城市群功能分工对区域协调发展的影响研究--以京津冀城市群为例

Study on the Influence of Functional Division of Urban Agglomerations on Regional Coordinated Development——Taking Beijing-Tianjin-Hebei Urban Agglomeration as an Example

基于已有的研究成果,采用计算不同城市不同行业的区位商的方法进一步细分生产性服务功能和生产制造功能在城市群内部的空间布局,更加准确地了解城市群功能分工的发展状况。并以京津冀城市群为例,发现以北京市和天津市为中心城市组与以河北省各地级市为边缘城市组的功能分工显著;北京市主要发挥生产性服务功能,天津市和河北省各地级市主要发挥生产制造功能;北京市的生产性服务功能负担过重,天津市和河北省各地级市的生产制造功能冗余;本文结论得出京津冀城市群尚未真正形成错位发展、功能互补、多中心协同的空间分工格局,不利于持续推进区域协调发展。京津冀城市群亟需基于不同城市的功能定位,进一步优化产业分工格局。

Based on the existing research results,the spatial distribution of productive service functions and manufacturing functions in urban agglomerations is further refined by calculating the location quotient of industries in different cities,so the development status of functional division of urban agglomerations is more accurately understood.Taking the Beijing-Tianjin-Hebei Urban Agglomeration as an example,it is found that the functional division between the central urban groups of Beijing and Tianjin and the marginal urban groups of Hebei is significant;Beijing mainly plays the role of productive service,Tianjin and Hebei play the role of manufacturing;Beijing’s productive service function is overburdened,and the manufacturing functions of Tianjin and the cities in Hebei are overlapped.It is concluded that Beijing-Tianjin-Hebei Urban Agglomeration has not really formed a spatial division pattern of dislocation development,functional complementarity and multi-center coordination,which is not conducive to continuously promote regional coordinated development.Beijing-Tianjin-Hebei Urban Agglomeration needs to further optimize the pattern of industrial division based on the functional positioning of different cities.
