房地产企业经理人激励机制选择——基于需求层次理论的分析

随着我国工业化和城市化步伐的不断加快,房地产业已成为我国国民经济的主要支柱行业之一。房地产业的特殊性决定了房地产企业经营中对经营者具有强烈的依赖性。本文综述了经理人激励的相关理论和管理理论的主要理论,调查了房地产业企业经理人现有激励状况与激励偏好,并就房地产业企业经理人激励现状和改进做出分析。依据基于马斯洛的需要层次理论的分析,本研究认为,采取“经理人持股”方式,结合其他激励方式,可以有效的满足经理人的主要需求,有利于企业核心竞争力的培育和发展。     

我国产业集群协同创新能力评价综述

产业集群作为区域经济发展体系的重要组成部分,其竞争优势在很大程度上就来自于其创新能力以及集群内部主体间相互交错的协同作用与协同创新.因此,要保持产业集群的先进性和活跃性,研究其协同创新能力具有十分重要的意义.文章分析了产业集群和协同创新的相关研究,对产业集群协同创新的概念、指标选取原则、指标体系和模型进行了综述,并就相关研究进行了评述与展望.     

Microcredit,Labor, and Poverty Impacts in Urban Mexico

Improved household accessibility to credit is a significant determinant of intra‐household allocation of labor resources with important implications for productivity, income, and poverty status. However, credit accessibility could also have wider impacts on poverty if it leads to new hires outside the household. This paper contributes to the existing literature on microcredit in two important ways. First, it investigates the routes through which microcredit reaches those in poverty outside the household. We test whether by lending to the vulnerable non‐poor microcredit can indirectly benefit poor laborers through increased employment. Second, we conduct the study in the context of urban poverty Mexico. This is relevant when considering that labor often represents the only source of livelihoods to the extreme urban poor. Our findings point to significant trickle‐down effects of microcredit that benefit poor laborers; however, these effects are only observed after loan‐supported enterprising households achieve earnings well above the poverty line.

基于拟牛顿法频率域全波形反演研究

全波形反演是综合利用地震波场的运动学和动力学参数,通过最小二乘来拟合实际波场和预测波场,从而获得地质结构和岩性资料的方法。本文先简述了频率域地震波正演,之后利用拟牛顿法来推导频率域全波形反演,克服了高斯——牛顿法中海森矩阵可能奇异或者非正定特性,通过图形对比,得到频率域全波形反演局限在于频率的缺失和来自其它地质结构对三维地质模型受到的影响比较大,合理选择频点和频宽进行反演可解决频率缺失的影响,二维地质模型的反演效果理想,而三维地质模型的反演有待提高和改进。     

企业外部知识搜索能力影响因素研究

外部知识搜索能力成为影响企业开放式创新绩效的关键。通过对企业知识搜索能力影响因素文献的梳理,以整合的思维,从宏观环境层、中观情境层及微观主体层系统归纳了影响外部知识搜索能力的诸因素,分析了各层次因素间的交互效应,构建了企业外部知识搜索能力影响因素模型。     

MIMO-OFDM信道估计新方法

近几年来,无线通信技术正发生着巨大的变化,无线传播的独特功能如反射,折射等,包括多径衰落,路径损耗的结果和多普勒频移,使无线通信具有高速的信息传递功能。此外无线通信信道由于不同的结构,在互联网中由于数据包的损失而引起的网络拥塞已不再只是无线环境下的问题了。OFDM和MIMO两种技术的结合使得多用户在无线信道中传输成为可能,本文通过对比两种不同信道估计技术,改善了无线信道估计的性能。     

浅谈中专毕业护士如何带教本科生护士

新护士让教员带教是临床实习的一个重要环节,是理论联系实际、巩固和提高已学知识的有效途径。众所周知,1998年以前毕业的护士大都是中专毕业,中专毕业的护士如何带教本科生新护士成了我们急需探讨的话题。     

促进我国战略性新兴产业发展的财税政策研究

由于我国战略性新兴产业尚处于初级成长阶段,亟需政府强有力的政策扶持和宏观调控。财税政策作为国家调节经济最重要和最有效的政策工具,无疑是政府首选的"制胜法宝"。发挥财税政策的引导效应和激励作用,有效促进战略性新兴产业的发展壮大,是当前世界各国普遍的做法,也是发达国家取得成功的经验所在。为此,我国亟需抓住全球新科技革命与产业革命的历史机遇,强化财税政策支持力度,加快培育和发展战略性新兴产业。     

Regional allocation of carbon dioxide abatement in China

This paper aims to identify which provinces will be allocated more (less) of a carbon dioxide reduction burden within China's pledge to reduce its carbon intensity at the Copenhagen conference. Using an extended Slacks-Based Measure (SBM) model incorporating an undesirable output, the CO₂ reduction potential and marginal abatement costs are estimated for 29 provinces over the period 1995–2007. The CO₂ Abatement Capacity Index (ACI) is constructed based on weighted equity and efficiency indexes. We find that there exists a large gap in potential reduction capability and marginal abatement cost among the eastern, middle and western regions. The eastern region has the least inefficient emission and the highest marginal abatement cost, while the western region has the largest potential reduction capability and the lowest marginal cost faced in reducing CO₂ emissions. The difference in potential CO₂ abatement among the provinces results from different industry structures, energy compositions and degrees of the openness of trade. The ACI ranking and the final allocation among provinces depend on the policy-makers' preferences regarding equity and efficiency.
