产权市场的外资并购分析

并购活动包括目标甄选、交易实施和企业整合三大步骤。由于证券市场的局限性和场外交易的风险性,产权市场将会成为外资并购理想的主要交易场所。文章以交易实施中的交易市场作为研究对象,重点阐述了外资并购在产权市场中的情况、问题和对策。     

我国农业生态环境恶化的制度成因探析

本文认为,当前我国日益严峻的农业生态环境与现行的农地制度息息相关。通过分析现行农地制度存在的主要问题,及它对农业生态环境可持续利用的不利影响,指出现行农地制度是造成我国农业生态环境日益恶化的主要制度成因。就此,得出应对现行农地制度进行适度调整,建立有利于农业可持续发展的农地产权制度安排;稳定土地承包经营权,规范农地流转制度;实行有利于生态环境的农业补贴方式。     

试论利奥波德的大地伦理观

奥尔多.利奥波德的大地伦理学提出了共同体及其范围扩展、大地伦理学的内涵等观点。他从现代人类所面临的严重生态危机和环境问题入手,总结了关于大地伦理学的观点:改变狭隘的人类中心主义认知观念;树立全新的整体生态伦理观念;维护大自然的和谐共生;人类要关爱一切生命;倡导实际的长久的美丽。     

完善服务贸易数据统计：国外的实践与我国的对策

解决服务贸易数据统计问题被列入乌拉圭回合服务贸易谈判的五点内容之一提交给各国代表讨论 ,这五点内容是 :服务贸易的定义和统计问题 ;服务贸易原则与规则的概念 ;服务贸易多边框架的范围 ;现行国际法规与规则 ;促进与限制服务贸易发展的措施与做法。由于服务贸易是乌拉圭回合谈判的新议题 ,各国对“服务贸易”究竟如何定义存在不同的看法 ,发展中国家仅将居民与非居民所从事的跨国服务视为国际服务贸易 ,即狭义论 ;而发达国家则将所有涉及不同国民或不同国土的服务交易都列入国际服务贸易范畴 ,即广义论。分歧的结果不得不提交给 1988年…     

On Bartlett correction of empirical likelihood for regularly spaced spatial data

Bartlett correction constitutes one of the attractive features of empirical likelihood because it enables the construction of confidence regions for parameters with improved coverage probabilities. We study the Bartlett correction of spatial frequency domain empirical likelihood (SFDEL) based on general spectral estimating functions for regularly spaced spatial data. This general formulation can be applied to testing and estimation problems in spatial analysis, for example testing covariance isotropy, testing covariance separability as well as estimating the parameters of spatial covariance models. We show that the SFDEL is Bartlett correctable. In particular, the improvement in coverage accuracies of the Bartlett‐corrected confidence regions depends on the underlying spatial structures.

Inferences for a Partially Varying Coefficient Model With Endogenous Regressors

In this article, we propose a new class of semiparametric instrumental variable models with partially varying coefficients, in which the structural function has a partially linear form and the impact of endogenous structural variables can vary over different levels of some exogenous variables. We propose a three-step estimation procedure to estimate both functional and constant coefficients. The consistency and asymptotic normality of these proposed estimators are established. Moreover, a generalized F-test is developed to test whether the functional coefficients are of particular parametric forms with some underlying economic intuitions, and furthermore, the limiting distribution of the proposed generalized F-test statistic under the null hypothesis is established. Finally, we illustrate the finite sample performance of our approach with simulations and two real data examples in economics.     

知识分布、衰减程度与产业集群创新模式的内在机制研究

以知识流动为研究视角,将集群创新过程中的知识溢出、吸收能力内生化,构建包含三种创新模式下的产业集群演化模型,重点分析集群知识分布和知识衰减程度与集群创新模式的内在机制及其对创新产出的影响,并进行仿真实验。研究表明：不同知识分布下,混合创新模式的创新产出表现最好,外部吸收创新模式与内部自主创新模式呈现出不同的创新产出演化路径;在外部吸收创新和混合创新模式下,均匀分布型产业集群的创新产出表现最好,集中分布型表现次之,异质分布型表现最差,而在内部自主创新模式下,集中分布型则表现最好;不同创新模式对知识衰减的敏感程度呈现阶段性差异特征。这些结论对产业集群创新和可持续发展具有很好的理论和实践指导意义。     

Performative family: homosexuality,marriage and intergenerational dynamics in China

Using in‐depth interview data on nominal marriages – legal marriages between a gay man and a lesbian to give the appearance of heterosexuality – this paper develops the concept of performative family to explain the processes through which parents and their adult children negotiate and resolve disagreements in relation to marriage decisions in post‐socialist China. We identify three mechanisms – network pressure, a revised discourse of filial piety and resource leverage – through which parents influence their gay offspring's decision to turn to nominal marriage. We also delineate six strategies, namely minimizing network participation, changing expectations, making partial concessions, drawing the line, delaying decisions and ending the marriage, by which gay people in nominal marriages attempt to meet parental expectations while simultaneously retaining a degree of autonomy. Through these interactions, we argue that Chinese parents and their gay adult children implicitly and explicitly collaborate to perform family, emphasizing the importance of formally meeting society's expectations about marriage rather than substantively yielding to its demands. We also argue that the performative family is a pragmatic response to the tension between the persistent centrality of family and marriage and the rising tide of individualism in post‐socialist China. We believe that our findings highlight the specific predicament of homosexual people. They also shed light on the more general dynamics of intergenerational negotiation because there is evidence that the mechanisms used by parents to exert influence may well be similar between gay and non‐gay people.
