Abstract: Independent innovation is an important way for agricultural enterprises to build technical barriers, but there are problems such as long-term, high-risk, etc. It is difficult to achieve Pareto optimality by relying solely on market regulation, and the government's regulatory role must be exerted. Based on this, this article takes 9959 agricultural enterprises as a sample, and uses the SSBM-network DEA model to measure the transformation efficiency of agricultural enterprises’ scientific and technological achievements, empirically examines the impact of independent innovation on the transformation efficiency of scientific and technological achievements, and explores government behavior (government Subsidies and innovation policies). The research results show that: (1) There is an inverted U-shaped relationship between independent innovation and the efficiency of transformation of scientific and technological achievements of agricultural enterprises. (2) Both government subsidies and innovation policies positively regulate the positive impact of independent innovation on the conversion efficiency of scientific and technological achievements when independent innovation does not exceed the threshold. However, innovation policies help alleviate the negative impact of independent innovation on the conversion efficiency of scientific and technological achievements after exceeding the threshold, while government subsidies have not played a corresponding mitigation effect. The research conclusions not only provide evidence of independent innovation activities carried out by agricultural enterprises, but also provide support for the government and agricultural enterprises to optimize independent innovation.

摘要： 自主创新是涉农企业构建技术壁垒的重要途径，但存在长周期、高风险等问题，单纯依靠市场调节难以实现帕累托最优，必须发挥政府的调控作用。基于此，本文以9959家涉农企业为样本，在使用SSBM-网络DEA模型测算涉农企业科技成果转化效率的基础上，实证检验自主创新对科技成果转化效率的影响，并探究政府行为（政府补助与创新政策）的调节效应。研究结果显示：（1）自主创新与涉农企业科技成果转化效率之间存在倒“U”型关系。（2）政府补助与创新政策均正向调节自主创新未超过阈值时对科技成果转化效率的正向影响。但创新政策有助于缓解自主创新超过阈值后对科技成果转化效率的负向影响，而政府补助却未起到相应的缓解作用。研究结论不仅提供了涉农企业开展自主创新活动的证据，还为政府与涉农企业优化自主创新提供了支撑。
