区域水资源生态环境现状及优化策略研究

基于社会经济视角,对区域水资源生态环境现状及优化策略问题进行研究,在对社会经济与水资源生态环境系统反馈机制分析的基础上,利用环境库兹涅茨曲线,以湖北省为例研究了经济增长与水资源生态环境的关系,认为社会经济发展对区域水资源生态环境影响显著,应该从技术与产业结构、环境政策、市场机制和污水处理投资4个方面加以优化。     

区域物流业可持续发展评价指标体系构建与实证研究

基于科学性、系统性、客观性和可操作性原则,以可持续发展理论为指导,以资料的可获取性为前提,以既能体现现有区域物流业可持续发展的能力,又能反映未来的发展潜力为目标,着重从社会经济发展对物流业的支撑、物流经济发展状况、物流经济发展对生态环境的影响三个方面建立21个区域物流业可持续发展评价指标。运用因子分析方法,把这21个指标划分为物流经济规模、物流经济效率、物流业对环境影响3个公共因子,3个公共因子累积解释86.935%的变异量。同时,对全国30个省直辖市自治区物流业可持续发展情况进行评价,评价结果基本符合实际。希望能为中国物流业可持续发展提供借鉴。     

山西省水资源压力评价——基于投影寻踪法

水资源是经济发展的基础资源,水资源压力的大小对区域经济发展布局的安排、发展模式的选择起着决定性作用。以投影寻踪理论为基础,选取了体现水资源禀赋压力、空间组合压力、开发利用压力的12个指标,构建了水资源压力评价模型,对山西省水资源压力进行了综合评价。评价结果表明,造成水资源压力的显著影响因素为取水结构、用水结构和水资源生产效率,其次为水资源与社会经济要素的匹配性。在此基础上对山西省未来发展提出相应建议。     

中原经济区县域交通优势度与区域经济空间耦合

从路网密度、可达性和区位优势度三方面构建交通优势度评价指标体系对中原经济区2008年县域交通优势度进行评价与比较;并在中原经济区县域经济发展水平评价的基础上,对交通优势度与县域经济的耦合及协调度进行测度,并进行耦合—协调类型区划分。中原经济区交通优势度区域差异突出,呈现出以郑州为中心向外围递减的圈层状空间格局;县域经济水平西北部高于东南部,山区资源县高于平原农业县;虽然各县市交通优势度与经济发展水平耦合度均较高,但大多数县市处于中度协调或勉强协调状态;绝大多数县市交通超前发展,仅西北部边缘县市交通对区域发展的支撑能力不足;中原经济区应充分依托现有的交通支撑优势,加快推进县域经济发展,实现经济与交通的协调发展。     

水资源约束下的黑龙江省东部煤电化基地发展研究

水是经济发展的基础性资源,并日益成为经济发展的重要约束因素。探讨了水资源与经济工业发展的一般关系。着眼于黑龙江省东部煤电化基地规划,结合基地水资源状况和经济发展状况,探讨了水资源对煤电化基地建设的制约:供需矛盾突出;项目建设与水资源分布不对称;水资源相对不足,部分区域水资源开发即将进入饱和状态;项目建设分散引致水源供给困难;污水治理不力。在此基础上,提出了应科学界定区域水资源承载力和开发强度、加大水利建设投入、优化煤电化项目布局、提倡节水和加强水污染治理等建议。     

基于GIS的湖南省生态环境综合评价研究

应用GIS技术与层次分析法，从自然环境、灾害状况、环境污染和社会经济四个方面对湖南省的生态环境进行了定量综合评价和空间格局分析，并根据评价结果将湖南省生态环境划分为五个级别。研究表明，湖南省生态环境综合状况基本上由东向西逐渐变差，但局部区域有差异，且自然环境与社会经济状况的空间分布大体吻合。说明自然环境条件对湖南省生态环境的空间分异起主要作用，但灾害、经济发展和环境污染等因素也在一定程度上影响了生态环境的空间格局。     

长株潭城市群水资源与经济发展要素的时空匹配

水资源是影响社会经济发展、战略布局等城镇化重大措施实施的资源制约因素。文章以长株潭城市群2009—2015年水资源分布、水资源配置、经济社会发展等相关数据为基础,通过计算区域水资源与人口、土地面积、GDP等经济发展要素的基尼系数,对水资源分布、配置及其与经济发展要素匹配关系的演变规律进行研究。结果表明:长株潭城市群水资源分布和配置与人口、土地面积处于高度匹配状态,与GDP分布处于比较匹配状态;但在县域层面,水资源与经济要素的洛伦兹曲线反映出两者存在空间差异性的特点。通过计算研究区域水资源—经济发展要素的不平衡指数,进一步探讨了区域水资源分布、配置与经济发展要素在空间上的协调格局,揭示其主要的影响地区。在此基础上,提出了相应的措施建议,以期为协调研究区域水资源与经济的发展,优化调控水资源的配置提供参考。

A Rich Vein for “Reality Mining”北大核心CSSCISSCI

Arik Hesseldahl In the aftermath of the September 11 attacks, U.S. officials quickly turned their attention to other potential targets, including California's Golden Gate Bridge. What would happen if terrorists took down the bridge between San Francisco and Marin County? How much of the region would be affected and for how long?     

John Stuart Mill's Theory Of Justice

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.

John Stuart Mill's Theories of Wealth and Income Distribution

Although he was much influenced by David Ricardo when he wrote the classical part of his Principles , John Stuart Mill was not a Ricardian when he penned his theories of wealth and distribution. They are based on a triple foundation. First, a belief that economics is a moral discipline. Second a theory of custom-driven human behavior. Third, an empirically formed conviction that the institutions of state, education and business cooperate to structure the distribution of income. On the basis of these presuppositions, Mill formulated 1) an institutional theory of the formation of human and non-human wealth and 2) an even more institutional theory of distribution demonstrating how the aforementioned institutions malignantly skew the distribution of income to the advantage of the propertied classes and to the extreme disadvantage of the working class. As a social economist, Mill recommended institutional reforms designed to eradicate the poverty of the working class.     

Toward a Phylogenetic Reconstruction of Organizational Life

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields such as organizational science, management science and economics and have long recognized that classification offers an approach for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities). However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity. This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics) are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic classification approach for inferring and representing the historical relationships underpinning organizational diversity. This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently, this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification of organizational diversity.     

Information infrastructure: Who builds broadband networks?

This paper examines the essential difference between the U.S. and Japan, when one considers information infrastructure. There are seven perception gaps between the U.S. and Japan concerning Information Infrastructure policies. These gaps must be understood in order to compare the countries' governmental policies in this area. In looking at the present circumstances, the essential question to answer concerns who is to build, own and operate the network(s) of the infrastructure. Liberalization is certain to be a central factor in the ongoing telecommunications debates. Now that customers have had a taste of the liberalized market-place, the movement toward more open markets will be difficult to stop. When considering options, it is necessary to pay close attention to standardized network access and the increasingly important role software plays. These issues are causing us to take a new approach to the traditional role played by regulators. They also force a closer look at the appropriate structure of utility companies. This paper addresses the above issues in hopes of stimulating dialog on the new telecommunications infrastructure paradigm.

海岛地区产业演替及资源基础分析--以舟山群岛为例

改革开放以来,舟山市产业构成发生了显著变化,其经济发展过程可以划分为三个阶段。1992年前,是以产业结构渔业占绝对地位的单一结构阶段;1993—1998年,以旅游业为主的第三产业快速发展阶段;上世纪末以来,又进入了新一轮的经济发展时期,即工业产值比重快速增加阶段。根据海岛的自然资源基础和特点,在新世纪的经济发展过程中,舟山市应定位为生态型的港口旅游城市。以港口及临港工业为主导,以海岛旅游和海洋经济为特色,大力发展第二产业和第三产业。海岛地区的主导产业应体现海岛资源优势及区位优势,以集群性环保型产业为主。同时由于海岛地区淡水资源缺乏,主导产业也应着重选择低耗水型产业。
