江苏省城镇化发展协调度评价与地区差异分析

将城镇化分解成人口城镇化、经济城镇化、土地城镇化和社会城镇化4部分,且认为这4部分应处在协调耦合状态,用TOPSIS法对江苏省城镇化发展协调度进行评价,之后对评价结果的地区差异进行分析,以对城镇发展政策制定提供依据。研究表明:常州和扬州在优质协调区;南京、镇江、苏州和无锡在良好协调区,且土地城镇化相对滞后,说明城镇土地高效集约利用;徐州、淮安和南通在基本协调区,徐州与淮安土地城镇化过快,社会城镇化滞后,表明城镇土地粗放低效利用,同时忽视公共服务产品供给,南通土地城镇化滞后,表明城镇扩张缓慢,城镇化的土地代价水平较低;泰州和盐城在轻度失调区,盐城经济城镇化滞后,泰州土地城镇化滞后,土地集约利用强度大,城镇发展选择的是一种精明增长路径;连云港和宿迁在中度失调区,土地城镇化明显快于其它城镇化,城镇发展土地代价水平高,具有相当过渡性损失。     

中国城市化水平的综合判断

在测度和评价城市化水平高低时应该对人口城市化水平和城市人口绝对规模进行综合判断。学界通常用市区非农业人口口径来计算城市化水平,对城市外来人口考虑不够。对这种偏小的口径进行修正后发现中国的城市化水平至多略低于同等收入下的国际城市化水平。从城市人口与城市经济的适应程度看,中国的城市劳动生产率与发展状况类似的国家相比有偏低的倾向。因此,与流行的看法相反,中国的城市化水平与经济发展相适应的。笔者认为中国城市的存量部分已经"人满为患",未来城市化的着力点应是城市的增量部分,包括现有城市规模的扩大和新城市的设置。应进行户籍制度、土地制度、创业制度等制度创新,为城市发展提供宽松的外部环境。     

TYPES OF URBANIZATION IN THE USSR

A typology of urbanization is developed for the 163 major civil divisions of the USSR on the basis of three factors: (a) an index of the level of urbanization (incorporating the percentage of urban population, the share of cities of 100,000 or more in urban population, an index of urban agglomerations, and a coefficient adjusting for the density of urban population); (b) the structural complexity of urbanization (which is treated as deriving either solely from the urban population percentage in the simplest case; or from the urban population percentage and the share of large cities in a two-element case, or additionally from the presence of urban agglomerations in the three-element case); (c) the dominance of any of the three structural elements. The typology yields 24 combinations of the three factors out of a theoretically possible total of 54 combinations, some combinations being represented only by one or two examples. The typology is conceptualized as a mobile system in which particular major civil divisions may advance to higher levels as urbanization processes continue.     

CONTEMPORARY URBANIZATION AND AN OPTIMAL SIZE FOR SOVIET CITIES

Three Leningrad geographers use a recent book by Yu. L. Pivovarov of Moscow as a point of departure to focus on two issues relating to urbanization in the Soviet Union: (1) the nature of the urbanization process; (2) optimal city size. The authors challenge Pivovarov's view that urbanization is a relatively independent socio-historical process in which places evolve on their own from lower forms to higher forms of settlement. They contend that urbanization is closely related to the characteristics of a given socio-economic system and that, in the Soviet Union, it involves not only city growth per se, but the relationship between urban and rural settlement and the penetration of urban life styles into the countryside. On the controversy surrounding optimal size, the writers say that the issue is not to find the ideal size for cities in general, but to set desirable limits for cities of different functional types and, most important, to insure that the infrastructure of cities keeps pace with industrial potential. If industrial development moves far ahead of infrastructure, the authors argue, it is desirable to constrain further growth, especially by keeping out industries that tend to have an agglomerative effect in attracting other industries. Once infrastructure catches up with industrial development, the constraints can be eased and the economies of size inherent in large cities can again come into play.     

Quantitative Regularities in the Urbanization of the USSR

Simple arithmetical formulas are proposed for the study and analysis of urbanization processes. The formulas establish functional relationships between the urbanization level at the beginning of a particular study period, the changes in urban and rural population during the period, and the urbanization level at the end of the period. The relative share of administrative centers and of other urban places in a particular major civil division in total urban population is also considered. Different types of urbanization processes are discussed and plotted on a graphic-analytical model (nomogram). Contrary to general assumption, it is found that in the USSR it is not the very large cities (500,000 and over) that are increasingly concentrating urban population, but the next lowest size class (100,000–500,000). Further research into urbanization processes in particular spatial settlement systems is urged.     

改革开放以来中国城市化与经济社会发展关系研究

中国自改革开放以来,工业化实际上在走城乡二元发展的道路,城市化与工业化相伴生。消费需求的三次升级,一方面刺激了经济增长,使城市化的生活方式在城市和广大农村地区快速扩展,另一方面,也吸引了外资和技术的引进。浙江的民营企业加专业市场是中国自下而上城镇化的典范,江苏的集体经济加开发区建设是政府主导城市化发展的一种模式。本文重点探讨中国改革开放25年来城市化的主要动力机制变化及其对经济社会发展的影响,并进行浙江、江苏城市化实证分析。

新时期新疆边境城镇体系构建和口岸小城镇发展

新疆所处区位条件决定了边境的稳定与发展在整个区域经济中占据重要位置。把城市化和对外开放结合起来,通过边境城镇体系的构建来密切边境城镇与腹地的联系具有积极作用。边境城镇体系通过交通轴线的连接,对不同层次、不同职能分工的核心、节点、边境城市和口岸小城镇进行空间纵深配置,从而发挥对外开放的城镇整体优势。口岸型小城镇是边境城镇体系的前沿,最具特色。在发展条件较好,规模较大的口岸可考虑直接设立建制镇。在一些自身设镇条件不足的口岸,可考虑与地方、兵团联合设镇,协调管理。     

CITIES AND DEVELOPMENT

ABSTRACT This paper starts with a “primer” on what we know about the conceptual and empirical links between development and urbanization. While historical experience of developed countries is reviewed, today's rapid urbanization in developing countries offers an intense set of challenges. Rapid urbanization requires massive population movements and enormous local and inter‐city infrastructure investments in a modern context of heavy government interventions in economies. This context raises under‐researched issues, discussed in the second part of the paper. First concerns the spatial form of development. How much development should be focused in mega‐cities, or huge urban clusters, as opposed to being more spatially dispersed, a critical question facing China and India today? How do we conceptualize and measure both the benefits and costs of increased urban concentration; and how are they linked to a country's evolving national industrial composition? Second, what is the evolution of spatial income inequality under massive rural‐urban migration? Is inequality heightened today relative to the past by national government policies which “favor” certain cities and regions and by local government policies in those cities that may try to deflect migrants by offering them poor living conditions?     

Urbanization and mortality decline

We investigate the relationship between mortality decline and urbanization, which has hitherto been proposed by demographers but has yet to be tested rigorously in a global context. Using cross‐national panel data, we find evidence of a robust negative correlation between crude death rates and urbanization. The use of instrumental variables suggest that this relationship is causal, while historical data from the early 20th century suggest that this relationship holds in earlier periods as well. Finally, we find robust evidence that mortality decline is correlated with urbanization through the creation of new cities rather than promoting urban growth in already‐extant cities.     

Urbanization Processes in North Vietnam

The pattern of urbanization of North Vietnam is traced from 1945 through 1960 to 1970. The average contribution of the in-migration component to urban growth was 40 percent from 1945 to 1965, but a slight net out-migration from cities marked the period of American bombings of North Vietnam after 1965. As a result urban population declined from 1.9 million in 1965 to 1.84 million in 1970, while total population of North Vietnam rose from 17.5 to 20 million. Urban growth has been distinguished by rapid rates of growth in large cities, low rates in middle-size cities, and no growth or even decline of population in the small urban places.

环南海国家及地区人口城市化特征与空间格局演变

环南海国家及地区既是海上丝绸之路建设发展的重要地带枢纽,也是进行国际合作的重要平台,由于区域内自然条件、社会经济基础和城市发展阶段等存在不同,其内部城市化过程与城市体系格局存在较大差异。本文基于1960—2020年环南海地区国家和主要城市层面等多尺度的人口数据,利用城市首位度指数与城市空间基尼系数两个指标,结合核密度等空间分析方法,对环南海国家及地区的人口城市化与空间格局的时空演化特征进行实证研究。研究表明：第一,环南海国家及地区大部分进入城市化发展后期,但区域内部城市化发展出现较大差异,越南、柬埔寨的城市化落后于其他国家（地区）;第二,区域内城市体系空间结构以强单中心结构为主,双（多）中心结构的国家及地区较少,城市体系内部发展不平衡,城市规模分布以首位分布居多;第三,主要城市人口空间集聚现象显著,且还有进一步集聚发展的倾向。本研究揭示了环南海国家及地区的城市发展过程和分布规律,对推进“21世纪海上丝绸之路”南海航线建设和中国—东盟自由贸易区建设具有重要的科学意义。     

江苏省城市化质量的区域差异时空分析

根据城市化的内涵及推进城市化的目的,从人口城市化、经济城市化、居民生活城市化、景观环境城市化和基础设施城市化等五个方面,构建区域城市化质量的综合评价指标体系,运用熵值法,对2001-2009年江苏县市城市化质量进行综合测度,并以此为变量,运用差异系数,对江苏县市城市化质量差异的演变过程与空间格局进行定量分析。结果发现:2001-2009年江苏区域城市化质量差异总体扩大的基础上呈现先扩大后缩小趋势,且主要表现为经济发展质量差异、基础设施质量差异和居民生活质量差异,人口发展质量差异和景观环境质量差异则相对较小;在空间上,县市城市化质量提升有向环太湖地区不断极化的态势。其中,地级市区以向下收敛为主;苏中和苏北县域以向上收敛为主,而沿海地区县域以向下发散为主;苏南地区的沿江县域以向下收敛为主,环太湖县域则以向上发散为主。     

The specifics and spatial structure of circular migration in Russia

Abstract

This article aims at distinguishing recurrent population movements within the territory of the Russian Federation between urban localities of different sizes and rural areas in connection to the processes of urbanization, suburbanization, and de-urbanization. Incomplete urbanization and the strong polarization of socio-economic space in Russia have resulted in two powerful contradictory population flows: centrifugal seasonal sub- and de-urbanization and centripetal labor migration from rural and small towns to large urban centers. The article discusses three forms of recurrent population mobility in Russia: (1) daily commuting of urban and rural inhabitants within metropolitan areas; (2) commuting to large cities and their suburbs for long-term employment intervals (weekly, monthly, etc.), (3) second-home commuting to countryside dachas. Unfinished urbanization in Russia not only attracts rural and small towns’ population to major cities but also keeps it within the latter. It slows down the real de-urbanization and induces specific dachas (second-home) suburbanization/de-urbanization, with these processes being closely interrelated. An opportunity to earn money in cities together with the impossibility of moving to major centers due to expensive housing encourages households to remain in small towns and rural areas. Meanwhile, inhabited rural localities (even ones distant from cities) attract seasonal population (dachniks).     

Information for Authors, 2001

The paper assesses the urban base for rapid economic development and urbanization projected for western China under the most recent central government policy of "grand development of the western region." It focuses on the socioeconomic characteristics, receptiveness to innovation, and linkages of western China's cities to the world, by utilizing data from government documents and census publications. The analysis reveals remarkable differences among the main urban nodes, raising questions about existing urban and regional development theory and practice in China.
