黑龙江省城乡居民消费结构比较分析

运用扩展线性支出系统模型,从边际消费倾向、基本消费支出和收入弹性3个方面,对黑龙江省城乡居民的消费支出结构进行了实证分析.结果表明,黑龙江省城乡居民的消费结构和生活水平存在显著差距,城镇居民发展型和享受型消费支出的比重较高,交通和通讯已经成为当前的消费热点;农村居民的边际消费倾向很低,基本消费支出在实际消费支出中所占的比重偏高,其中,食品和居住2项的基本消费支出所占的比重最大,是黑龙江省农村居民目前的消费重点.     

甘肃省农村居民生活消费需求变动分析

为了应对国际金融危机,中国提出了"扩大内需以促进经济发展"的政策.正是基于这一政策背景,研究甘肃省农村居民消费水平和消费结构,得出甘肃省农村居民消费主要集中在食品、居住、文教娱乐等生活消费需求方面.随着生活质量的改善,对医疗保健和交通通讯消费存在潜在需求,消费结构正在逐步趋向合理化.进一步扩大农村居民消费需求的关键在于大力提高农村居民收入和改善农村消费环境.

我国四大区域城乡居民消费倾向比较分析

依据1992～2008年<中国统计年鉴>数据,采用回归模型对我国东部、东北、中部、西部城镇及农村居民收入和消费的关系运用最小二乘法和广义最小二乘法进行实证分析.结果表明,我国四大区域城乡居民消费倾向具有显著特征,从区域上看,城镇居民边际消费倾向呈不规律波动,而农村居民的消费倾向则遵守边际消费倾向递减规律;从时间序列上看,我国四大区域农村居民边际消费倾向呈"多U型"变动趋势,不同地区农村居民边际消费倾向变化有一定的差异,而城镇居民边际消费倾向则呈小频率宽幅波动趋势;四大区城城镇和农村居民平均消费倾向均呈递减规律.为扩大消费,促进区域经济均衡协调快速发展,针对城乡差异及不同地区的特点,提出采用有力措施提高城乡居民消费倾向,制定和实施刺激消费的区域性政策.     

基于主成分分析法的我国农村居民消费结构的综合评价

为研究农村居民的消费结构,根据<中国统计年鉴2010>中的数据,对2009年我国各地区农村居民家庭平均每人生活消费支出作主成分分析.提取了1个主成分,根据主成分得分对全国31个省(自治区、直辖市)进行排序,上海得分最高,排名第1;东南部沿海省份、东北以及北京、天津排名靠前;以河北、山西、湖北等为代表的华北、华中地区主成分得分为负,略低于全国平均水平;贵州、西藏、甘肃等西部地区排名最后.并对各地区农村居民消费结构进行分析,给出了促进农村居民消费的建议.     

收入性质对居民消费结构升级的影响分析

根据中国1997年-2008年30个省(区、市)的面板数据,考察收入性质对全体居民、城镇居民和农村居民消费结构升级的影响.结果表明:收入增长性、收入永久性和收入不确定性三种收入性质对居民消费有不同的影响,即使同一收入性质对居民消费的影响方向和影响程度也不同.就收入性质对居民消费结构升级的影响而言,城镇与农村有所差别.     

新疆城乡居民消费结构的实证分析

从线性扩展支出系统(ELES)入手,依据<新疆统计年鉴>数据,对新疆城乡居民的消费结构进行了实证分析,在对边际消费倾向、收入弹性和价格弹性进行比较分析的基础上,得出新疆城乡居民的消费结构存在明显差异的结论,并为改善这些差异提出了相应对策建议.     

改革开放以来居民消费方式的变化及其反思

改革开放以来,我国居民的消费方式发生了极其深刻而广泛的变化,这些变化分别体现在消费水平、消费结构、消费形式、消费观念以及消费功能和地位五个方面.以此为依据,反思我国居民当前的消费方式,提出四点建议.一是要进一步明确社会主义市场经济的目标是满足人民群众物质文化生活需求的理念;二是要加快产业结构的优化升级,以此促使消费结构的优化更新;三是要发展新型购物方式,推动消费形式走向便捷、省时、高效;四是要加强对居民消费观念的引导,推进居民消费方式健康、可持续地发展.     

从刺激消费看新型农村养老保险制度

新型农村养老保险制度,具体表现在增加老年人收入,减轻农村居民的养老负担、制度保障农民养老.改变"储蓄养老"的农村养老现状等几个方面,新型农村养老保险制度对拉动农村居民消费需求起到了很大的促进作用.但是目前我国新型农村居民还有很多尚未满足的消费需求,所以新型农村养老保险制度惠及各类农村主体在养老制度保障下,将在带动我国的国内消费方面能起到更大的作用.

根据实际转炉建立实体模型。以有限元为手段,考虑了炉衬和炉壳材料的物性参数随温度变化的特点和炉衬与炉壳之间膨胀间隙,计算了转炉炉壳在温度载荷和炉衬膨胀压力同时作用下的热应力。所得结果可为转炉炉壳设计提供依据。     

The effect of amount of possession of the trait of hostility on accuracy of perception of hostility in others.

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

Comparison of rates of infection of two methods of emergency ventricular drainage

The rates of infection of two methods of external ventricular drainage in use at Atkinson Morley's Hospital--namely, (a) percutaneous drainage with Rickham reservoirs and (b) tunnelled ventriculostomies--were compared in this retrospective review. Percutaneous drainage of CSF with Rickham reservoirs was associated with a 27% rate of infection as identified by positive microbiological cultures; tunnelled ventriculostomy catheters had a 10% infection rate. The difference in the infection rate between the two methods was statistically significant (P < 0.015). Other variables examined, including the age and sex of the patients and the reasons for ventricular drainage, were not associated with an increased rate of infection. Most infections from either method were caused by a coagulase negative staphylococcus. The average duration of ventricular drainage before identification of positive cultures was 5.7 days for Rickham reservoirs and 6.0 days for ventriculostomies.

Results of treatment of cancer of the cardia

Cancer of the cardia is traditionally discussed with cardiac cancer of the lower portion of the esophagus and upper gastric cancer invading the esophagus, and the specific characteristics of cancer of the cardia have never been clearly defined. We reviewed the outcome of 172 patients with adenocarcinoma of the cardia who had undergone radical surgery between 1949 and 1994 in the Division of Gastrointestinal Surgery of the Cancer Institute Hospital. The centers of the tumors were located within 2 cm above and below the boundary between the esophagus and the stomach, and their longitudinal diameter was less than 8 cm. We divided the patients into an early period (1949-1979; n = 79) and a late period (1980-1994; n = 93), and focused on the historical transition. There were no differences in patient gender or histology between the two periods. However, the late period was associated with fewer cases of esophageal invasion and shorter longitudinal diameter, as the age of the population advanced. The number of advanced cancers such as the localized and infiltrative type had decreased, and early cancer and early clinical stage had become more common, but despite the fact that the number of early cancers had increased, extended dissection, such as thoracic and paraaortic lymph node dissection, was performed more frequently. By clinical stage, the long-term outcome markedly improved in Stage I patient in the late period, and tended to improve in Stage II and III patients. This appears to have been attributable to the prevention of micrometastasis by extended dissection, although the number of early cancers is another major potential cause. There were no differences in the outcome of Stage IV patients between the two periods, and further advances in multimodality therapy must be awaited. The range of resection is basically proximal gastrectomy, and if there are adequate indications, the prognosis is favorable. In view of the status of lymphatic flow and lymph node metastasis, and long-term results, lateroaortic lymph node dissection is important. Since the number of early cancer patients has been increasing, if intraabdominal recurrence is prevented, intrathoracic lymph node dissection will contribute greatly to the outcome of such patients.

Comparison of the results of surgical and conservative treatment of fractures of the diaphysis of the tibia

In this paper is treated the fundamental problematic of the fracture of the diaphysis of the tibia and the therapeutic results after the conservative and operative treatment are confronted. Among 518 patients with 433 open fractures and 35 with closed fractures of the diaphysis of the tibia, successful treatment of more 2/3 was obtained in the period from 1968 to 1972. Following our casuistics and literature, whose results are similar, we find out that the average total treatment of the osteosynthesis of the fracture of the diaphysis was shortened for 2,5 months depending upon the type and the localisation of the fracture. Apolied methods of the operative and conservative and conservative treatment in relation to the velocity of the medical cure as well as to the extreme anatomical-functional results are analised. We noticed that osteosynthesis, made by the intermedullary nail and the extension of the canals or by a small AO table, by the achieved stability makes conditions of immediate motions and an early rehabilitation. Because of that it gives the best functional results.
