Study on the influence mechanism and spatial difference of high-quality development based on e-commerce technology on the resilience of county economy

In the context of the vigorous development of the digital economy, the impact of e-commerce on the resilience of the county economy has attracted much attention. From the perspective of system theory, this paper constructs the theoretical analysis framework of "e-commerce - county economic resilience", and deeply explores its influence mechanism and spatial differences. The study found that e-commerce can improve the resilience of county economy by expanding the market, optimizing the industrial structure, promoting employment and entrepreneurship, and enhancing the ability to resist risks. Based on the panel data of counties from 2010 to 2020, a spatial econometric model was constructed and the empirical test showed that the agglomeration of e-commerce industry had a significant positive impact on the resilience of county economy and there was a spatial spillover effect. The agglomeration effect was the strongest in the eastern region, followed by the central region, and the weakest in the western region. The case study of Guanzhong region further verifies that the development of e-commerce can significantly improve the resilience of county economy, and innovation-driven and job opportunities expansion play an important intermediary role. Therefore, all localities should formulate e-commerce development policies according to local conditions and strengthen regional cooperation, so as to fully release the enabling potential of e-commerce for the resilience of county economy and promote the high-quality development of regional economy.
