长三角产业集聚对区域经济一体化的影响研究 ——基于SDM模型

以长三角2003—2018年为样本观测期,运用相关产业集聚指数分别计算产业集聚水平、综合评价法测度长三角区域经济一体化指数;利用社会经济距离矩阵运用空间面板模型,得出产业集聚对区域经济一体化的影响.实证结果表明:①从空间总体效应看:本地区产业协同集聚、生产性服务业集聚、制造业集聚对本地的区域经济一体化水平有正向影响,其中生产性服务业集聚对本地区区域经济一体化的影响最大,生产性服务业协同集聚对本地的区域经济一体化有负向影响.就相邻地区间产业集聚对区域经济一体化的影响而言,产业协同集聚、制造业集聚有负向影响,生产性服务业协同集聚有正向影响.②从空间效应分解看:各产业集聚对区域经济一体化的效应绝对值各有差异.产业协同集聚的间接效应(负向效应)大于直接效应(正向效应)与总效应(负向效应);生产性服务业协同集聚的间接效应(正向效应)大于直接效应(负向效应)与总效应(正向效应);制造业集聚的总效应(负向效应)小于间接效应(负向效应).     

施工企业投标优化的问题与对策

通过对某大型施工企业多个铁路、公路施工项目部的调查，总结了企业当前投标优化方面存在的问题。针对企业以铁路、公路项目为主业的特点，提出了优势项目滚动发展、建立有效激励制度、做好投标准备、优化施工组织设计、应用报价技巧等优化对策。对于施工企业改善市场经营效果，提高中标质量，增加项目盈利有重要的借鉴作用。     

建筑装饰材料课程教学改革探索

在室内外装修中,人们对建筑装饰材料的使用非常重视。在高职院校建筑装饰材料课程的教学中,不仅要培养学生掌握装饰材料的基本理论知识,而且要使学生结合实践,能熟练选择和运用材料。

高校学生纪律处分撤销制度的构建

高校学生纪律处分在实现教育管理目的和保护学生权利方面存在一些问题,应逐步建立和完善纪律处分撤销制度,充分发挥纪律处分的育人功能和价值。现阶段,学生纪律处分撤销制度构建要充分体现处分的公平、公正、关怀原则,实现以人为本的教育理念。     

Points System:An Universal Beneficial System with Multiple Objectives of Reform on Household Registration System

Reform of China's Household Registration system(HRS) has been entering a new stage and deserves us to research.The paper argues that reform of HRS should have multiple objectives.It examines various local efforts and practices of the reform and claims that the point system is one of the most feasible alternative systems for the HRS that can fit those multiple reform objectives.The system could also be treated as the new institutional basic for public welfare provision and rights allocation,and a new governance means for population issues as well in China's transitional period.     

Conditional entropy,entropy density,and strong law of large numbers for generalized controlled tree-indexed Markov chains

In this paper, we first introduces a tree model without degree boundedness restriction namely generalized controlled tree T, which is an extension of some known tree models, such as homogeneous tree model, uniformly bounded degree tree model, controlled tree model, etc. Then some limit properties including strong law of large numbers for generalized controlled tree-indexed non homogeneous Markov chain are obtained. Finally, we establish some entropy density properties, monotonicity of conditional entropy, and entropy properties for generalized controlled tree-indexed Markov chains.     

Uniform Test for Predictive Regression With AR Errors

Testing predictability is of importance in economics and finance. Based on a predictive regression model with independent and identically distributed errors, some uniform tests have been proposed in the literature without distinguishing whether the predicting variable is stationary or nearly integrated. In this article, we extend the empirical likelihood methods of Zhu, Cai, and Peng with independent errors to the case of an AR error process. Again, the proposed new tests do not need to know whether the predicting variable is stationary or nearly integrated, and whether it has a finite variance or an infinite variance. A simulation study shows the new methodologies perform well in finite sample.     

历史理性与历史感

在史学实践的范围内,历史理性可以理解为人们在把握过去时的精神结构和智力装备,历史感是其中不可或缺的要素。对于人事变易无常的意识、对于过去与现在之间的异同的敏锐感受、健全的历史观、开放而自我克制的历史想象力、微观研究与宏观视野的结合,都是历史感在史家史学实践中的具体体现。分析学派的和叙事主义的史学理论都未能将历史感纳入自身的研究焦点。史学理论的当前转向为历史理性和历史感得到更为清晰的理论阐发提供了契机。     

宋代笔记与诗词关系探论

宋代文学的翘楚是文言散文,笔记又属散文中的大宗.梳理宋人笔记与其诗词作品之间的关系,有助于客观全面把握宋人诗文创作、理论批评的特点,避免因局限于一类一体的考察,而忽视对作家的整体性观照.爬梳大量现存宋代笔记和代表性文士的诗词创作情况,探析诗话与词话生成演进的文学史历程,剖判诗词与笔记文类交涉的概貌,可以发现,笔记是诗词作品文本的渊薮,能够据此校勘异文,勾稽本事,作为文献之宝库;更进一步,笔记也与诗词批评专著的生成交涉甚深,诗话、词话的成立,实源于笔记的孳乳,是笔记诞育了这一从著述体式到内容题材都极富中国文学批评特色的典型形式;另外,"以笔记为诗""诗化笔记",彰显出二者文体互渗的审美取径.
