摘　　要：通过梳理城市经济学理论模型和实证方法的脉络,本文尝试厘清当前的系列前沿问题,其中包括:城市空间结构从单中心演变为多中心、城市发展从单一均衡到城市体系(城市间)均衡、微观集聚模式从同质性主体转变为异质性主体,以及实证方法逐渐从简约式估计演进为结构式估计。本文首先概述城市空间结构从单中心向多中心演变的机制、驱动因素以及经济社会效应;其次,阐释从单个城市均衡到城市间均衡的演变过程,探讨城市体系演变的驱动因素和相关议题;再次,剖析最新的异质性主体集聚理论,探讨异质性集聚的驱动因素和研究进展;最后,在实证方法上,概述从简约式估计到结构式估计转变的背景和研究进展。未来研究中,可关注远程办公、创新集群以及都市圈(城市群)一体化等对城市发展的影响。China's economy is moving forward and striving for high-quality development,and clarifying the evolution of urban economics is essential to grasping the logic of urban development and telling China's story.In reality,several cutting-edge issues in urban economics have emerged,such as the transformation of urban spatial structure from monocentric to polycentric pattern,the industrial division of labor and functional positioning across large,medium,and small cities,and the sorting and selecting effects of heterogeneous agents(labor,enterprises,and industries)among different cities.Existing theories have not provided effective support or perfect explanations for these new phenomena.Reviewing the evolution of urban economics,this paper finds that spatial general equilibrium models have delved deeper,but there are still problems of overly rigid assumptions,an inability to effectively respond to reality,and a lack of complementarity between theory and reality.Specifically,urban economics has evolved from the Alonso-Mills-Muth(AMM)model to the Rosen-Roback model,and then to heterogeneous agents'agglomeration and quantitative spatial equilibrium models,consistently focusing on the spatial agglomeration of cities,and studying the flows and distribution of people and economic activities among cities.A series of frontier issues in urban studies have emerged.Therefore,to relax the assumptions of homogenous space,transportation costs,and competitive equilibrium,more reasonably explain the location choices of urban micro-agents,and apply more scientific methods to study diversified real-world problems,this paper summarizes the latest theories and methods in urban economics and looks ahead to future research directions.This paper focuses on four major frontier issues in urban economics.The first is the evolution of spatial structure within cities.In existing literature,measuring spatial structures based on the flow of factors like population or land serves as a research foundation,and the comprehensive analysis of the functiona
