区域经济一体化与中国工业化发展

中国工业化发展所必须兼顾的两个目标是:赶超国际产业发展前沿与发挥中国比较优势。而区域经济一体化组织的蓬勃发展与中国积极参与的态势为中国通过国际合作提高工业化水平提供了条件,中国应利用好亚太经合组织和中国—东盟自由贸易区这两个经济一体化组织来接受技术转移和产业转移,提高中国工业化水平,扩展中国工业的比较优势及利用一体化成员的资源发展中国工业。     

论形而上学与“形”的关系

形而上学作为对自然、现实的组成和结构的本体性研究,其理论特点之一是与“形”的内在关系。“形”（ειδοζ）作为“理念”（ιδεα）的显现,是形而上学思想的基本语词,并作为“善”的表现而成为伦理学、政治学的基础。以考察形而上学与“形”的初始关系,梳理形而上学发展与“形”概念演变关系（“形”在形而上学史发展中的概念层次有“相”“形式”“观念”“概念”等）为线索,归纳形而上学与“形”的内在关系特点,得出：形而上学与“形”关系的奥秘在于人的理论观点。以此分析,拟提供一种对于形而上学的合理理解。     

The effects of landscape scale on greenery and traffic relationships with urban birds and butterflies

Actions and policies to enhance biodiversity in the urban landscape must match the spatial scale at which biodiversity responds to the management and target variables. To this end, we compare the importance and effect of different kinds of greenery cover and road-lane density on bird and butterfly species richness between two landscape scales: 50-m versus 126-m radii around point counts (equivalent to areas of 0.8 h and 5 ha, respectively). We also compared the results against those of an earlier study using 500-m walking transects with widths of 100 m (i.e., 5 ha). Road lane density was more important at the 126-m than 50-m radius for both birds and butterflies. For birds, natural vegetation or forest cover and cultivated shrub cover were also more important at 126-m radius whereas the cultivated tree canopy cover was more important at 50-m radius. Cultivated tree cover and natural vegetation or forest cover were positively associated with species richness while road lane density and cultivated shrub cover were negatively associated with species richness. The results from point counts generally corroborate the results from the transects-based study, except that the short-duration point counts performed poorly in sampling butterflies. Our results indicate that in designing urban greenery policy, the plot sizes of individual developments is an appropriate spatial scale for the stipulation of tree cover targets, while urban planners have more flexibility to allocate natural greenery at broader spatial scales.

Generalized M-estimation for the accelerated failure time model

The accelerated failure time (AFT) model is an important regression tool to study the association between failure time and covariates. In this paper, we propose a robust weighted generalized M (GM) estimation for the AFT model with right-censored data by appropriately using the Kaplan–Meier weights in the GM–type objective function to estimate the regression coefficients and scale parameter simultaneously. This estimation method is computationally simple and can be implemented with existing software. Asymptotic properties including the root-n consistency and asymptotic normality are established for the resulting estimator under suitable conditions. We further show that the method can be readily extended to handle a class of nonlinear AFT models. Simulation results demonstrate satisfactory finite sample performance of the proposed estimator. The practical utility of the method is illustrated by a real data example.     

Genericity and Robustness of Full Surplus Extraction

We study whether priors that admit full surplus extraction (FSE) are generic, an issue that becomes a gauge to evaluate the validity of the current mechanism design paradigm. We consider the space of priors on the universal type space, and thereby relax the assumption of a fixed finite number of types made by Crémer and McLean (1988). We show that FSE priors are topologically generic, contrary to the result of Heifetz and Neeman (2006) that FSE is generically impossible, both geometrically and measure‐theoretically. Instead of using the BDP approach or convex combinations of priors adopted in Heifetz and Neeman (2006), we prove our genericity results by showing a robustness property of Crémer–McLean mechanisms.

基于犹豫概率模糊语言集的改进MULTIMOORA决策方法

为解决犹豫环境中由随机性和模糊性引起的不确定性对实际决策造成偏差的多准则群决策问题,文章提出一种基于犹豫概率模糊语言的改进MULTIMOORA决策方法。首先构建各决策者的犹豫概率模糊语言决策矩阵,利用熵值法与离差最大化和距离最小化法得到决策者权重;利用犹豫概率模糊加权平均算子将各决策者的决策矩阵聚合为综合矩阵,进而通过改进的MULTIMOORA方法得到最终排序结果;最后通过物流园区合作商选择的算例分析验证该算法的可行性和有效性,并与TOPSIS法、VIKOR法及HFL-MULTIMOORA进行对比分析。     

Test for high dimensional regression coefficients of partially linear models

Abstract

Partially linear models attract much attention to investigate the association between predictors and the response variable when the dependency on some predictors may be nonlinear. However, the hypothesis test for significance of predictors is still challenging, especially when the number of predictors is larger than sample size. In this paper, we reconsider the test procedure of Zhong and Chen (2011 Zhong, P., and S. Chen. 2011. Tests for high-dimensional regression coefficients with factorial designs. Journal of the American Statistical Association 106 (493):260–74. doi:10.1198/jasa.2011.tm10284.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) when regression models have nonlinear components, and propose a generalized U-statistic for testing the linear components of the high dimensional partially linear models. The asymptotic properties of test statistic are obtained under null and alternative hypotheses, where the effect of nonlinear components should be considered and thus is different from that in linear models. Through simulation studies, we demonstrate good finite-sample performance of the proposed test in comparison with the existing methods. The practical utility of our proposed method is illustrated by a real data example.
