转向贸易强国的途径

中国已成为世界贸易大国，但还不是贸易强国，出口产品附加值低、效益不高，需要提高我国对外贸易的竞争力和综合效益，通过科技兴贸，实施品牌战略，大力发展服务贸易，加快从贸易大国向贸易强国转变。     

贸易大国与贸易强国的评判及经验研究

为实现中国对外贸易从贸易大国向贸易强国转变,首先应明确贸易强国的内涵与目标.笔者从主体、内容和市场等方面构建贸易强国(地区)的指标体系,将外贸增长方式转变成目标内涵并具体化,通过因子分析法构建贸易大国和贸易强国的判别标准,再利用聚类分析法判别中国在贸易强国标准下的层次和地位,最后提出中国由贸易大国向贸易强国转变的建议.

中国成为钢铁强国所涉及的支撑性要素

中国是钢铁大国，但还不是钢铁强国，这已为中国钢铁产业各界人士所认可。但同时要看到中国成为钢铁强国已是大势所趋。目前的问题是中国要成为什么样的钢铁强国，政府、钢铁产业、钢铁企业作为钢铁强国的共同创建主体需要做什么，中国成为钢铁强国对中国钢铁产业、钢铁市场及钢铁企业意味着要努力去改变什么。     

对中国体育大国与体育强国的质疑

自北京奥运会成功举办之后,国家进一步高度重视中国的群众体育事业,并提出中国要由体育大国向体育强国迈进。由此,可以看出国家认为中国已经成为体育大国。然而,中国真的是体育大国吗？中国还离体育强国有多少距离？与真正的体育强国之间还有多少差距？这些都是当前需要质疑的问题。     

中日蔬菜贸易流量与贸易前景——基于引力模型的研究

由于中国蔬菜产业的迅猛发展,国内市场早已出现饱和状态,蔬菜产品出口势头强劲,中国已经成为世界蔬菜生产和出口的第一大国。虽然中国蔬菜出口的绝对量很大,但与其他蔬菜出口大国相比还有很大差距,因此蔬菜产业出口还有很大提升空间。日本作为中国蔬菜出口的第一大市场,吸收了中国蔬菜出口量的40%左右。因此,研究中日两国的蔬菜贸易可以为双边蔬菜贸易发展提供借鉴和指导。     

郑在浩：第三者看中国崛起

具体在什么时候中国会成为世界第一强国，是谁都不敢回答的问题。但是这个趋势好像已定下来了，几乎不会变。21世纪最大的话题无疑是中国的崛起。一般来说，国际政治理论多半是采取强国和大国的观点来解释现状的。     

中国如何从贸易大国走向贸易强国

经济危机以来，中国的以外贸带动经济增长模式受到了质疑，多数观点认为这种模式应该伴随着美国的消费增长模式一起走到尽头。实际上，各国的比较优势和竞争优势没有发生改变，中国应该继续走贸易强国之路。文章分析了中国从贸易大国走向贸易强国的必要性和可行性，并且提出了制定贸易强国对策的原则和具体对策。     

创新、国际贸易与经济贸易强国

中国已经成为经济贸易大国，但从国际贸易角度上看中国距离经济贸易强国还有很大差距。我国提出建设创新型社会的决策，以实现我国向经济贸易强国的转变，费尔普斯2004年在人民大学举行的学术论坛上也指出创新才是中国经济发展的最佳选择路径。     

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。
