基于内生交易费用的农村集体资产股份制改革

以内生交易费用的视角考察现阶段集体资产股份合作制改革,发现股权集体股的设置导致部分资产产权不清晰,股权封闭和政经不分带来合作社的内部监督失效和激励机制不足,从而引起村干部管理者寻租、偷懒等机会主义行为,增加了合作社治理的内生交易费用。苏州市通过集体股确权到户和股权固化,实施合作社“代理记账”,建立村集体财务监管平台和资产交易平台,实现“政经分离”及开放治理等一系列改革措施,明晰了集体资产产权主体,建立了有效的激励约束机制,有利于减少合作社代理人机会主义行为,降低了合作社治理的内生交易费用。苏州经验表明,在农村集体资产股份合作制改革过程中,政府主导力量的恰当发挥是改革的成功前提,同时也要尊重合作社治理的内生动力;通过赋予农民清晰完整的股权,建立顺畅的股权流转体系,有利于合作社内部治理体制的完善;合作社管理者的行为规范还有赖于政府实施的外部监督机制。     

Functional Partial Linear Single‐index Model

This paper deals with the problem of predicting the real‐valued response variable using explanatory variables containing both multivariate random variable and random curve. The proposed functional partial linear single‐index model treats the multivariate random variable as linear part and the random curve as functional single‐index part, respectively. To estimate the non‐parametric link function, the functional single‐index and the parameters in the linear part, a two‐stage estimation procedure is proposed. Compared with existing semi‐parametric methods, the proposed approach requires no initial estimation and iteration. Asymptotical properties are established for both the parameters in the linear part and the functional single‐index. The convergence rate for the non‐parametric link function is also given. In addition, asymptotical normality of the error variance is obtained that facilitates the construction of confidence region and hypothesis testing for the unknown parameter. Numerical experiments including simulation studies and a real‐data analysis are conducted to evaluate the empirical performance of the proposed method.

国家投资科研项目成果的知识产权归属探讨

通过对国家投资产生的科研成果现状的分析以及与国外的相关政策的对比,讨论在不同的情况下,有可能发生的知识产权归属争议;其次,讨论在职务发明、非职务发明、有合同约定、没有约定等情况下怎样理顺权属关系。并对今后知识产权在归属方面的发展趋势作了较为深入的探讨。国家的法律或者政策应该在有效地处理和化解来自各方的权属 纠纷和矛盾,充分调动国家、集体和个人的积极性,鼓励在知识经济条件下努力创造出更多、更有价值的知识产权方面,发挥更大的作用。     

行为目标偏离、规模扩大与利润率降低——对国有企业规模不经济的一种解释

我国国有企业经历过一个亏损的阶段,国有企业的规模与经济利润并不对称.国有企业的行为目标的偏离,使得国有企业的规模不断扩大,并最终出现规模不经济.必须实行"政企分开",培育有效的竞争机制,打破某些企业的垄断局面,让国有大中型企业逐步分解成依赖市场交易的多个主体,缩小企业规模.

房地产案件执行实务问题

人民法院的执行,是人民法院按照法定程序、运用国家强制力,强制义务人履行已经发生法律效力的判决、裁定、调解书以及其他法律文书所确定的义务的司法活动.其任务和目的是依法强制义务人履行生效法律文书所确定的义务,保障权利人的权利得以实现.在房地产案件执行实务过程中,由于房地产自身在财产价值、使用功能、取得程序等方面存在其特殊性,所以执行时应根据其不同的特点,采取相应的执行措施和方法,以达到最大保护相关权利人合法权益的目的.     

Effects of a ball-backrest chair on the muscles associated with upper crossed syndrome when working at a VDT

This study examined the effect of a ball-backrest chair on the weakness and tightness of muscles associated with upper crossed syndrome when working at a visual display terminal (VDT). The surface electromyography (EMG) was recorded from the serratus anterior, middle trapezius, and upper trapezius muscles of 20 adults as they performed VDT work, which are known as the weakened and tightened muscles of upper crossed syndrome. The recorded signals were averaged and normalized to the mean amplitude of the EMG signal obtained during submaximal reference voluntary contractions. The significance of differences between the use of a general-purpose backrest and a ball backrest was tested by paired t-test, with the significance cutoff set at alpha=0.05. The activities of the serratus anterior and middle trapezius muscles increased and that of the upper trapezius muscle decreased when sitting in a ball-backrest chair compared to when sitting in a chair with a general-purpose backrest (p<0.05). These results indicate that the use of a ball-backrest chair reduces the risk of patients with upper crossed syndrome developing muscles soreness or injury related to overuse when working at a VDT.
