Abstract: Based on the connotation of industrial integration, taking the Yellow river basin as an example, the index system of integration of rural primary, secondary and tertiary industries was constructed from five levels of rural industrial chain extension, agricultural multi-function expansion, rural service industry, economic benefit and social benefit. The entropy method was used to measure the level and spatial difference characteristics of rural industrial integration in the Yellow river basin. Panel data from 2012 to 2019 were collected to test the influencing factors of rural industrial integration level using dynamic GMM model. The results showed that the level of rural industrial integration in the Yellow river basin had been rising steadily year by year from 2012 to 2019, and the development trend was good. The development level of the middle and lower reaches of the Yellow river basin were higher than that of the upper reaches of the Yellow river basin, and there was an obvious spatial difference. Residents' consumption demand, rural land transfer and rural environmental quality had a significant positive effect on the integration level of primary, secondary and tertiary industries in the Yellow river basin, while rural manpower, technology, infrastructure construction and financial support need further development space. Therefore, some corresponding countermeasures and suggestions were put forward for rural industrial integration.

Key words: Yellow river basin, rural industrial integration, entropy method, GMM model
