Research on Spatial Accessibility to Health Service——A Case Study in the Haizhu District of Guangzhou

Based on 2000 Census and primary hospital physician data and the spatial interactive models,this paper assesses the variation of spatial accessibility to primary hospitals in the Haizhu District of Guangzhou. This method is implemented in a GIS environment.The method considers the interaction between doctors and patients and use distance to measure the spatial barrier between them.Specifically,the paper analyzes the sensitivity of results by experimenting with ranges of threshold rank coefficient in the model.Results from the method reveal details of varying spatial accessibility to health service with finer resolution data.Based on this preliminary case study,we recommend the method for use in improving the designation of health service shortage areas.And also this model may be used to help government to make decision.
