The ‘Graying’ of ‘Green’ Zones: Spatial Governance and Irregular Settlement in Xochimilco,Mexico City

This article details the evolving social and spatial dynamics of a planning approach that is now being used to regulate irregular or informal settlements in the conservation zone of Xochimilco in the Federal District of Mexico City. As part of the elaboration of ‘normative’ planning policies and practices, this approach counts, maps and then classifies irregular settlements into different categories with distinct land‐use regularization possibilities. These spatial calculations establish a continuum of ‘gray’ spaces, placing many settlements in a kind of planning limbo on so‐called ‘green’ conservation land. The research suggests that these spatial calculations are now an important part of enacting land‐use planning and presenting a useful ‘technical’ veneer through which the state negotiates competing claims to space. Based on a case study of an irregular settlement, the article examines how the state is implicated in the production and regulation of irregularity as part of a larger strategy of spatial governance. The research explores how planning ‘knowledges’ and ‘techniques’ help to create fragmented but ‘governable’ spaces that force communities to compete for land‐use regularization. The analysis raises questions about the conception of informality as something that, among other things, simply takes place outside of the formal planning system.     

基于用地效率分析的城市区域空间结构极化模型及空间发展战略

不同规模的城市其用地效率具有一定的差异性.本文通过对中国660余个不同规模城市的用地效率分析,在总结和分析了传统城市区域空间结构基本理论和模型的基础上,提出基于城市用地效率分析的城市区域空间结构极化模型.通过理论与实证分析表明,城市发展的方向一极是大型化,发展成为特大城市或超大城市(人口100万-400万);另一极是小...     

论“原乡规划”及其乡村规划思想

原乡规划借鉴老庄哲学顺应自然的无为自化思想,强调在规划过程中以无为作为最高境界,尊重自然,以实现自然境域下人们生活与生产的原真性,规划理念和方法强调人与自然的和谐,主张以自然为本,以居民为本,主张保持好原住民的生活方式,主张为人们提供本色的自然体验和生活体验。原乡规划运用于乡村规划的思想,是拒绝乡村的城市化,使乡村保持好乡村景观和乡村意象,是拒绝让城市病蔓延到乡村。

中国农村土地制度变迁:一个产权的视角

农地制度历来是中国农村变革的关键,其要义在于产权。本文从产权角度对建国后中国农地制度变迁作了简要分析。作者认为,产权的界定与实施决定着产权的经济绩效。土地改革以来各种农地制度创新形式的不同经济绩效都与产权清晰程度和实施机制有关。

Pure rent taxation and allocation of capital in a two-sector open economy: A long-run analysis

In this paper, the long-run incidence of a tax on pure rent is analyzed in an OLG two-sector small open economy, in which one sector produces a capital good and one sector a consumer good. Contrary to what is obtained in a one-sector closed economy, a land rent tax does not necessarily foster nonhumam wealth accumulation and capital formation. The accommodating scheme for the government budget plays a crucial role for the effects of pure rent taxation. A rent tax stimulates nonhuman wealth if distortionary taxes on wealth or on income from nonland inputs are alleviated. The mechanism spurring capital formation is brought into action, instead, only when the rent tax is matched by a fall in capital taxation or, if the capital sector is capital intensive, by an increase in government spending on the capital good.     

The housing question in Japan

This article first examines how bad housing conditions are in Japan based on international comparisons. The next question is whether the extremely high land prices in Japan can be explained by economic logic. We then turn to more specific housing policy questions that are peculiar to or important in Japan, such as the tax advantages of owning land that have caused under-utilization of land and the reasons why the average size of Japanese rental housing is so small.     

房价结构调整与经济结构转型

目前,我国住宅房地产价格明显偏离正常值。对房价结构的分析表明,房价结构中33.86%的资金流向了政府。经过房价结构这一隐秘机制的运行,本来属于居民消费领域的购房资金被转变为政府投资资本,导致经济结构中投资与消费之间的比例失衡。这与我国加快经济结构调整,增加消费在促进经济增长中的比重相悖。为应对上述情况,加快优化房价结构是促进经济结构转型的有力举措。
