Planning and construction of Xiong’an New Area(city of over 5 million people):Contributions of China’s geologists and urban geology

China established Xiong’an New Area in Hebei Province in 2017,which is planned to accommodate about 5 million people,aiming to relieve Beijing City of the functions non-essential to its role as China’s capital and to expedite the coordinated development of the Beijing-Tianjin-Hebei region.From 2017 to 2021,the China Geological Survey(CGS)took the lead in multi-factor urban geological surveys involving space,resources,environments,and disasters according to the general requirements of“global vision,international standards,distinctive Chinese features,and future-oriented goals”in Xiong’an New Area,identifying the engineering geologic conditions and geologic environmental challenges of this area.The achievements also include a 3D engineering geological structure model for the whole area,along with“one city proper and five clusters”,insights into the ecology and the background endowment of natural resources like land,geothermal resources,groundwater,and wetland of the area before engineering construction,a comprehensive monitoring network of resources and environments in the area,and the“Transparent Xiong’an”geological information platform that is open,shared,dynamically updated,and three-dimensionally visualized.China’s geologists and urban geology have played a significant role in the urban planning and construction of Xiong’an New Area,providing whole-process geological solutions for urban planning,construction,operation and management.The future urban construction of Xiong’an New Area will necessitate the theoretical and technical support of earth system science(ESS)from various aspects,and the purpose is to enhance the resilience of the new type of city and to provide support for the green,low-carbon,and sustainable development of this area.

GROWTH OF NEW DESIGNATED CITIES IN CHINA

The opening of the economy has contributed to the rapid urban development in China over the last 17 years from 1979 to 1996. It is worthwhile to note three new development trends of Chinese urban system. The first trend identifies the emergence of mega urbanization regions. The second trend rebuilds a closer tie between the Chinese urban system and the global urban system through the development of the world (global) cities and international cities. The third trend shows the fast polarized development in hinterlands and peripheries around advanced economic regions. However, the research literature on Chinese urbanization in English has shown the scarcity of good databanks and the analysis results are incomplete. Some researchers also always question the quality of the data. Using the most completed and most recent data, this paper reviews the growth of China's new designated cities since 1949. This paper also seeks to examine the various policies and to explore the underlying factors that have affected the growth of China new cities. From the development of China's cities in the past 47 years from 1949 to 1996, it is easy to find that metropolitan cities developed with a relatively high rate compared with smaller ones, but the ratio of number and population to whole country cities remained stable; Chinese urban system development had entered a phase of small cities development; in terms of cities regional distribution, the south and east region is still the central area of urban development.

中国消费中心建设:现有格局、调整逻辑与发展路径

在制造业大国、生产中心背景下,我国又提出经济的消费转型,要建设消费大国,打造(国际)消费中心(城市)。当前,我国一些传统消费型城市经历了历史嬗变,后发的消费型城市更多立足于生产制造,一些偏远、基层城镇逐渐向消费中心转型,但大多数消费中心还未能实现专门性独立发展。从生产中心到消费中心有着很深的内在调整逻辑,包括经济增长动力改变,由供给推动向需求拉动转型;社会主要矛盾改变,更多化解发展不平衡不充分矛盾;经济水平提高,消费大发展的条件已经具备;资源和环境面临危机,需要以消费经济化解生产经济紧约束;国内外环境改变,消费中心担负经济突围重任。我国消费中心建设还存在诸多制约因素,如收入分配不合理,区域消费制约严重;过多生产作业加班,挤占生活消费空间;城市拥挤,消费流动不畅;公共设施落后,不能支撑消费大场景;更重生产,消费经济功能发挥有限;片面追求物质财富的拥有,全民生活消费筹划建设不够;内卷化竞争过于激烈,消费激情难以焕发;过多追名逐利,消费价值观有待重建。需要进行相关体制机制建设,政策调整方向包括适应生产劳动人工时间减少的趋势,增加消费时间;调整城市布局,畅通消费流;强化公共消费设施建设,营造消费大场景;调整收入分配,构建外向型消费结构;深化规律性认识,发挥好后工业时代消费对经济的主功能作用;引导消费,积极筹划消费蓝图;防范内卷化竞争,焕发全民消费激情;全面发展,重构生产价值和消费价值观体系。

中国式城镇化:从传统城市化向新型城镇化转型的理论探索与实践创新

城市是人类文明的载体。人类文明经历了农业文明时代,进入到工业文明时代,开启了城市化进程。中国的城市化相比西方发达国家的城市化起步晚,因此在中国城市化前期无论是在理论上还是在实践上都是西方发达国家的跟随者和模仿者,以“物”为主的城市化成为发展的方向,因而也出现了若干城市病。新中国是中国共产党领导的国家,以人民群众的利益为根本遵循。因而,跟随西方传统城市化的发展,不符合中国共产党所提出的“人民城市人民建、人民城市为人民”的初心,也不符合中国的国情和发展规律。中国特色社会主义进入新时代,以习近平同志为核心的党中央果断选择了以人为本的新型城镇化道路,并以新型城镇化为抓手和新路径,扭转了中国城市化的发展方向,有力地推动了中国式现代化建设与中华民族现代文明的构建。中国从传统城市化向新型城镇化转型有其历史逻辑,也是“两个结合”的中国化与当代化表达。
