建国初期闵行镇归属问题研究

明代中后期,闵行镇凭借其便利的交通条件与繁荣的棉花种植业,成为上海县重要的商业市镇。近代以来,随着上海城市的发展,闵行镇与上海城区间经济联系不断密切,政治地位也日趋重要。新中国成立初期,优先发展重工业的国家政策与华东沿海地区的战略地位,使得民国时期奠定重工业基础的闵行镇备受各方重视。在国家政策、经济体制、地方利益等因素的综合作用下,闵行镇最终由江苏省上海县划归上海市。     

The awkward years: defining and managing famines, 1944–1947

Abstract

Famines in the years immediately after World War II occurred during a period of global flux, as international famine response evolved from its ambitious, early twentieth century goals toward more modest, technocratic objectives during the second half of the century. For economists, social scientists and politicians immersed in the world of emergency food aid, these were uncertain, awkward years for famine relief. Herbert Hoover’s idealistic large-scale projects of famine relief that had dominated the first three decades of the century had been proven to be expensive and of limited efficacy, but Cold War loyalties had not yet taken over as the primary logic behind large-scale humanitarian assistance projects. Ultimately, when faced with famine conditions between 1944 and 1947, states and experts balanced a call to action against pragmatism that recognized famines were also politically expedient events that could weaken rural resistance to governance and simplify wartime and postwar administration. Ultimately, both science and humanitarian concerns learned to orient themselves toward economic expediency in these awkward years.     

Re‐sewing the Sewn: An Ethnographic Record of Repair and Reuse of Sewn‐plank River Boats in Goa,India

The tradition of fastening planked boats using sewing is characteristic of the Indian Ocean region. Despite known disadvantages of sewn boats, including that perishable materials need regular maintenance and repair, operators of boats used in the sand‐mining industry of Goa still see potential in discarded sewn boats. The problems, raw materials used, technology, and process of re‐sewing and repairing these boats to give them a second life are reported and discussed here.     

Polycentricity as spatial imaginary: the case of Helsinki City Plan

The paper analyses with a case study the use of a widely applied normative concept of polycentricity as spatial imaginary. The case study of Helsinki City Plan and the conflict over its city-boulevard scheme draws on qualitative content analysis of planning documents and expert interviews. It demonstrates the instrumental role of multiple interpretations of polycentricity in tension-ridden metropolitan and city-regional spatial planning. The conflict reveals how the conceptual ambiguity of polycentricity and the institutional vagueness of city-regional planning have together enabled advancing contradictory political aims under their guise. In conclusion, the paper emphasizes the persuasive performativity and fluidity of polycentricity as a spatial imaginary in multi-scalar planning settings.     

中国城市群空间结构演化的影响因素分析——基于铁路客运的功能联系视角

以中国13个城市群为研究对象,采用铁路客运班次构造多中心指数来表征基于功能联系的城市群空间结构,在分析城市群空间结构演变基础上重点分析其影响因素。研究发现,基于功能联系视角的城市群空间结构总体呈单中心化趋势,但地区差异化明显,珠三角、山东半岛和闽东南城市群已表现出多中心化特征;城市群空间结构的多中心程度随经济发展水平的提高表现为先单中心后多中心的演变过程;城市群规模的增大和城市间联系加强促进了城市群向多中心方向演化;而面积小、三产比重高的城市群更有利于形成单中心的结构;政府干预作用对城市群空间结构影响并不显著。鉴于不同城市群空间结构演化趋势不同,未来政策取向应该遵从各个城市群自身规律。     

Green cities? Urbanization,trade, and the environment

Is urbanization good for the environment? This paper establishes a simple core–periphery model with monocentric cities, which comprises key forces that shape the structure and interrelation of cities to study the impact of the urban evolution on the environment. We focus on global warming and the potential of unfettered market forces to economize on emissions. The model parameters are chosen to match the dichotomy between average “large” and “small” cities in the urban geography of the United States, and the sectoral greenhouse gas emissions recorded for the United States. Based on numerical analyzes we find that a forced switch to a system with equally sized cities reduces total emissions. Second, any city driver which pronounces the asymmetry between the core and the periphery drives up emissions in the total city system, too, and the endogenous adjustment of the urban system accounts for the bulk of the change in emissions. Third, none of the city drivers gives rise to an urban environmental Kuznets curve according to our numerical simulations. Finally, the welfare‐maximizing allocation tends to involve dispersion of cities and the more so the higher is the marginal damage from pollution.     

BOSERUP BACKWARDS? AGRICULTURAL INTENSIFICATION AS ‘ITS OWN DRIVING FORCE’ IN THE MBULU HIGHLANDS,TANZANIA

Why do farmers intensify their agricultural practices? Recent revisions of African environmental historiographies have greatly enriched our understanding of human–environmental interactions. To simply point at poor farming practices as the main cause of deforestation, desertification and other processes of land degradation is, for example, no longer possible. The contemporary analytical focus is instead on the complex and often unpredictable set of causal relations between societal, ecological and climatic factors. In the literature on agricultural intensification, conventionally defined driving forces, such as population pressure and market demand, remain important explanatory factors despite a growing body of research that suggests more dynamic scenarios of agricultural development and landscape change. This article reports on a case where the common‐sense logic of population pressure theory has dominated the historical narrative of a local process of agricultural intensification among an agro‐pastoral people in north‐central Tanzania. By way of a ‘detailed participatory landscape analyses’ a more complex and dynamic historical process of intensification is suggested, in which the landscape and the process of agricultural intensification itself are in focus. It is concluded that the accumulation of landesque capital has been incremental in character, and that the process of agricultural intensification in the study area has largely been its own driving force based on self‐reinforcing processes of change, and not a consequence of land scarcity and population pressure. This result demonstrates the possibility and usefulness of reversing the Bose‐rupian argument in analyses of agricultural intensification.     

20世纪90年代中国城市居民的文化消费——以北京为例

文化消费的比重较大是小康型消费结构的一个重要标志,20世纪90年代北京城市居民的生活水平率先实现了小康,在居民文化消费支出不断增加的基础上,文化消费的内容日渐丰富,其中最为突出的是教育消费比重增长迅速、书报杂志消费异军突起、文娱消费浪潮不断高涨、旅游消费持续升温、休闲消费成为时尚。随着人们的视野开阔和思想解放,文化消费的领域仍在扩展之中。与乡村居民和其他城市居民相比较,北京城市居民的文化消费水平处于一个较高的位置。
