生产性服务对农业全球价值链分工地位的影响

生产性服务是增加值创造过程中重要的中间品投入，对农业嵌入全球价值链有重要影响。本文基于OECD AMNE投入产出数据，运用系统GMM模型考察生产性服务对农业全球价值链分工地位的影响。机制检验表明，生产性服务通过资源配置效应和规模经济效应来提高生产效率、降低贸易成本进而促进农业全球价值链分工地位的提升。从细分生产性服务来看，专业与科学技术服务、金融与保险服务投入均能显著提高农业全球价值链分工地位，运输和储存服务对农业全球价值链分工地位有一定正向影响，而信息和通讯服务对农业全球价值链前向参与度有负向影响，对后向参与度则有正向影响，因此需要加强农业产业链上游对农业信息技术的利用。本文研究结论为推动包括我国在内的发展中经济体的农业竞争力提升提供了值得借鉴的政策启示。

Influence of Producer Services on the Position in Agricultural Global Value Chain

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 is examined using a systematic GMM model. Mechanism tests demonstrate that producer services, through the effects of resource allocation and economies of scale, are 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.
