应对气候变化的农业经济研究前沿与政策实践

气候变化对农业生产造成巨大且深刻的影响，备受社会各界的关注。但是，已有研究呈现碎片化状态，难以反映研究的热点及其政策导向。为厘清应对气候变化的农业经济研究的内核并发挥理论创新和政策引领作用，以中国1992—2020年共1 678篇文献为研究对象，通过文献计量法和内容分析法对其进行分析，在此基础上，剖析理论研究与政策实践的悖离及其成因与对策。结果表明:（1）已有研究构建“气候变化—风险生成—农户避险手段”的理论框架，主要讨论气候变化（外生的）如何影响到农业生产进而造成农户避险手段选择性偏好（内生的）。（2）理论研究目标是增强农户对冲风险能力，政策实践目标是减少气候致灾因子，两者呈现悖离性。为此，应从“政策助推—市场发育—认知响应”三个方面，促进理论与政策的协同发展，并搭建应对气候变化的农业风险管理体系。

Agricultural Economic Research Frontiers and Policy Practice in Response to Climate Change

Research on the impact of climate change on agriculture has attracted much attention, but relevant research is incomplete and it is difficult to reflect the research hotspots and policy orientation. Therefore, in order to clarify the core of agricultural economic research in response to climate change and bring into play the role of theoretical innovation and policy guidance, a total of 1 678 pieces of literature in China from 1992 to 2020 were analyzed by bibliometric method and content analysis method. On the above basis, the conflict between theoretical research and policy practice and its causes and countermeasures were analyzed. The results show that: (1) The existing research has constructed the theoretical framework of “climate change-risk generation-peasant household hedge strategy ”. These studies focus on how climate change affects agricultural production and results in peasants’ preference for hedging strategies. (2) The goal of theoretical research is to enhance the risk hedging ability of peasants while policies are directed at reducing climate hazards. Therefore, the coordinated development of theories and policies should be promoted, and an agricultural risk management system should be built from three aspects of policy boost, market development and cognitive response.
