Objective/Meaning The integration of agriculture and tourism is an inevitable requirement to promote the high-quality development of agriculture and tourism. Promoting the integration of agriculture and tourism in the regions in habited by ethnic groups is conducive to rural revitalization and the development of economy and society.

Methods/Procedures Based on the theory of industrial integration, the coupling coordination model of agriculture and tourism was constructed. And the development level of agriculture and tourism industry in Inner Mongolia was evaluated by using the entropy method. Based on the cross-section data from 12 leagues and cities in Inner Mongolia in the recent 11 years, the coupling coordination degree was analyzed, and the restrictive factors were analyzed by using the obstacle degree model.

Results/Conclusions The study found that: (1) the coupling coordination between agriculture and tourism industries in Inner Mongolia has gradually shifted from the initial barely coordinated development to intermediate coordinated development. The difference of coordination degree among the three major regions showed the trend of “expansion-reduction-expansion”, and there were differences in the growth rates between each league and city. With the development of agriculture and tourism industries, the difference between the leagues and cities was gradually narrowing. (2) There was significant difference in the level of coordination between each league and city, which could be divided into three orders, showing the pattern that the more developed the agricultural and tourism industries were, the higher the level of coordination between the two. (3) From the perspective of obstacle degree analysis, the obstacle degree of the two industries changed alternately. Among them, the total power of agricultural machinery, the application amount of chemical fertilizer, the total output value of agriculture, forestry, stockbreeding and fishery, the proportion of agriculture in GDP, the catering corporate enterprise above norm, the total income of the tourism industry and the number of inbound tourists were the main factors hindering the coordinated development of the system. Based on this, the following suggestions were put forward including that: (1) grasping the main factors affecting the coordinated development; (2) coordinating the development degree of various regions, thus to further narrow the gap between leagues and cities; (3) driving the agricultural development and promoting the integration of agriculture and tourism through the high-quality development of tourism.
