Convergence and Spillover Effects in Africa: A spatial Panel data Approach

JOURNAL OF AFRICAN ECONOMIES 2018年第3期27卷 274-284页

作者： Diop, Samba Gaston Berger Univ St Louis Fac Econ & Management BP 234 St Louis Senegal

This paper re-examines the question of beta convergence process among 45 African countries during the period 2000-2015, taking into account the existence of spatial dependence and spatial spillover effects. We use a spatial panel data approach to control both individual effects and interaction among geographical units. The exploratory spatial data analysis detects strong spatial dependence and clusters of high per capita income in northern, central and southern Africa. Our empirical results find the existence of beta convergence and suggest that dependence between economies has an adverse impact in the convergence speed for African countries. We also find the existence of spatial spillover effects. This result suggests that in Africa, having neighbours with higher levels of initial per capita income leads to higher growth rates.

Regional development programs in the regional autonomy policy require the smallest area unit information. One of those programs is the construction of health facilities. The process of health development in the future requires the pattern of distribution of health facilities that already exists today. Distribution of health facilities in the province of Yogyakarta is still concentrated in urban areas, and the number of health facilities is not comparable with the area of each district. Therefore spatial data analysis using exploratory spatial data analysis (ESDA) is needed in order to see the pattern of accessibility level of existing health facilities. spatial analysis considers the spatial correlation among the regions as the object of research. The existence of health facilities in a village will influence the accessibility to health facilities in another village. This paper uses health facilities index to find spatial clusters of accessibility level. New method based on administrative boundaries is added to this analysis as weights matrix to be compared with existing methods in GeoDa tools. The experiments show the use of weights matrix by administrative boundaries gives the best result. This weighing has the highest Moran's I, so it is more suitable weighing method for this analysis. Furthermore, the spatial clustering of the easiest access to health facilities occurs in the urban areas and some area around them, such as in Yogyakarta City and Sleman Regency near Yogyakarta City, also in central government area.

作者： Anselin, Luc Kim, Yong Wook Syabri, Ibnu Spatial Analysis Laboratory Dept. of Agric./Consumer Economics Univ. of Illinois Urbana-Champaign Urbana IL 61801 United States

This paper deals with the extension of internet-based geographic information systems with functionality for exploratory spatial data analysis (ESDA). The specific focus is on methods to identify and visualize outliers in maps for rates or proportions. Three sets of methods are included: extreme value maps, smoothed rate maps and the Moran scatterplot. The implementation is carried out by means of a collection of Java classes to extend the Geotools open source mapping software toolkit. The web based spatial analysis tools are illustrated with applications to the study of homicide rates and cancer rates in U.S. counties. © Springer-Verlag 2004.

Hit the Road: spatial Characteristics of Labor Absorption in South Africa

PROFESSIONAL GEOGRAPHER 2024年第3期76卷 331-342页

Unequal spatial concentration is at the heart of economic imbalance in South Africa. This research aimed at spatially characterizing labor absorption patterns and exploring the link to spatial development. Labor absorption is often used as an indicator of labor market well-being and for many countries, the indicator is often more insightful than the unemployment rate. The research used secondary data to create a longitudinal data set of labor absorption, functional literacy, the ratio of urban population and gross domestic product growth rate, among others, at a municipal level. exploratory spatial data analysis and thematic mapping were undertaken to illustrate the characteristics of the labor market, while spatial grouping created clusters of municipalities based on labor absorption. A positive upward trend was observed between labor absorption and the share of people in an urban area;that is, the more urban an area, the higher the labor absorption rate. Furthermore, the spatial clustering of municipalities highlighted linear patterns and when this was overlayed with roads and development corridors, clearly indicated the impact of regional spillovers. The findings suggest a more integrated focus on regional innovation policy to reduce spatial disparities in the economic landscape.

As globalization processes continue to impact patterns in drug-trafficking operations worldwide, a cyber-based dimension of the drug trade has recently emerged via the Tor Network. This study employed geovisualization and exploratory spatial data analysis to examine drug distributions of heroin, cocaine, new psychoactive substances, and prescription drugs advertised on Agora, the largest international marketplace on the Tor Network at the time of data collection. data were collected using webcrawling software and mapped to determine the presence of statistical outliers internationally or hotspots within Europe. Global Moran's I testing revealed that drugs sourced from Europe were randomly distributed. Boxmaps confirmed the visual analysis that six countries (including Canada and the United States) dominated world listings across the four drug types. Globally, heroin and cocaine markets were found to be almost exclusively retail based, while new psychoactive substances and prescription drugs were sold from countries with established pharmaceutical and chemical industries.

Urban tourism is booming and, as a result, crowding is now recognized as a social constraint in many tourist cities. When related to sustainability, tourism crowding must be considered. However, the way tourists experience crowding is still a neglected topic in urban tourism research. In this study, we proposed a new approach to exploit tourism crowding from crowdsourcing geospatial data which goes beyond the scale, timeliness, and cost of traditional on-site questionnaire surveys. The new approach is based on analysis of 446,273 check-in' geotagged data from Weibo in Shanghai. The data provided a hotspot distribution of popular urban tourist attractions and a range of factors related to tourism crowding. These data provided deep insights into the relationship between crowdedness and popularity of tourist attractions. This empirical work can be extended to urban tourism crowding management environments for sustainable development of tourist attractions.

A stop too far: How does public transportation concentration influence neighbourhood median household income?

Research on US cities has connected the concentration of public transit with various neighbourhood outcomes, but it remains unclear whether public transit was more attractive to lower or higher income households. Some research found neighbourhoods with public transportation were more attractive to lower income households, likely because such households could not afford private transportation. Closer examination suggested that the type of transit was important, as lower income households were more likely to use buses while higher income households were more likely to use rapid transit. A key limitation of existing research on transit and neighbourhood household income was that it did not adequately control for variation over time. The current study addresses this limitation by assessing how the concentration of subway and bus stops predicted variation in median household income in New York City during the 2000s. Results of cross - sectional regressions partially confirm the findings of previous research that lower income households corresponded to areas characterised by higher concentrations of bus stops. Longitudinal results, however, indicate that the concentration of different forms of transit was uniquely associated with changes in neighbourhood median household income, independent of other neighbourhood changes.

Cloud mapping platforms, such as Google Maps, CartoDB, MapZen, and the like have become powerful alternatives to traditional desktop-based mapping and GIS applications. However, unlike their desktop counterparts, web mapping platforms typically do not contain any but the most basic spatial analytical functionality. In this paper, we introduce GeoDa-Web, a cloud mapping platform that integrates spatial analytics and web mapping. The platform enables researchers to retrieve spatial data from the cloud, conduct spatial analysis in the cloud, visualize results using cloud mapping, and publish maps and plots to social media in a user-friendly way. It leverages the code base from the widely used GeoDa desktop software for spatial data exploration and the PySAL Python library of spatial analytical functions. We outline the architecture, discuss the implementation and illustrate the functionality of GeoDa-Web.

BROADBAND PROVISION AND FIRM LOCATION IN OHIO: AN exploratory spatial analysis

引用

TIJDSCHRIFT VOOR ECONOMISCHE EN SOCIALE GEOGRAFIE 2009年第3期100卷 298-315页

作者： Mack, Elizabeth A. Grubesic, Tony H. Indiana Univ Dept Geog Bloomington IN 47405 USA

Information and communication technologies (ICTs) are often cited as an important factor in firm location decisions. This is especially true for firms engaged in information intensive activities and those that have a strong need for advanced services such as broadband. Despite the suggested importance of these technologies, quantitative work evaluating the link between firm location and broadband provision is sparse and existing knowledge remains largely theoretical and speculative. However, theoretical evaluations of the impact of ICTs on firm location do provide a foundation for quantitative analyses of this relationship and may be grouped into three schools of thought: the deconcentration school, the concentration school, and the heterogeneous effects school. The predictions made by these three schools of thought will be analysed in an exploratory context to better understand the relationship between firm location and ICTs, with a focus on broadband service provision. A combination of basic spatial statistical analytical tools and geographic information systems (GIS) will be used in an exploratory spatial data analysis framework to evaluate the relationship between firm location and broadband provision trends from 1999 to 2004 in the state of Ohio. Results suggest that changes in broadband provision have no relationship with changes in firm location. However, a disaggregated, firm level analysis of this relationship does provide statistically significant results for a subset of industrial sectors. Firm size is also found to impact the correlation between firm presence and broadband provision. These results suggest that firm size and industry are perhaps critical components in determining the relative importance of ICTs, such as broadband, in firm location decisions.
