Studies on the Net Errors and Omissions of China’s Balance of Payments

内容摘要2002年，中国国际收支平衡表上出现一个令人瞩目的新亮点，那就是净误差与遗漏项目差额由十几年来一直出现在借方（即逆差状态）突然转向了贷方（顺差），并持续至今。本文正是针对这一情况，试图寻找净误差与遗漏变动的轨迹，以及它同国际收支稳定性结构之间的联系：（1）净误差与遗漏项目的阶段性表现是否反映国际收支结构中的不稳定性因素，是否预示国民经济运行过程中出现的隐患；（2）国际收支稳定性结构中所包含的净误差与遗漏项目应该具备哪些特性，国际收支平衡表上两大一级账户（经常账户及资本金融账户）组合结构（经常账户差额状态——资本金融账户差额状态）如何约束净误差与遗漏项目，以便通过对净误差与遗漏项目变动的...Abstract In the year of 2002, it is a new brightness that the Net Error and Omissions transferred from the long-lasting debit balance to credit balance, which is different from other countries, fixed the eye of the world, and brought the newly international judgment on Chinese economy. The Research on the Net Error and Omission is becoming more and more intense. The Net Error and Omissions ite...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：20034200

A Study on Creativity and Sustainable Development of Economy

一直以来，物质资本、人力资本、技术进步和政府行为被认为是影响经济发展的主要因素。但自从进入知识经济以来，创意的重要性不断得到肯定和重视，甚至被视为一个国家或地区经济发展的关键因素，创意产业也成为经济新的增长点，创意经济则逐渐成为一种新型的经济形态。创意在经济、社会和文化方面表现出天然的可持续性特征和优势，本文尝试从增长和发展的理论视角探索性的研究创意促进经济可持续发展的作用机制。现代经济可持续发展主要体现为持续的技术进步，而创意对经济可持续发展的作用机制可从两个方面来解读：其一，创意作为一种知识型增长要素，它能加快技术进步，提高要素生产率，转变经济增长方式，促进经济的可持续发展；其二，创意的具...Has been physical capital, human capital, technological progress and the government behavior is considered to be the main factors affecting the economic development. However, since the knowledge-based economy, the importance of creativity continues to get recognition and attention, or even as a key factor of economic growth of a region or a country；the creative industry has become a new growth poi...学位：经济学博士院系专业：经济学院经济系_西方经济学学号：1532008015029

商业银行公司治理的国际经验与启示

优化公司治理结构是目前我国商业银行改革,尤其是国有商业银行股份制改革的核心内容。在当前中行和建行股份制改革试点取得重要进展的形势下,合理的治理结构将为其成功上市提供良好的运作基础。本文从公司治理中利益相关者理论分析入手,介绍国外商业银行政府宏观治理和银行微观治理的主要模式,分析其中可供借鉴的经验,并结合我国实际提出完善我国银行治理结构的对策建议

载体酸碱性对高硫合成气制甲硫醇的K-Mo-Co催化剂结构和性能的影响

选取3种酸碱性不同的载体(γ-Al2O3,SiO2,MgO)制备由高硫合成气制甲硫醇的负载型K-Mo-Co催化剂。它们的活性高低顺序为:K2MoCo0.35O/SiO2>K2MoCo0.35O/γ-Al2O3>K2MoCo0.35O/MgO;程序升温脱附表征结果显示,这3种不同载体的催化剂与载体的酸碱性强弱顺序一致,弱酸性载体制备的催化剂对合成甲硫醇有利;H2程序升温还原和激光Raman光谱表征结果显示,碱性载体制备的催化剂中,Mo以易于还原和硫化的八面体构型存在,硫化后主要以MoS2存在;弱酸性载体制备的催化剂中,Mo以难于还原和硫化的四面体构型存在,硫化后主要以氧硫钼物种存在,这些物种与合成甲硫醇密切相关

钾修饰的MoO_3/SiO_2催化剂的XRD和TPR表征

采用XRD和TPR测试技术表征了一系列不同K与Mo摩尔比的MoO3/K2O/SiO2催化剂。XRD表征结果显示,随着元素K的加入,多钼物种逐渐被破坏,最终形成了单钼的K2MoO4物种。TPR表征显示,催化剂表面的钼物种有2种结构,即八面体的Mo(Oh)和四面体的Mo(Td)。八面体Mo(Oh)的还原峰在770 K附近,而四面体Mo(Td)还原峰在1 000 K附近;无K的MoO3/SiO2催化剂的低温还原峰出现在840 K,少量元素K的添加削弱了Mo与SiO2之间的作用,使得低温还原峰温度降低到770 K附近;随着元素K添加量的进一步增加,Mo(Oh)物种逐渐减少而Mo(Td)物种逐渐增多,从而使得催化剂表面的Mo更难被还原。高硫合成气制甲硫醇的活性随着钼基催化剂八面体(Oh)钼物种的增加而增加
