A static discrete game model is established, and under the assumption that the observable decision outcomes are the equilibrium of participants' games, a mechanism and empirical analysis of decision-making in the dig-ital age agricultural socialization service market are conducted based on the sample data from the China Family Panel Studies. The results show that the decision-making in the agricultural socialization service market is not only an economic choice for profit maximization by various agricultur-al business entities but also an equilibrium of games among market partic-ipants. The scale effect and income effect of agricultural socialization ser-vices have driven the market entry decisions of professional farmers, but the market entry barriers show a significant positive scale preference. In the digital era, the "digital divide" among potential entrants restricts the synergistic effect of digital technology and agricultural technology in the development of the service market. Therefore, in the process of agricultural socialization service market development, it is necessary to focus on digi-tal agricultural socialization service platforms, develop the "financial" function of the service market, enhance the digital literacy of service enti-ties, create a fair competitive environment in the service market, and form a balanced agricultural socialization service system with balanced service supply and demand and effective policies.
