Demand for Spatial Analysis
Identify the spatial structure of economic and demographic forces (urban core, urban periphery and rural hinterland).
Identify the spatial interactions (linkages) between urban and rural areas.
Evaluate the effects of local amenities on regional development.
Objective: The System Dynamics of Spatial Economy
Questions for Spatial Analysis
Is there any spatial cluster over space?Are spatial observations distributed
randomly over space?Are spatial observations correlated
(autocorrelation)? Is there any spatial outlier? Is there any spatial trend?What is the interaction (statistically and
theoretically) between different variables?How to predict an unknown spatial value at a
specific location?
• Exploratory Spatial Data Analysis Graphic Analysis Geostatistics Spatial Statistics
• Spatial Modeling Gravity models Spatial linear models Space-temporal models Other models
Methodology for Spatial Analysis
China Data Online- The primary data source for China studies
Statistical Database:• Monthly Statistics • National Statistics • Provincial Statistics • City Statistics • County Statistics • Monthly Industrial Data • Yearly Industrial Data • Statistics on Map • Statistical Yearbooks Census Database:• Population Census 1982 • Population Census 1990 • Population Survey 1995,
2005• Province Census 2000 • County Census 2000• Economic Census 2004

Barriers and Challenges
Barriers: Separation of information from different
sources Separation of information from different
fields Separation of research by different
groupsChallenges: Share of data (manipulation of mass data from
different sources and formats) Share of methodology for data analysis Share of knowledge (results from research)
Solution: Spatial Intelligence
An Integration of Information, Methodology and Knowledge supported by Spatial Technology
