The Primary Factors for Spatial Differences in Local Religions影响地方神信仰差异的主要因素朱海滨:《祭祀政策与民间信仰变迁-近世浙江民間信仰研究》上海:复旦大学出版社,2008 • 自然灾害 • 产业形态 • 交通与地理 • 乡土意识 • 迁入移民 • 巫、道文化 • 宗教与环境 • 宗教与经济 • 宗教与与地理 • 宗教与文化 • 宗教与移民 • 宗教与宗教 • 。。。。 • 宗教与历史 • 宗教与政治 • 宗教与管理
Spatial Analysis of Religions • Identify the spatial patterns of religious, demographic and socioeconomic distribution. • Identify the spatial interactions (linkages) between religious and other aspects of the society. • Evaluate the impacts of religions on future development of the society.
Demand for Spatial Analysis • How can we use the data from different sources, time, and formats? • What is the spatial patterns of data distribution? • How the spatial patterns changes over the time? • How the observations are interacted over the time and space? • How different factors are interacted each other over the time and space ?

Spatial Data of China • 2000 China Township Population Census Data with GIS Maps • 2000 China County Population Census Data with GIS Maps (Version III) • 2000 China Province Population Census Data with GIS Maps • 2000 China Grid Population Census Data with Township Boundaries • China Historical Province Population Census Data with GIS Maps (1953, 1964, 1982, 1990, 2000) • China Historical County Population Census Data with GIS Maps (1953, 1964, 1982, 1990, 2000) • China 1995 Industrial Census Data with GIS Maps • China 2001 Basic Unit Census Data with GIS Maps • China 2004 Economic Census Data with GIS Maps • China City Statistical Indicators with Maps (1996-) • Geographic Layers (rivers, lakes, roads, highways, railways)
Spatial Statistics • Tests on spatial patterns: • Tests on spatial non-stationarity • Tests on spatial autocorrelation • Data-driven approaches (Exploratory Spatial Data Analysis) • Global Statistics • Local statistics • Model-driven approaches • Spatial linear and non-linear models • Space-temporal models
Difference between Conventional Statistics and Spatial Statistics Con. statistics Spatial statistics Data: Time-series data Spatial data (cross-sectional) Relationship: Time (yt-1, yt, yt+1) Topology (yi-1, yi, yi+1) Process: {Z(t), tT} {Z(s;t), sD(t), tT} Model: Y = WY + t = 1, 2, 3, … wi,j= 1 if i is adjacent to j - time-series - spatial autocorrelation autocorrelation
Defining Spatial Linkage (Weights) • Criteria: theoretical and empirical • Accessibility (roads, rivers, railways, airlines and Internet) • Economic linkage (commuter flows, migrations, trade flows) • Social linkage (college admission, language) • Locational linkage (neighborhood, geographical distance) • Methodology: • Binary matrix • Row standardized matrix • Weight function (wij=f(x,y..))
Identifying Spatial Trend Theoretical Variogram: Experimental Variogram: where N(hk)={(i,j): xi-xi_=h}, |N(hk)|is the number of distinct elements of N(hk), or . Nugget - represent micro-scale variation or measurement error. Its estimated by (0). Sill - represent the variance of the random field limh(h). Range - the distance at which data are no longer autocorrelated.
Identifying Spatial Autocorrelation Moran I: Geary C: • Moran I (Z value) is • positive: observations tend to be similar; • negative: observations tend to be dissimilar; • approximately zero: observations are arranged randomly over space. • Geary C: • large C value (>>1): observations tend to be dissimilar; • small C value (<<1) indicates that they tend to be similar.
Identifying Local Spatial Associations Local Moran: • significant and negative if location i is • associated with relatively low values in • surrounding locations; • significant and positive if location i is • associated with relatively high values of • the surrounding locations. Local Geary: • significant and small Local Geary (t<0) • suggests a positive spatial association • (similarity); • significant and large Local Geary (t>0) • suggests a negative spatial association • (dissimilarity).
Spatial Regression Spatially autoregressive model Spatial moving average model Semi-parametric model where W1 and W2 are spatial weight matrices, ~ N(0,).
