基于中国银行业和乳制品行业数据的“集中度—利润率”假说研究

在一定的条件下,产业集中度与利润率之间存在着某种程度的相关关系。在中国,银行业是垄断性较强的行业,而乳制品行业则是竞争性较强的行业,选取两个行业的具体数据进行回归分析,分析两个行业的集中度和利润率的关系,得出了完全不同的两种结论:银行业中行业利润率与行业集中度无明显的相关关系,而乳制品的行业利润率则与行业集中度成明显的正相关。由此可见,集中度与利润率正相关还是负相关取决于行业的特性,要因行业而异。     

FDI、产业聚集是否有助于国际竞争力提升*——基于中国制造业PVAR模型的实证研究

本文运用联合国商品贸易数据库2004-2013年共十年数据,对我国27个制造业国际竞争力、外商直接投资程度、产业集聚度进行测算,并利用静态面板回归和动态向量自回归PVAR模型对三者之间的内在作用关系进行实证对比分析。结果发现：（1）中国整体制造业国际竞争力稳步提升,但具备较强国际竞争力的还主要集中在劳动密集型行业,而中高技术行业是中国参与全球竞争形成优势最有潜力的行业;（2）我国引入外商直接投资占比变化不大,但其总额提升速度迅猛;（3）我国制造业的平均产业集聚程度呈上升趋势,但其大小程度及变化趋势在不同行业之间有着明显差别;（4）静态面板回归结果表明,FDI渗入程度越高,产业集聚程度越大,越有利于制造业国际竞争力的提升,此外,FDI与产业集聚间存在交互效应继而正向影响国际竞争力的提升;（5）向量自回归（PVAR）模型也显示FDI、产业聚集、国际竞争力间存在长期稳定的相关关系。     

转型期制造业地理集中影响因素的实证分析

在经济转型期,中国的制造业正在市场、政府、全球化等三股力量的共同作用下进行空间重组。本文在综述产业地理集中和集聚相关理论的基础上,对中国31个地区、制造业27个典型的行业的2005—2008年的数据进行面板回归分析。研究结果表明,在经济转型时期,在影响制造业地理集中的诸多因素中,产业关联度的高低对制造业地理集中的程度和水平影响最大。     

区际产业转移关联溢出与产业高质量发展——对电子设备制造业的实证检验

基于我国区际产业转移大背景,使用1999-2016内地年30个省市、27个二位数工业行业数据定量测度区际产业转移,选择产业关联较强的电子设备制造业为研究对象,使用投入产出法识别关联产业、测算其关联产业溢出,利用2004—2016年内地28个省市面板数据构建模型对关联产业溢出效应与电子设备制造业转移的关系、产业转移中的关联产业溢出与电子设备制造业高质量发展的关系分别进行了实证检验。研究发现：①2014年中国工业空间基尼系数出现拐点,总体工业由之前的分散转移转为新的集中转移,而电子设备制造业仍处在向中部地区和西南地区集聚的分散转移中;②电子设备制造业转移中的产业关联溢出效应确实存在,且促进了电子设备制造业生产效率的提高和产业高质量发展;③产业转移中第三产业关联溢出效应对电子设备制造业分散转移的作用高于工业,但工业的关联溢出对电子设备制造业生产效率提升的作用明显高于第三产业。     

企业进入与利润率的关系研究——来自汽车产业的实证检验

文章评述了与企业进入行为的影响因素相关的国内外文献,在此基础上以探讨企业进入与行业利润率的关系为切入点,运用VEC模型实证考察了近年来我国汽车产业高速发展过程中的企业进入和利润率变动.研究结果显示,我国汽车产业的企业进入与利润率之间只存在短期的均衡关系;并且在长期中,利润率变动不构成该产业中企业进入的主要原因.

产业集聚对浙江省制造业竞争力影响的实证分析

文章基于2005—2009年浙江省制造业30个行业的面板数据,通过建立固定效应变系数模型,定量分析产业集聚与产业竞争力之间的关系。研究发现,浙江大部分制造业的产业集聚会显著提升产业竞争力,但是也存在部分制造业的集聚对其竞争力产生负面影响,且其中多数为劳动密集型行业。为此,文章提出了差异化看待和发展产业集聚,进一步促进产业竞争力提升的政策建议。     

制造业空间集聚、外部经济性与企业生产效率研究

在一个地区的制造业某产业中,如果少数大企业在空间上高度集聚,那么,这种相对集中的区域经济结构可能会降低该地区制造业企业的生产效率。通过对中国橡胶与塑料制品制造业、金属制品业、专用设备制造业等三个制造业部门的研究,使用2001和2006年中国工业企业的微观数据进行实证检验,结果发现,区域产业集中度与制造业三部门企业的生产效率之间确实存在着显著的负向关系,虽然空间集聚产生的外部经济性在这个过程中也发挥了作用,但这种作用却是比较微弱的。     

产业集中度与企业创新绩效相关性研究——基于中国高技术产业的实证研究

对中国高技术产业的产业集中度与企业创新绩效的相关关系,实证结果表明：（1）从高技术产业总体来看,产业集中度与企业创新绩效存在长期与短期均衡关系,且二者均为正相关关系;（2）从高技术产业五个细分行业来看,产业集中度对各行业创新绩效的影响显示出较大差异,在医药制药业、航空航天器制造业中,产业集中度与企业创新绩效具有正相关关系,而电子及通讯设备制造业、电子计算机及办公设备制造业行业中,产业集中度对企业创新绩效呈现出负相关效应。

11月4日晚，申银万国与宏源证券宣布合并重组，合并后资产达1000亿，挤进行业前五，此次联姻将改变中国证券业的格局。本文研究证券行业的集中对行业的市场结构和盈利能力的重要影响。方法：本文运用绝对集中度指标，分析中国证券行业经历全球金融危机后(2008-2013)年的市场结构、垄断与盈利现状。结果：我国证券业市场集中度为由低集中产业向准中寡占产业过渡的阶段，市场集中度尚有较大的提升空间；行业利润率与二级市场集中度存在着显著的正相关关系。结论：提出中国证券行业市场结构的改善建议和如何提高盈利能力措施。     

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。
