国际贸易理论的新发展与东亚实践

企业活动的国际化在东亚日渐形成的国际分工体制中是个极其重要的关键因素,探索其为何要走向国际化,对我国参与国际分工、特别是积极实施"走出去"战略,显然具有适时和现实的实践意义.在当前分工最活跃的东亚地区,这些理论的新发展正在被实践所证实.

Industry-region Position and Economic Performance of Travel and Tourism Service Industry: An Agglomeration Perspective

Numerous studies have attempted to examine industry performance from an agglomeration perspective. However, many are still focused on the manufacturing sector. This study examines the travel and tourism service industry's economic position using an agglomeration perspective and whether this relates to its economic performance. This study discovered that, apart from being related to its intra-region position relative to other industries within the region, the economic performance of an industry in a region is also related to its intra-industry position relative to other distributive regions within the industry and to its national geographical concentration. A more significant finding is that regardless of either the intra-industry or intra-region position of the industry in a region, enhancing agglomeration not only increases competition and profit erosion but also improves labour productivity. For employment creation, it is more effective to develop an industry with more uniform national geographical distribution.     

Sectoral Productivity,Density and Agglomeration in the Wider Europe

Abstract

We then test this model using panel data for five sectors on regional-level data for 27 EU Member States. Our results for the aggregate economy confirm previous estimates. For our full sample of countries the sectoral-level results also indicate significant agglomeration effects. Considering differences in the extent of agglomeration effects between new and old EU Member States, however, leads to the conclusion that agglomeration effects tend to be stronger at both the aggregate and the sectoral level for new Member States.

Productivité sectorielle, densité et agglomération dans l'Europe élargie

RÉSUMÉ?Nous testons ensuite ce modèle en utilisant des données de panel pour cinq secteurs à l'échelon régional dans 27 états membres de l'UE. Les résultats que nous obtenons pour l'économie dans son ensemble confirment les estimations précédent. Pour notre échantillon complet de pays, les résultats au niveau sectoriel font état d'importants effets d'agglomération. Si, toutefois, l'on tient compte des différences quant à l'étendue des effets d'agglomération entre nouveaux et anciens états membres de l'UE, on en conclut que les effets d'agglomération ont tendance à être plus prononcés à l'échelon global et à l'échelon sectoriel chez les nouveaux états membres.

Productividad sectoral, densidad y aglomeración en la Europa más amplia

RÉSUMÉN?A continuación, ensayamos este modelo utilizando datos de panel para cinco sectores aplicables a datos de nivel regional sobre 27 estados miembros de la UE. Nuestros resultados en relación con la economía agregada confirman las estimaciones anterior. Con respecto a nuestra muestra completa de países, los resultados de nivel sectoral también indican efectos significativos de la aglomeración. No obstante, la consideración de diferencias en la extensión de los efectos de la aglomeración entre nuevos y antiguos estados miembros de la UE, lleva a la conclusión de que los efectos de la aglomeración tienden a ser más pronunciados en los nuevos estados miembros, tanto a nivel agregado como sectoral.

     

Strategic Location Behaviour: The Case of Japanese Investments in Europe

SUMMARY

We address the question of competition within the location choices of firms. In a framework of agglomeration effects, both spatial and temporal dimensions of the firms' decisions are studied. We show that the competition consequences of preemptive move and optimal time of entry can interfere with the geographical decisions. Our results contrast with those of agglomeration economics models which generally provide extreme results of mono-location. The equilibria described here tend to demonstrate that the relation between competition strength and spatial differentiation remains pertinent in a context of agglomeration economies. A conditional logit empirical study analyses the geographical choice of Japanese firms in Europe. Agglomeration variables, public policies and labour market determinants are tested, highlighting the existence of temporal and spatial proximity in the behaviour of firms. The competition conditions experienced by firms of each specific sector also appear to be important in the location decision of Japanese investors.     

会展业集聚的系统动力学研究

产业集聚的影响已经引起国内外的学者的重视,会展业作为一个综合性产业,能同时带动多个经济面的发展。本文以系统动力学理论为基础,结合会展业产业集群的正负反馈特征,对会展业与基础产业、产业政策等因果关系进行了探讨。通过会展产业集聚效应的研究,利用Vensim构建系统动力学模型,分析制约会展产业集聚效应发挥的主要因素,并以上海地区会展业为例,运行模型,结果表明,模型对产业集聚效应的实际演化过程具有较高的拟合程度,并能够为区域经济管理提供有效的决策支持。     

郑州区域性金融中心建设的问题与对策

金融业日益成为经济发展的主要推动力,郑州区域性金融中心建设也是推动郑州乃至河南发展的重要手段。郑州已具备建设区域性金融中心的经济基础和金融基础,但建设中还存在诸如金融业态不完善、资本市场发育不良、金融生态环境不良等诸多问题,因此郑州区域性金融中心建设还要在以下几方面做出努力:健全金融机构体系,建设金融后台服务中心,提升期货业影响力,健全资本市场。     

文化产业、创意经济与和谐社会

随着社会转型的发生,促进文化产业的发展正在成为推动经济增长的重要途径.而文化产业自身的空间集聚特征,使借助市场力量的城市再开发和通过规划培育创意经济成为塑造创新文化气氛、营销城市的重要政策工具.然而全球化的宏观背景不仅使这种以营造独特和多元地方文化为初衷的努力往往以千篇一律的形体景观和单调社会构成的结果出现,而且通常也是以发展中国家劳动力和社会弱势群体的利益遭受侵害为代价的.因此,在中国,成功发展文化产业不单需要研究如何将针对具体地方特点的市场和规划手段相互结合,以实现真正的创新,更需要警醒地认识到文化产业发展过程中的社会福利效应.从而达到建设和谐社会的根本目标.     

The effects of agglomeration externalities on urban green total-factor productivity in China

For China's urban industrial layout and green development, determining which types of agglomeration externalities are most advantageous to the rise of green total-factor productivity has both theoretical and practical relevance. This research experimentally studies the effects of three types of agglomeration externalities on urban green total-factor productivity using the data of 285 Chinese cities from 2003 to 2018. The findings demonstrate that urban green total-factor output is rising, albeit with certain differences during different time periods. Both the Jacobs externality and the Porter externality are favorable for increasing urban green total-factor production when all cities are evaluated together, although the latter has a stronger promoting influence. The effect of the Marshall-Arrow-Romer externality, on the other hand, is not significant. Furthermore, these effects also depend on the stage of economic development and population size.     

青海藏毯企业集群研究

全球化加剧了市场竞争,集群作为提升企业竞争力的强有力的重要手段,已成为国内各地区竞相培育的核心竞争优势之一。长期以来,国内关于企业集聚和企业集群的概念一直混淆不清,相互替代使用。本文从产业集群的内涵和本质加以区分,并对产业集群的形成条件和演进的主要影响因素进行分析,认为青海藏毯企业是集聚而非集群,要加快青海藏毯企业由集聚到集群,必须建立相应的助推机制,并强调青海地方政府的扶持对藏毯企业集群的形成起着关键性作用。
