中文摘要：

经济物理学已经发展成为一门新的交叉学科，物理学的许多重要理论成果被运用到经济研究中，极大地促进了经济学的发展。经济系统与物理系统具有共同的基点，共同服从某种普适的规律，运用经济物理学的研究方法，以电磁场理论和模型为研究工具，构建城市场理论及其模型研究城市间相互作用的机理和效应，具有科学合理性，拓展和提升了现有研究的视野和高度。

英文摘要：

In recent years, many of the important theoretical achievements of physics have been used to econom- ic research,which have enormously promoted the development of economics. In this paper, the econophysics re- search method have been well adopted while the Theory of City Fields have been comparatively demonstrated based on Electromagnetic Fields Theory and Model, which have scientific rationality and have promoted and developed the vision and height of existing research field of interaction between cities.
