摘　　要：厘清中国区域经济发展中多样化的空间相互作用,对于探索新时期区域协调发展的新理念具有重要意义。根据增长极理论和中心地理论构建空间计量模型,以中国260个地级及以上城市为研究对象,研究不同收入水平城市间的同群效应,从新的视角解释区域协调发展的内在动力。研究发现:高收入城市通过正向同群效应对邻近中等收入城市的经济增长产生了带动作用,通过负向同群效应对邻近陷阱城市的经济增长产生了抑制作用,中国城市之间未完全发挥自上而下的辐射带动作用;中等收入城市对高收入城市的经济增长、陷阱城市对中等收入城市的经济增长均具有正向同群效应,中国城市之间存在着自下而上的经济增长促进作用;同等收入水平城市间的经济增长通过正向同群效应相互促进。进一步的作用机制检验表明:同群效应的产生更多是源于分权体制下的"标尺竞争",其中学习和竞争机制在不同收入水平城市内部的作用效果存在明显异质性。最后,从实施多中心空间战略、构建新型城市合作模式、加强基础设施建设、完善政绩考核体系等方面提出了实现区域协调发展的政策启示。Clarifying the diversified spatial interaction in China’s regional economic development is of great significance to explore the new concept of regional coordinated development in the new era.This paper constructs the spatial econometric model based on growth pole and central place theories,and studies the peer effects of urban areas in different income levels taking 260 prefecture-level cities in China as the research object,and explains the internal motive force of regional coordinated development from a new perspective.The results show that:(1)Highincome cities have a driving effect on the economic growth of neighboring middle-income cities through positive peer effects,and have a dampening effect on the economic growth of neighboring trap cities through negative peer effects.The top-down radiation action between Chinese cities is not fully utilized.(2)Middle-income cities have positive peer effects on the economic growth of high-income cities,and trap cities have positive peer effects on the economic growth of middle-income cities,and there is a bottom-up economic growth promotion between our cities.(3)Economic growth between cities at equal income levels is mutually reinforced by positive peer effects.Further study finds that peer effects are largely due to the yardstick competition under decentralized fiscal system,and there is a significant heterogeneity in the effects of learning and competition mechanisms within cities with different income levels.Finally,the policy enlightenment of realizing regional coordinated development is put forward from the aspects of implementing a multi-central space strategy,building a new type of urban cooperation model,strengthening the infrastructure construction,and improving the performance evaluation system.
