STUDY ON THE DEVELOPMENT STRATEGY OF DEHUA CERAMICS INDUSTRY
内容摘要日用陶瓷工业是福建省德化县的支柱产业。改革开放以来,德化陶瓷业随着中国日用陶瓷工业一起快速成长,德化已成为当代中国十大主要陶瓷产区之一,并且是国内最大的工艺瓷生产和出口基地,产品远销世界160多个国家和地区。从德化日用陶瓷业的发展历程中也可看出,我国陶瓷产业大而不强,产量虽高但整体档次较低。德化陶瓷出口虽然具有较强的价格竞争优势,但产品附加值少。此外,还存在产业结构不合理、产品开发研究薄弱、缺乏强势品牌、企业管理方式落后等问题。进入21世纪,在经济运作市场化与企业经营全球化的趋势影响下,在我国加入WTO后经济发展的机遇与挑战并存的形势下,德化陶瓷业如何利用国际陶瓷产业结构重新布局与调整...ABSTRACTTableware ceramics is the dominate industry in Dehua county, Fujian province. With the opening and reformation of China, Dehua tableware ceramics industry and the total tableware ceramics industry of China developed very rapidly.

A Study on the Imbalance of the Provision of Chinese Public Goods in the Process of Development
公共品反映了社会的共同需要,也代表着社会的共同利益,是历史发展中的一种经济现象。改革开放以后,我国经济实力有了极大的提高。然而,在高速发展的进程中也产生并累积了一些缺陷,特别是城乡之间、地区之间的经济社会发展存在不协调。其中,公共品供给失衡是一个主要的不协调因素。本文试从多维视角考察我国公共品供给失衡的缘由与失衡机制,结合发展观的演化和历史与经济社会发展进程,探求公共品供给失衡的解决方法,并构建一个缓解失衡的基本框架。 在对与公共品供给失衡相关的理论与文献进行梳理的基础上,本文探讨社会发展与公共品供给之间的相互影响,认为公共品供给失衡将延滞社会发展进程。研究采集了大量的材料与数据对我国公共品...Public Goods reflects the common needs of the society, and represents the common interests of the society too. It is a kind of economic phenomenon in the process of development in history. After the reform and opening-up, our country’s economic strength has made great improvement. However, some defects have produced and accumulated in the course of high-speed development. Especially, the social ec...学位:经济学博士院系专业:经济学院经济研究所_政治经济学学号:2902007015393
地方政府财政支出效率与影响因素分析——以福建省为例的实证研究
利用数据包络分析法(dEA)与固定效应面板回归模型的两阶段分析方法,对福建省辖区内九个地区的财政支出效率进行核算,研究发现福建省各地的财政支出效率是比较高的,但还未达最优效率水平。教育水平对支出效率的影响显著为正,财富水平对支出效率的作用是显著为负的。“预算内财政支出/gdP“和政府规模对支出效率的影响显著为负,但是人均基本建设支出对支出效率的作用虽是负效应,却呈不显著。建议构建一套完善的财政支出效益评价体系,引导财政资金在各部门、各领域之间进行合理配置,提高财政资金在各部门、各领域的使用效率
试论我国城市和谐发展的因素取向
本文从约翰·弗里德曼的规划理论切入,探讨我国城市和谐发展问题,指出城市人口的组成是多层次的,收入分化是当前我国城市社会面临的最大问题。城市是公共政策的结果,应关注人的发展权,保障城市社会公平。城市外生型发展的因素是不确定的,城市的长期竞争力与可持续发展要依赖于城市内生资源优势的挖掘和发挥,保持和提升城市创造财富的资源领域的质量
Pollution History and Sources of Organotin Compounds in Aquaculture Water of Tong'an Bay,Xiamen
通过对厦门同安湾养殖海域沉积物柱样(柱深180 CM)中6种不同形态有机锡化合物(丁基锡和苯基锡)的gC-fPd定量分析测定,并结合210Pb同位素定年,追溯了该地区近几十年来有机锡污染的沉积历史(1931~2007年).研究表明,该海域从20世纪50年代(0~80 CM段)开始出现有机锡化合物污染,总有机锡化合物的含量(干重)在3.43~69.6 ng.g-1之间,平均值为15.0 ng.g-1,其中丁基锡化合物含量分布范围为2.51~68.8 ng.g-1(平均值14.6 ng.g-1),约占总有机锡含量的97.4%,降解产物以一丁基锡为主要形态;苯基锡仅占2.58%.与世界其他港口海湾沉积物中有机锡的污染相比,厦门同安湾丁基锡化合物的污染处于较低水平.该养殖区域以丁基锡污染为主,推测来源于早期的船舶防污漆,苯基锡的少量检出可能来源于船舶防护漆使用时的副产品.同时,该海域沉积物中有机锡化合物的含量和组成分布特征,表明其可能受到水动力条件和海上建筑、船舶防污漆泄漏的双重影响,而海水养殖造成的影响也不容忽视.有机锡化合物的沉积历史分析表明,柱样中有机锡化合物含量的垂直分布特征,较好重现了该地域有机锡化合物的使用历史和在一定程度上反映了同安湾海域功能区划的改变.Six organotin compounds(OTs) in core sediment collected from aquaculture water of Tong'an Bay,Xiamen were detected by GC-FPD.Based on 210Pb-dating data,the pollution history(from 1931 to 2007) of OTs in this area was reconstructed and their possible sources were also discussed.The results showed that the inputs of organotin compounds in this sea area began from 1950's(0-80 cm).The vertical concentrations of OTs ranged from 3.43-69.6 ng·g-1(dry weight),the mean value was 15.0 ng·g-1.Butyltins concentrations ranged from 2.51-68.8 ng·g-1 and the average concentration was 14.6 ng·g-1 which accounted for 97.4% of total OTs,while phenyltins just accounted for 2.58%.It is indicated that the aquaculture waters of Tong'an Bay were mainly contaminated by butyltin compounds,inferring that they may come from the early antifouling paint of ships.The distributions of OTs concentrations and compositions may be related to the complex influence of the hydrodynamic conditions,antifouling paint leakages from ships and marine structures,and aquaculture.Compared to the other harbors and bays,the magnitude of OTs pollution in the sediment from Tong'an Bay was at the low midpoint on a global scale.Moreover,the sedimentary history showed that,vertical OTs distributions were in good agreement with the usage history of organotin compounds as antifouling paints and the changes of the major function regionalization in the surrounding area.国家自然科学基金项目(20777060);国家海洋局海洋三所基本科研业务费专项(海三科2007019
