财政支出行为对城乡基础设施差异影响的实证分析

文章认为,改革开放30年来,我国城乡基础设施的差异不断放大,这趋势主要源自地方政府间的财政支出竞争。在财力既定的条件下,为了吸引资本的流入,地方政府往往以绝对或相对减少农村基础设施投入为手段,保证城市基础设施建设对资金和劳动力的吸引,从而绝对或相对减少对农村基础设施建设的投入。     

建立现代大学制度促进民办高校发展

我国建立现代大学制度迫在眉睫,但我国高校现有的教育体制、模式和观念上的束缚可能是其难以建立的重要原因.分析现代大学制度的相关改革措施,可以发现民办大学独特的办学体制和机制是建立现代大学制度的巨大优势.与改革公立高校相比,大力发展民办大学将是我国建立现代大学制度的一条更为便捷和有效的途径.

马克思恩格斯如何捍卫马克思主义

作为马克思主义的创始人,马克思和恩格斯在创建国际性无产阶级政党的历史进程中,进行了艰苦的理论研究和实践活动,给无产阶级革命斗争奠定了马克思主义的理论基础,提供了强大的思想武器,为建立无产阶级政党作了思想上和组织上的准备;同当时工人运动中存在的各种非马克思主义思想和观点进行了毫不妥协的斗争,划清了马克思主义与非马克思主义的界限,坚决有效地捍卫了马克思主义在无产阶级政党中的指导地位,使马克思主义关于无产阶级革命、无产阶级专政的一些重大理论和原则得到了新的发展,也使国际共产主义运动理论日益走向成熟和完善.     

Regression analysis of informative current status data with the semiparametric linear transformation model

Many methods have been developed in the literature for regression analysis of current status data with noninformative censoring and also some approaches have been proposed for semiparametric regression analysis of current status data with informative censoring. However, the existing approaches for the latter situation are mainly on specific models such as the proportional hazards model and the additive hazard model. Corresponding to this, in this paper, we consider a general class of semiparametric linear transformation models and develop a sieve maximum likelihood estimation approach for the inference. In the method, the copula model is employed to describe the informative censoring or relationship between the failure time of interest and the censoring time, and Bernstein polynomials are used to approximate the nonparametric functions involved. The asymptotic consistency and normality of the proposed estimators are established, and an extensive simulation study is conducted and indicates that the proposed approach works well for practical situations. In addition, an illustrative example is provided.

不对称权力结构、非均衡契约与劳资冲突

从社会契约理论的视角来看,中国改革的实质内涵是从计划交易秩序向市场交易秩序的结构转型,而交易秩序的结构转型必然引致结构内部关系的转变。由于市场交易秩序条件下的企业是一个不对称的权力结构,因而企业内部雇主和雇员之间必然是一种非均衡的契约关系,这种非均衡契约关系超出合理限度是当今劳资矛盾和冲突的根源。解决这个问题的关键是在企业内部建立激励兼容机制和加强政府的外部监督。

Variable selection for recurrent event data via nonconcave penalized estimating function

Variable selection is an important issue in all regression analysis and in this paper, we discuss this in the context of regression analysis of recurrent event data. Recurrent event data often occur in long-term studies in which individuals may experience the events of interest more than once and their analysis has recently attracted a great deal of attention (Andersen et al., Statistical models based on counting processes, 1993; Cook and Lawless, Biometrics 52:1311–1323, 1996, The analysis of recurrent event data, 2007; Cook et al., Biometrics 52:557–571, 1996; Lawless and Nadeau, Technometrics 37:158-168, 1995; Lin et al., J R Stat Soc B 69:711–730, 2000). However, it seems that there are no established approaches to the variable selection with respect to recurrent event data. For the problem, we adopt the idea behind the nonconcave penalized likelihood approach proposed in Fan and Li (J Am Stat Assoc 96:1348–1360, 2001) and develop a nonconcave penalized estimating function approach. The proposed approach selects variables and estimates regression coefficients simultaneously and an algorithm is presented for this process. We show that the proposed approach performs as well as the oracle procedure in that it yields the estimates as if the correct submodel was known. Simulation studies are conducted for assessing the performance of the proposed approach and suggest that it works well for practical situations. The proposed methodology is illustrated by using the data from a chronic granulomatous disease study.
