    The process and logical mechanism of agricultural production space contraction in mountainous areas based on actor-network theory:A case study of Lishi Village in Longde County, Ni... by CHEN Kunqiu, CHEN Yunya, LIANG Yajia, ZHENG Yuhan

    Published 2025-01-01
    “…[Results] The study found that: (1) The translation of actor networks at different stages, the entry and exit of heterogeneous actors within the networks, and the transformation of the actor networks goals comprehensively contributed to the contraction of agricultural production space through the combined effects of human and non-human actors. (2) During the transformation of the actor network in Lishi Village, the key actor changed from the local government to the young labor force, and the obligatory point of passage (OPP) changed from “returning farmland to forest and grassland” to “developing specialty farming to maximize economic income”. (3) The agricultural production space in Lishi Village has gone through two stages: explicit contraction under the ecological objective and implicit contraction under the economic objective. (4) The contraction of agricultural production space in mountainous areas follows the mechanisms of environmental logic, policy-driven logic, and multi-subject logic. …”
