摘　　要：通过引入物理学中“场”的概念,建立了知识扩散场,以探讨知识扩散的梯度、散度以及知识扩散的规律———供求平衡原则和梯度最小原则;随后构建了知识扩散场图,并以知识和资本在空间上的高度集聚和有效组合形成的规模效应为例说明知识扩散场在城市中的应用。研究表明,知识和资本在空间上的高度集聚和有效组合必然会产生质的飞跃,形成规模效应,同时集聚的能量又必将形成巨大的场效应,对其周边地区产生强烈的辐射作用。By introducing the concept of field in physics, the field of knowledge diffusion was set up to explore the gradient and divergence of knowledge diffusion field, and the laws of knowledge diffusion--the principle of supply-demand equilibrium and gradient minimization. Then the map of knowledge diffusion field was introduced, and an example of scale effect of knowledge and capital by highly clustering and effectively combining in space was provided to illustrate the application of knowledge diffusion field in cities. The results show that qualitative change is inevitable and scale effect will occur if knowledge and capital are highly clustered and effectively combined, and the energy from clusters will cause huge field effect, producing strong radiation function to the areas around.
