伪满洲国制定并实施了一系列统制经济政策。其中,占据突出位置的是"产业开发五年计划"、"北边振兴计划"和"百万户移民计划"。伪满洲国统制经济政策的实质是企图把中国东北沦为日本帝国主义的经济附庸,"以获得为进行长期对外战争提供资源及其他的巩固的策源地",为侵略战争造血、输血,进而为日本帝国的政治、经济服务。  相似文献

Constructing Water Shortages on a Huge River: The Case of Shanghai   总被引:1,自引:0,他引:1       下载免费PDF全文
Shanghai is located on the world's third largest river (by volume). Yet it faces the risk of shortages of drinking water. Many decisions and environmental characteristics have contributed to this threat. First, Shanghai has become dependent on water brought into the municipality by rivers. Second, it has become increasingly reliant on water from the Changjiang (Yangzi River), principally in order to control the levels of pollution in the water that enters its treatment plants. Third, for reasons associated with inter‐provincial administrative arrangements, the city's water intakes are located within the municipality, within the estuary zone and subject to tidal intrusions of salt water. Fourth, at high tide and when the Changjiang's discharge is low, salt intrudes far into the estuary, beyond the current water intakes. If sea levels rise, these intrusions will become more pronounced. Fifth, large‐scale central government infrastructure projects (such as dams and the South‐North Transfer) are altering the hydrological characteristics of the river. Such projects raise the probability of salt water intrusions into the water intake zone. The Shanghai and central governments have thus made a series of decisions that, taken together, have led the municipality to rely on a source of drinking water that is increasingly unreliable and subject to the risk of shortages due to salt water intrusions. Why these decisions have been made – independently – is an important problem for those who would understand the provision of water for cities and the practical efficacy of Chinese governance systems.  相似文献

全球与地方的契合:权力与生产网络的二维治理   总被引:5,自引:2,他引:3  
景秀艳  曾刚 《人文地理》2007,22(3):22-27
企业间关键资源的不均衡引致权力关系的不对称,强势企业得以领导以其为核心的企业网络。由于生产环节的组织和地域上的可分割性,居于权力优势地位的领先公司在全球招募企业组成生产网络。全球购买型领先公司通过外包与地方生产网络建立新的关系拓扑,地方生产网络的治理以全球商品链为纽带,嵌入到以领先公司为主导的全球价值链治理体系中。全球生产型领先公司跨境投资时无法将生产网络全盘复制,以其为主导的跨界生产网络的治理需要通过各种权力的博奕和管理上的互动来实现。  相似文献

With the networking of urban rail transit and the large-scale development of bike-sharing, metro and bike-sharing connection has become the preferred way of daily travel for residents of Xiamen. Current studies mainly identify metro station types based on node and place orientation, lacking behaviour-based investigation. To fill this gap, this study aims to explore the classification of metro stations based on transfer purposes by combining bike-sharing and point of interest data in Xiamen, using buffer analysis, kernel density estimation, and DBSCAN clustering algorithm comprehensively. The results indicate the following. (1) Distinct transfer purposes have significant agglomeration characteristics and present poly-centric spatial pattern, an authentic portrayal of Xiamen's land use function. (2) The heterogeneity of connection flow between different transfer purposes and metro stations is apparent. The distribution of flow and flow direction within the same transfer purpose is also in non-equilibrium. (3) Based on traffic connection analysis, metro stations are divided into seven types: transportation hub, employment-oriented, residence-oriented, job-housing balance, school-oriented, traffic-tourism integration, and business connection types. The obtained results assist in improving the transportation connection environment, perfecting urban land use planning, and enhancing low-carbon and green travel.  相似文献

改革开放以来,为了适应新形势的发展,中央对少数民族干部政策进行了较大幅度的调整。辽宁省各级党委、政府高度重视培养选拔少数民族干部工作,全面贯彻执行党的民族政策,从辽宁省的实际出发,采取有效措施,取得了明显成效。当然,目前辽宁省落实少数民族干部政策也存在一些问题.就是少数民族干部的结构体系存在着比例不合理的同题,主要表现在少数民族干部的数量结构同题、化知识结构问题,少数民族专业技术人才的外流等问题。针对这些问题,笔建议,应通过民族政策的词整及完善,以实现民族干部结构的相对协调。  相似文献

During the first half of the 20th century, when China experienced a new tide of urbanization, a tendency appeared, in which the upper strata moved to the urban center and the lower strata distributed over the marginal area, where poor people formed a new community. This marginal community bore distinctive characteristics no matter in spatial structure or in residents’ life style in the development of modern Tianjin. The lower culture from the marginal areas and the upper culture from the foreign concessions constituted an interaction urban cultural structure in modern China.
