Results showed that the developments were unbalanced among different agricultural standardization demonstration zones. Among the examined regions, Hanshou County, Dingcheng District, and Anxiang County were ranked pretty high with the comprehensive benefit scores of 0.902 5, 0.331 5, and 0.320 6 respectively; while Jin County, Linli County, and Li County were ranked at the bottom with the comprehensive benefit scores of -0.374 4, -0.365 2, and -0.351 4 respectively.
