The impact of language borders on the spatial decay of agglomeration and competition spillovers

There is now strong evidence that “soft” institutions are interrelated with the working of the economy. For example, in a geographical setting there is evidence that language borders affect interpersonal relationships, but there is no equivalent evidence regarding the effects of language borders on agglomeration or competition spillovers. This paper examines whether language affects the geographical extension of agglomeration and competition spillovers by observing the geography of employment patterns in a linguistically discontinuous setting. Our findings, for the first time, provide empirical evidence that language borders shape the distance decay of competition spillovers, independent of governance, and institutional issues.     

The territorial dynamics of innovation: a Europe United States comparative analysis

The United States and European Union differ significantly interms of their innovative capacity: the former have been ableto gain and maintain world leadership in innovation and technologywhile the latter continues to lag. Notwithstanding the magnitudeof this innovation gap and the political emphasis placed uponit on both sides of the Atlantic, very little systematic comparativeanalysis has been carried out on its causes. The empirical literaturehas emphasized the structural differences between the two continentsin the quantity and quality of the major ‘inputs’to innovation: R&D investments and human capital. The verydifferent spatial organization of innovative activities in theEU and the US—as suggested by a variety of contributionsin the field of economic geography—could also influenceinnovative output. This article analyses and compares a wideset of territorial processes that influence innovation in Europeand the United States. The higher mobility of capital, populationand knowledge in the US not only promotes the agglomerationof research activity in specific areas of the country but alsoenables a variety of territorial mechanisms to fully exploitlocal innovative activities and (informational) synergies. Inthe European Union, in contrast, imperfect market integrationand institutional and cultural barriers across the continentprevent innovative agents from maximizing the benefits fromexternal economies and localized interactions, but compensatoryforms of geographical process may be emerging in concert withfurther European integration.     

基于GWR模型的长江中游城市群传统村落空间格局及可达性探究

以长江中游城市群170个传统村落为研究对象,利用核密度法探讨城市群传统村落的空间分布特征,使用谷歌地图全球搜索引擎与相关公式测算各传统村落的可达性。运用地理空间计量方法GWR回归模型重点剖析影响城市群传统村落可达性水平重要因子的具体影响程度并考量其空间异化效应。研究表明：①长江中游城市群传统村落存在三个高度集聚区,呈"品"形分布,其中有两大集聚区处于环鄱阳湖城市群内部。②传统村落可达性整体水平不高,时间成本较大,所在地区路网密度低,交通便利性不高,并受明显的支流效应影响,水系、山体和交通将一定程度上影响村落的可进入性水平。③地势高低与路网等级对传统村落可达性水平具有正向作用,邻水体距离对传统村落可达性水平呈负相关关系,而坡度值对可达性影响不显著。     

城市群创新投入的空间格局与创新绩效研究——以长江经济带所辖城市群为例

创新投入在城市群内的空间格局是城市群内城市间创新功能分工的综合体现,对城市群整体创新绩效有着较为深刻的影响。基于此,本文以长江经济带6 大城市群为样本,借用城市基尼系数和城市首位度方法,计算了其创新投入的空间格局和演化趋势,并运用面板协整的方法分析了城市群整体创新绩效与创新投入空间格局之间的均衡及因果关系。研究发现：①6 大城市群中长三角城市群、武汉城市群和长株潭城市群的创新资源配置属于单核结构模式,其余的城市群为"双中心"或"多中心"模式;②城市群整体技术创新绩效与创新投入空间格局的城市首位度之间存在"倒U型"关系;③城市群技术创新绩效与城市首位度之间互为长期因果关系,但是从短期看,仅存在城市首位度对技术创新绩效的单向因果关系。     

从中外城市群发展看中原经济隆起——中原城市群发展研究

文章通过对区域城市化发展历程分析和世界城市化发展实践研究,指出了工业化、城市化是现代化的必然过程和结果,城市群是城市化发展的高级形式。我国正经历着城市化加速发展阶段,城市群是未来我国空间经济组织的主导形式。中原城市群将在我国产业布局和中原隆起中发挥重要作用。文章对中原城市群发展的优势、问题、空间组织、产业一体化、大郑州都市圈的发展进行了探讨,对快速运输系统、跨黄河发展、政府角色等问题进行了研究。     

Agglomeration and the Local State: The Tobacco Economy of Yunnan, China

This paper explores the interplay of local state action with historical contingency, innovation and external economies in the world's largest tobacco-producing region – Yunnan, China. Formed in a relatively unindustrialized province and promoted by local authorities as their primary revenue base, Yunnan's tobacco economy gained a headstart through concentrated resource support and ad hoc regulatory flexibility. Its further growth has drawn greatly on intraregional spillovers of knowledge of locally based institutional innovation, which foster and enhance conventional forms of external economies. Implications for the study of regional economies are discussed.     

关中、中原、山东半岛三城市群产业结构与分工的比较研究

采用区位商、相对专业化指数和相对多样化指数等指标定量分析了关中、中原、山东半岛三城市群的产业结构、专门化和多样化,并考察了它们与城市群发展之间的关系。通过指标计算与回归分析发现,目前三城市群总体上,相对全国而言的偏高的产业专门化和偏低的多样化,不利于城市群的发育;沿海和内地城市群的产业在发展动力方面存在着差异,沿海对产业多样化较敏感,而内陆则不显著;产业专门化不利于城市群发展,而多样化对城市群发展有一定的正向作用,但短期内作用并不明显。     

河南高新技术产业集聚分析

本文的研究表明,河南高新技术产业表现出十分明显的集聚特征,并依据其技术的先进性分化出3个空间层次。同时,在集聚主导下,河南高新技术产业布局还存在着分散化趋势。这种格局主要受区位效应、先行效应、企业扩张与衍生的本地化、地方政府的学习机制和发展产业的路径依赖等4个机制的共同作用。河南高新技术产业的集聚产生了明显的集聚效益,集聚效益与各高新区的集聚程度成正比。在此基础上,本文提出了优化高新技术产业布局,加快河南高新技术产业发展的建议。     

城市群作为国家战略:效率与公平的双赢

改革开放以来我国的区域战略和城镇化战略是根据不同的目的和需要而提出的,二者之间并没有建立内在有机的联系。以"科学发展观"和"五个统筹"思想为指导,以效率与公平的双赢为原则,提出了以大城市群为依托,将这两大战略有机结合起来作为国家战略的意义与构想。     

基于中部地区崛起的城市群整合发展

为协调区域发展,实现经济持续增长,国家作出了"中部地区崛起"这一重大决策。中部6省分别拥有中原城市群、武汉城市圈、长株潭城市群、环鄱阳湖城市群、皖江城市带和太原城市圈等6个城市群,城市群的整合发展在推动中部崛起进程中发挥着越来越突出的主导作用。在对中部地区城市群的现实基础与综合实力进行分析、评价的基础上,提出了基于中部崛起的城市群整合发展的总体意向和要解决的关键问题。整合发展的总体框架为:以武汉城市圈为核心增长板块,中原城市群和长株潭城市群为北、南牵引增长版块,沿交通大动脉京广铁路和长江黄金水道构筑两条南北、东西向城市群发展核心轴带,6个城市群并力互推,形成纵贯中部地区的"倒Y"字形发展格局。
