城市特征新论

城市本身是一个辩证的对立统一体,以往对城市系统单个特征的认识或强调是片面的,需要从对立统一规律的角度来重新审视城市特征.笔者认为,城市的特征主要有:集聚与扩散作用的共存性及交替主导性、溢出效应与乘数效应的互动性、公共性与经营性的兼容性、多样化与两极分化的并存性、线性关系向非线性关系的递进性等.

A NEW APPROACH TO THE URBAN FEATURES

City itself is the dialectical unity of opposites. Due to the traditional and unilateral knowledge or emphasis on the individual feature of urban system, we must reconsider urban features according to the law of the unity of opposites. In this article, the author holds that the new urban features should include the coexistence and dominant action alternately both agglomeration and diffusion, the dependence on each other for existence both overflowing effects and multiplier effects, the compatibility both public benefit and economic benefit, the coexistence both diversification and polarization, the evolution successively from linear relations to nonlinear relations.
