中国城镇居民人均可支配收入与消费支出的关系研究——基于变系数模型的分析

利用我国城镇居民人均可支配收入与消费支出的面板数据(1991-2009),采用变系数模型、协整理论等时间序列分析方法对其消费行为进行实证检验,并建立了城镇居民的消费模型,分析了边际消费倾向和自发性消费。结果表明:可支配收入与其消费支出之间存在着长期均衡的关系;当期收入是影响居民消费的最直接、最重要的因素,并据此提出相应的一些政策建议。     

基于ECM模型的成都市城镇居民收入与消费问题的实证研究

利用成都市1978—2007年度的城镇居民可支配收入和人均消费支出数据,构建误差修正模型进行了实证研究,结果显示：成都市城镇居民人均消费支出和可支配收入两变量存在协整关系;人均可支配收入是影响消费支出最根本的原因;由于误差修正系数为负数,符合反向修正机制,使得短期的消费政策无效。因此,长期来看,政府必须采取有效措施提高居民的可支配收入,优化供给和消费结构,才能实现扩大内需的政策目标。     

广东省城镇居民消费结构变动的定量分析

利用扩展的线性支出系统(ELES)，依据1997年及2003年广东省城镇居民年人均可支配收入和消费支出的截面数据，对广东城镇居民消费结构的变动情况进行定量分析。分析结果表明，广东城镇居民在“衣”和“食”得到满足之余，越来越重视对“住”与“行”的消费，同时，对精神文化、教育、交往联络、自身健康和保健也越来越关注，并提出了促进广东城镇居民消费结构优化和升级的几点建议。     

居民收入与通信网络市场经济效益研究--以河北省通信网络为实例

青岛市消费者安全海洋水产养殖品消费决策研究

以青岛市为样本,研究消费者对安全海洋水产养殖品消费决策行为,AMOS17.0软件模拟分析的安全海洋水产养殖品消费行为结构方程模型结果显示:个体特征对消费行为的影响不显著,但消费者的收入水平与家庭成员人数对安全海洋水产养殖品的消费决策不容忽视;消费者对所购水产品的经验积累、对水产品药物残留安全的认知、对政府"菜篮子"工程的认可以及对卖家口碑的了解,对安全水产品认知水平具有重要影响;购买地点的固定性与追求营养健康是安全水产养殖品消费动机形成的重要影响因子;在其他影响因子不变情况下,购后评价每增加1个标准单位,其对下一次购买的认知水平和消费动机将增加0.89和0.56个标准单位。     

实体-信息与场景-符号视角下的奶茶消费空间分布特征及影响因素

数字经济时代，实体空间与信息空间融合叠加、场景消费与符号消费共同作用的新零售消费空间对城市空间发展的影响不断扩大。以西安市新零售奶茶消费空间为研究对象，通过空间句法模型分析奶茶消费空间分布特征，构建门槛回归、多尺度地理加权回归模型对奶茶消费空间分布影响因素进行解析。研究发现：(1)新零售奶茶消费空间区位选择对市场信息高度敏感并能够回应空间调控决策，传统零售业区位论中涉及的消费市场、空间接近性、地价、同行业发展等因素仍对新零售奶茶消费空间分布产生显著影响，但实体与信息在新零售奶茶消费空间中存在尺度博弈，信息作用随着尺度的扩大而更加明显；(2)新零售奶茶消费空间分布中蕴含着品牌社群组织行为特征，消费社群的消费主体性增强，不同品牌新零售奶茶消费空间通过多种方式促进消费社群成长；(3)社会文化感知在实体与信息消费空间中均存在价格门槛效应。低价位消费空间场景与符号价值作用机制中信息流与物质流之间相互排斥，文化扩散依靠场景与符号密度、传播速度与频次。高价位消费空间场景与符号价值作用机制中信息流与物质流相互促进，文化扩散依靠场景与符号影响力和传播距离。(4)空间句法模型模拟了实体消费的信息空间延展，...     

不同消费群体对经济增长的作用及收入政策分析

根据我国个人消费者的不同消费水平，可将其划分为四种不同类型的个人消费群体，即百元级消费群体主要是农民消费群体（I类），千元级消费群体主要是工人消费群体（Ⅱ类），万元级消费群体主要是公职人员消费群体（Ⅲ类），十万元级消费群体主工是个体经营者和私人企业主消费群体（Ⅳ类），在四种消费群体中，对经济增长起决定作用的是Ⅱ类和Ⅲ类消费群体，他们数量较大而且消费水平适中，I类消费群体虽然数量很大，但是消费水平较低，对经济增长的短期效果不明显；Ⅳ类消费群体消费水平较高，但人数较少，对经济增长可起到一定的示范作用。因此，对四类不同消费群体的个人收分配政策是：减轻农民负担，增加农民收入；扩大工人就业，完善社会保险制度；有限度地提高公职人员收入，促进其消费水平提高；调节个人经营者和私人企业主的个人收入，引导其合理消费。

中国资源型城市产业结构提升的思考

资源型城市是城市职能分类中的一个重要类别，它是反映以自然资源开发为主要职能的城市。资源型城市是随着社会分工的发展，以自然资源为开发对象的资源产业（资源生产和资源初加工产业）及相配套的社会劳动集中到一定规模后所形成的。 我国资源型城市的大量产生，既是我国大规模经济建设和加速工业化进程的需要，也是我国“把消费城市改造成生产城市” 的城市建设方针的必然产物。资源型城市特别是矿业城市在支撑和促进国民经济发展中，具有特别重要的地位与作用。然而随着我国经济社会的持续发展，以及大量科技含量高的新兴产业的出现，广…     

Thermohaline structure inhomogeneity associated with polynia at the northern margin of Emery Ice-shelf

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area.     

Phylogenetic analysis of cultivable bacteria isolated from Arctic sea-ice

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter.

Relationship of Arctic sea ice and Northern Hemispheric 500 hPa Polar vortices

Using the NCEP/NCAR reanalysis monthly 500 hPa height data on a 2.5 latitude-longitude grid and 1°×1° sea ice data,the polar vortex area,intensity index and arctic sea ice area index are calculated respectively,and the meridional distribution,period variation and the abrupts in the long range trend are analyzed to study their relationship.The results show that the meridional distribution of sea ice and polar vortex h-ave distinctive difference,the relative positions of them are different in the eastern and western hemispheres,and exept they have periods of 4 months,quasi half year,quasi year,4-5 years and 10 years commonly,and each of them has its own respective variation as well.The sea ice area is decreasing apparently since 1980's,so is the polar vortex area,but their abrupt changge time are different totally.The area of sea ice and polar vortex has prominent positive correlation,but the relationship of sea ice intensity,polar vortex intensity,polar vortex area is complicated.     

Preliminary study on plasma membrane fluidity of Psychrophilic Yeast Rhodotorula sp.NJ298 in low temperature

The ability of cell to modulate the fluidity of plasma membrane was crucial to the survival of microorganism at low temperature. Plasma membrane proteins, fatty acids and carotenoids profiles of Antarctic psychrophilc yeast Rhodotorula sp. NJ298 were investigated at -3 ℃, 0 ℃ and 8 ℃. The results showed that plasma membrane protein content was greater at -3 ℃ than that at 8 ℃, and a unique membrane polypeptide composition with an apparent molecular mass of 94.7 kDa was newly synthesized with SDS-PAGE analysis; GC analysis showed that the main changes of fatty acids were the percentage of unsaturated fatty acids (C18∶ 1 and C18∶ 2) and shorter chain saturated fatty acid (C10∶ 0) increased along with the decrease of the culture temperature from 8 ℃ to -3 ℃; HPLC analysis indicated that astaxanthin was the major functional carotenoids of the plasma membrane, percentage of which increased from 54.6±1.5% at 8 ℃ to 81.9±2.1% at -3 ℃. However the fluidity of plasma membrane which was determined by measuring fluorescence anisotropy was similar at -3 ℃, 0 ℃ and 8 ℃. Hence these changes in plasma membrane's characteristics were involved in the cellular cold-adaptation by which NJ298 could maintain normal plasma membrane fluidity at near-freezing temperature.
