创新型产业集群对国家高新区集聚效应影响研究

为评估创新型产业集群对国家高新区集聚效应的影响作用,文章采用双重差分法进行国家高新区和创新型产业集群的准自然实验.结果 表明,创新型产业集群集聚更多资源要素,能够提高国家高新区集聚效应.创新型产业集群对高新区集聚效应的提高程度,呈现显著空间差异:东部地区政策效果最为显著,仅略高于西部地区,而中部地区效果最不明显.需通过强化创新型产业集群创新集聚功能,提升高新区创新载体功能,积极发挥产业集群培育的外部效应.

创新型产业集群是否提升了国家高新区创新效率？

因产业集聚转型的迫切性及产业集群创设先天优势,创新型产业集群试点在国家高新区开展,并成为国家高新区推动战略性新兴产业发展的重要途径。以创新型产业集群建设为准自然实验,运用双重差分法评估创新型产业集群对高新区创新效率的提升作用。结论表明:与对照组相比,创新型产业集群建设显著提高了实验组的创新效率;相比东部和东北地区,创新型产业集群对中部和西部地区的高新区创新效率影响更为显著。未来可通过在中西部地区扩大政策实施范围,提升整体区域产业创新能力。

国家高新区“以集群促发展”政策是否提升了城市创新水平——兼论创新集群“中心—外围”结构的技术互补效应

本文根据2011年科技部启动实施的“创新型产业集群建设工程”来设计准自然实验，采用2007—2016年中国城市层面的独特数据，实证考察国家高新区“以集群促发展”政策对所在城市创新水平的影响。结果发现，国家高新区实施创新型产业集群政策显著提升了城市创新水平，且经过系列安慰剂检验和稳健性检验后上述基准结论依然成立。政策差异化视角的研究表明，创新型产业集群试点培育政策对城市创新的激励效应明显弱于试点建设政策。机制分析结果表明，国家高新区实施创新集群政策通过政策效应、协同集聚效应和信号传递效应三种机制影响城市创新。进一步讨论发现，创新型产业集群政策具有明显的“中心—外围”结构技术互补效应。本文的研究对国家高新区制度设计及产业政策体系变革具有重要的参考价值。     

国家高新区对外贸易、高新技术企业占比影响创新效率的实证研究

加快推进国家高新区发展，是提高创新竞争力、实现经济高质量发展的重要途径。运用超效率DEA模型测算2013-2017年国家高新区创新效率，利用面板数据模型考察对外贸易、高新技术企业发展与创新效率的相关关系及地区差异。研究表明：我国东部地区国家高新区创新效率相对较高，中部地区、西部地区、东北地区高新区创新效率差异明显；国家高新区对外贸易、高新技术企业占比对高新区创新效率提升具有显著正向促进作用，且存在显著正向时滞效应；国家高新区对外贸易、高新技术企业占比对国家高新区创新效率的影响存在地区差异。新时代全面提升国家高新区创新效率，应以高新技术企业为主体，以进一步扩大开放为路径，注重开放贸易、高新技术企业发展相关政策的阶段性与针对性调整。     

国家高新区设立对属地省域绿色创新水平的驱动效应评估

立足于探讨国家高新区设立对属地省域绿色创新水平的实际驱动效应。首先,从理论层面揭示了高新区设立驱动绿色创新水平提升的3个作用机理,即集聚驱动、结构驱动和规模约束驱动;其次,构建了衡量区域绿色创新水平的评价指标体系,在此基础上,综合应用基于非期望产出的SBM-DEA模型和核密度估计,对中国区域绿色创新水平的基本格局及区域差异演变特征进行探讨。结果表明,中国区域绿色创新效率呈波动上升态势,但存在明显的空间差异,核密度估计结果也显示中国绿色创新水平省域差异日益扩大,马太效应日趋明显;最后,以2006-2015年中国内地30个省市面板数据为例,采用面板Tobit模型验证高新区设立对区域绿色创新水平的影响。实证结果显示,国家高新区的设立对区域绿色创新水平具有显著驱动效应,但高新区发挥实际作用还依赖于经济基础,进一步分析表明,高新区设立对东部省市绿色创新水平的驱动效果显著,而对中西部地区没有明显的驱动作用,最后据此提出相应启示与对策。     

基于产业集群的高新区发展导向研究

产业集群的发展是高新区实现可持续发展、提升高新技术产业竞争力的重要途径。产业集群的形成有自身的机制和规律,高新区现有的产业集聚是政府主导的结果,这种模式的产业集群向高级阶段演进必须通过产业集群的自组织机制来完成。高新技术产业集群支持要素是高新区产业集群形成和发展的基础,在要素完善的基础上,通过要素流动与竞合、技术创新、根植机制等的协同作用,可以促进产业集群自组织机制的形成。重视各要素的培育和完善,是高新区实施产业集群导向的主要手段和策略。     

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。
