我创新因为我是主人翁:心理所有权对创新行为影响机制的被调节中介研究

以华南地区40个制造型企业的529名员工为样本,通过构建被调节的中介模型,分析心理所有权对创新行为的影响以及该影响的具体作用机理。研究发现:心理所有权对创新行为存在显著正向影响;义务感知在心理所有权对创新行为的影响过程中具有显著中介作用;工作压力在义务感知对创新行为的影响过程中具有显著负向调节作用;工作压力对整个中介模型具有显著负向调节作用。     

Implementing high performance HR practices in Asia: HR practice consistency,employee roles,and performance

High performance HR (human resources) practices are well understood to positively impact employee behavior and performance. However, much is still not known about the implementation of effective HR practices and their specific impact on employee behaviors. In this regard, this study identifies the significance of HR practice consistency, develops direct measures of that consistency, and examines the impact on employee role performance. This study also explores how consistency affects shared perceptions of procedural justice and employees’ role performance by employing a cross-level research design. The data in the study were collected from 355 employees of 42 companies within the manufacturing and service industries in Taiwan. This study makes theoretical and methodological contributions by identifying the significance of HR practice consistency, and provides empirical evidences for its potential influences. It also offers practical suggestions that can be used as important reference points by organizations, particularly those in Asia seeking to implement high performance HR practices.     

公共基础设施服务水平主客观测度与发展策略研究——基于16个特大城市的实证分析

以我国16个特大城市为例,对城市公共基础设施服务水平主客观测度的相关性和差异性进行了解析。首先,基于熵值法进行客观测度,结果表明各个城市间公共基础设施服务水平发展不平衡,呈现东部城市优于中西部城市、高行政级别城市优于低行政级别城市、城市群内核心城市优于非核心城市等特点。然后,通过与主观测度的公众满意度进行比较,发现在整体和分系统层面主客观测度之间相关性均不显著;依据主客观测度结果将各个城市归纳为4种类型,并对主客观测度进行差异解析,提出总体上两者之间存在相关而非决定关系,且在维度和效用两方面存在差异。最后,提出提高我国特大城市公共基础设施服务水平的发展策略建议。     

中国国内价值链是怎样形成的？

本文基于区域间投入产出模型进行区域增加值分解,通过构建国内价值链广度、国内价值链深度、国内价值链匹配度等指标,实证研究发现20世纪90年代中期以来中国重化工部门的国内价值链广度高于轻工部门,但同时呈现出下降的趋势。各部门的国内价值链深度逐年提升,其中,内资主导及市场导向型外资推动的国内价值链深度相对更高,而成本导向型外资为主的国内价值链深度较低。各部门的国内价值链匹配度渐趋合理,但仍存在很大程度的资源配置扭曲。     

丝绸之路经济带投资结构对产业结构调整的空间效应——以国内段为例

本文运用全国与丝绸之路经济带沿线9省区市2003～2014年的面板数据,通过建立空间计量模型,分析了投资结构对产业结构变动的空间效应。结果表明：（1）区域产业结构的变动存在显著的空间依赖性;（2）与全国比较,丝绸之路经济带投资结构对产业结构的调整具有显著的促进作用。非公共基础设施投资对产业结构合理化、高级化的积极作用最大,尤其是对西北地区产业结构合理化,西南地区高级化的作用较大,而对全国呈现出消极效应;（3）硬性基础设施投资对西北地区产业结构合理化和高级化的积极作用最明显,而软性基础设施投资对西南地区产业高级化的贡献较大。表明调整丝绸之路经济带投资结构能够提高本地和相邻地区产业结构的优化升级。     

Does High Stock Price Synchronicity Always Hurt Mutual Fund Industry? Sentiment Matters

Investors have agreed that high synchronicity of stock returns adversely influences professional funds' profitability. However, different market conditions where high synchronicity exists may have different effects on this relationship. This study incorporates aggregate investor sentiment as a market condition in the equation to explore whether and when the negative association between synchronicity and fund performance holds. The authors use a sample of actively managed U.S. equity mutual funds from 2000 to 2014 and employ a portfolio of 11 passively managed funds as the benchmark to measure fund performance and fund management skill. They find empirical evidence that synchronicity negatively impacts mutual funds' profitability when the investor sentiment is low. This negative relationship disappears in high-sentiment periods. They also find that in both low- and high-sentiment states, fund managers with superior stock selection skill make more profits from high synchronicity than the average.

政府扶持物流发展的几个博弈问题

中国加入WTO,物流产业面临着前所未有的机遇和挑战,政府和企业所要进行的工作任重道远。我国物流现状远远落后于发达国家,政府作为国家重要基础设施的掌控者和国家宏观经济调控的决策者,应加大力度从宏观和微观的角度支持物流产业的发展,对相关扶持进行博弈决策。     

一种基于路径目的节点数的改进蚁群算法

组播技术是无线Mesh网的关键技术之一,它可以大大提高信息的传播效率。介绍了信息组播的主要步骤,指出蚁群算法是构建路由组播树的高效启发式算法。对传统的蚁群算法进行定性分析,并对其进行改进,在计算路径费用以及信息素更新时考虑路径上的目的节点个数,路径上的目的节点数越多,其信息素增长速率越快。两个例子的仿真结果表明,该改进算法与传统蚁群算法相比分别使费用和代价减少了28.57%和22.36%,改善了系统性能。
