of the Exploratory Spatial Data Analysis (ESDA). It turned out that the average of SandT resource allocation efficiency in cities at prefecture level and above has always stayed at low levels, moreover, with repeated fluctuations between high and low, which shows
This paper has analyzed and discussed the spatial distribution pattern and evolution trend of science and technology (SandT) resource allocation efficiency in more that 286 cities, at prefecture level and above during 2001-2010, by virtue
a decreasing trend year by year. Besides, the gap between the East and the West is widening. Viewed from LISA agglomeration map of SandT resource allocation efficiency in different periods, four agglomeration types have changed differently in spatial location
and the range of spatial agglomeration. And the continuity of SandT resource allocation efficiency in geographical space is gradually increasing.

Based on provincial panel data of water footprint and grey water footprint, and with the help of data envelopment analysis model considering and without considering the undesirable output, this paper estimates the water resources utilization
efficiency in China from 1997 to 2011. The spatial weighting matrix based on economy-spatial distance function is established to discuss spatial autocorrelation of water resources utilization efficiency. With the help of absolute β-convergence model
, this paper concludes that there exists β-convergence in the water resources utilization efficiency. By mean of the spatial Durbin econometric model, this paper studies spatial spillover effects of the provincial water resources utilization efficiency in China

Meteorology Administration. Then they derived the spatial data set of 10 km monthly diffuse PAR using ANUSPLIN software, and analyzed the spatiotemporal variation characteristics of diffuse PAR through GIS and trend analysis techniques. The results showed
that : 1) The spatial patterns of annual average diffuse PAR during 1981–2010 are heterogeneous across China, lower in the northeast and higher in the west and south; 2) There is an evident increasing trend of annual diffuse PAR during recent 30 years
, but a significant declining trend is shown in the first 10 years, and obvious anomalies can be seen in 1982, 1983, 1991 and 1992; 3) The spatial distribution of temporal variation rates of diffuse PAR is inhomogeneous across the country, generally decreasing
On étudie les effets des retombées spatiales des crimes commis à l'intérieur de certains quartiers et la non-stationnarité en ce qui concerne les relations entre les facteurs contextuels et les crimes de voisinage. Une approche spatiale par SIG est

This study employs a spatial clustering method that exhaustively compares all U.S. counties on their age migration similarity and spatial proximity to investigate signature age-specific net migration profiles across six decades of U.S. county age
-specific net migration data from 1950 to 2010.As counties are merged by increasing large population thresholds, the Getis-Ord Gi spatial auto-correlation statistic is applied to examine how the spatial migration patterns are affected. It is found that U.S
. county age-specific net migration profiles exhibit four signature patterns. Although these patterns are persistent across the past six decades, their spatial distributions have experienced dramatic variation. The small population problem in net migration
rates affects the extent and loca-tion of the significant spatial migration patterns.

This article presents a new dasymetric methodology—the penalized maximum entropy dasymetric model that enables sources of uncertainty to be represented and modeled. It allows a rich array of data to be included, with disparate spatial resolutions
, attribute resolutions, and uncertainties. It also allows a rich array of data to be included, with disparate spatial resolutions, attribute resolutions, and uncertainties. It concludes by presenting an application that that includes household-level survey
data combined with higher spatial resolution data such as from census tracts, block groups, and land cover classifications in Davidson County, Tennessee.
archive is used to investigate transformations in the Atlantic coast of two Scottish islands over the period 1989–2011. Supervised classification of spectrally normalized images followed by change detection and spatialanalysis reveals the patterns
of change and the location of the most dynamic coastal areas. Quantitative measures of recent shifts and movement rates of relevant coastal lines, such as the lower limit of land-based vegetation, are assessed with the Digital Shoreline Analysis System
The purpose of this article is to provide an overview and evaluation of spatial clustering techniques, identifying the strengths and weaknesses of the most widely applied approaches. Results suggest that performance varies significantly in terms

Parce que les données spatio-temporelles sur la criminalité ont des composants temporels aussi bien que des composants spatiaux, les modèles poissonniens doivent être de nouveau ajustés pour refléter les deux types de composants simultanément

This article uses local indicators of spatial association (LISA) and other spatialanalysis techniques to analyze the distribution of centers with high employment density within metropolitan areas. It examines the 359 metropolitan areas across
the United States at three points in time (1990, 2000, and 2010) to provide a spatio-temporal panoramic of urban spatial structure. Our analysis highlights three key findings. (1) The monocentric structure persists in a majority of metropolitan areas: 56.5

On analyse l'effet des innovations technologiques sur la croissance économique régionale du Mexique dans les années 1995-2007. L'inclusion d'une dimension spatiale dans l'analyse empirique est encore peu pratiquée, ainsi que le modèle d'interaction
spatiale et les effets possibles de la diffusion spatiale. On applique les méthodes de l'analyse de données spatiales. L'innovation technologique a un effet positif sur la croissance économique régionale du Mexique. Il y a un effet positif venant des effets
de diffusion transfrontaliers des connaissances technologiques. Les Etats dans lesquels les activités innovantes sont plus influentes ont profité d'externalités technologiques spatiales et d'une croissance économique plus rapide.
