十一五前三年我国单位国内生产总值二氧化碳排放下降12.2%,标志着温室气体排放得到有效控制,但同时控制能源活动温室气体排放政策仍然存在着定位不清、战略地位不明确、体制机制不健全等缺憾。2020年温室气体控制目标的提出和复杂的国际谈判形势也为下一步工作提出了新要求。因此,我国应根据形势变化,从十一五后期起对温室气体排放控制政策作出调整。  相似文献

该文从国外农业温室气体排放出发,总结了国外温室气体减排经验,继而从碳排放和非碳温室气体排放两个方面研究了中国农业温室气体排放途径和特点,并通过投入产出法对农业的隐含碳排放进行了测算,结果显示:2007年农业直接碳排放量为985.26万吨,直接碳排放强度0.1593吨/万元,隐含碳排放量为4452万吨,隐含碳排放量强度0.72吨/万元。在借鉴国外温室气体减排基础上,提出了适合我国国情的农业温室气体减排对策。  相似文献

对于特定年份某一城市低碳经济发展的成就进行评价,首先应当考察其温室气体排放总量和(总体)温室气体排放强度:更加细致一点,应当考察温室气体排放在三次产业和三次产业中主要行业的分布,以及三次产业和三次产业中主要行业的温室气体排放强度;在此基础上,可以进行城市问比较,以判断该城市在低碳经济发展国内外竞争格局中的位置。  相似文献

海洋在全球气候变化和碳循环过程中发挥着重要的作用,编制蓝碳生态系统温室气体排放/吸收清单对于保护和恢复蓝碳生态系统以及应对气候变化具有重要的意义。目前,针对红树林、海草床和滨海盐沼等温室气体清单编制还没有形成标准化的方法体系。通过开展蓝碳生态系统温室气体清单编制方法研究,构建出基于储量和通量法的蓝碳生态系统温室气体排放/吸收核算方法,设计出蓝碳生态系统温室气体清单表格。最后,结合我国国家温室气体清单编制现状,进一步指出我国蓝碳生态系统温室气体清单编制中的关键问题和未来研究方向,为纳入国家温室气体清单做好技术衔接。  相似文献

自2001入世以来,中国对外贸易的开放程度越来越高,伴随而来的是温室气体的排放总量的快速增长。文章以温室气体CO_2为例,借助2000-2013年中国贸易和CO_2排放量数据,采取协整分析方法系统分析了中国对外贸易与CO_2排放间的动态关系,研究结果表明:贸易开放与温室气体排放间互动效果明显,呈现为正向影响,且维持长期均衡稳定,这说明我国对外贸易开放程度是温室气体排放快速变化的原因之一,即贸易开放程度越高,CO_2排放量越大,在此基础上给出了促进我国对外贸易开放与资源环境保护良性互动的相关建议。  相似文献

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.  相似文献

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?  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

海岛地区产业演替及资源基础分析--以舟山群岛为例   总被引:2,自引:0,他引:2  
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。  相似文献

本文基于委托代理模型,从风险的视角研究企业治理结构对研发创新能力的影响。本文构建了一个包含创新活动的委托代理模型进行理论分析,利用动态DEA 模型测算创新能力,并使用2015-2018年我国上市制造业企业数据进行实证检验。实证部分检验了理论结论:委托代理问题不利于企业提升研发创新能力,且客观风险和主观风险厌恶会加剧该负面影响。基于此,本文认为上市企业应根据企业自身研发活动特点有针对性地改善企业治理结构,提出了适当延长代理人任期、推动股权激励计划、提升代理人的风险承担能力等建议。  相似文献
