Abstract:

Ward system clustering method is a clustering method using deviation square method for calculating distance. This paper
clusters the net income of rural residents in the various regions in China with Ward system clustering method, uses Matlab simulation
to establish system clustering tree, clusters various regions into different region classes, and provides the necessary decision support for
the next research work.

Key words: Ward system clustering method, system clustering tree, inconsistent coefficient, the per capita net income of rural
residents
