Adjustment of Administrative Divisions and Upgrading of Industrial Structure in Hefei Metropolitan Area:Taking"Partitions of Chaohu"as a Quasi-natural Experiment

Administrative regions are an important environment for the operation of China's market economy.The relevant economic subjects cannot predict the policy of adjustment of administrative divisions and carry out conscious migration behavior,adjustment of administrative divisions can be regarded as a quasi-natural experiment.The three cities of Hefei,Wuhu,and Ma'anshan,which are directly related to the adjustment of the administrative division of Chaohu,are taken as the treatment group,and the seven adjacent cities of Lu'an,Huainan,Chuzhou,Bengbu,Anqing,Chizhou,and Tongling are taken as the control group.Differences-in-Differences method and relevant control variables affecting the upgrading of industrial structure are used to test.The test results show that"Partitions of Chaohu"has a significant industrial structure upgrading effect by promoting the optimization of spatial layout,the cross-regional flow of production factors and the effective management of Chaohu Lake Basin.At the same time,the increase of total retail sales of consumer goods,urban fixed assets investment,public utility expenses in science,education,culture and health,and population plays a significant positive role in promoting the upgrading of industrial structure,while foreign direct investment plays a certain inhibition role in the upgrading of industrial structure.In order to meet the ever-developing space demands and enhance the impact on surrounding areas,the Hefei metropolitan area should be driven by technological innovation,strengthen the integration of industrial chains,improve the business environment and transportation network,and continuously promote the upgrading of industrial structure and the formation and development of new productive forces.

Evolutionary Pattern and Effect of Administrative Division Adjustment During Urbanization of China:Empirical Analysis on Multiple Scales

The adjustment of administrative divisions is one of the important factors guiding China's urbanization, which has profound economic and social effects for regional development. In this paper, we comprehensively describe the process of the adjustment of administrative divisions at provincial and municipal levels in China and summarize the effects on the basic structure and patterns of the spatial development. We quantitatively assess the effects on fields such as urbanization and social economy through the use of multidimensional scaling. The results show that: 1) Upgrading county to municipality(or city-governed district) is the main way of adjusting the administrative divisions. It is also an important factor in the spatial differentiation of interprovincial urbanization. China's population urbanization can be divided into four patterns including interprovincial migration, provincial migration, natural growth, and growth caused by the adjustment of administrative divisions, which is also the main reason for the increased Chinese urbanization rate at the provincial level. 2) Taking the city of Beijing as an example, we generalize five adjustment patterns made to administrative divisions: the set-up of sub-districts, the set-up of regional offices, the upgrading of townships to sub-districts, the upgrading of townships to towns, and the set-up of towns and the addition of new regional offices. We summarize the municipal urban spatial structure, including the sub-district office area in the central urban area, the regional office area in the new urban area, the mixed area of villages, towns, and sub-district offices in the suburb area, and the township area in the outer suburb area. 3) The adjustment of administrative divisions triggers a significant circulative accumulation effect, resulting in the spatial locking of population and industrial agglomeration. It affects the evolution of the urban spatial form and plays an important role in shaping the urban spatial structure to move to the characteristic of multicenter. In general, the adjustment of administrative divisions was an important factor affecting the inflated statistical level of urbanization and also an important driving force for the evolution of Chinese urban spatial organization structure.

Spheres of Urban Influence and Factors in Beijing-Tianjin-Hebei Metropolitan Region Based on Viewpoint of Administrative Division Adjustment

The coordinated development of Beijing, Tianjin and Hebei has been elevated as China's important strategy. And, the priority in considering how to bring the maximum effect of their coordinated development into play is to delineate the spheres of urban influence with regard to the cities in the Beijing-Tianjin-Hebei Metropolitan Region. By building an evaluation index system of urban comprehensive strength, this paper applies the principal component analysis method to determine centrality strength of the cities, and the breakpoint theory and weighted Voronoi diagram to identify the spheres of urban influence in all central cities of the region. Results show that 13 central cities within the region greatly differ in strength, which can be classified into four tiers and that the spheres of urban influence do not have a high goodness of fit with administrative jurisdiction scope. Cities like Beijing, Tianjin, Shijiazhuang and Handan have larger spheres of urban, spheres of urban influence in Tangshan and Qinhuangdao are basically consistent with their administrative jurisdiction scopes, and seven cities including Langfang and Baoding have smaller spheres of urban influence. So according to these cities' comprehensive strength and spheres of influence, the region can be divided into five plates: Beijing, Tianjin, Shijiazhuang, Tangshan and Handan. The major influence factors for inconsistency between spheres of urban influence and spheres of jurisdiction include difference in urban administrative ranking, small number of central cities with weak strength, discrepancy in the number of counties under jurisdiction, unreasonable spheres of jurisdiction and diversity in topographical conditions. In order to solve the imbalance in the spheres of urban influence and those of jurisdiction and better facilitate the coordinated development of the region, it is advised to adjust administrative areas so as to obtain more optimized urban spatial layout and more reasonable urban scale hierarchy system.

Quantitative measurement of the effects of administrative division adjustments on regional development

Administrative divisions are the important foundation of national governance and social development,and the adjustment of administrative divisions is a critical way to promote regional coordinated development.Under the background of globalization and regionalization,timely adjustment of administrative divisions is a major step to reconstruct the regional development pattern.In the perspective of regional coordinated development,this paper constructs an Administrative Rank Potential Energy(ARPE)model to explore the mechanisms of administrative division adjustment(ADA)under coordinated regional development based on the theory of regional interaction,spatial field energy model and power exponential function.The results show that:(1)The development potential and influence of an administrative region are closely related to the administrative jurisdiction,administrative resources,and the potential of regional coordinated development.(2)The growth rate of ARPE in the study area from 2010 to 2015 was 20.7% compared to the period 2005 to 2010,and the potential for coordinated development increased to 3.05% from 0.21% before the"cancelling"the prefecture-level city of Chaohu.(3)The measurement results of the usefulness of ADA can not only distinguish the complex impacts brought about by social development,but also accord with real social and economic development conditions.The ARPE focuses on the both regional integrated development and individual development,thereby serving as a reference for explaining and evaluating adjustments to administrative divisions at the macro-and micro-scales.

Administrative Division Adjustment and Housing Price Comovement:Evidence from City-County Mergers in China

Interregional housing price comovement is a stylized fact worldwide.This study explores how it is affected by administrative division adjustment.We exploit city-county mergers in China as a quasi-natural experiment to construct a difference-in-differences strategy for causal identification.Based on monthly housing price data for districts(counties)in China from 2010 to 2019,we find that city-county mergers significantly improve correlations in housing prices between the merged county and the urban district.This effect is more obvious in cities with a large economic gap between merged counties and urban districts,located in the central and western regions,and with lower administrative hierarchies(non-provincial-capital cities).The mechanism test shows that the impact of city-county mergers on housing price comovement results mainly from integrating housing demand rather than integrating housing supply,like the unified land supply policy that local government implements in the new administrative scope after mergers.The results are helpful in understanding housing price comovement from the view of regional integration and provide clear policy implications for housing market regulation in China.

Space-time Relationship Between Urban Municipal District Adjustment and Built-up Area Expansion in China

Municipal district adjustment and built-up area expansion are two main forms of urban spatial expansion. Using geometric methods, this study constructed a space-time path method to characterize the space-time relationship between municipal district adjustment and built-up area expansion, and drew the space-time path sets of major prefecture level cities from 2000 to 2010 by constructing a coordinate system of the standardized built-up areas and municipal district areas. This divided them into four quadrants, namely, H-H, L-H, L-L, and H-L, based on the relative mean value to evaluate overall and individual stability by three indexes of the trajectory vectors, namely, direction, length, and slope. Results provide the following conclusions. 1) Municipal district adjustment is an effective spatial expansion way for city-scale promotion in China. Since 2000, municipal district adjustments have been mainly distributed in the eastern coastal regions and mid-western capital cities along with their surrounding cities. 2) Municipal district adjustment affects the scale and status of a city in China. Many cities that have expanded municipal districts behave stably and cross quadrants. 3) Great majority second-tier cities have effectively promoted their scale and status through municipal district adjustment. The municipal district adjustment of medium and small cities in the mid-west area is relatively advanced compared with city development. 4) Municipal district adjustment with minimal magnitude is severely restricted from upgrading the scale and status of a city. The transformation from entirely incorporated counties or cities to municipal districts should be the mainstream in future municipal district adjustment.

Administrative division adjustments and stock price comovement:Evidence from the city–county mergers in China

Under the background of Chinese market segmentation,whether governmentled administrative division adjustments can promote regional economic integration is a practical issue.Taking interregional firms’stock price comovement as a micro measurement of regional integration,this paper investigates the regional integration effect of administrative division adjustments,i.e.,city–county mergers.We find that stock price comovement between county-level and municipal district-level firms in the merged counties and municipal districts significantly improve after city–county mergers,particularly in regions with a higher degree of market segmentation and lower degree of marketization.We further find that the increase in stock price comovement caused by city–county mergers emerges from the increase in comovement of real activities between firms in the merged counties and municipal districts.Taken together,our results suggest that government-led administrative division adjustments effectively promote regional integration.

Stages and Characteristics of Metropolitan Administrative Division Adjustment in China Since 1997

Administrative division adjustments(hereinafter referred to as ADA) proceed throughout China's rapid urbanization, especially during the process of metropolitanization. It has become an integral part of the transformation of China's urban and regional governance. Based on an analysis of ADA cases at the metropolitan level since 1997, this paper suggests that the stages and characteristics of ADA in China are closely related to the metropolitanization process. The internal dynamics and external constraints jointly created two stages of ADA at the metropolitan level in China, namely, a first stage from 1997 to 2007 and a second stage from 2008 to now. In the first stage, ADA primarily aimed at turning counties into districts, to meet the metropolis' demands for expansion. In the second stage, local governments laid equal stress on the two approaches of ADA, i.e., turning counties into districts and district restructuring. Such a change corresponded to the diversification of development demands of the metropolitan area. The evolution of ADA from the first stage to the second not only reflects the changing characteristics of metropolitanization at different times, but also demonstrates the viability of ADA as a means to improve the governance structure of the metropolitan area. ADA at the metropolitan level in China since 1997 basically accommodates the development of space and governance in the metropolitan area, which promotes the rapid development of a large metropolitan area.

“强省会”战略的产业升级效应——基于省会城市行政区划调整的准自然实验

“强省会”战略是提高省会城市综合竞争力的重要抓手,而产业结构是衡量一个城市综合竞争力的核心指标。基于2003—2020年中国26个省会城市的面板数据,依托省会城市行政区划调整的准自然实验,运用双重差分模型科学评估“强省会”战略的产业升级效应。研究结果表明,行政区划调整显著促进了省会城市产业升级,但这种促进效应只能持续3 a。机制检验显示,行政区划调整将通过缓解资源约束瓶颈和提高技术创新水平2种渠道带动省会城市产业升级。进一步分析发现,相较于行政区合并而言,撤县设区对省会城市产业升级的促进作用更强;相对于副省级省会城市和多中心空间布局模式下的省会城市而言,普通省会城市和单中心空间布局模式下的省会城市在行政区划调整后获得更大的产业升级效应。

全过程视域下的撤县(市)设区府际博弈与调适——基于Z市S区行政区划调整30年的纵向追踪

撤县(市)设区不是一蹴而就的,伴随其间的府际博弈,深刻影响着调整的进程与成效。虽然已有研究比较丰富,但主要集中于事前的动因分析或事后的绩效评估,尚未有研究系统归纳贯穿撤县(市)设区不同阶段的府际博弈逻辑及其深刻影响。基于已有研究和经验事实,以历史追踪而非点状的视角观察撤县(市)设区进程,从组织逻辑下居于主导地位的上级权威、激励逻辑下事实存在的下级弱自主性、目标逻辑下必须兼顾的稳定与发展三个层面,构建了一个理解撤县(市)设区府际博弈与调适的分析框架。在此基础上,通过对Z市S区30年相关行政区划调整过程的纵向追踪,发现各级政府遵循不同的博弈逻辑进行策略选择,进而形成了不同程度上的服从、合作甚至对抗模式,深刻影响着区域融合发展进程,也间接表明撤县(市)设区并不能直接推动新设区与主城区的融合发展。上述工作不仅初步打开了贯穿撤县(市)设区全过程的府际博弈“黑箱”,也拓展了基于过程视角的府际关系研究的适用场景与解释限度。

行政区划调整与城市空间结构演化——基于撤县设区的视角

在新型城镇化建设对城市紧凑集约发展提出更高要求的背景下,探讨行政区划调整对城市空间结构的影响具有重要意义。基于2000—2016年全国范围内演进的撤县设区数据,深入考察了撤县设区带来的城市空间结构演化效应的研究发现:(1)撤县设区促使了城市空间形态松散化和内部低密度发展,该结论在考虑多种指标、方法以及政策滞后效应之后仍成立。(2)撤县设区政策对东部城市的空间结构松散化影响更强,且不利于其发挥中心集聚优势;相比于建设规制较弱的城市,规制较强的城市受到撤县设区对城市空间结构分散化的影响更为显著。(3)进一步研究表明,自主选择型撤县设区对城市空间结构分散化的影响更加明显,而顺应融入型撤县设区则会在一定程度上促进城市空间结构趋于紧凑化。

基于易经地理思想的国家空间治理结构顶层设计

以国土空间治理能力现代化助推高质量发展,是保障中华民族伟大复兴、推进中国式现代化的必然要求。本文在继承和发展易经地理思想的基础上,构建了“太极空间治理结构模型”,确定山海关为“东亚太极点”。中国国家空间治理结构的顶层设计,应围绕“山海关”而层层展开。在中央核心区,按照“东亚陆海中心+陆地屏障+海洋屏障”的环首都治理结构,将北京扩容至山海关,河北省扩容至大兴安岭中央主峰,天津直辖市扩容至渤海海峡。在四方支撑区,各布局1个直辖市(上海、重庆、天骄、威虎),并增设云北省,扼控各方向的关键节点。在外围屏障区,增设澎湖、昆仑2大直辖市和楼兰、北庭2大特别行政区,形成最有利于中国长治久安的边疆治理结构。

尺度结构化视角下城市行政空间重构研究——基于安徽省芜湖市的实证分析

基于尺度结构化的理论视角,以安徽省芜湖市2000年以来的行政空间重构历程为实证研究对象,深入探讨多样化的城市行政空间重构策略对于中国国家权力尺度体系的塑造及其背后的权力运作机制。研究发现:1)中国城市行政空间重构中尺度关系的变化既包含国家权力在纵横坐标系中的流转、分化与融合,也涉及国家对于社会组织自治权的吸收。经此所塑造的国家权力的尺度体系不再局限于传统的“层级式”结构特征,而是呈现为叠加了各类尺度“子集”和“准尺度”的“马赛克”形态。2)这一系列尺度关系的变化是由各级各类政府机构、基层自治组织、居民等不同行动主体间的竞争所推动,核心利益在于领域生产的经济价值,而竞争的形式及其结果一方面取决于以服从、制衡、调停为特征的既有权力关系的不对称性和平衡机制,另一方面也催生了以社会自治组织与基层政府间联盟为例的新的权力秩序。

明代贵州行政区划调整困境及其应对策略

明朝廷通过“犬牙交错”和“交叉叠合”的行政区划设置迅速稳定新设贵州省局势的同时,也给当地后续管理带来了诸多不便。为理顺当时复杂的管理关系,逐步推动地方改土归流,明代贵州部分官员主张调整不合理的行政区划设置。但行政区划调整涉及各方面的利益分配,对行政区划调整会引发动乱而产生的顾忌及邻省官员和当地土司预期该调整会造成自身利益损害而进行的阻挠,就成了贵州行政区划调整的最大阻碍。为此,只能通过循序渐进和因势利导的方式,逐渐调整省内部分问题突出的行政区划设置。尽管这些问题无法彻底解决,但官员的努力为当地社会发展以及地方制度完善提供了重要保障。

地籍区与地籍子区更新原则与方法步骤浅析

随着城乡规模的发展、行政区划调整以及数学基础的更新,基于第二次土地调查确权登记成果的地籍区、地籍子区已经无法满足现阶段地籍管理工作的需要,亟待对其进行调整和更新。本文以昆山市农村集体土地所有权确权登记成果更新为例,在原有地籍区划界线基础上,结合第三次国土调查行政区划界线、高分辨率影像、城市规划数据等资料分析了地籍区、地籍子区的更新原则和方法步骤,以便更新成果能够更好地满足新形势下自然资源规范化管理的需要。

行政区划调整视角下的区域发展新途径--以重庆市为例

在新形势下,通过以城市群为主导、推动产业升级、加强基础设施建设等措施,重庆市正在积极打造内陆开放高地和国家中心城市,带动周边地区蓬勃发展。然而,面临的挑战包括区域协调难度大、产业结构调整困难、高成本的基础设施建设以及生态环境问题。为应对这些问题,政府可以采取以下措施:一是制定科学合理的区域发展规划。二是加强政策支持和引导。三是建立多元化的投资机制。四是强化生态环境保护意识。通过采取这些优化措施,为重庆市和其他调整了行政区划的地区找到可持续和协调发展的路径,实现经济高质量发展和生态环境保护的双赢。

大城经界:中国超特大城市的行政区划调整之路——一个“行政区划调整链”的视角

行政区划是超特大城市发展与治理的重要政策工具,然而已有研究较少针对我国超特大城市行政区划的设置与演变开展系统分析,对于不同行政区划调整方式之间的逻辑关联也缺乏充分关注。在系统回顾我国超特大城市行政区划调整历程的基础上,研究认为我国超特大城市的行政区划调整总体呈现出鲜明的规律性,普遍经历了由区界重组到市领导县、由市领导县到撤县设区、再由撤县设区到区界重组的三个典型阶段,各阶段的行政区划调整方式之间并非相互独立,而是构成了一个前后紧密关联的行政区划调整链,其背后体现了由城乡分治到城乡合治、由权力分立到权力统合、由外部扩张到内部精细化治理的逻辑。研究有助于丰富对我国超特大城市行政区划调整实践的认识及其运行逻辑的理解,也有助于为我国超特大城市未来行政区划的进一步调整优化提供参考。

城市管治、区划调整与空间整合——以常州市区为例

以常州市区为例,重点从产业空间管治的角度,分析了在行政区划调整下城市管治重构与空间整合。通过分析现状开发区在主导产业选择、产业空间布局与区位选址方面的问题,论文认为,当前制度框架、经济政策与要素集聚、社会文化及空间规划等方面是造成目前中心城区之间管治冲突的主要原因;行政区划调整虽然有利于城市规模的做大和某种程度上规避强大的县级市与中心城市之间的日益突出的矛盾,但当前的发展并没有有效地削减这两大空间单元之间的本质冲突。进而,论文又从制度重构、政策导向与空间整合三方面重点分析了要构建有效的市区管治模式、实现空间协调发展与整合。

近十年来中国城市行政区划格局的变动与影响

近十年来,中国行政区划基本格局出现了以地级建制城市与市辖区数量进一步增多、并伴随着基层乡镇规模整合导致乡镇数量减少的发展特征。其影响在于进一步促进了中国城市化进程的发展,消除了大城市、特大城市规模扩张进程中的体制性障碍,为降低城市行政运行成本提供了新的体制保障条件。城市发展过程中的历史包袱,城市权益管治空间架构的传统惯性,各种相关利益盘根错节,使得城市地区行政区划调整所面临的任务将进一步加重。超前研究,统筹谋划,警惕利用行政区划调整机制来借机扩充政府班子、增设行政管辖机构的行为倾向,是行政区划要关注的主要命题。

从撤县设区到区界重组——我国区县级行政区划调整的新趋势

我国的城市化发展与城市行政区划调整密切相关。目前涉及到城市及城市地区的行政区划调整以区县级行政区划调整为主,主要包括"撤县(市)设区"、"区县合并"和"区界重组"这三种类型。本文通过对1983年以来所有撤县(市)设区和区县合并案例的发生特征进行统计分析,认为2000年以前我国的城市化发展表现出广泛的城市数量扩张与重点城市规模扩张并举的特点;2000年以后则表现为建立在经济发展基础之上的城市大规模扩张。继而本文总结了近几年来区界重组的发生情况,认为随着我国城市化发展从城市规模扩张进入到城市功能与内涵提升的新阶段,区界重组正在取代撤县(市)设区和区县合并,成为我国区县级行政区划调整的新趋势。
