"This paper attempts to employ substantial source materials to shed light on the characteristics of population migration in a centrally planned society that is in the process of transforming to a market economy. In order to compare rural-urban migration in China with that in other developing countries, the data on 1985-1990 interprovincial population migration have been analysed. Some demographic research techniques on population migration, such as the impact on the place of origin and the place of destination, have been employed to assess the influence of rural-urban migration on China's long-term economic development. Economic betterment appears to be the sole motivation of rural population migration in China." 相似文献

"Patterns of and trends in demographic development in the Indian state of Uttar Pradesh have been analysed in this paper. Indices of urbanisation, literacy and occupational structure were used for this purpose. Their aggregate index represented the level of demographic development." The data are for 242 subdivisions of Uttar Pradesh for the census years 1971 and 1981. Particular attention is given to regional differentials in demographic indicators. The relationships among economic development and the measurements of literacy, urbanization, and occupational status are explored 相似文献

Groundwater depletion and pollution from small-scale tanneries have occurred in a marginally productive area in North Arcot district of Tamil Nadu. The magnitude of the problem is increasing due to the interactive effects of urban and population growth, increased groundwater extraction, depletion of forest cover and increase in the number of tanneries. When ecosystems are under severe stress common property resources quickly become degraded, and unless comprehensive measures are adopted, the ecosystem yields to stress and becomes irreversibly degraded. Policy interventions needed are identified based on existing gaps in the present system. 相似文献

"The paper brings out the role of political economy in influencing the process of urbanisation and [the] structure of settlement network. This is demonstrated through an empirical study of Hungary during the twentieth century. Three phases get easily distinguished: pre-1949 or the period of changes in the state boundaries; 1949-89 or the period of state socialism; and post-1989 or the period of institutional reform. An interesting finding is that there was a bias in favour of large cities and county seats in allocation of development funds under all the regimes." 相似文献

Development zones in China are planned as self-contained communities in order to achieve a locally balanced distribution of jobs and homes. Yet the plans are often defied by the market, leading to jobs-housing imbalance as an undesired consequence. In this paper, we examine the case of Suzhou Industry Park (SIP) to explore what has actually happened within a Chinese development zone. Our study reveals the de facto qualitative jobs-housing imbalance within SIP notwithstanding the de jure quantitative balance as envisaged in the local land-use plan. This finding explains why most workers within SIP have to search for homes far away from their workplaces. The qualitative imbalance is attributable to a series of interrelated factors, including (a) the oversupply of industrial land vis-à-vis the undersupply of land for public facilities and residential amenities, (b) the unaffordable house price for local workers, and (c) the increased use of automobiles by commuters. On top of its policy implications, this paper also reflects on the fundamental relationship between planning and market as a broader intellectual perspective to study urban China’s mobility, housing and social issues. 相似文献

An analysis of internal migration in two regions, or dukuh, of Yogyakarta Special Region, Indonesia, is presented. Three types of migration are identified, commuting, circular migration, and out-migration. The focus of the study is on the increase in commuting and circular migration that has occurred since the 1970s; its relationships with education, agricultural innovation, and improved transportation; and the importance of circular migration as a link between rural and urban areas. 相似文献

This study examines the issue of labour needs and supply for six small-scale irrigation projects located in Anambra State, Nigeria. The data were derived from a random sampling survey of participating farmers during a six-month period in 1981. The sample population of the farmers was 323 (approximately 13 per cent of the total population of 2549). The study found that many farmers found it necessary to hire labour in order to cope and that this labour was very costly. This suggests that even in a densely populated rural area of Nigeria, labour availability should not be taken for granted. 相似文献

针对当前国内研究区域城乡统筹水平定量测评方法中存在的问题,如未能区分整体发展指标和协调发展指标,截面和时序数据难以同时体现,以及城乡统筹评价指标体系集成数据导致的“黑箱子”效应等问题,本文建立了涵盖城乡整体发展水平指标、城乡协调发展水平指标及时间指标的三维坐标系统,并通过转化为二维“九宫格”坐标系统的方法,提出一种包含时序数据和截面数据的城乡统筹水平综合评估的方法论,定量地测评一个区域内各城市在某个特定时间段内的城乡统筹演化特征。本文将城乡统筹水平分为经济、产业、基础设施、公共服务4个方向,对川渝19市2006-2011年间城乡统筹演化特征进行了分类研究。研究结果表明,川渝19市在城乡经济和公共服务统筹方面整体差距缩小且成效显著,而在产业和基础设施统筹方面城乡差距仍在拉大;成渝二市的整体成效远超过区域内其他城市。上述研究成果可对川渝19市优化城乡统筹发展方向提供理论指导和方法论工具,亦可为国内其他地区城乡统筹成效的测评方法提供指导与示范。 相似文献

In the last decades, the development of transport infrastructure has been necessary because of the population increase and expansion of urban centres. Infrastructure development leads to modification and changes in areas characterized by high human population density. The lack of adequate transport infrastructure inhibits local economic and social performance. In the period of economic stability (from 1970 to 1990), important roads that increased the connectedness of the Kolubara District (Western Serbia) with other parts of the country and the surrounding countries were built, but there is still a need for the construction of new roads. In order to examine the attitude of the local population in regard to transport infrastructure, a survey was conducted using a questionnaire consisting of closed questions. This topic is one that has not previously been examined. The data obtained were analyzed statistically and showed that local people have a positive attitude towards the existing infrastructure and towards the construction of new roads. There are statistically significant differences between the attitudes of the local population in different municipalities. The results from this research offer an opportunity to develop guidelines which can influence traffic development in these and similar areas. 相似文献

ABSTRACTDue to increased attention on environmental issues, industrial sustainable restructuring is high on the research agenda. The article adds to the literature through an analysis of a restructuring process within a Norwegian process industry cluster. By introducing an analytical framework combining the concepts of entrepreneurial discovery process and path dependency theory, the article offers a deeper understanding of the role of various types of actors in processes of restructuring. The authors categorise the actors as either firm-level entrepreneurs or system-level entrepreneurs on the basis of their motivation. While the former are motivated mainly by firm success, the latter find their motivation mainly in developing systemic factors. The analytical framework suggests a stepwise analysis of the restructuring, and in each step, the significance and interplay between the two types of entrepreneurs are discussed. Finally, the authors discuss the potential for new path development following from this process. The case study illustrates the important role of system-level entrepreneurs as facilitators and of firm-level entrepreneurs as utilisers of opportunities. The empirical case demonstrates that the two types of entrepreneurs are highly interactive throughout the restructuring process. The article contributes to existing literature by advancing the actor perspective in new path development. 相似文献

北京地区景观城市化进程对暴雨过程的影响——以“7·21”暴雨为例 总被引:1,自引:0,他引:1
利用美国环境预测中心(NCEP)和美国国家大气研究中心(NCAR)等美国科研机构开发的气象模式WRF 3.8版本,采用北京地区不同时期的土地利用数据,选取影响北京的一次典型暴雨过程,应用包含多层城市穹顶模式的模式参数化方案对其进行模拟研究。从小时降水模拟结果来看,景观城市化区域(城市下垫面)的扩张使得暴雨持续更久,使用2010年土地利用数据模拟的2012年7月21日暴雨过程小时降水量大于16 mm的时长较使用1990年土地利用数据模拟的结果增加了1 h;从累积降水结果来看,使用2010年土地利用数据模拟的24 h累积降水大于150 mm的区域较使用1990年土地利用数据模拟的结果增加了1534 km 2。本文中模拟的逐小时降水与实际情况存在一定的差距,未来的工作会深入研究模式的参数化方案和降水产生的机理进而深入地研究景观城市化进程对暴雨过程的影响。进一步研究需针对城市人为活动产生的大气气溶胶粒子、景观城市化密度变化等因子,探究景观城市化对暴雨的可能影响。 相似文献

以演化经济地理学为理论基础,综合经济地理学、产业经济学等相关研究成果,认为中国高新技术产业的形成与发展是本地要素与全球力量、历史条件与现实努力、技术创新与制度变革共同作用的结果,并构建了基于多尺度、多要素的中国高新技术产业分叉动力机制分析框架。同时,以武汉市作为案例区,通过梳理武汉市生物产业形成和演化历程,总结影响其生物产业发展的要素和作用形式。研究发现:生物产业与本地光电子产业之间的技术联系、高校和研究所、以及企业本身仅仅是决定生物产业在武汉市形成的一部分因素,地方政府、跨国公司和留学归国人员等主体也是促成生物产业“生根发芽”的重要主体,它们在武汉生物产业发展的各个阶段,作用程度是不同的。这一点是区别于欧美发达国家以技术为核心的产业分叉研究的,也在一定程度上反映出中国目前的高新技术产业发展仍然停留在“量的扩张”阶段,与欧美发达国家以“质的提升”为主的发展本质有所不同。 相似文献
