摘　　要：城市群是提高地区经济增长和深入实施区域协调发展战略过程中的重要载体。本文尝试结合“新”新经济地理学模型和基于agent计算经济学对多重异质性下城市差异化对企业和人口的空间演化影响进行研究,建立了一个企业生产效率与规模、居民工资等多重异质性的两区域空间经济模型对城市间人口和企业迁移进行动态模拟以研究空间经济演化过程。结果表明:(1)无论是否存在市场进入和退出机制,小城市内部工业产品的差异性越大,越有利于企业和人口向小城市迁移,企业和人口倾向于分散。但是存在市场机制能提高城市内产品差异化对人口和企业迁移的吸引力。(2)城市群中小城市要更多的企业和人口,需要继续鼓励创新生产差异化产品,使城市内的产品更加多样化和差异化。(3)为了使城市内产品差异化发挥更大的作用,整个地区需要更加健全企业进入和退出的市场机制,使得有利可图的资本可以进入市场,同时亏损的企业能够退出市场或者转型升级和改制。City clusters are an important carrier in the process of improving regional economic growth and deepening the implementation of Strategy for Coordinated Regional Development.This paper attempts to combine the"new"new economic geography model and agent-based computational economics to study the impact of urban differentiation on the spatial evolution of enterprises and population under multiple heterogeneity,establish a two region spatial economic model with multiple heterogeneity of enterprise production efficiency and scale,residents'wages,etc.,and integrate agent-based modeling to dynamically simulate the migration of population and enterprises between cities to study the spatial economic evolution process.The results indicate that:(1)regardless of whether there is a market entry and exit mechanism,the greater the difference in industrial products within small cities,the more conducive it is for enterprises and populations to migrate to small cities,and enterprises and populations tend to be dispersed.However,the existence of market mechanism can improve the impact of product differentiation on population and enterprise migration in cities.(2)Small and medium-sized cities in city clusters need more firms and populations,and they need to continue to encourage innovation and entrepreneurship to produce differentiated products,making the products within the city more diverse and differentiated.(3)In order to make product differentiation play a greater role in the city,the whole region needs to improve the market mechanism for enterprises to enter and exit,so that profitable capital can enter market and the loss making enterprises at the same time,can exit the market or transform,upgrade and reform.
