Research on the urbanization evolution characteristics and action mechanism of shrinking cities in the three provinces of Northeast China
Urban shrinkage is a process-phenomenon-problem comprehensive concept of the continuous outflow and factor outflow effect coupling of development factors such as popula-tion,capital,factories and enterprises,which has brought great impact on the traditional"growth scenario simulation"urbanization development model.The specific impact and its internal mechanism have become the key scientific problems to be solved in the high-quality develop-ment of new urbanization and the practice of urban regional planning in the new era.Based on this,this paper makes an empirical analysis on the three provinces of Northeast China based on the comparative inductive analysis method(shrinking cities and non-shrinking cities,different development stages and different development types of shrinking cities).The results show that:(1)The urbanization development of shrinking cities in the three northeast provinces has the characteristics of stage,type and spatial heterogeneity,and there is an obvious shrinking effect of urbanization;the urbanization level and its subsystem urbanization level show the development and evolution characteristics of"non-shrinking cities＞shrinking cities,early-shrinking cities＞late-shrinking cities＞mid-shrinking cities,resource-dependent shrinking cities＞comprehensive shrinking cities＞siphon-type shrinking cities＞location-constrained shrinking cities,axis+core-periphery";(2)Shrinking cities are due to the relative or absolute decline of their own"de-velopment capacity",and inhibits the driving force of urbanization development—hinder the con-vergence of population and raw materials in surrounding radiation rural areas,and reduce urban input-output efficiency in the process of urbanization,making its urbanization development grow slowly and showing the above-mentioned development characteristics.However,it also leads to the paper's reflection on whether the existing urbanization level and its measurement methods based on"growth simulation"are used in shrinking cities.
