乡村振兴背景下农村基本公共服务与多维贫困的时空耦合特征研究

村级尺度上探索农村基本公共服务与区域贫困之间的关联特征以及二者耦合作用机理,是实现精准扶贫与乡村振兴战略有机结合的重要一环。本文分别建立农村基本公共服务和多维贫困综合发展监测模型,结合时空探索性分析和耦合协调分析方法,综合揭示两者的时空发展分布特征及其耦合关联关系。2015—2018年研究区内58个行政村的实证结果表明：①研究区内农村基本公共服务的发展呈中段高、南北段低的空间非均衡性分布,整体发展差异呈缩小趋势;②研究区内贫困村的多维贫困状况在空间分布上呈现出中北段地区贫困程度较轻、南段贫困程度较深的格局;③农村基本公共服务与多维贫困存在空间负相关性关联与明显耦合,且自实施乡村振兴战略以来,贫困村多转为同步型发展。研究结果可为现阶段乡村振兴战略的实施提供科学的决策依据和参考。     

季节时空交互视角下老年人公交移动性的影响因素研究——以芜湖市为例

公共交通是我国老年人出行的主要交通方式之一,公交移动性是衡量老年人生活质量和幸福感的重要指标。从季节和空间双重维度分析老年人公交移动性的影响因素有助于深入理解老年人出行行为机制。利用公交刷卡数据和地理探测器方法分析了季节时空因子对老年人公交移动性的影响。研究发现：①不同季节中空间因子对老年人移动频率、移动半径和移动熵的解释力和显著性存在明显差异,对老年人移动性影响机制的分析应考虑时空变化的双重影响;②不同空间因子之间以及季节与空间因子之间的交互作用可以显著增强对老年人移动性空间分异的解释力,考虑多个因素的协同效应对深入理解老年人行为有一定帮助。研究试图拓宽老年人移动性影响因素的分析思路,为老年宜居城市建设和城市移动性规划提供重要支撑。     

移动地理研究的一种理论框架——基于文献分析

移动性是21世纪人文地理的研究热点和重要议题,它体现了空间科学的社会学转向,属于人文地理学的核心概念和中心命题,其中心性突出体现在它与其他传统和新兴的人文地理分支学科的交叉。本文以表格为工具梳理了地理移动性的研究理路,发现移动地理与其他人文地理分支学科共同聚焦的核心是：时间地理、旅游地理、行为地理的“时空行为”问题,政治地理、社会地理的“权力”“平等”“权利”问题,身体地理的“具身实践”“感官体验”问题,情感地理的“地方依恋”“身份认同”问题,想象地理的“地方感”问题,道德地理的“空间道德感”问题。本文识别这些关键问题为移动地理的“核心要素”,搭建移动地理的框架和体系,指出探查这些要素之间相互作用机制和不同时空移动类型的转化机理是未来移动性的研究方向。根据移动的空间尺度和时间强度,构建了包括日常移动、旅游和旅行移动到永久性移动在内的地理学移动性连续轴类型,并探索了移动地理研究的方法论体系。     

Exploring the associations between cooling centre accessibility and marginalization in Montreal,Toronto, and Vancouver,Canada

Cooling centres provide respite, safety, and social support during extreme heat events for populations that do not have the resources to own or operate in-home air conditioning. The objective of this study was to measure the spatial accessibility of cooling centres and analyze the associations between cooling centre access and marginalization in Montreal, Toronto, and Vancouver, Canada. The potential spatial accessibility of cooling centres within a 15-minute walk was measured at the dissemination area scale using the two-step floating catchment area method. A two-stage modelling approach was used to analyze the associations between cooling centre access and marginalization. Approximately 62%, 58%, and 54% of the populations in Montreal, Toronto, and Vancouver had access to at least one cooling centre. In Montreal and Vancouver, high marginalization areas were more likely to have cooling centre access than low marginalization areas. Of the areas with cooling centre access, smaller access scores were observed in areas with high residential instability. Approximately one-fifth of the areas in each city had no cooling centre access and high marginalization, and may be considered for future cooling centres or programs that improve accessibility to existing centres.     

The ripple effects of large-scale transport infrastructure investment

We analyze the general equilibrium effects of an asymmetric decrease in transport costs, combining a large-scale spatial dynamic general equilibrium model for 267 European NUTS-2 regions with a detailed transport model at the level of individual road segments. As a case study, we consider the impact of the road infrastructure investments in Central and Eastern Europe of the European Cohesion Policy. Our analysis suggests that the decrease in transportation costs benefits the targeted regions via substantial increases in gross domestic product (GDP) and welfare compared to the baseline, and a small increase in population. The geographic information embedded in the transport model leads to relatively large predicted benefits in peripheral countries such as Greece and Finland, which hardly receive funds, but whose trade links cross Central and Eastern Europe, generating profit from the investments there. The richer, Western European nontargeted regions also enjoy a higher GDP after the investment in the East, but these effects are smaller. Thus, the policy reduces interregional disparities. There are rippled patterns in the predicted policy spillovers. In nontargeted countries, regions trading more intensely with regions where the investment is taking place on average benefit more compared to other regions within the same country, but also compared to neighboring regions across an international border. We uncover that regions importing goods from Central and Eastern Europe enjoy the largest spillovers. These regions become more competitive and expand exports, to the detriment of other regions in the same country.     

Evidence on economies of scale in local public service provision: A meta-analysis

The standard theory of optimal jurisdictional size hinges on the existence of economies of scale in the provision of local public goods and services. However, despite its relevance for forced local amalgamation programs and related policies, the empirical evidence on the existence of such economies of scale remains elusive. The main goal of this paper is to produce an updated and comprehensive quantitative review of the existence of economies of scale in the provision of local public goods using a meta-analysis approach to systematize the wide range of empirical approaches and modeling frameworks found in the previous literature. Our analysis confirms the presence of moderately increasing to constant returns to scale in the provision of local services with no reduction in the average costs of production in the delivery of most local public services beyond a certain, modest jurisdictional size, which many studies have estimated at 10,000 residents. Also, the potential for economies of scale differs at least across three traditional services: education, water and sanitation, and garbage collection, being highest for education and lowest for garbage collection. Our analysis also offers guidelines for future empirical research in this area. Physical output and production cost data should be used, together with translog specifications for the modeling of cost functions. Last, we find evidence that the determinants of output cost elasticity include bidirectional publication bias and population density but do not include the presence or absence of modern “lean” production technologies or the (perceived) capital intensity of the sector, contrary to conventional wisdom. These findings have significant policy implications for countries considering jurisdictional consolidation programs.     

Cultivation History Beyond the Periphery: Early Agriculture in the North European Boreal Forest

We have investigated the environmental history of human occupation and the development of agriculture in the eastern interior Lake District of Finland. The material consists of archaeological data, which is reviewed in topographical and agrogeological context, and pollen analytical evidence of agricultural indices from eight precisely dated (varved) lake sediment sequences. Before the Viking Age, archaeological evidence, consisting of stray finds, dwelling sites, and graves, is very scarce. Iron Age finds are clearly confined to the lowland environs with silty and clayey soils. During the Viking Age, the number of stray finds multiplies and the first cemeteries are established. Comparison between Viking and Crusade Period finds reveals a topographic shift toward higher locations and morainic soils. Most of the cup-stones are located on upland sites—that is, not in connection with known Iron Age sites. These are interpreted as medieval indicators of slash-and-burn farming of the fertile but stony supraaquatic morainic soils. There is pollen analytical evidence of sporadic cultivation in the area from the Bronze Age onward. Afterca. AD 700, the occurrence of cereal pollen grains becomes regular but remains discontinuous at each site until after the turn of the millennium. There is then an exponential rise in the cereal pollen rain, indicating a fully agricultural population.     

Ancestral pueblo population aggregation and abandonment in the North American Southwest

After over a century of archaeological research in the American Southwest, questions focusing on population aggregation and abandonment continue to preoccupy much of Pueblo archaeology. This article presents a historical overview of the present range of explanatory approaches to these two processes, with a primary focus on population aggregation in those regions occupied by historic and prehistoric Pueblo peoples. We stress the necessarily complementary nature of most of these explanations of residential abandonment and aggregation. Case studies from the northern Southwest illustrate the continuous nature of these processes across time and space. We suggest that additional explanatory potential will be gained by the use of well-defined theoretical units to frame our current approaches. We extend the use of the local community concept as a theoretical unit of organization that, along with explicit archaeological correlates, should help advance our research into population aggregation and abandonment in this and other regions of the world.
