摘要：

Two models of agricultural research and technology diffusion are described and contrasted. The central source of innovation model frequently underlies the theories and rhetoric of agricultural research and extension institutions. The multiple source of innovation model places agricultural research and diffusion processes in the historical, political, economic, agroclimatic, and institutional context in which technological change takes place. The paper discusses the evidence and reasons for the dominance of the central model and reviews the significance of the multiple source model for agricultural research policy. © 1990.
