企业组织创新与生产率关系的实证研究：以纺织业为例的讨论

本文结合国际创新实证研究新动态,在将创新定义扩展的基础上,以纺织业为例,分析组织创新对于企业生产率的影响。实证研究表明,在企业分规模、分经济类型和分地区的情况下,组织创新对于企业生产率的提高具有显著的影响,只是影响程度各有不同。因此,促进企业组织创新,拓展对创新观念的认识,从而提高企业生产率是应当考虑的企业增长路径之一。     

论中国古典建筑砖石雕刻的审美文化内涵

古典建筑砖石雕刻艺术是一种有目的的装饰和有意味的审美形式.一方面,砖石雕刻对传统哲学观念进行创造性的转换;另一方面,在其创作过程中,始终保留着对传统精神的理解与诠释,因而,审美与文化是砖石雕刻艺术存在的基础,也是影响装饰艺术思维观念与审美取向的一个重要因素,时代背景、人文观念、宗教艺术以及民俗风情都对中国古典建筑雕刻艺术产生了深远的影响.

Parameter estimation of a composite production function model based on improved artificial fish swarm algorithm and model application

The traditional Cobb–Douglas production function uses the compact mathematical form to describe the relationship between the production results and production factors in the production technology process. However, in macro-economic production, multi-structured production exists universally. In order to better demonstrate such input–output relation, a composite production function model is proposed in this article. In aspect of model parameter estimation, artificial fish swarm algorithm is applied. The algorithm has satisfactory performance in overcoming local extreme value and acquiring global extreme value. Moreover, realization of the algorithm does not need the gradient value of the objective function. For this reason, it is adaptive to searching space. Through the improved artificial fish swarm algorithm, convergence rate and precision are both considerably improved. In aspect of model application, the composite production function model is mainly used to calculate economic growth factor contribution rate. In this article, a relatively more accurate calculating method is proposed. In the end, empirical analysis on economic growth contribution rate of China is implemented.     

Testing homogeneity in semiparametric mixture case–control models

Parametric and semiparametric mixture models have been widely used in applications from many areas, and it is often of interest to test the homogeneity in these models. However, hypothesis testing is non standard due to the fact that several regularity conditions do not hold under the null hypothesis. We consider a semiparametric mixture case–control model, in the sense that the density ratio of two distributions is assumed to be of an exponential form, while the baseline density is unspecified. This model was first considered by Qin and Liang (2011 Qin, J., Liang, K.Y. (2011). Hypothesis testing in a mixture case–control model. Biometrics 67(1):182–198.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], biometrics), and they proposed a modified score statistic for testing homogeneity. In this article, we consider alternative testing procedures based on supremum statistics, which could improve power against certain types of alternatives. We demonstrate the connection and comparison among the proposed and existing approaches. In addition, we provide a unified theoretical justification of the supremum test and other existing test statistics from an empirical likelihood perspective. The finite-sample performance of the supremum test statistics was evaluated in simulation studies.     

浅析和服图案中的自然崇拜

太平洋地震带所带来的天灾,海洋带来的自然恩惠,让大和民族对自然既敬畏又依赖,进而发展出咏诵自然的“物哀”之情,对自然的情感激发了对“现世”的感怀和珍惜,这样的情感反映在他们的服饰文化上,尤其是图案上.他们从邻邦中国引入了汉族的服饰形制,结合本土的自然风物,创造出独特的纹饰图案.     

知识主体的突进与退隐:从笛卡尔到福柯

在西方哲学的知识论传统中,哲学家们倾向于把主体和客体理解为他们各自规范的知识观念所要求的必要功能。在古代哲学家们的思想中,自然和客体知识的可能性问题受到主要讨论,但没有明确地思考主体问题。近现代主体观的兴起所依赖的个体观念只是在后来的基督教思想中才进入哲学传统。以个体观念为先决条件的个体责任的观念已然现身于奥古斯丁的著作中。奥古斯丁对自我的直接诉求,天才般地开启了笛卡尔的"我思"观念的源头。由此形成的笛卡尔的知识主体,是一个抽象的认识论的假定,一个消极的旁观者。康德有限度地追随了笛卡尔的主体观念,但把笛卡尔的作为消极的旁观者的主体改造成了积极的行动者。康德在知识观上的这种"哥白尼式的"革命,构成了随后德国唯心主义主体观的基础。整体上看,康德之后的主体观存在着一种越来越向笛卡尔的主体观和古希腊的主体观隐退的明显倾向,及至海德格尔后期和后结构主义,这种倾向最终导致了向古希腊知识主体的全面回归。

基于制造业转移的长三角地区产业结构优化研究

经济增长发展到一定阶段,必然伴随着产业结构的调整和优化。中国制造业虽大但不强,多数企业尚处于产业链中低附加值的底部。制造业转移,特别是我国如何承接国际制造业转移是值得关注的话题。对于区域而言,制造业转移对于区域产业结构的优化具有促进作用,选择合适的主导产业是长三角地区产业结构优化的重要路径。长三角地区制造业转移促进产业结构优化的实证研究结果表明,制造业的转移对产业结构优化具有较为显著的影响。长三角地区应当在科学发展观的指引下,遵循制造业发展规律和产业结构优化规律,积极推动制造业在不同地区间的转移。
