循环经济现状分析及对策研究

自从循环经济理念提出以来,各个国家和地区大力发展,我国不断进行循环经济探索与实践,取得了明显的成绩,但依然与发达国家之间差距明显,循环经济实践依然存在很多问题.我国经济发展方式依然粗放,仍以传统的“高消耗、低产出、高污染”的生产方式来维持我国经济的高速增长,环境问题日益突出,已成为制约经济社会发展的瓶颈问题,另外,我国人均资源量低,仅占世界平均水平的1/4,然而资源的利用效率却很低下,立足现实国情,分析发展形势,如何更好的发展循环经济,推进我国经济增长方式从粗放型向集约型转变,具有非常重要意义.     

资源约束与能源发展战略的重要选择——也谈大力发展循环经济的风力发电

资源约束矛盾是目前我国经济社会发展面临的迫切需要解决的问题，而其中的电力紧张在区域范围内甚至成为发展的瓶颈。缓解资源约束、建设节约型社会是事关我国可持续发展的重要战略抉择，发展循环经济是一项重要的举措，而从我国的现有资源状况出发，大力发展风力发电则是一种符合循环经济又切实可行的项目选择。     

转变资源“透支”型增长方式的战略选择

以高消耗、高污染、低产出为特征的资源“透支”型增长方式已成为制约我国实现经济持续稳定健康发展的瓶颈，必须走一条科学发展的路子。循环经济是“资源→产品→废弃物→再生资源”的闭路反馈式资源利用过程，是当前最先进的经济增长模式。要从统筹规划、立法保障和技术支撑等方面努力，实现增长方式的根本转变。     

制约我国循环经济发展的因素与西方国家推进机制之借鉴

循环经济是一种基于人与自然和谐发展哲学理念的可持续发展模式.它为解决人类社会后工业经济发展中出现的人与自然的尖锐矛盾找到了一条可行的途径.我国经济增长面临着非常严峻的资源瓶颈约束.打破资源瓶颈制约的途径是必须积极发展循环经济.本文分析了我国发展循环经济面临的制约因素,总结发达国家发展循环经济的经验,探讨了我国发展循环经济的推进机制.     

燃煤电厂建立循环经济模式的对策

循环经济的本质在于不断追求用最小的环境成本和资源成本获得最大的发展效益，以实现可持续发展。本文在分析我国燃煤电厂构建循环经济模式的必要性和可能性的基础上。提出了燃煤电厂克服技术与制度瓶颈、发展循环经济模式的相关对策。     

关于我国实现循环经济与可持续发展的思考

改革开放以来，我国经济进入了高速发展阶段，用短短几十年时间走完了发达国家上百年的路程，以至生态和环境遭受了严重破坏，资源和环境的承载力已难以支撑经济的高速增长，成为经济增长的瓶颈。所以我们必须加快转变经济增长方式，大力发展循环经济，实现资源的高效利用和循环利用，对于我们这样一个资源和环境容量有限的人口大国，就具有重要的现实意义。     

试论发展循环经济在转变经济发展方式中的重要意义

环境资源日趋紧张,循环经济已成为当前世界上先进的经济模式,也是我国实现可持续发展的必然选择。文章从我国循环经济发展的现状分析入手,论述了发展循环经济在转变经济发展方式以及促进人与自然和谐发展的重要意义。     

发展循环经济缓解矿产资源对经济发展的约束

我国经济增长所需主要工业原料和能源均来自矿产资源,资源约束目前已经成为制约我国经济持续高速发展的一大瓶颈。在了解、分析我国矿产资源利用现状的基础上,探讨了矿产资源及相关产业与我国经济发展的关系,认为大力发展循环经济、提高资源利用效率是缓解我国矿产资源约束的有力手段。     

我国石化产业必须走循环经济发展之路

环境污染和资源制约决定走循环经济之路是石化产业发展的必然选择，集约化程度低、科技含量不高及政策措施不到位是我国石化产业发展循环经济的主要问题与障碍。我国石化产业发展循环经济必须全面推进企业清洁生产；构建产业生态工业园区；发展技术含量高的产品；提高资源及能源的利用效率；营造发展循环经济的外部环境。     

论循环经济发展的必然性

循环经济本质是一种生态经济，是把清洁生产和废弃物的综合利用融为 一体的经济。随着资源环境问题的加剧，发展循环经济已成为时代的要求，变得日益紧迫。那么，如何发展我国循环经济？本文提出了相关的建议。     

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.     

中国养活自己能力的长期预测:技术和政策分析

中国拥有世界五分之一强的人口 ,收入又在迅速增长。因此 ,国际上很自然地会考虑或推测她在今后的几十年是否有能力养活自己。中国的人口预计将从 2 0 0 0年的 1 2 8亿增长到 2 0 2 0年的 1 4 6亿 ,和 2 0 3 0年的 1 4 9亿。与此同时 ,人均收入的增长将导致对家畜和鱼类产品更大的需求 ,因而对饲料的需求也将有很大的增长     

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。     

风险视角下企业治理结构和研发创新——基于委托代理模型的研究

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。
