中国城市化进程效率估算及影响因素分析

本文基于2008—2012年中国285个地级市的数据,运用双边随机前沿模型测算了中国城市化进程的前沿水平以及实际水平相对前沿水平的偏离程度。结果发现,下偏效应大于上偏效应,即中国城市化进程整体表现为滞后,并且发现投资作用和政府作用在影响城市化进程中的表现为负向,另外城市化进程也表现出地区间的不平衡。最后根据本文的发现,提出相应的建议。     

中国林区贫困现状及解决对策研究综述

林区有着丰富的自然资源,但是近年来,林区社会经济落后以及林农的贫困成为我国现阶段较为显著的现象,同时也成为影响林业发展以及整个社会发展的一个迫在眉睫的问题。林区贫困问题引起了国内外学者的极大关注,本文主要论述了我国林区贫困的现状,并介绍了目前较为典型的5个解决林区贫困的方法和对策：即生态移民、开发非木材林产品、森林旅游、中央和地方政府的扶持、发展教育。     

区域产业文化与人力资源优化配置研究

区域经济发展依赖于区域产业的发展,区域产业竞争力则体现为区域资源整合力,尤其是区域人力资源的优化配置.区域产业文化不仅具有区域性、宽松性和产业群人才观三大特征,还具有促进区域人力资源优化配置的功能.区域产业文化建设需要政府、企业、科研机构等各种区域利益相关者在健全法规、扶持核心企业、提高企业积极性和发展中介组织等方面共同努力.     

基于潜类别随机前沿的区域创新效率及其影响因素分析

运用可根据研究对象的潜在属性内生分组的潜类别随机前沿模型,采用1999-2012年中国各省区数据,研究各省区的创新效率及影响因素。结果表明:以人力资本水平和基础设施状况为条件变量,将全国各省区分成两个技术类别,分别有各自的技术前沿和函数形式,A类别中上海市的创新效率最高,B类别中河北省的创新效率最高;平均来看,各类的创新效率均呈上升趋势,贸易开放、产业结构和金融发展对创新效率均有显著的正向作用,同时创新效率在各类内部均存在俱乐部收敛。     

Generalized empirical likelihood inference in partial linear regression model for longitudinal data

In this paper, empirical likelihood inference for longitudinal data within the framework of partial linear regression models are investigated. The proposed procedures take into consideration the correlation within groups without involving direct estimation of nuisance parameters in the correlation matrix. The empirical likelihood method is used to estimate the regression coefficients and the baseline function, and to construct confidence intervals. A nonparametric version of Wilk's theorem for the limiting distribution of the empirical likelihood ratio is derived. Compared with methods based on normal approximations, the empirical likelihood does not require consistent estimators for the asymptotic variance and bias. The finite sample behaviour of the proposed method is evaluated with simulation and illustrated with an AIDS clinical trial data set.     

Testing Treatment-Covariate Interaction in a Nonparametric Analysis of Covariance Model

We consider a recently introduced nonparametric model for Analysis of Covariance and derive an asymptotic test for interaction between covariate and treatment. Furthermore, we suggest data depth techniques to obtain joint confidence regions for the covariate effects in this model.

The finite sample behavior of the asymptotic method is evaluated in simulations. Application of the procedures is illustrated using an epileptic seizures and chemotherapy data set.     

Xinhai remembered: from Han racial revolution to great revival of the Chinese nation

This article turns three different analytical mirrors onto the Xinhai Revolution – 1911, 1961, 2011 – in order to interrogate its evolving significance in the minds of China's Han ethnic and ruling elite. In particular, it seeks to demonstrates the discursive appropriation of the Qing nomadic frontier in the ways in which the 1911 Revolution is remembered and commemorated, exploring both the temporal and spatial dimensions of this appropriation, and how the revolution shifted from a bloody Han racial insurrection against Manchu power and privilege to a heroic celebration of the revival of a multiethnic Chinese nation-state in the face of foreign imperialism and oppression.     

长安东汉作家及其地域分布略考

东汉是中国古代文学发展的重要转型时期,东汉虽然已经建都洛阳,但长安文化仍然对东汉产生了重要影响。东汉长安作家是东汉地域文学的代表,通过爬梳有关史料,对东汉"三辅"京兆尹、左冯翊、右扶风39城、52位作家的创作事迹和地域分布做了考证整理,并进而总结了东汉长安文学四个方面的创作特征以及对后世的影响。     

特区移民文化建构探析

移民文化在特区经济发展中有着举足轻重的作用。实证分析结果表明，外来人口在常住人口中的比例与特区经济发展成正比。大量的外来人口除了直接参与经济建设贡献力量外，并形成移民文化推动本土文化重构更新，促进经济的发展。文章就如何吸引外来人口，进行文化重构，提出了若干建议。     

On Second-Order A-, D- and E-Minimax Designs for Estimating Slopes in Extrapolation and Restricted Interpolation Regions

Summary

The concepts of D-, A- and E-minimax optimality criteria of designs for estimating the slopes of a response surface are considered for situations where the region of interest may not be identical to the experimental region. Optimal second-order designs are derived for the situation where the experimental region and the region of interest are both hyperspherical with a common centre. The dependence of the optimal design on the relative sizes of the regions is investigated. Further, the perfomance of designs optimal for one region in estimating slopes in other regions is also examined.
