环境约束下转变我国外贸增长方式的机制与对策

中国对外贸易规模快速扩张的同时,主要出口行业的工业三废排放指标和主要出口口岸及地区的污染指标也随之上升,对资源和环境产生了负面影响。在当前资源环境约束下,对外贸易发展应该从环境输出走向环境修复,用循环经济理念指导生产经营,激励环境技术创新,实施战略性的环境措施和贸易措施,实现环境、贸易、可持续发展的三赢。     

Resettlement's impact on the domestic economy in lake restoration:case study of Poyang Lake region

The Chinese government started a lake restoration project in Poyang Lake region 10 years ago,and the expost monitor of the migrants' livelihoods was limited.This paper compares the composition difference of domestic income and domestic consumption between migration and non-migration villages in Poyang Lake region.The results show that the migrants' domestic income has increased in the last 10 years,which originated from the increasing trend of active and extensive rural labor migration,while the resettlement has not influenced the domestic income significantly.The resettlement stimulates younger farmers to work far away from home whose wages contribute nearly 80% of domestic income.The resettlement decreases their savings due to higher expenditure of daily life for those who work far away from home,and higher expenditure of food for those who stay at home,losing cultivated lands with irrigation system for vegetable.On the other hand,the increase of rural labor migration leads the migrants who stay at home to have access to more cultivated lands for rice and cotton,and the farmers also apply more fertilizer in the same cultivated land for more agriculture products.The resettlement makes most of migrants spend their savings on the improvement of their housing conditions due to not enough governmental financial support for new building.After the analysis,some factors that influence migrants' income and consumption are discussed.The paper may contribute to the building of Poyang Lake Ecological Economic Zone.     

高校基建修缮工程项目招标管理分析

基于投影寻踪聚类模型的区域经济可持续发展评价--以30个省1998～2011年数据为例

首先构建了一套涉及4个准则层、16个指标层的中国区域经济可持续发展评价指标体系,其次利用投影寻踪和聚类方法,对中国30个省（市、自治区）1998～2011年的经济可持续发展水平（多指标面板数据）进行评价,根据线性投影值进行聚类,并对中国省域经济可持续发展区域差异水平进行分析,在此基础上,对中西部地区经济可持续发展提出相应的建议。     

Prospects for Latin America and Caribbean Region in the Global Market for International Tourism: A Projection to the Year 2020

International tourism has become very important to several developing countries as a major source of foreign exchange earnings for their economic development. This article explores the potentials of countries of the Latin America and Caribbean region in the global market for international tourism up to the end of the next decade. This was achieved by analyzing past trends of international tourism in the region, and projecting these trends to the year 2020 using a combination of four different time‐series projection models evaluated by the mean absolute percentage error (MAPE). Results show that international tourism arrivals into the Latin America and Caribbean region would increase from 51.21 million in 2004 (end of observed period) to between 87.58 million and 100.03 million by the year 2020. The corresponding figures for international tourism receipts would go from US$34.11 billion in 2004 to between US$64.92 billion and US$75.79 billion by the year 2020. Socioeconomic impacts of these findings are given, and recommendations for marketing strategies, government public policies, and directions for future research are discussed.     

再生水补给的城市景观水体富营养化和生态防治

采用卫星定位方式,在S湖面选取五个观测点,对再生水补给的城市景观水体富营养化状况进行研究。结果显示,湖水中主要指标营养源CODcr.、TP、TN含量由原来的天然河水补给时9月份的峰值220、2.6、2.19（mg·L-1）分别下降到180、2.1、1.83（mg·L-1）,NH3-N含量由5月的峰值1.92（mg·L-1）下降到1.68（mg·L-1）;叶绿素和水体的PH也基本成良性发展态势,水体的富营养化得到一定的缓解。同时使用生态漂移岛为主的立体生态学复技术,对再生水补给的城市景观水体富营养化生态防治效果进行研究。研究结果表明,所选择的修复植物对水体中的富营养化指标物蓝藻和各种营养源的去除和控制率达到97%以上,实验点水质有较大改观,基本可避免城市景观水体因再生水补给带来的二次深度污染。     

南方离子型稀土矿的环境问题及生态重建途径

离子型稀土矿主要分布我国南方,含中、重稀土较多,具有很强的市场竞争力。但是在池浸、堆浸以及原地浸矿工艺开采过程中均出现了较严重的生态环境问题,对采矿废弃地进行人工生态重建是当前面临的紧迫任务。生态重建应从废弃地稳定化处理、土壤改良、生态系统的功能设计与植被的恢复等方面着手。环境工程开采模式、常态化环境监测以及相应政策与程序是生态重建的有力保障。     

Shares of the Rich and the Rest in the World Economy: Income Divergence Between Nations, 1820–2030

This paper analyses the forces determining per capita income levels of nations over the past millennium and the prospects to 2030. In the year 1000, Asian countries were in the lead. By 1820, per capita gross domestic product in Western Europe and the USA was twice the Asian average. The divergence had grown much bigger by 1950, but by the 1970s, several Asian countries – Japan, South Korea, Taiwan, Hong Kong, and Singapore – had achieved considerable catch-up. Since then, there has been a major surge in China and the beginning of a similar phenomenon in India. As a result, the Asian share of world income has risen steadily and, by 2030, will be fairly close to what it was in 1820. I conclude by comparing my projections for 2030 with those of Goldman Sachs, Perkins and Rawski, and Fogel.     

企业持续创新实现效能评价模型研究

基于企业持续创新实现机制,构建了企业持续创新实现模型,基于主成分投影法构建企业持续创新实现效能评价模型,并对云南省19家创新型企业的持续创新实现效能进行评价.在对评价结果进行深入分析后,发现制度结构要素是影响企业持续创新实现的最关键因素,完善的制度结构能改进和增强持续创新能力以及提高机遇捕捉能力.因而,企业要推动持续创新实现,必然要完善和改进产权制度、企业家管理制度、非正式制度等内部制度安排,同时,当地政府也要积极推进政策支持、营造公平竞争的市场环境.     

博物馆藏品修复质量控制研究

博物馆藏品修复具有不改变历史原貌和可逆性的要求。为了使博物馆藏品修复质量得到控制和提升,应从藏品自身状况、修复环境、修复工具与材料、修复人员与技术路线等要素人手,以全面质量管理理论为基础,开展标准化管理,合理设计修复方案、规范操作流程、以文件控制质量,从事先调查、环节设计、施工记录、事后总结几个方面提升修复质量。
