Research on the Mechanism of Rural Industry Integration Enabled by Digital Countryside under the Background of Rural Revitalization

Digital rural development is an important part of the construction of digital China, and plays an important role in the development of China's rural industry and the realization of rural revitalization strategy. Based on the systematic analysis of the development trend and regional structure of digital countryside, this paper focuses on the study of the heterogeneous impact of digital countryside development on rural industry integration, and explores the mechanism of digital countryside development driving rural industry integration. Based on the provincial panel data from 2011 to 2021, an evaluation index system is constructed to measure the development level of digital countryside and the integration level of rural industry in each region of China using the entropy value method, and the threshold effect and internal mechanism between the two are analyzed using the panel threshold model. The results show that the development level of digital countryside in all regions of China is higher and shows an increasing trend year by year, and there is strong regional heterogeneity. There is a U-shaped relationship between digital rural development and rural industry integration, and there is a significant double threshold effect, the threshold values are 0.084 and 0.109, respectively. Therefore, it is necessary to accelerate the coordination of digital rural construction in various regions of China, fully consider the threshold effect of digital rural construction level in various regions, and establish a diversified driving path for rural industrial integration by combining traditional financial support for agriculture, regional trade opening, urbanization and rural fixed asset investment.
