浙江省农村集体产权制度改革的实证研究——基于嘉兴、丽水农村集体产权制度改革实践的考察

为了研究农村集体产权制度改革的具体进展,对农村集体产权制度改革建言献策,推动改革的不断完善,本研究对嘉兴市、丽水市农村集体产权制度改革实践进行了考察。结果表明,欲进一步深化农村集体产权制度改革,应进一步细化“政经分离”改革的具体内容,在考量中国各地区集体经济发展水平差距较大的现实因素下分步推进,不断反刍集体经济组织的治理机制;弱化集体经济组织成员资格认定的户籍标准,建立以“土地承包关系作为基本生活保障”为核心的成员认定规则,切实保障好集体成员的合法权益;全面培育农村产权流转交易市场,通过立法与政策扶持为农村集体经济的发展壮大保驾护航。     

中国集体建设用地产权制度的现状及演进

为弥补学界对集体建设用地产权制度研究不足,笔者拟运用制度变迁理论,分析集体建设用地产权制度的历史演进过程,从制度需求和制度供给视角探究集体建设用地产权制度的变迁机理和发展方向。研究发现,与国有建设用地产权相比,现行集体建设用地产权明显变现为“同地不同权、同地不同价”。在源于要素价格上升和外部利润积累而引致产权制度变迁需求的背景下,国家供给集体建设用地产权制度的成本-收益结构发生剧烈变化,在可供选择的制度集合内,国家应保证集体所有制平等地位,健全集体内部决策机制,完善使用权直至可交易。集体建设用地产权制度变迁过程是制度需求和制度供给共同作用的结果,社会发展赋予制度需求差异性,全国各地试点为制度供给提供了多样选择集合,最终实现集体建设用地产权制度需求-供给平衡。     

中国农村集体建设用地产权制度改革公共性问题探析

为深入剖析和总结中国集体建设用地产权制度改革试点中出现的问题和治理经验,探索系统推进中国农村集体产权制度改革的路径。本研究运用数据、规范和比较分析方法,对中国农村集体建设用地产权制度改革的公共性缺失问题进行了反思和探讨。从公共性生产逻辑的视角,提出在协调现行市场经济条件下“城乡融合发展的公共利益、集体经济的共同利益和农民的财产权益”基础上,建构以多元主体协同共治为基础,以数字化治理技术创新为保障,以公共基础设施和公共服务改善为支撑,以城乡要素市场双向流动建设为目标的产权制度改革路径。为此,本研究建议进一步明确农村集体建设用地产权制度改革的公共性目标,从城乡融合发展的视角系统地推进各项配套改革措施的完善,并加强对其改革效果的公共性评估。     

The Degree of Centralization of P. R. China’s Construction Industry

The degree of centralization indicates the concentration of production management in a particular industry and is an important indicator to reflect industry and market structures. We use the concentration rate ( ) to analyze the concentration of the construction industry from 2000 to 2005 in P. R. China and compare that industry with others in the country. We also use a Lorenz curve to analyze the industrial structure of P. R. China based on data from P. R. China and developed countries. We conclude that the concentration of the Chinese construction industry definitely has developed; there still exist, however, considerable gaps when it is compared with counterparts in developed countries. We therefore discuss ways to improve the degree of centralization of the Chinese construction industry, based on the laws and regulatory system, market order, and industrial and enterprise structures.     

A Simple Experimental Analysis Method for Reinforced Concrete Bar System Structures - Sectioned Dropping Rigidity Method

In order to solve the problem that the internal force of statically indeterminate prestressed and reinforced concrete bar system structures is difficut to determine when the structures come to the non-elastic state, a simple analysis method of experimental structures' internal force-sectioned dropping rigidity method is brought forward.In this method, according to the loading state of bars, the bars are divided into limited segments by the level of rigidity dropping, and the relative level of each segment is enacted; then the dropping modulus of each segment rigidity will be found by debugging time after time, and the checking point is the key distortion which was gained from the experiment; it is considered that the internal force which is calculated by elasticity analysis at the dropped rigidity can reflect the real internal force of the structures.It is basically proved that the method, which is brought forward in this paper, is effective by comparing its results with those from the experiment of a large size prestressed frame of two spans and single floor, of which the internal force redistribution is considered.     

A new measurement method for mass property parameters

Mass property parameters (mass, center of mass, moment of inertia) are important technology parameters of aircraft. The traditional mass and center of mass measurement uses centroid units, and the moment of inertia measurement torsion units, which can only get results in installing direction. Because of the structural reasons, there is a need to get all high accurate physical parameters in clamping once. To solve this problem, this study merges centroid units and torsion units into one composite unit, installs a table which can tilt and rotation to measure the moment of inertia in different conditions. The moment of inertia and product of inertia relative to three axis are calculated by the method of coordinate transformation. Measurement theory of mass, center of mass and mass moment of inertia are described, the main reason of causing measurement errors is discussed, and the measurement accuracy affected by tilt error is analyzed.
