城市群内部城市间竞争和合作对城市经济发展的影响——基于空间溢出效应对长三角城市群的实证检验

Influence of Competition and Cooperation between Intercity of Urban Agglomeration on Urban Economic Development——Empirical Test on Urban Agglomeration of Yangtze River Delta Based on the Perspective of Spatial Spillover

在城市群发展过程中,城市间的竞争与合作是并行的,城市间的关系对城市自身和城市群整体经济发展都具有重要影响。基于空间溢出效应构建空间计量模型,选取长三角城市群扩容后的26个城市为样本,分析城市间竞争关系和合作关系对城市及其他城市经济发展的影响,结果表明:竞争对本地经济发展具有促进作用而对其他城市经济发展的溢出效应为负,合作对本地和其他城市经济发展均产生正向影响。在以经济绩效为核心的地方政府考核机制下,竞争的负溢出效应与合作的正溢出效应导致地方政府间的竞争意愿大于合作意愿。要更好地发挥上级政府的作用,在从整体上规划好城市群发展的同时,将"城市间合作"作为对各城市政府及官员考核的重要内容;同时,要建立有效的常态化的城市间经济合作机制,通过产业分工强化城市间的经济合作关系和行为。

In the process of urban agglomeration development,the intercity competition and cooperation are parallel,and the relationship between the cities has important impact on urban development and the overall economic development of urban agglomerations.Based on spatial spillover effect to construct spatial econometrics model,we choose the data of 26 cities in the Yangtze River Delta urban cluster as sample,analyze the influence of the intercity competition and cooperative on the cities and the economic development of other cities.Empirical results show that competition has a positive effect on the level of local economic development but its impact on other cities is negative,and that the effect of cooperation on the level of local economic development is positive and its impact on other cities is also positive.Under the examination mechanism taking economic performance as the core of local government,the negative spillover effect of competition and positive spillover effect of cooperation make the willingness of the competition be greater than that of cooperation among local governments.Therefore,these areas should bring governmental role into fully play,take ＂intercity cooperation ＂ as the important content of the examination of each city government and officials while making good overall plan for urban agglomerations,meanwhile,set up effective and normalized intercity economic cooperation mechanism and strengthen intercity economic cooperation relation and behavior by industrial division.
