本文基于协同学理论对海水稻技术扩散系统进行分析，通过在传统推广系统中加入农业企业主体变量并建立以其为核心的多主体协同扩散模型，发现新的扩散系统具有稳定性和鲁棒性。进一步通过研究多主体协同扩散的动力机制，提出构建中国情境下，海水稻技术创新扩散的战略驱动力和市场拉动力“双轮驱动”模型，以解决我国海水稻持续扩散的动力机制问题，为我国政府制定海水稻技术创新扩散政策提供了理论基础。

The spread of sea rice (salt-tolerant rice) technology has great strategic significance for alleviating the trend of arable land area and grain yield in China. The spread of sea rice in the existing agricultural technology diffusion system has system instability and diffusion time lag. Based on the theory of synergy, this paper analyzes the diffusion system of sea rice technology. By adding the main body variable of agricultural enterprise and establishing the multi-agent co-diffusion model with its core as the core, it is found that the new diffusion system has stability and robustness.. Furthermore, by studying the dynamic mechanism of multi-agent co-proliferation, this paper proposes to construct a strategic driving force for the diffusion of sea rice technology innovation and a “two-wheel drive” model of market power in China, in order to solve the dynamic mechanism of sustainable rice diffusion in China as well formulate a policy for the diffusion of sea rice technology innovation.
