International Trade of China:From the View of Financial Development Effect

通过引入金融制度因素对HECHSCHEr-OHlIn-SAMuElSOn(HOS)基准模型进行扩展,分析了不合理的金融体制下中国制造业国际分工地位总体低下的现状。结合中国的情况,讨论了由于中央政府、地方政府不合理的经济管制导致的金融市场分割,使得社会要素禀赋结构出现错误的配置。因此,完善金融资源的市场化配置,对于中国产业技术结构和经济结构的升级与变迁极为重要。在推进金融市场化、自由化的过程中,对风险问题必须加以审慎的考虑。This paper applies the financial contract model of Holmstrom and Tirole to the HOS model,attempting to analyze how financial system lead to the low status of China industry.Basing on the situation in China discussing the central government,local government economic regulation cause unreasonable financial market segmentation,so that endowment structure of society configuration emerge.Market-oriented financial resources allocation is important to upgrading China's industrial and economic structure.At the same time,the risks must also be carefully considered in the process of liberalization

The Welfare Analysis and Empirical Test of RMB Exchange Rate Regime Choice and Transition

汇率制度选择和转型理论乃现代汇率理论之核心内容，并伴随着实践而不断丰富和发展。然而，与研究一个经济体内部的宏观和微观经济学相比，目前汇率制度选择和转型理论还比较稚嫩，不尽成熟。其根本原因在于，理论研究所涉及的问题极为复杂，汇率制度选择虽然是一个国家和地区的主权行为，但其行为和目标选择除受本国经济环境的影响以外，还会受到本国政治环境，如政治稳定性的影响，也会受到国际环境和周边政治经济环境的影响。因此之故，各种研究成果存在较大差异，容易陷入“没有一种汇率制度在任何时候都适合于任何国家”的不可知论的陷阱，因而难以形成一个一般性的理论也就在所难免。 对我国而言，随着经济持续快速发展和对外开放不断扩大...The Theory of Exchange Rate Choice and Transition is the core of the Modern Exchange Rate Theory, continuously enriched and developed with practice. However, compared to the macro and micro economics which research the problem within an economy, the Theory of Exchange Rate Choice and Transition is still relatively immature, not complete at present. The fundamental reason is that the involved theor...学位：经济学博士院系专业：经济学院经济研究所_政治经济学学号：2902007015393

E-mai:l [email protected][中文文摘]目前中国红树林湿地共记录了2854种生物,包括真菌136种、放线菌13种、细菌7种、小型藻类441种、大型藻类55种、维管束植物37种、浮游动物109种、底栖动物873种、游泳动物258种、昆虫434种、蜘蛛31种、两栖类13种、爬行类39种、鸟类421种和兽类28种。这些动物中有8种国家一级保护动物,75种二级保护动物。中国红树林湿地是中国濒危生物保存和发展的重要基地,并在跨国鸟类保护中起着重要作用。中国红树林湿地单位面积的物种丰度是海洋平均水平的1766倍。从初级生产物质基础、食物关系多样性、宏观尺度和微观尺度的空间异质性、生境利用的时序性等方面分析了中国红树林湿地物种多样性极其丰富的原因。 [英文文摘]To date,total of 2854 species of organisms were recorded in Chinese mangrove wetlands,including 136 species of fungi,13 species of actinobacteria,7 species of bacteria,441 species of microalgae,55 species of macroalgae,37 species of vascular plants,109 species of zooplankton,873 species of macrobenthos,258 species of nektons,434 species of insects,31 species of spiders,13 species of amphibians,39 species of reptiles,421 species of birds and 28 species of mammals.Among them,8 species belonged to the category 1 of Chinese national protected animals and 75 species belonged to the category 2.Chinese mangrove wetlands are very important bases for the conservation and development of the endangered species to China,and playing a critical role in the international activities for protecting the migrating birds.The species abundance in Chinese mangrove wetlands was 1766 times as much as that for the averaged species abundance in Chinese sea fields.The prolific species diversity in Chinese mangrove wetlands can be attributed to their high primary productivity,high diversity in their consumers’ food preferences,high spatial heterogeneity at macroscopical and microscopic scale levels,and their dynamic temporal sequence in habitat utilization.国家自然科学基金资助项目(40676050);联合国环境规划署(UNEP)全球环境基金(GEF)资助项目;广西科学基金资助项目(0640014

溶菌酶1在小鼠超数排卵前后孵化及休眠囊胚中差异表达的研究

目的研究溶菌酶1(lysozyme 1,LYZ1)基因在超数排卵前后小鼠孵化囊胚和休眠胚胎中的分布以及表达,探究动物胚胎着床过程中新的调节机制。方法从妊娠5 d ICR小鼠体内获取的正常孵化囊胚和超排囊胚,利用小鼠延迟着床模型于妊娠第8天获取休眠胚胎和超排休眠胚胎。利用免疫荧光和Western Blot方法检测LYZ1蛋白在四组胚胎中的分布和差异表达变化。结果 LYZ1在超数排卵前、后小鼠孵化囊胚和休眠胚胎中均有表达,且主要集中在内细胞团中,滋养层细胞和胞质中少见分布;与未进行超排的小鼠相比,LYZ1蛋白在超排后小鼠胚胎中表达量显著上调,与未营造休眠模型的小鼠相比,LYZ1蛋白在休眠模型小鼠胚胎中的表达量显著上调。结论 LYZ1蛋白在囊胚内细胞团中表达,可能参与调节胚胎内细胞团的发育;LYZ1蛋白在超排-休眠胚胎中的高表达,说明LYZ1蛋白在休眠和超数排卵的双重影响下,会因为抵御不利环境而上调。2016年度科技创新服务能力建设-科技计划重点项目(KZ201610020018);;2018科技创新服务能力建设(KZ201610020018)~

Over One Hundred Year Sedimentary Record of Polycyclic Aromatic Hydrocarbons in the Andaman Sea, Malaysia

[摘要]：采用GCPMS 分析研究了马来西亚海域安达曼海兰卡威岛邻近海域沉积物柱样(WC02) 中多环芳烃(PAHs) 组成与含量的 垂直分布特征, 结合210Pb定年, 重现了该海域近百年来PAHs 的沉积历史( 1898~ 2004 年) . 研究表明, PAHs 在整个沉积剖面( 0 ~ 56 cm) 的含量介于1312~ 6011 ng# g- 1 之间( 平均值2814 ng# g- 1) , 所分析的PAHs 中以菲、萘、等化合物为主, 与当地周边海 域相比污染程度较轻. 在20 世纪20 年代以前, 沉积物中多环芳烃含量较低, 基本代表当地环境的本底值, 即多环芳烃主要来 源于天然物质的输入; 20 年代以后PAHs 的总量有所上升, 并在20 世纪60 年代和80 年代出现了2 个峰值, 表明这段时间内多 环芳烃的陆源输入特征比较明显, 也反映了人类活动在20 世纪20 年代后开始对该海域产生一定的影响. 采用母体、高低环 PAH 比值对沉积物柱样中PAHs 的来源进行分析, 表明该海域沉积物受到燃料不完全燃烧产物污染为主、并伴有石油类污染, 这与马来西亚西海域周边地区的人类活动( 工农业生产、进出口、海上活动等) 密切相关, 同时也受到马六甲海峡繁忙的海上 交通运输影响. 对沉积物柱样污染历史进行分析, 表明PAHs 含量的阶段性变化与该地区不同时期的人文活动和社会经济( 国 内生产总值) 的发展状况密切相关, 较好地反映了人类活动对环境的影响.[Abstract]:Polycyclic aromatic hydrocarbons (PAHs) in a sediment core collected from Langkawi Island of the Andaman Sea, Malaysia were determined by GCPMS, the vertical variations of concentration and distributions of PAHs were investigated. In combining with 210Pb2dating, the PAHs sedimentary record in the last 100 years was reconstructed and their possible sources were also discussed. The EPAH concentration ranged from 131226011 ng#g- 1 in the whole sedimentary section ( 0256 cm) with the dominant compounds of phenanthrene, naphthalene and perylene. The sediments contaminated to a lesser extent comparing with the surrounding waters. Before the 1920s, the concentrations of PAHs were considered to be the background level, which was implied from the natural inputs. The historical records of PAHs in the core showed that two distinct peaks which represented the input time of 1960s and 1980s, respectively, inferred that there were some relatively dramatically land2based inputs, and human activities leaded a clear impact to these waters during these periods. Furthermore, PAHs diagnostic ratios indicated that PAHs in the core sediments were mainly of pyrolytic origin ( combustion) , accompanied with minor petroleum origin. These were related with agriculture, industry, ocean import and export, and shipping activities in the surrounding regions. Meanwhile as the vital communication line, the marine transportation of the Strait of Malacca had influenced the environmental quality of the Andaman Sea. Meanwhile, based on the sedimentary record, PAHs concentrations were found to correlate positively with humanism activities and socioeconomic development (Gross Domestic Production) in the surrounding regions.国家自然科学基金项目( 20777060) ; 国家海洋局海洋三所 科技项目( 海三科2007021

The Analysis of International Capital Flows in Marxist Theoretical System

虽然马克思在《资本论》及其著作中并没有专门论述国际资本流动问题,但其经典著作中仍然包含了十分丰富的国际资本流动思想。马克思主义的国际资本流动理论科学地揭示了国际资本流动在本质上的二重性特征,及其在世界经济格局、货币效应和经济危机的国际传递性三个方面的经济效应,为分析和研究当前国际资本流动奠定了理论基础。Although Karl Marx did not specifically address the issue of international capital flows in‘The Theory of Capital’,his classic works still contain a very rich thought of international capital flows.Marx showed the nature of international capital flows and its effects on the world economic pattern,currency effects and the international transmission of the economic crisis.His analysis and research have laid a theoretical basis for international capital flows research
