我国增值税类型选择的经济学思考

增值税有生产型、消费型和收入型三种.1994年我国税制改革选择了生产型增值税,对抑制投资膨胀,保证财政收入起到积极作用.随着市场经济的深入发展,我国税制改革应取向于消费型增值税,因其能避免重复征税而有利于分工协作,刺激投资,保护基础产业的发展.     

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。     

阿姆河流域耕地变化及水土匹配特征分析

基于中亚阿姆河流域4个分区1990—2015年间土地利用变化和水资源等数据,运用耕地变化速率、洛伦兹曲线和基尼系数法以及水土资源匹配系数对阿姆河流域耕地变化和水土匹配状况进行了综合分析。结果表明:1990—2015年阿姆河流域耕地以146.74 km²/a的速度在扩张,且各时期、各分区扩张的速度不同;在不考虑咸海来水不断减少、生态持续恶化的前提下,绿洲区匹配状况属比较公平和相对合理状况;阿姆河流域水土资源空间分布存在明显的错位现象;全流域生态用水被农业用水严重挤占,阿姆河流域灌溉面积、灌溉用水量成为影响咸海水量及面积变化的重要因素,是一种不可持续的用水方式。     

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.     

完善农村土地承包经营权的立法思考

农村土地承包经营权制度自从 2 0世纪 70年代末在中国实行以来 ,取得了巨大成就 ,推动了农村社会经济发展。但在实施过程中 ,由于其表现出债权的特征而逐渐暴露出种种弊端。以物权关系改造现行土地承包经营权制度 ,已成为法学界的共识。物权立法应就土地承包经营权的取得、效力、消灭等作出具体详细的规定 ,使之形成一整套完整的土地承包经营权法律制度     

国土资源开发与区域经济发展

国土资源的开发利用对区域经济发展有着基础性的 ,深远的影响 ,我国土地资源、矿产资源、海洋资源开发利用的区域特征已形成 ,但在空间布局、发挥区域资源比较优势、区域国土资源综合利用等方面仍存在一些问题。因此 ,应该在国土资源调查评价、规划、参与世界经济分工协作、法制建设、技术进步等主面采取相应的对策。     

民间组织管理制度的经济学分析

我国现行的"管制型"民间组织管理模式不利于民间组织的发展。通过比较现行管理制度下的成本与收益发现,要推动民间组织管理制度的变革,建立和谐的国家与社会关系,必须放松对民间组织的控制。
