Producer services are regarded as significant intermediate inputs in the value-added creation process, exerting a crucial impact on the integration of agriculture into the global value chain (GVC). Grounded in OECD AMNE input-output data, the influence of producer services on the position in agricultural GVC was examined using a systematic GMM model. Mechanism tests demonstrate that producer services, through the effects of resource allocation and economies of scale, were utilized to enhance production efficiency and reduce trade costs, thereby promoting the elevation of the agricultural GVC position. Concerning segmented producer services, inputs such as professional and scientific-technical services, as well as financial and insurance services, significantly elevate the position in the agricultural GVC. Additionally, transportation and storage services exert a certain positive influence. However, information and communication services have a negative impact on forward participation and a positive impact on backward participation in the agricultural GVC. Hence, there is a need to strengthen the utilization of agricultural information technology in the upstream of the agricultural industry chain. The findings provide worthwhile policy insights for promoting agricultural competitiveness of developing economies, including China.
