智慧城市建设通过集聚效应促进经济增长

Smart City Construction Enhances Economic Growth by Agglomeration

智慧城市建设旨在运用先进的信息技术优化政府对于生产的监管和公共服务的供给,从而为经济发展提供良好的制度支持。良好的制度环境将吸引生产要素集聚,从而通过集聚效应推动经济增长。本文利用中国2004-2017年中国292个地级市面板数据,利用双重差分模型考察了智慧城市建设对集聚和城市经济增长水平的影响。结果表明,智慧城市政策显著促进了经济集聚、推动了经济增长,这种促进作用随着城市自身的集聚水平的上升而下降。

The purpose of smart city construction is to optimize the government's supervision of production and the supply of public services by adopting advanced information technology,so as to provide institutional support for economic development.A good institutional environment will attract the agglomeration of productive factors,enhancing economic growth through agglomeration effect.Using a panel data of China's 292 prefecture-level cities from 2004 to 2017,this paper examines the impact of smart city construction on agglomeration and urban economic growth by difference-in-difference model.The results show that the smart city policy has significantly promoted economic agglomeration and economic growth,and the effects will decline as the city's agglomeration level rises.
