Abstract: The combination of agriculture and tourism is an important path of rural industrial integration and an important breakthrough to realize rural revitalization. Based on agricultural and tourism statistics of 31 provinces in China from 1997 to 2019, this paper constructs a panel autoregressive model, and discusses the relationship between agriculture and tourism. On this basis, it uses coupling coordination evaluation model to further explore the internal interaction strength between agriculture and tourism, and summarize the coupling coordination development model. The results show that: (1) there is a stable equilibrium relationship between agriculture and tourism with a significant regional heterogeneity, that is, agriculture and tourism are two-way promotion in eastern and central regions, while agriculture is one-way promotion in western regions. (2) The coupling coordination of agriculture and tourism shows an upward trend, and presents a typical ladder distribution characteristics, that means, eastern regions are higher than central regions, while central regions are higher than western regions. In order to promote integrated development of agriculture and tourism, the paper proposes attaching importance to strategic relationship between agriculture and tourism in concept, strengthening support to integrated development of agriculture and tourism in policy, and adjusting integrated development of agriculture and tourism in accordance with local conditions.
