现代西方产权理论批判

现代西方产权理论是对新古典经济学的修正。科斯等把交易成本、产权等范畴引入经济学分析，以交易成本理论为基础，以科斯定理为核心，形成了产权理论分析的基本框架。产权制度的效率比较和制度演进理论进一步丰富和发展了产权理论。产权理论将分析经济问题的焦点集中到产权和制度方面，比以往资产阶级经济学家更具有眼光。批判地吸收西方产权理论的研究成果对于我国国有产权改革有借鉴意

兼并的产权分析

企业兼并是重新配置社会资源调整企业生产规模的重要形式也是企业组织形式变革 的重要形态十五大以来国有企业兼并作为国有产权重组的重要形式已成为我国改革的热 点从理论上对企业兼并的动因和国有企业兼并的特点作出说明对于现阶段兼并的健康发 展有重要的理论意义和现实意义企业的产权关系和产权结构是企业制度的基础产权界定 不清是我国企业兼并中的突出问题因此本文选择从产权主要是法人财产权出发研究企 业兼并说明兼并的动因兼并中产权的变动和国有企业兼并的产权特点分析兼并与国有 产权重组的关系以及政府在国有企业兼并中的作用 选题意义国外在公司兼并实务方面有大量文献对兼并的动因也有理论研究和实证 分析形...Merger plays an important role in resource reallocation in society and perfecting scale of production and organization structure in firms;Merger in state-owned enterprises (SOEs)has been a focus of China's reform,as an important form of restructuring state-owned economy.So,a theoretical interpretation of the driving force of mergers and of the characteristics of present mergers in China is of ...学位：经济学博士院系专业：经济学院经济研究所_政治经济学学号：B19961600

Recent Developments in Radiationless Transitions

在本文中,我们将介绍运用第一性原理计算包含非谐效应或势能面锥形交叉情况下内转换速率的最新工作。我们同时计算了包含非谐效应的分子吸收和发射光谱,以检验量子化学方法计算得到势能面的准确性。势能面的锥形交叉对内转换过程的影响是学界广泛关注的焦点。本文将介绍如何在内转换速率计算的过程中考虑势能面锥形交叉的影响,并将之运用于吡嗪分子。本文运用绝热近似理论处理了另外一个重要的无辐射过程,分子的振动驰豫过程,并将这个理论应用于水二聚体和苯胺的振动弛豫速率的计算。In this paper,we introduce recent works on the mathematical treatments and the first-principle calculations concerning the internal conversion rates for the cases with anharmonic potentials,and conical intersecting potentials.The simulations of absorption and emission spectra with anharmonic effects are also presented to check the validity of the potential energy surfaces obtained from the quantum chemical calculations.The effect of conical intersection on internal conversion has attracted considerable attention.In this paper a different approach is proposed and applied to pyrazine.Another important non-radiative process,molecular vibrational relaxation,is also treated by applying the adiabatic approximation to the ab initio anharmonic potential energy surfaces.The vibrational relaxation rates in water dimer and aniline are chosen to demonstrate the calculation
