Abstract: Deeply understanding the industrial linkage between industry and agriculture and the interaction between rural and urban area is important to promote the integration process of rural and urban areas. The compilation of rural-urban input-output model is a powerful tool to quantitatively analyze the economic linkage between the urban and rural areas. The agricultural sector in 2002 input-output table was split into 23 sectors and a rural-urban input-output model of 77 sectors was compiled. In the meanwhile, diffusion coefficient, inducing coefficient and sensitivity coefficient were calculated in the planting sectors and livestock sectors. The results were showed as follows. Firstly，the diffusion coefficient and sensitivity coefficient were in line with the agricultural development of China. Secondly，the results of inducing coefficient explained the relationship of the consumption, investment and export in the planting sectors, and the development of the production of food crops depended on consumption; Thirdly，export had an important impact on the production of cotton and hemp，and investment promoted the production of the forestry and timber. Finally，the results verified the reliability of the model.
