In order to analyze the impact of the iterative mechanism of rural industries on the development status of tourism-oriented rural industries under the goal of common prosperity， a coupling and coordination analysis of tourism-oriented rural industries under the goal of common prosperity is proposed. After analyzing the concepts of the goal of common prosperity and the iterative mechanism of tourism-oriented rural industries， this method constructed a comprehensive development level measurement model for the iterative mechanism of tourism-oriented rural industries and an evaluation index system for the comprehensive development level of tourism guided rural industries， and assigned weights to each index using the coefficient of variation method to calculate the comprehensive index of the iterative development level of rural industries. Based on this index， the synergistic development status of tourism-oriented rural industries and the goal of common prosperity were evaluated through coupling and coordination analysis. The development and changing characteristics of tourism-oriented rural industries and the goal of common prosperity were further studied based on the scissors difference model. The empirical results show that from 2015 to 2023， the comprehensive evaluation index of rural industries and common prosperity in the study area has significantly improved， proving the effectiveness and stability of the iterative mechanism. The tourism-oriented rural industry interacts closely with the goal of common prosperity， with increasing coupling and deepening mutual influence year by year. With the advancement of the iterative mechanism， the coordination degree between these two has increased from barely coordinated to highly coordinated， and a positive interaction is evident. However， the gap between the development rate of rural tourism and common prosperity is widening， and it is necessary to strengthen coordination and social participation.
