金融集聚研究进展与展望

金融业集聚属于服务业集聚范畴,既与制造业集聚有共性,又有其独特性。金融集聚的研究主要依托于区位理论、集群理论和金融地理学。区位理论是金融集聚的理论基础,集群理论为金融集聚提供了研究范式,金融地理学的发展为金融集聚研究带来新的动向。金融集聚的现有研究内容主要集中于对集聚的动因、类型、效应、模式的探讨,以及金融中心的构建等几个方面。随着全球化、信息化对金融业的发展布局影响越来越大,未来应重点加强对金融分支行业和微观区域方面的研究。     

Spatial Organization of Fortune Global 500 Corporations in China: An Empirical Study of Multinationals from Japan,the United States,and European Union

Using data on investments in China from Fortune Global 500 multinational corporations (MNCs) based in Japan, the United States, and European Union over a three-decade period, the authors document the gradual expansion of MNCs in China both functionally and geographically. Statistical analysis suggests the existence of significant intra-firm clustering as a result of sequential investments, as well as country-of-origin agglomeration in the case of MNCs from Japan. Disaggregated analysis, however, reveals that functional and cross-functional mutual avoidance (e.g., intra- and inter-firm competition) in the location of MNC subsidiary firms tends to mitigate country-of-origin agglomeration effects.

Geographical Concentration of Manufacturing Industries in China: The Importance of Spatial and Industrial Scales

Using the most recent data from the first economic census in China, a team of China-based and American economic geographers investigates the geographical concentration of manufacturing industries at the provincial and county levels by integrating proxy variables for natural advantages, agglomeration economies, and institutional changes (e.g., decentralization) associated with economic transition. The authors focus their investigation on manufacturing activity as a whole, as well as on manufacturing categories at the two- and three-digit levels of aggregation (the latter representing a finer scale of analysis than used in almost all previous studies). Interesting differences emerge in the locational patterns of industries whose enterprises pursue strategies of globalization vis-à-vis local protectionism. Differences also are apparent in the impacts of agglomeration economies and knowledge spillover at different spatial scales. The findings suggest that both spatial scale and level of industrial aggregation matter when analyzing patterns of industrial agglomeration in China.

An analytically solvable core-periphery model

We develop an analytically solvable version of the central modelof ‘new economic geography’, the so called core-peripherymodel by Krugman. While the modified model reproduces all theappealing features of the original one, it also allows us toobtain additional analytical results that are out of reach inKrugman's set-up. First, we are able to assess the exact numberof equilibria and their global stability properties. Second,we are able to investigate the implications of exogenous asymmetriesbetween countries. This is achieved by introducing heterogeneitybetween high-skill mobile and low-skill immobile workers, whichmay also be an empirically attractive property.     

高速铁路对湖南城市群可达性的影响

引入可达性的概念,以现阶段与预期2030年的湖南城市群综合铁路网数据为基础,选取加权平均旅行时间、经济潜力和日常可达性3个度量指标,比较分析了高速铁路的发展对湖南城市群城际间8城市可达性的影响。结果表明:高速铁路大大缩短了城际之间的时空距离,将全面提升湖南区域可达性水平,促进区域均衡化空间结构的形成;另一方面,尽管高速铁路将推动多中心空间结构的形成,但对湖南城市可达性水平的影响具有明显的区域差异,可分为两个层级,各城市在新的交通格局下应抓住机遇,探寻符合自身特点的发展道路。     

美国大都市区尺度上的工业区位研究

工业化和城市化之间的互动关系体现在都市区尺度上的工业区位上。本文在新经济地理学和城市地理学所揭示的产品差异化和城市集聚效应相互关系的基础上,通过区位熵分析、赫芬达尔-赫希曼指数,对美国工业区位与大都市区间的耦合关系进行实证研究。结果显示:集聚于大都市区核心区的往往是产品个性化和定制化程度较高的行业;位于大都市区外围区的大都是产品依赖于城市市场,但标准化程度较高的行业;传统制造业则往往位于非大都市区。多数都市工业的市场集中度较低,而大部分传统工业的市场集中度较高。这不仅印证了新经济地理学的理论推演和城市地理学的行业分析,而且对包括中国在内的转型国家城市及其产业发展具有重要的参考意义。     

The effect of congestion and agglomeration on multifactor productivity growth in Dutch regions

It is well known that labour productivity growth in Europe isslowing down, against an increasing growth rate in the US. TheNetherlands is one of the countries in Europe with the lowestgrowth rates of productivity. This article looks at this phenomenonfrom a regional perspective and presents the results of a growthaccounting exercise applied to regional industry data of TheNetherlands between 1995 and 2002. We find that slow productivitygrowth in The Netherlands is particularly situated in the economiccore regions and is caused by slow multifactor productivity(mfp) growth. A substantial part of this slow mfp-growth canbe explained by the fact that positive agglomeration advantagesare overruled by negative congestion effects caused by trafficjams.     

百年来国际组织机构地理位置的时空演化:集聚模式与影响因素

国际组织机构在构建国家软实力、拓展国家利益、塑造全球治理机制具有不可替代的战略意义。论文基于国际协会联盟数据,运用矢量数据符号法和负二项回归模型对1918年至2017年成立的26457个国际组织机构地理位置的时空演化规律进行深入研究,主要结论如下：①百年来国际组织机构累计数量呈几何数量级增长了1200倍,整体呈缓慢上升又陡然下降的演化趋势;②国际组织机构的空间分布极不均衡,具有等级扩散的演化规律,优先选择区域中心国家的中心城市;③国际组织机构具有永久中立国、强国和区域中心国三种集聚模式;④回归显示国家的经济、文化和科技影响力及历史性组织文化遗产在0.01水平上与国际组织机构地理布局呈显著的正相关关系。     

新国家空间理论视角下城市群的国家空间选择性研究

基于新国家空间理论,将城市群置于社会经济转型宏观背景下,分析其空间选择的国家空间项目与国家空间策略,并初步探讨了其空间效应。城市群作为目前国家空间选择性的具体形式,其产生背景、依据以及生产策略体现了国家空间选择性内涵与演变路径,是国家应对城市企业主义危机采取的一种新型城市与区域治理形式。在国家空间项目及其策略的支持下,城市群享有优先于其它地区发展的特权并实现经济快速发展,从而培育地方增长极并推动区域协调发展。然而,城市群的空间选择并未改变城市企业主义的逻辑而是将其转移到了区域尺度,并且存在城市间竞争激烈等一系列问题,亟待与其它空间项目与策略的配套实施以实现区域崛起并提高国家竞争力。     

Determinants of postdisplacement reemployment outcomes and occupation changes

We investigate the roles played by agglomeration (proxied by population density) and occupational distribution on postdisplacement employment outcomes for US workers, focusing on the probability of being employed, the likelihood of changing occupations, and the occupational distance between the old and new occupations (where occupational distance is defined as the difference in job tasks between two occupations). Overall, we find that the local occupational distribution has a greater impact on our outcome variables compared with our agglomeration measure. Our findings suggest policy makers should look closely at occupational distribution when designing job training programs and proposals for relocation vouchers.
