The predominance of individual migration and a lack of coordination among government agencies result in a situation in which migration in the USSR often works at counter-purposes, with people moving away from areas suffering from a labor shortage and into areas with a labor surplus. A system of economic measures is advocated to optimize Soviet migration patterns. Since differences in living conditions are the basic motive between migration, an effort should be made to establish relationships between region al living standards that would attract migrants to regions with a labor shortage and induce them to settle permanently, instead of taking temporary advantage of high wage rates.  相似文献

A review of Soviet migration research finds that only a modest beginning has been made despite some useful results. Further progress in this area requires broader migration studies, beyond the manpower-oriented approach adopted thus far; wider use of mathematical techniques and improved research methods; improvements in the statistical data base on migration, and the coordination of Soviet migration research through the establishment of a central research center in this field.  相似文献

The purpose of this paper is to prove the existence of Hopf bifurcations in Sheppard's generalized dynamic migration model. Hopf bifurcations appear as a result of structure changes in the system. First, we deal with the general case of H cities. Then, the case of two cities is dealt with.  相似文献

This study analyses the future goals of population development in Shanghai from the viewpoint of population carrying capacity and ecological footprint. The population carrying capacity is one of the fundamental factors researchers and policy-makers need to take into account in managing and planning the development of a country or a region. This study focuses on the case of Shanghai, based on previous ecological footprint analysis, and builds a comprehensive index evaluation model. By applying basic principles of multi-goal decision-making analysis and operating methods of system dynamics, it calculates population carrying capacity corresponding to different standards that resource-economic factors can support. It further explores issues related to population change in the metropolis and relevant policy measures.  相似文献

抗战时期浙江省的人口迁移与地域分布   总被引:5,自引:0,他引:5  
抗战时期浙江省的人口迁移总数约有 5 0 0万人 ,其迁移情况极为复杂。其中 2 0 0余万人迁至省外 ,主要分布于闽、赣、皖、沪和华中、西南各省。大部分移民是在省内迁移。战时浙省移民迁移持续时间较短 ,最终转化为移民的只是少数。由于种种原因 ,战争期间即有部分移民回迁。战争结束后 ,绝大部分移民均回迁原住地。难民迁移的最根本最内在的动力来自经济和政治因素 ,尤其是经济因素  相似文献

转型期英国人口迁移以17世纪中叶为界先后形成了生计型迁移和改善型迁移两种模式。17世纪中叶以前,随着人口快速增长而出现乡村人口过剩,许多人为生计所迫,在原住地推力和城市拉力的双重作用下形成了生计型迁移模式。这一时期人口迁移具有相当的盲目性和不确定性。17世纪中叶以后,人口增长减速,经济地理布局日趋均衡,城市拉力作用减弱,人口迁移走向地方化和有序化,从而形成了改善型迁移模式。转型期英国人口迁移模式的变化深刻影响到向近代社会转型的历史进程。  相似文献

明清时期陕西境内的人口迁移   总被引:2,自引:1,他引:2  
时清时期是我国历史上人口迁移极其频繁的时代。本文主要探讨明清两代今陕西省境内的人口迁移过程,包括人口迁移的原因、形式、迁移数量、外来移民的地区分布等。在此基础上,本文还分析总结了外来移民对迁入地区的人口分布、经济开发、自然环境等方面的影响。本文认为,由于外来移民的大量迁入,明清时期陕南许多山区得到广泛开垦,耕地面积大为增加,土地开发利用程度超过历史上任何时期,客观上促进了各有关迁入区经济的发展。但由于大肆毁林开荒,盲目扩大耕地面积,致使陕南山区自然环境遭到严重破坏,自然灾害频频发生,从而制约当地经济的持续发展。这一教训我们应引以为诫。  相似文献

Commuting, Migration, and Rural-Urban Population Dynamics   总被引:5,自引:0,他引:5  
Over the past 25 years social scientists attempting to explain the dramatic changes in the relative distribution of urban and rural population growth have gravitated toward two competing explanations. The regional restructuring hypothesis holds that changes in the spatial distribution of employment opportunities have been dominant whereas the deconcentration hypothesis attributes these changes to changes in residential preferences of workers and consumers. We develop an empirical test of these two explanations based on whether commuting and migration are positively or negatively related after controlling for other economic factors. Our econometric results support the deconcentration hypothesis.  相似文献

The North Atlantic Population Project (NAPP) is a massive database of historical census microdata from European and North American countries. The backbone of the project is the unique collection of completely digitized censuses providing information on the entire enumerated populations of each country. In addition, for some countries, the NAPP includes sample data from surrounding census years. In this article, the authors provide a brief history of the project, describe their progress to data and plans for the future, and discuss some potential implications of this unique data resource for social and economic research.  相似文献

This article focuses on the development and evolution of migration and population redistribution modeling within the spatial context of multiregional demography. It begins in 1965, when the state-of-the-art consisted largely of ideas and techniques imported from other disciplines (regression analysis, gravity models, Markov chains, and matrix cohort-survival population projection models) and then continues on to tell the story of multiregional demography, its evolution and emergence as a fully developed paradigm for studying the spatial dynamics of migration and population redistribution and, more recently, its approach for estimating the necessary migration input measures from inadequate data.  相似文献

A simple hierarchical migration model is proposed as a mechanism for the redistribution of population within a Christaller central place hierarchy. Given a predefined functional hierarchy, the migration process causes any initial population distribution to converge to an equilibrium distribution. Under certain special conditions, the equilibrium is identical to a central place population distribution derived from economic base concepts.  相似文献

今天西北地区的民族构成及分布与民国时期各民族的人口迁徙流动有密切关系。灾荒、战乱匪祸及人为的经济、政治压迫等因素共同作用,造成该地区人口的非正常迁徙频繁发生,而且迁徙情势复杂多变,并最终对近代西北社会的发展产生了重大影响。  相似文献

The distinctive aspects of settlement of the Far Northern regions of the Soviet Union are reviewed with particular reference to the Aldan district, a gold and mica mining area in southern Yakutia. The main source of population has been net in-migration, with two-thirds of the labor force consisting of persons who move to the area temporarily, usually for one to three years. The permanent segment of the population represents only about one-third of the total. Working ages predominate among the migrants, and there has been traditionally a predominance of males, especially in the early stages of area development. However the sex ratio tends to become balanced as an area matures and the economy becomes more diversified. Indigneous ethnic groups represent only 9 percent of the Aldan population, with Russians predominating among the migrants and representing 78 percent of the population.  相似文献

美国特殊利益集团对全球霸权主义的追求、根深蒂固的反共主义,以及为维护世界资本主义的一统天下,决定了美国对苏联意识形态进攻的必然性。在苏联存在的几十年间,美国从未放弃消灭或西化苏联的图谋。在苏联基本坚持马克思主义的指导和社会主义道路的情况下,这种图谋难以实现。但是,当苏联把马克思主义教条化和僵化,并在西方和美国意识形态进攻面前逐步西化,就潜伏了巨大危险。一旦苏联领导彻底抛弃马克思主义意识形态,而以美国等西方国家宣扬的所谓全人类价值观作为指导时,苏联的解体和西化也就变得不可避免。  相似文献
