Based on grey relational model and relevant data during 2003- 2012,this paper performs an empirical analysis of the internal structure of agricultural economy and the internal structure of animal husbandry in Inner Mongolia. The results show that animal husbandry and farming are two important sectors of agricultural economy in Inner Mongolia,and within animal husbandry,the influence of dairy cow,mutton,beef and goat wool production is most obvious. Based on this,this paper puts forth the following recommendations: stabilizing the dominant position of farming and animal husbandry in the agricultural economy; continuing to adjust and optimize the internal structure of agricultural economy; reasonably and guide the development of various industries within animal husbandry.展开更多
