Abstract: Based on relevant literature, a comprehensive evaluation index system for the integration of rural primary, secondary and tertiary industries in Guangdong Province was constructed from two dimensions of behavior and performance, and the entropy method and TOPSIS analysis method were adopted to make a comprehensive evaluation of the integration level of rural industries in Guangdong Province. The results showed that the integrated development level of the primary, secondary and tertiary industries in rural areas of Guangdong Province showed a steady upward trend in general, and the comprehensive scores of each secondary subsystem also showed an overall upward trend, and the closeness degree of TOPSIS ideal points increased year by year, which indicated that the significant effect of integration measures of the primary, secondary and tertiary industries in rural areas of Guangdong Province was remarkable. In order to further promote the integrated development of primary, secondary and tertiary industries in rural areas of Guangdong Province, suggestions were put forward from five dimensions： Comprehensively promoting the prosperity of rural economy, increasing the horizontal and vertical extension of the agricultural industry chain, giving full play to the multi-function of agriculture, promoting the innovative development of agricultural producer services, and building a platform for the integration of innovative industries.
