Using concentration coefficient, efficiency advantage index and scale advantage index to analyze the concentration degree and advantage degree, it is found that Zhongning wolfberry, Xiji potato, Wuzhong dairy, Lingwu red jujube and Helanshan grape in Ningxia are in good condition Lanshan grape have high degree of specialization and concentration. The effect of industrial cluster has been highlighted or is becoming prominent, and the competitiveness of industrial cluster has been formed in China.
