This article explores the role of evolutionary economic geography in enhancing understanding and implementation of the circular economy (CE). By incorporating spatial and territorial dimensions into CE research, this study emphasizes the significant influence of geographical factors on achieving economic and environmental objectives. The research highlights the importance of localizing CE practices and emphasizes the contributions of proximity theory and territorial governance in promoting collaborative networks that are crucial for CE success. Furthermore, the article introduces the concept of Territorial Circular Ecosystems, which provides a framework for analyzing regional variations and the interplay between local actors, resources, and institutional support in the deployment of the CE. The findings offer fresh insights for policymakers and researchers, advocating for place-based policies to address CE challenges and optimize sustainability strategies.

Digital business-to-business (B2B) platforms have become essential components of today's economy. However, the impact of digital B2B platforms on global production networks has not yet been sufficiently conceptualized and empirically examined. This article proposes an analytical framework to theorize platform-based reconfigurations of global production networks. By using the case of digital logistics platforms, the article illustrates that service-centred platforms, in particular, have a major impact on global production networks, as they are able to position themselves as lead firms and to utilize data to shape the organizational and spatial composition of global production networks.
企业对企业(B2B)数字平台已成为当今经济的重要组成部分。然而,数字 B2B 平台对全球生产网络的影响尚未得到充分的概念化和实证研究。本文提出了一个分析框架,对基于平台的全球生产网络重构进行理论分析。文章以数字物流平台为例,说明以服务为中心的平台尤其对全球生产网络具有重大影响,因为它们能够将自己定位为主导企业,并利用数据来塑造全球生产网络的组织和空间构成。

Economic geography data are typically reported using political units, such as counties, which often do not match economic units. Commuting zones (CZs) group counties into labor markets. However, CZs are not the most appropriate grouping for other economic activities. We introduce consumption zones (ConZs), groupings of counties appropriate for the analysis of consumption. We apply CZ methodology to payment card data, which report spending flows across US counties for fifteen industries. We find that different industries have different market sizes. Grocery stores have more than five times the number of ConZs as entertainment. We apply ConZs to measuring industry concentration.
经济地理数据通常使用县等政治单位进行报告,而这些单位往往与经济单位不匹配。通勤区(CZ)将各县划分为劳动力市场。然而,对于其他经济活动而言,通勤区并不是最合适的分组方式。我们引入了消费区(ConZs),即适合消费分析的县域分组。我们将 CZ 方法应用于支付卡数据,该数据报告了美国 15 个行业的跨县消费流。我们发现,不同行业有不同的市场规模。杂货店的 ConZ 数量是娱乐业的五倍多。我们将 ConZs 用于衡量行业集中度。

On 5 June 2017, an airspace blockade was imposed on the State of Qatar by Bahrain, Saudi Arabia, United Arab Emirates (neighboring countries), and Egypt. We exploit this exogenous increase in air transportation costs toward non-blockading countries to examine the effect of increased travel distance, due to re-routing, on bilateral trade. Based on a gravity model estimated using a Poisson pseudo-maximum likelihood estimator, we find a distance elasticity of imports between −0.3 and −0.5. Overcoming the limitations of cross-sectional studies and taking advantage of this quasi-natural experiment, our findings are robust and revise downward previous estimates of the distance elasticity.
2017 年 6 月 5 日,巴林、沙特阿拉伯、阿拉伯联合酋长国(邻国)和埃及对卡塔尔国实施了空域封锁。我们利用飞往非封锁国的空运成本增加这一外生因素,考察了因改道而增加的旅行距离对双边贸易的影响。基于使用泊松伪极大似然估计法估算的引力模型,我们发现进口的距离弹性在-0.3 和-0.5 之间。我们克服了横截面研究的局限性,利用这一准自然实验,得出了稳健的结论,并向下修正了之前对距离弹性的估计。

We revisit the natural experiments of division and unification of Germany. The negative shock to local market access following the division of Germany led to a fast and strong downward adjustment of the size of West German cities near the new border. In contrast, the positive shock of reunification did not lead to any change in their relative size. Even three decades after reunification, no convergence can be observed. We show that local subsidies to East Germany could have contributed to this asymmetry in time.
我们重温了德国分裂和统一的自然实验。德国分裂后,对当地市场准入的负面冲击导致新边界附近的西德城市规模迅速而强烈地下调。与此相反,统一带来的积极冲击并没有导致这些城市的相对规模发生任何变化。即使在德国统一三十年后,也没有发现任何趋同现象。我们的研究表明,对东德的地方补贴可能导致了这种时间上的不对称。

In recent decades, renewable energy cooperatives have substantially increased their share of renewable energy production. The operation of these cooperatives requires collective action, potentially supported by local social capital. We investigate whether municipal-level bonding and bridging social capital explain the differences in the prevalence of renewable energy cooperatives across Dutch municipalities. We measure social capital directly from social network structures within and between municipalities, thus overcoming limitations of using proxies. Our empirical results reveal that bonding rather than bridging social capital supports renewable energy cooperatives, shedding new light on the role these types of social capital play in regional development.
近几十年来,可再生能源合作社大大增加了其在可再生能源生产中的份额。这些合作社的运作需要集体行动,并可能得到当地社会资本的支持。我们研究了市级纽带和桥梁社会资本是否可以解释荷兰各市可再生能源合作社普及率的差异。我们直接从市镇内部和市镇之间的社会网络结构来衡量社会资本,从而克服了使用代用指标的局限性。我们的实证结果表明,支持可再生能源合作社的是纽带型社会资本而非桥梁型社会资本,这为我们揭示这些类型的社会资本在区域发展中的作用提供了新的思路。

In urban economics, transportation costs are a key determinant of land value. However, in virtual worlds, these costs are generally limited by the users’ ability to teleport. Drawing from urban and attention economic literature, we propose a theoretical model microfounded on user behavior. The model suggests that the relative value of land parcels hinges on their potential to attract visitors. Our empirical analysis supports this by demonstrating that location remains crucial in virtual worlds and highlighting the role of the teleportation threshold. We discuss the model’s general applicability, reaffirming the significance of location within most virtual worlds.
在城市经济学中,交通成本是决定土地价值的关键因素。然而,在虚拟世界中,这些成本通常受到用户远程传送能力的限制。借鉴城市和注意力经济学文献,我们提出了一个以用户行为为微观基础的理论模型。该模型表明,地块的相对价值取决于其吸引游客的潜力。我们的实证分析证明了这一点,即在虚拟世界中,位置仍然至关重要,并强调了远程传送门槛的作用。我们讨论了该模型的普遍适用性,重申了位置在大多数虚拟世界中的重要性。

This article studies the effect of return initiatives in rural regions of Germany on interregional return migration. The initiatives aim to increase return migration by, amongst other things, providing information on local employment opportunities and personal support to workers interested in returning to find a job in the former rural region of residence. Analysing administrative data on individual labour market trajectories through survival analysis and difference-in-differences estimation, we find that return initiatives, on average, promote interregional return migration. Among the considered workers, particularly those in the middle and at the top of the wage distribution are more likely to return.
本文研究了德国农村地区的回流计划对地区间回流移民的影响。这些措施旨在通过提供当地就业机会信息和个人支持,帮助有意回流的工人在原居住地找到工作,从而增加回流移民人数。通过生存分析和差分估算对个人劳动力市场轨迹的行政数据进行分析,我们发现,平均而言,回流计划促进了地区间的回流。在所考虑的工人中,尤其是处于工资分布中间和顶端的工人更有可能回流。

We study whether highway and railroad improvements cause population suburbanization in Europe’s cities. We construct a unique population and transportation dataset covering 579 cities from 29 European countries for the period 1961–2011. In order to make a causal inference, we rely on historical instruments. Our average results indicate that highways, but not railroads, were responsible for the suburbanization process: each additional highway ray decreased the share of the central city population by 5 percentage points, whereas new railroads had no impact. The heterogeneity analyses provide evidence of different patterns based on the time of the investment, the city’s size and density, and its geographical location.
我们研究了高速公路和铁路的改善是否会导致欧洲城市人口郊区化。我们构建了一个独特的人口和交通数据集,涵盖了欧洲 29 个国家的 579 座城市,时间跨度为 1961-2011 年。为了进行因果推断,我们使用了历史工具。我们的平均结果表明,高速公路而非铁路对郊区化进程负有责任:每增加一条高速公路射线,中心城市的人口比例就会减少 5 个百分点,而新建铁路则没有任何影响。异质性分析提供了根据投资时间、城市规模和密度以及地理位置而形成不同模式的证据。

We develop monthly asylum seeker flow forecasting models for 157 origin countries to the EU27, using machine learning and high-dimensional data, including digital trace data from Google Trends. Comparing different models and forecasting horizons and validating out-of-sample, we find that an ensemble forecast combining Random Forest and Extreme Gradient Boosting algorithms outperforms the random walk over horizons between 3 and 12 months. For large corridors, this holds in a parsimonious model exclusively based on Google Trends variables, which has the advantage of near real-time availability. We provide practical recommendations how our approach can enable ahead-of-period asylum seeker flow forecasting applications.
我们利用机器学习和高维数据(包括来自谷歌趋势的数字跟踪数据),为 157 个原籍国开发了欧盟 27 国寻求庇护者月度流量预测模型。通过比较不同的模型和预测期限并进行样本外验证,我们发现,在 3 到 12 个月的期限内,结合随机森林和极端梯度提升算法的集合预测优于随机漫步预测。对于大型走廊,这一点在完全基于谷歌趋势变量的简约模型中是成立的,该模型具有接近实时可用性的优势。我们将就如何利用我们的方法提前预测寻求庇护者的流量应用提供实用建议。
