Abstract：The wholesale market serves as the primary hub for the distribution of agricultural products ，and its technological progress is the fundamental driving force for the realization of a bigger and stronger agricultural product processing and circulation industry. At the moment，the digital economy is thriving，therefore it is critical to understand how it contributes to the technological advancement of the agricultural wholesale market. Based on the provincial data of China from 2013 to 2019，the SBM- GML index is used to measure the technological progress rate of the wholesale market of agricultural products ，and the entropy method is used to measure the development level of digital development and e- commerce channel for agricultural products respectively. The fixed effect model and threshold regression model are used to investigate the impact and the nonlinear impact effect of digital development on the technological progress of the wholesale market of agricultural products ，and the intermediary effect model is used to explore the intermediary role of the e-commerce channel. The results show that ：technology advancements in the wholesale market of agricultural products primarily increase total factor productivity ， and digital development has the potential to significantly accelerate this advancement ；the development of e- commerce channel plays an intermediary role in the process of digital development affecting technological progress ，which to some extent weakens the promotion effect of digital development，owing to the channel diversion and channel barrier effects formed by e- commerce development；and the impact of digital development level on technological progress has a double threshold effect ，when the two thresholds are crossed，the driving force of digital development on technological progress shifts from medium to strong and then to weak. The development of the wholesale market of agricultural products should comply with the needs of the digital era ，fully exploit to the hub advantages while responding to the policy guidance of the digital economy ，and respond to the rigid landing of e-commerce with flexible integration measures. By upgrading the digital service function ，the dual-channel circulation function and the cold- chain storage function ，the wholesale market would gradually form the channel synergy and realize the digital transformation and the efficiency improvement of the supply chain.
