A Study on Theory and Practice of Service for Taxpayers in China
纳税服务是政府履行公共服务职能的重要内容。开展和优化纳税服务,对于提高税收征管质量和效率,降低纳税遵从成本,保护纳税人的合法权益,引导纳税遵从,构筑和谐的征纳关系,具有十分重要的意义和作用。但是,由于理论准备的不充分和实践经验的不足,当前纳税服务工作还存在诸多突出问题。本论文试图在对纳税服务的一些基本理论和观点进行多维视角探讨的基础上,借鉴国际上现有的一些理论成果和成功经验,并紧密结合我国国情,提出我国纳税服务制度设计和优化的政策建议,寻求一条走向征纳和谐之路。论文共七章,各章主要内容如下:第1章“导论”。本章对纳税服务在我国的发展概况进行了描述,阐述了研究的重要意义,概述了国内外在纳税服务方...Service for taxpayers are one of the most important public services provided by the government.

Study on the Isolation, Identification, Bioactivity Screening and Secondary Metabolites of Cockroach symbiotic actinomycetes
天然产物是药物的重要来源。许多常用的临床药物均来自于微生物次级代谢产物。其中放线菌(Actinomycetes)在产生抗生素方面具有独特的优势,大约75%的抗生素都是由放线菌产生。从动物共附生微生物可以分离到许多结构新颖,生物活性多样的化合物。而昆虫共附生放线菌及其次级代谢产物的研究是一个新的领域。有可能对新药的研究及解决抗药性问题起到巨大的推动作用。 本论文对采集自厦门大学学生宿舍的蜚蠊进行体内(分为肠道和其他内脏)共附生放线菌的分离,共分离到50株放线菌。并对分离到的菌株进行了分子鉴定,通过16SrDNA的序列分析,结果表明所有菌株均属于链霉菌属。 以枯草芽孢杆菌(Bacillussu...Nature products are important source of Medicine. Many important clinical medicine are microbial secondary metabolites. Actinomycetes have a distinguished advantage in the field of producing antibiotics.

And entomic symbiotic actinomycete an...学位:理学硕士院系专业:生命科学学院生物学系_微生物学学号:2172006115213
Analysis of the Relationship between Economic Development and Environmental Pollution Emission Based on Panel Data--- An Empirical Study of Environmental Kuznets Curve in China
环境问题一直是关乎人类生存和发展的重要问题,2009年在丹麦哥本哈根召开的环境气候峰会更是把环境问题提到一个相当重要的高度,引起了全世界的关注。解决环境问题,创建理想家园,已成为全世界共同的目标。环境污染问题是当今社会对可持续发展问题探讨的重中之重,而其中的一个重要课题就是环境质量与经济增长之间的关系研究。环境库兹涅茨曲线(EnvironmentalKuznetsCurve,简称EKC)是用以描述环境污染与经济增长关系的一种经验曲线。Grossman和Krueger(1993)最早用数据对其进行了实证研究,他们以人均收入代表经济发展水平作为横轴,以排污量代表环境退化水平作为纵轴,排污量先随着人...Environmental pollution is an important topic related to human survival and development. In 2009, Copenhagen Climate Conference hold in Denmark put the environmental problems into a very important position and aroused worldwide attentions. Solving environmental problems and creating an ideal hometown become the common goal of human being. Environmental Kuznets Curve (EKC) is a curve that...学位:经济学硕士院系专业:王亚南经济研究院_西方经济学学号:2772007115224
Research on Motives and Value Effects of Foreign Currency Derivatives—Evidence from the MNCs in China
摘要 随着中国汇率形成机制市场化改革的不断深入,人民币汇率双向波动趋势凸显。在经济全球化背景下,中国跨国公司面临的外汇风险暴露问题日益加剧。外汇衍生品作为国外跨国公司进行规避商业风险和金融风险的工具,也逐渐在中国得到运用。但是,由于外汇衍生品自身所具有的杠杆性和复杂性,使其在使用过程中既可以帮助公司达到套期保值的目的,也会对企业价值造成难以挽回的损失。目前中国外汇衍生品市场的发展状况如何?促使中国跨国公司使用外汇衍生品的动机是哪些?外汇衍生品的使用对企业价值效应又是怎样?这些都是学术界和实务界关注的问题。 本文以2010-2014年中国跨国公司为研究对象,从外汇衍生品的使用动机,以及外汇衍...ABSTRACT With the development of the marketization of exchange rate reform in China, RMB exchange rate demonstrates the two-way fluctuation intensively. Under the background of economic globalization, Chinese multinational enterprises face a more serious foreign exchange exposure. Foreign currency derivatives, acting as the tool of against the financial risk have been gradually used in China. ...学位:管理学硕士院系专业:财务管理与会计研究院_财务学学号:2782013115014
Cultural Construction of the Johor Bahru Chinese Community:A Socio—Cultural Study on the Chinese Community in Johor Bahru,Malaysia after Word War Ⅱ
在对东南亚华人社会的研究中,华人的社会结构与文化形态始终是学界关注的重要课题。它不仅涉及伴随华南移民而来的中华文化在东南亚的传承与发展,亦是华人在当地社会变迁的历史脉络中,历经从移民到扎根的本土化转型的重要内容。本论文运用大量的中文、英文、马来文文献,包括档案资料、社团文献特刊、剪报、金石碑铭等,以及在马来西亚和中国潮州等地做实地的丰富田野调查、口述历史访谈和问卷调查,从历史学对时间、空间与人的透视,结合族群认同、文化建构等文化人类学理论,以位于马来半岛最南端的边城,柔佛州首府新山华人社会为研究对象,具体地考察与讨论华人社会在当地的历史和现实的情境中,基于本土关怀的自觉,如何进行华人文化再建构...Social structure and cultural patterns are always the main focuses of the study on Chinese communities in Southeast Asia.

Home Market Effect: An Examination of Motorcycle Industry in China
国际贸易理论里存在着两种解释贸易产生的原因和国家的产业结构的理论:比较优势理论和新经济地理学,比较优势理论认为贸易的产生是由于国家之间内在禀赋的不同,新经济地理学把贸易的产生归因于规模经济和产品差异化。新经济地理学的代表学者Krugman提出了著名的本地市场效应,即在存在着报酬递增和运输成本的世界里,国家常常成为有相对大的本地需求的产品的净出口国。在传统的比较优势贸易框架里是不存在本地市场效应的,因此,本地市场效应的存在与否是这两种理论区分的关键。 从20世纪末开始,中国很多城市采取了“禁摩限摩”政策,“禁摩限摩”政策打压了城市的摩托车需求,更进一步地,“禁摩限摩”政策打压了中国对高质量摩托...There are two theories explaining reasons for trade and industrial distribution. Comparative advantage theory holds that countries trade because of inherent differences. The economic geography theory holds that countries trade to take advantage of increasing returns and product differentiation. Krugman proposed a famous theory named home market effect based on the economic geography: In a world wi...学位:经济学硕士院系专业:王亚南经济研究院_金融学(含保险学)学号:2772011115269
Reflect upon Legal Regulation of Thin Capitalisation
“资本弱化”这种避税方式近年来日益引起国际税收领域的密切关注,这种避税方式与转让定价、注册避税港公司等避税方式相比,形式更加隐蔽,实践中不易觉察和对其进行监管。本文针对跨国投资者使用“资本弱化”避税的目的,结合国际实践,根据我国立法现状,提出目前对“资本弱化”的规制措施已不能适应经济发展的要求,并对如何将资本弱化控制在合理的范围内,在确保国家税收收入稳定的同时促进资源的优化配置作了深入探讨。Thin capitalisation, one way of global tax avoidance, has gained close attention among tax authorities internationally. It is harder to identify and attracts less scrutiny compared with transfer pricing, registration of companies for tax haven and other common means of tax avoidance. This paper investigates the development in international tax treaty and regulation of thin capitalization in developed countries. It proposes that effective regulations of thin capitalization come side by side with the progress of China economy focusing on problems arising from current legislation
