Abstract: Using spatial accessibility to recognize areas lacking medical resource is the basis of provincial medical panning. From the perspective of time cost, this paper calculates the spatial accessibility by using Two Step Floating Catchment Area (2SFCA), so as to define the relatively poor areas and recognize the areas lacking medical resource. Taking Anhui Province in 2015 as an example, results of this paper show that from the provincial scale, the accessibility is alternately wavy from north to south, and more than 97% of the population can reach the county hospital within an hour, but 1.78% of the population (about 1.09 million people) can't reach the county hospital within 3 hours. However, the distribution of accessibility is not balanced from county scale and town scale.
