城市土地集约利用时空特征研究——以广东省为例

采用层次分析法构造广东省城市土地集约利用评价指标体系，对1998～2005年以来21个地级市城市土地集约利用进行综合评价：运用Spearman秩相关系数和聚类分析法对评价结果进行时空分析，从区位、经济等方面探讨城市土地集约利用空间差异的原因，并提出相关建议。     

Triple jump about urban land potential release in China

Recent two decades, the great changes take place in China, especially in land use area. After the marketization, the urban land potential of China releases gradually. Three models in this paper show the three stages of reforming land use system. This paper will give a clear picture of urban land use in China that spans nearly thirty years.

Stop and Go Agricultural Policies with a Land Market

This article studies the design of farm policy in the presence of asymmetric information about farmers' productivity, a government objective to insure farmers a minimum "parity" income, an endogenous land rent, and diminishing returns on alternative (nonprogram crop) land uses. In this setting, acreage set asides are never part of an optimal farm policy, although compensated acreage limits are. When there are new farmer entrants who cannot be excluded from farm programs, optimal policy takes the form of a pure voluntary acreage limitation—or "buyout"—program in which high-cost producers participate and low-cost producers do not.     

Land tenure and rental in Western Sudan

This paper reports on aspects of land tenure in western Sudan, especially the nature of tenure insecurity and the functioning of the land rental market. The active land rental market accounted for about one-third of cultivated land. Patterns of land rental transactions, and tests of the importance of insecurity in renting land, where the owner may not be able to reclaim land rented out, do not support the presumption that rental markets perform poorly. The role of the sheikh as administrator of village land, and the claims of large landowners to vast tracts, are, however, important political problems that must be resolved before attempts at ‘rationalizing’ land tenure.     

农村经济的“第二个飞跃”与农用土地制度改革

土地制度的安排与改革决定着农村经济发展的前程。我国农业的改革和发展,要有两个飞跃:第一个是实行以家庭联产承包经营为主的责任制;第二个是发展适度的规模经营,发展合作经济。现行土地制度制约着第二个飞跃的实现,需要调整和完善。土地私有化不是我国土地制度改革的方向。土地制度改革在于适应现代农业建设的需要,构建农地财产权新的框架,以利于农业产业化经营,发展多种形式的适度规模经营。     

构建农村和谐社会的思考

构建农村和谐社会,应当树立正确的农民增收观,促进农民持续快速增收,缩小城乡差别;加快农地产权制度改革,解决农地矛盾和纠纷;加快农村基层组织制度和县乡行政改革,解决农村干群矛盾;加快农村教育发展,改进农村教育质量,提高农民素质;加大再造秀美山川工程监管力度,消除工作中存在的不实、不公等因素;加快农村社会保障制度建设,消除农民的后顾之忧.     

从系统论的角度看集体建设用地可持续利用

土地可持续利用是一个系统论问题,集体建设用地和城市建设用地应该是土地系统中两个平等的子系统.从系统的角度通过分析当前集体建设用地利用中存在的问题,提出了实现集体建设用地的可持续利用应当遵循的政策建议.     

Land use externalities, open space preservation, and urban sprawl

Parcel data on residential land conversion are used to investigate how land use externalities influence the rate of development and modify policies designed to manage urban growth and preserve open space. Several “smart growth” policies are found to significantly influence land conversion, including a development clustering policy that concentrates development and generates preserved open space. In addition to directly affecting a parcel's hazard rate of conversion, this policy is found to affect neighboring parcels' conversion by generating a positive open space externality that hastens their development. The implication that the clustering policy could generate a more sprawled pattern of development is explored using spatial simulation.     

我国城市化危及土地资源持续利用的立法原因探析

随着我国城市化进程的不断加快 ,土地资源供给的有限性与人们对土地资源需求的无限性之间的矛盾日益突显。而在此背景下重新修订公布的《土地管理法》在涉及建设用地需求的无限扩展与农业用地数量的持续下降这两个突出问题上 ,并没有明确政府的职能定位 ,也反映出了相关制度的模糊性。本文就此进行了探讨。
