开放和垄断:二元经济结构与经济增长路径

中国经济存在开放部门与垄断部门并存的二元结构。垄断部门开放步调缓慢压缩了开放部门的行业宽度 ,使开放部门投资过于拥挤 ,增长率趋于下降 ,对今后二十年保持整体经济的高速增长十分不利。加速开放垄断部门 ,将有力促进经济增长。开放垄断部门必须从转变政府主权机制入手     

Dynamic component detection in a multifactor model for stock returns

Summary In this paper the factorial structure of some asset returns quoted at the Milan stock exchange is analyzed in order to detect the presence of a dynamic component. The maximum likelihood estimates of the dynamic model, for which a space-state representation and the Kalman filter were used, are compared with the estimates of the static model via the information criteria. There is no evidence of dynamic factors underlying the analyzed samples of asset returns, while one static factor seems to be relevant.

基于市场价值的技术资产评估模型的修正--兼与梁莱歆教授商榷

采用经典的资产价值评估方法确定技术资产价格难以实现公允、公正的要求,难为交易双方接受。只有基于技术资产的市场价值才能为交易双方建构公允、公正的评估模型,确定合理的价格区间。“基于市场价值的技术资产评估研究”选择了科学的研究视角,但具体模型存在问题,本文将基于同一原理对其进行修正。     

社会资本对城乡老年人健康影响的实证研究——基于CGSS混合截面数据

利用2013年、2015年中国综合社会调查(CGSS)的混合截面数据,采用二元logistic回归、OLS回归模型,从生理健康和心理健康二个维度,综合考察了社会资本对城乡老年人健康的影响,并检验了社会融合学说及网络关系学说两个理论.研究发现:个体社会资本与集体社会资本均对老年人的生理与心理健康产生显著正向作用,社会经济地位、收入和教育都对老年人身心健康有正向影响,性别和年龄会影响老年人的生理健康,而婚姻会影响老年人的心理健康,家庭规模的影响作用不显著.但在考虑城乡二元结构差异时,个体社会资本对城市老年人的生理与心理健康影响不显著,而家庭规模对农村老年人的心理健康产生显著正向作用.因此,需要促进城市老年人社会交往,提高老年人的社会经济地位,鼓励农村孩子常回家看看,共同营造一个“健康老龄化”的社会.     

Evaluating Weight of Evidence in the Mystery of Balkan Endemic Nephropathy

Balkan endemic nephropathy (BEN) is a chronic, progressive wasting disease of the kidneys, endemic in certain rural regions of the Balkan nations Croatia, Serbia, Bulgaria, and Romania. It is irreversible and ultimately fatal. Though this disease was first described in the 1950s, its causes have been a mystery and a source of much academic and clinical contention. Possible etiologic agents that have been explored include exposure to metals and metalloids, viruses and bacteria, and the dietary toxins aristolochic acid (AA) and ochratoxin A (OTA). AA is a toxin produced by weeds of the genus Aristolochia, common in Balkan wheat fields. Aristolochia seeds may intermingle with harvested grains and thus inadvertently enter human diets. OTA is a mycotoxin (fungal toxin) common in many foods, including cereal grains. In this study, we analyzed the weight of evidence for each of the suspected causes of BEN using the Bradford Hill criteria (BHC): nine conditions that determine weight of evidence for a causal relationship between an agent and a disease. Each agent postulated to cause BEN was evaluated using the nine criteria, and for each criterion was given a rating based on the strength of the association between exposure to the substance and BEN. From the overall available scientific evidence for each of these suspected risk factors, AA is the agent with the greatest weight of evidence in causing BEN. We describe other methods for testing causality from epidemiological studies, which support this conclusion of AA causing BEN.     

二元结构、实际汇率与巴拉萨—萨缪尔森效应——基于面板门限模型的实证分析

运用Hansen提出的面板门限模型,以二元结构为门限变量,研究了43个国家1980~2010年不同收入国家,基于二元结构变化的巴拉萨—萨缪尔森效应的大小(B-S效应),研究发现:二元结构对B-S效应的影响存在明显的双门限效应,高收入国家不存在二元结构问题,其B-S效应显著;中等收入国家基本上跨过了第一门限值,其B-S效应存在,但弱于高收入国家,而低收入国家基本不存在B-S效应;表明在不同二元结构下,由于工资不会同劳动生产率同步增长,劳动生产率对实际汇率的存在不完全传导机制,可以解释"人民币汇率之谜"。     

"玄同"之境与"社会状态":两种不同的主客超越路向

马克思在其《1844年经济学-哲学手稿》中发动了哲学革命,克服了西方两千余年的形而上学传统,超越了二元对立的世界观,实现了哲学向现实的人的世界的回归。这同老子的“玄同”之境十分相似,但又超越其上,老子的玄同论是“未完成的人道主义”或者“未完成的自然主义”。     

A Push Toward Equality: Processes Among Dual‐Career Newlywed Couples in Collectivist Culture

This study examines gender construction among dual‐career newlywed couples in a collectivist culture. A qualitative analysis of in‐depth interviews with 20 heterosexual Singaporean couples reveals aspects of the collectivist norms (e.g., doing family, we‐consciousness, marrying one's equal) that are favorable toward the development of gender equality. Additionally, as couples respond to the political and social pulls of economic development, they begin to organize their relationship around both careers. Incorporating egalitarian values becomes a pragmatic move carried out through five direct processes: (a) career as central to the relationship, (b) flexible allocation of household duties, (c) open dialogue regarding conflict, (d) equal say in decision making, and (e) internal self‐reflection. Implications for future research are addressed.     

略论中国近现代社会文化背景的演变对翻译的影响

中国近现代文化背景是由鸦片战争前的封建传统文化单一模式逐步转向西方文化强势进入模式 ,然后转向当代多元共生的模式。这里分析了中国近现代历史文化背景的演变对翻译选材和翻译标准的影响 ,认为在其影响下翻译选材经历了由自然科学向社会科学、文学等所有领域逐步扩大的过程 ,翻译标准经历了由“信、达、雅” ,向“宁信勿顺”、“化境” ,而至“一定制约性 ,一定自由度”的过程 ,指出文化背景对翻译有着巨大的制约和推进作用 ,新的翻译标准应该包括“顺应社会文化背景”这一点。     

中外企业会计准则—合并财务报表的比较研究

通过对国内外现行会计准则的关键部分—合并财务报表的比较研究,可以看出不同国家在合并会计的理论和实务领域里存在着巨大的差异。提出了西方国家的合并报表理论和实务有许多东西可以借鉴。应采纳世界各国合并报表表现方法中的一切有价值的思想和最新成果,以重新优化和组合现有的合并报表理论和方法,形成自己的合并报表理论体系。
