 1.298 × 10(-7) Re.     

Rising Inequality in Mexico: Household Characteristics and Regional Effects

We use an empirical framework to identify the contributions of microeconomic factors to the sharp rise in household (per capita) income inequality in Mexico between 1984 and 1994. Results indicate that changes in returns to household characteristics, in particular changes in returns to education, are responsible for about half of the increase in the Gini coefficient. The deteriorating conditions in rural areas relative to the urban areas and of the southern region relative to other regions account for another fourth of the increase in the Gini.

构建和谐社会必须消除的不和谐因素--城乡居民收入差距扩大的成因分析

我国目前正进入经济社会发展的关键阶段.这个发展阶段的特点有两个:一个是整个社会进入"黄金发展时期",经济社会协调发展;另一个是整个社会进入"矛盾凸现时期",经济社会徘徊不前,甚至出现社会动荡和倒退.这一阶段可能会呈现出两种社会发展前景:一是执政思路清晰,政策妥当,就可以进入和谐社会;二是执政党和政府政策失误,不但会使经济停滞不前,而且会激化社会矛盾,危及政权的稳定.具体分析我国社会目前所存在的一些不和谐因素,比如城乡居民收入差距扩大问题等,则能更加清楚地看出中央做出构建社会主义和谐社会这一决策的深谋远虑.
