我国城市中心商业街改造建设的系统性思考

本文认为,我国城市中心商业街改造建设过程中存在一系列问题,如功能定位单一、交通不便、传统文化消逝、陷入“眼球经济”误区、盲目追求商街规模等。在深入分析这些问题的基础上,文章指出我国城市中心商业街的规划设计应注重交通规划、空间维度设计、定位与店铺组合、特色营造、景观设计及商业街管理制度及相关政策的完善与创新。     

我国城市商业街的发展战略构想

现代商业街是城市的精华，也是最具活力的公共空间。近年来，全国各地不断掀起商业街的新建和改造热潮。应当分析我国商业街的发展现状及存在的问题，借鉴西方国家商业街发展的成功经验，有针对性地选择城市商业街发展战略。     

图说广东

广州商业街的发展正面临很好的机遇。首先是城市更新改造速度加快。广州建设现代化大都市的进程促进了城市更新改造,也推动了商业街加快改造升级。其次是城市向中、外圈层发展,花都、番禺撤市改区,以及农村地区城市化发展,如撤镇转街、建设中心镇等,进一步扩大了商业街的发展空间。其三是政府高度重视商业街发展,把其作为城市空间的有机组成部分和商业发展的重要内容,对商业街发展给予了大力支持和积极引导,有利于商业街的改造和建设。其四是旅游业的发展对商业街的推动。2001年广州市社会消费品零售总额达到1675.06亿元,特色商业街起着重要的作用,是人们购     

商业街建设的战略、战术研究

商业街的建设可以从战略和战术两个方面去进行研究。战略即商业街的市场细分和市场定位问题，对商业街顾客进行合理的细分，并在目标顾客心目中树立一定的形象，这是建设整个商业街的大前提，也是贯穿整个建设过程和经营过程的根本指导思想。战术即在建商业街的过程中采取的具体方针，如到底是政府行为，还是企业行为；其管理模式到底应该怎样创新，是实行委托制、抽调制还是物业管理制；各种类型商业街的侧重点有何不同；业态、业种应该如何进行搭配；交通问题如何解决等等。

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。
