| The coordinated development of Beijing,Tianjin and Hebei is an important part of the national strategy,and the coordinated development of urbanization in the region has become an important part of it.The exploration of the coordinated development of urbanization in Beijing-Tianjin-Hebei region contributes to the effective support for the implementation of Beijing-Tianjin-Hebei coordinated development strategy.Since entering the new era,the problems in the urbanization development of Beijing-Tianjin-Hebei region have changed from the initial low level of development to the uncoordinated development now.The imbalance of urbanization development in Beijing-Tianjin-Hebei region is mainly manifested in two aspects: one is "the imbalance among the internal elements of urbanization",and the other is "the imbalance in the development of urbanization among regions".The research on the coordinated development of urbanization in Beijing-Tianjin-Hebei region is helpful to effectively support the implementation of Beijing-Tianjin-Hebei coordinated development strategy.However,the academic research on the coordinated development of urbanization is slightly one-sided and lack of logic and systematicness.In order to make up for the above shortcomings,in this dissertation,the measurement index system of coordinated development of urbanization is constructed on the basis of deconstructing the connotation of coordinated development of urbanization.Then,the index system is combined with quantitative research and spatial analysis to analyze the coordinated development level,spatiotemporal differentiation characteristics,dynamic evolution trend and influencing factors of urbanization of 13 cities in Beijing-Tianjin-Hebei region.Finally,according to the above research content,the dissertation puts forward the countermeasures for the coordinated development of urbanization in Beijing-Tianjin-Hebei region.The main work and conclusions are as follows:(1)The measurement index system of coordinated development of urbanization is constructed.This dissertation deconstructs and explains the connotation of the coordinated development of urbanization from the five dimensions of population urbanization,economic urbanization,land urbanization,ecological urbanization and social urbanization,and analyzes the interaction mechanism among the above five subsystems.On this basis,the framework of "measurement index system of coordinated development of urbanization" is preliminarily constructed.In order to enrich the content of the index system and reflect the "government effect" in the process of urbanization,this dissertation introduces the "responsibility analysis method" and expands the content of the initially constructed index system framework combined with the existing references.Finally,the measurement index system of coordinated development of urbanization is formed,which includes 5 first-level indicators,16 second-level indicators and 46 third-level indicators.(2)The coordinated development level of urbanization in Beijing-Tianjin-Hebei region is measured.In this dissertation,13 cities in Beijing-Tianjin-Hebei region are selected as the research object.According to the "measurement index system of coordinated development of urbanization",the "combination weighting method" and "coupling coordination model" are used to measure the development level of urbanization subsystem,urbanization comprehensive development level and urbanization coupling coordination level of 13 cities in Beijing-Tianjin-Hebei region from 2009 to 2017(five investigation periods: 2009,2011,2013,2015,2017).The results show that the development index of each subsystem of urbanization in Beijing-Tianjin-Hebei region shows an upward trend as a whole.The Beijing-Tianjin area,the coastal area of eastern Hebei and Shijiazhuang,the capital of Hebei Province,basically fall within the scope of high-level and high-level development areas.The comprehensive development level and coupling coordination level of urbanization in Beijing-Tianjin-Hebei region also show an upward trend,and the leading position of Beijing-Tianjin region,eastern Hebei coastal area and Shijiazhuang,the capital of Hebei Province,is more prominent.(3)The spatiotemporal differentiation and dynamic evolution of the coordinated development of urbanization in Beijing-Tianjin-Hebei region are analyzed.Based on the measurement results of the coordinated development level of urbanization in Beijing-Tianjin-Hebei region,"relative development rate(Nich)" is introduced to refine the spatiotemporal variation of the coordinated development of urbanization,"exploratory spatial data analysis(ESDA)" is introduced to explore its spatial agglomeration characteristics,and "nonparametric kernel density estimation model(KDE)" and "weighted gravity method(CGM)" are introduced to investigate its spatiotemporal evolution trend.The results show that: in the time series,the inflection point of the coordinated development level of urbanization in Beijing-Tianjin-Hebei region appears from slow to fast from 2013 to 2015;in space,it shows the phenomenon of decreasing successively in Beijing-Tianjin area,the capital of Hebei Province,eastern Hebei coastal area and other areas of Hebei Province.The coordinated development level of urbanization in Beijing-Tianjin-Hebei region shows certain characteristics of spatial agglomeration in the whole region,and the spatial agglomeration of each region is becoming more and more obvious.meanwhile.It has significant characteristics of local spatial agglomeration.The local spatial distribution in 2017 is as follows: Beijing-Tianjin area,Shijiazhuang,the capital of Hebei Province,Langfang,Qinhuangdao,Tangshan and Cangzhou in the eastern coastal areas show(high-high agglomeration).Other cities in Hebei show(low-low agglomeration).The coordinated development level of urbanization in Beijing-Tianjin-Hebei region is increasing year by year,along with the trend of widening gap.The "strong polarization effect" with Beijing-Tianjin as the core leads to the unbalanced development of urbanization in the region becoming more and more serious.(4)The factors affecting the coordinated development of urbanization in Beijing-Tianjin-Hebei region are analyzed.In order to explore the causes of the difference in the level of coordinated development of urbanization in Beijing-Tianjin-Hebei region and the causes of temporal-spatial differentiation and evolution,this dissertation constructs a theoretical analysis framework of the factors affecting the coordinated development of urbanization,selects indicators from the internal and external factors of the urbanization system,and estimates the action direction,significance level and spatial effect of the influencing factors by using "fixed effect model(FE)" and "spatial lag model(SLM)".The results show that economic development has an obvious effect on the coordinated development of urbanization in Beijing-Tianjin-Hebei region,but the radiation effect of Beijing-Tianjin region on the economic development of the surrounding areas is not obvious;the core status of population urbanization is not prominent and there is still a high degree of dependence on land finance in the region;the contradiction between the diffusion of eco-environmental pressure and eco-environmental governance restricts the coordinated development process of regional urbanization.There is a serious imbalance between regions in the allocation of public resources,which limits the coordinated development of regional urbanization to a great extent,and the development of urbanization has the current situation of "strong government and soft market".Strong government intervention in various regions is the root cause of not forming a unified market-oriented environment.(5)The control measures for the coordinated development of urbanization in Beijing-Tianjin-Hebei region have been conceived and judged.Starting from the connotation of the coordinated development of urbanization,this dissertation puts forward control measures from two aspects: "the coordinated development of the internal subsystem of urbanization" and "the coordinated development of urbanization among regions".The coordinated development of the internal subsystem of urbanization: deepening the reform of household registration system and land system,promoting the development of regional economic integration and expanding the opening pattern,controlling the destruction of ecological environment and strengthening coordinated governance,promoting the regional equalization of public resources allocation and public services,this dissertation puts forward optimization control measures for the development of internal subsystems of urbanization.In addition,it extends to the external environment of the government and the market,which has an effect on the internal subsystem of urbanization,and thinks that correctly dealing with the relationship between the government and the market is not only the requirement of deepening the reform of administrative system,the modernization of governance system and governance ability,but also the external guarantee of the coordinated development among the internal subsystems of urbanization in Beijing-Tianjin-Hebei region.The coordinated development of urbanization among regions: the evolution from the "dual core" of Beijing and Tianjin to the regional "multi-polarization" pattern,the transformation from "point-axis" development to "circle-level" development,the construction of network traffic system to ensure the efficient operation of urban agglomeration,taking the construction of Xiongan New area as an opportunity to focus on spatial optimization,this dissertation constructs the coordinated development pattern of urbanization in Beijing-Tianjin-Hebei region,in order to promote the scale effect of urban agglomeration. |
