Research on the Spatial Pattern Evolution and Optimization Control of the Harbin-Changchun Urban Agglomeration from the Perspective of Administrative Divisions
With the advancement of urbanization,the problems of administrative division setting restricting the development of cities and urban agglomerations in some regions have been gradually exposed.Administrative division adjustment has become a policy tool for governments at all levels to solve urban problems,but the state has put forward higher requirements for the scientific nature and necessity of administrative division adjustment.It is helpful to improve the overall and systematic nature of administrative division to study the problems of administrative division existing in cities from the scale of urban agglomeration and to optimize the pattern of administrative division as a whole.Taking Harbin-Changchun Urban Agglomeration as the research area,this paper uses the spatial field energy model to analyze the evolution characteristics of the spatial pattern of urban agglomeration from 2010 to 2020,and draws the following conclusions:(1)the regional development polarization of Harbin-Changchun Urban Agglomeration is serious,the development gap between Changchun and Harbin and other cities is further expanded,and the development of most cities is in decline;(2)the overall field energy of Harbin-Changchun Urban Agglomeration is characterized by"high in the middle and West,low in the East",the"dual core"structure of Changchun and Harbin is prominent,central and western regions have formed urban development and contact networks,and the level of urban economic development and contact in the eastern and northern regions is relatively low;(3)in the hinterland of central cities,Changchun and Harbin account for about 60％of the hinterland of urban agglomerations,and the other nine central cities account for about 40％of the hinterland,of which Suihua,Siping and Songyuan only account for about 1％of the hinterland of urban agglomerations,(4)due to the"siphon"effect of Changchun and Harbin,the prefecture level cities of Jilin,Siping,Songyuan,Liaoyuan and Suihua are underdeveloped,and the hinterland of county-level administrative regions has been seriously attacked.Based on the analysis results,this paper puts forward five optimization suggestions of administrative divisions,including promoting the"smart contraction"of administrative regions,adjusting the boundaries of county-level administrative divisions,eliminating the"enclaves"of administrative regions,establishing municipal districts in the core circles,and establishing county-level cities in the less radiating circles.These adjustments aim to optimize the spatial pattern of the Harbin-Changchun urban agglomeration.
