    二战以后,由于世界各国经济交往日益增多,经济全球化进程进一步加快。因此各国的宏观经济运行不可避免的会受到全球经济状况的影响,各国之间的宏观经济政策也会相互影响。在经济不景气的情况下,各国会采用财政政策和货币政策来刺激经济。而在经济全球化的今天,一个国家的经济不仅受到国内经济政策的影响,同时也会受到其他国家经济政策的影响。实际汇率作为衡量两国商品相对价格的经济变量,反映了一国的竞争力,也会受到本国和外国经济政策的影响。但财政支出会怎样影响实际汇率呢?主流的经济学理论认为财政支出会导致实际汇率升值,但相关实证文献却没有得出和理论预测一致的结论。为了进一步研究该问题,本文使用localproject...After World War II, the economic exchanges between the countries in the world are increasing, and the process of economic globalization is speeding up. Macroeconomic operation of countries will inevitably be affected by the global economic situation and macroeconomic policy will affect each other. In the periods of recession, countries will use fiscal policy and monetary policy to stimulate the ec...学位:金融硕士院系专业:王亚南经济研究院_金融硕士学号:2772014115276

    填海造地在解决海岸带地区发展空间短缺问题的同时,严重损害了人类赖以生存和发展的海洋与海岸带生态系统。如何控制大规模填海造地是我国面临的重大课题。构建了估算海湾最大可允许填海造地面积的分析框架和模型。填海造地的各种收益和成本,包括环境和生态成本被系统性地量化并嵌入到框架和模型之中。模型的估算结果可以为实施控制填海造地的约束机制提供科技支撑。利用建立的框架和模型对厦门西海域模拟的结果显示:当贴现率为4.5%时,厦门西海域最大可允许填海面积是89.44 HM2,其面积至少应该保持在44.52 kM2;即便是使用8%的高贴现率,最大可允许填海面积也只占规划填海面积的35.83%;如果采用更加重视环境与生态效益的低贴现率2%,则厦门西海域最大可允许填海面积是0。While creating useful space for agriculture,industry,and urban development,coastal reclamation damages considerably the marine ecosystems which human-kind depends on.How to control the large-scale coastal reclamation is a great challenge in China.This paper presents an analytical framework and model to estimate the Total Allowable Area for Coastal Reclamation( TAACR) to provide scientific support for the implementation of a coastal reclamation restriction mechanism.Various benefits and costs,including the ecological and environmental costs of coastal reclamation,are systematically quantified in the framework.Model simulations are developed using data from West Sea of Xiamen.The results show that the TAACR in West Sea is 89.44 hm2at a discount rate of 4.5%.Area of West Sea must be maintained at a minimum of 44.52 km2so that the social well-being can be maximized.Under low discount rate,2%,the TAACR is zero.Even with high discount rate,8%,the optimal reclamation area is 157.97 hm2,about 35.83% of the total planned area.国家海洋公益资助项目(201105006); 国家社会科学基金资助项目(12BJ064); 福建省自然科学基金资助项目(No.2010J01360
