国际银行业并购的机理分析及对我国银行业的启示

20世纪90年代以来，第五次企业并购浪潮席卷全球，国际银行业在全球金融业务自由化和国际金融市场一体化的条件下,面对国际金融领域日益激烈的竞争，各大国际金融集团不断兼并重组，极大地改变了国际金融业的格局，掀起了空前的银行业并购高潮。本文从理论和现实的角度研究国际银行业并购这种经济现象，探讨中国银行业通过并购手段提高国际竞争力的必要性和可能性，并提出相应的并购策略，试图为中国银行业壮大资本实力，化解风险，切实提高竞争力提出可行的建议。这是本文写作的主要目的。 本文从银行并购的基本概念出发，通过对国际银行业并购的动因、发展特征、实现形式、制度环境条件及影响等方面的分析，揭示国际银行业并购的运行机理...学位：经济学硕士院系专业：经济学院财政金融系_金融学(含保险学)学号：B19993104

南海中深层动力格局与演变机制研究进展

南海是连接印度洋-太平洋的最大边缘海,在季风、海峡水交换以及复杂地形影响下,南海环流呈现出独特的三层结构以及远强于大洋的混合特征.理论与观测表明,南海内潮、内孤立波以及强风等过程是强混合的动力来源.在南海强混合作用下,南海发育了活跃的中深层动力系统,一方面促进了南海与大洋之间的水体交换,另一方面调控上层风生环流,使得南海环流显著区别于其他热带与副热带海盆.南海活跃的中深层环流所具有的物质搬运能力又显著影响着南海的地质沉积、生物地球化学循环等过程.中国对深海研究持续投入,在南海中深层环流动力学研究方面取得了显著的成果,文章就该方面进行总结,并对南海深海环流未来研究设想进行初步探讨

Distribution of particulate amino acids in the Changjiang Estuary and its adjacent sea and their indications for degradation and sources of organic matter

A total of 50 samples were collected to investigate the distribution and composition of particulate amino acids(PAA)in the Changjiang Estuary and its adjacent East China Sea in March, 2018. The results showed that the average concentration of PAA was(1.86 1.02)mumol/L(0.76~5.55 mumol/L). The major components of PAA in this study were Asp(aspartic acid), Gly(glycine acid), Ser(serine acid), Ala(alanine acid)and Glu(glutamic acid). The average concentrations of particulate organic carbon(POC)and particulate nitrogen(PN)were(74.21 37.70)mumol/L(18.06~238.66 mumol/L)and(7.52 3.46)mumol/L(2.27~ 19.86 mumol/L), respectively. The distributions of PAA, POC and PN showed similar trends, with elevated concentrations were found at the mouth of the Changjiang River and nearshore stations of the study area. The vertical distributions of PAA, POC and PN exhibited a uniform pattern. The C/N ratio in this study gradually decreased seaward, reflecting the influence of terrestrial input. Derivative parameters Asp/Gly and Ser + Thr [mol%] based on amino acids indicated that POM was dominated by diatomaceous organic matter, which might be due to the dominant growth of diatoms in the study area. No correlation were found between the PAA-C(N)% and the degradation index(DI), respectively. This discrepancy may be related to the application of PAAC(N)% and DI to different stages of degradation and the diversity of sources and transformations of amino acids
