Research on the digital economy promoting the high-quality development of trade in the central and western regions under the background of big data technology

In order to improve the effect of the digital economy in promoting the development of trade in the central and western regions, this paper combines the intelligent digital economy identification algorithm to construct a trade analysis model, and proposes a collaborative cache strategy in the hybrid mobile opportunistic network scenario. By placing the AP access point at the center of the network, the disadvantage of relying only on node mobility for opportunistic data access is effectively compensated. For different communication scenarios, this paper divides the data transmission stage into D2D communication stage and D2A communication stage according to different relay choices in the data transmission process. Moreover, this paper conducts modeling analysis on them respectively, and discusses the access delay of nodes to data in the network. Finally, this paper verifies that the algorithm in this paper has a certain effect through experi-mental research, and puts forward suggestions for promoting the high-quality development of trade in the central and western regions.
