中心城市经济辐射能力差异比较研究

A Comparative Study on Economic Radiation Ability of Heart City

近年来,区域经济发展问题成为我国经济发展中的一个战略问题,受到中央和地方的广泛关注和重视。区域经济发展的质量与速度在很大程度上取决于区域内中心城市的辐射扩散功能。运用动态脉冲函数模型与时间序列收敛模型分别测算上海与北京的经济辐射能力,研究表明:上海的经济辐射能力远大于北京,造成这一差异的原因是多方面的,如城市规模、经济腹地实力、产业结构关联程度、区域一体化程度,等等。长三角地区的发展模式为其他区域经济发展战略乃至全国区域协调发展战略提供了启示。

In the recent years,regional economic development has been a strategy problem in our country,receiving broad attention from local government to central government.Regional economic development speed and quality are decided by the extent of radiation function of heat city in region.In the paper,dynamic impulse response model and method of time series are used to calculate the radiation ability.The result indicates that radiation ability of Shanghai is stronger than Beijing.The reasons are various,such as the scale of city,economy hinderland＇s strength,the relationship of industry structure,and so on.＂Changjiang triangle＂ development model brings enlightenment to the improvement of other regional economic development strategies as well as of nationwide.
