用数学函数分析法对统计指数因素分析的进一步改良——谈综合指数体系的缺陷与消除

指数因素分析法是一种重要的统计分析方法,而其分析结果的正确与否取决于所用的指数体系。利用传统的综合指数体系从事因素分析虽方便,使用,但也存在一些不足。本文提出用其他指数体系进行因素分析的思想,以弥补传统综合指数体系在因素分析中的缺陷。     

基于层次分析法与模糊评价的学科水平评估

在学科建设中,学科水平评估可以采用专家咨询的方法,分别从学术队伍、科学研究、教学与人才培养和工作条件四个方面设计学科水平评估指标体系,运用层次分析法确定指标权重系数,针对评估指标的模糊性,建立学科水平评估模糊综合评价模型,并通过实例分析和计算,证明该学科水平评估体系合理、有效、可行。     

CCI与中国证券市场走势的实证分析

美英等国的消费者信心指数(CCI)对股市指数收益有很重要的影响力。为探讨CCI与中国证券市场走势的相关关系,通过两类模型对1999年10月~2004年8月间我国股市收益与CCI之间的关系进行了实证分析。结果表明:CCI对深沪五个指数的走势有显著的解释与预测效果,但对我国的B股市场似乎没有显著性。

Dimensions of occupational inequality and Duncan's socioeconomic index

Using the original 1962 Blau and Duncan data for white males, I compare relative amounts of inequality in the distributions of occupational prestige, earnings, autonomy, and job skills. Also assessed are the degree of status rigidity (or intercorrelations) among these four dimensions of occupational inequality and the simultaneous relations among these four dimensions in a father-to-son occupational mobility model. These findings are compared to those obtained with Duncan's socioeconomic index to determine whether additional information can be obtained when using independent measures representing the multiple dimensions of occupational inequality versus using the SEI alone. Only minor discrepancies are found, and these relate to autonomy and earnings.An earlier version of this paper was presented at the 1985 Pacific Sociological Association meetings.     

Beggars can be choosers: Resource scarcity,dynamism, search activities,and their joint impact on performance

Research on firm search stresses the need for firms to adapt and align concurrently with their environment to optimize the ability to sense and seize opportunities for sustained performance. We postulate resource scarcity as an important contingency factor for the search-performance relationship, and assess its joint influence with high and low dynamism. Using a dataset spanning 23 years, we examine the performance implications of combinations of internal and external exploratory and exploitative search in resource-scarce environments, under conditions of high and low dynamism. We find that resource scarcity is an important condition for performance stemming from exploratory and exploitative search: even under conditions that involve low dynamism, but joined with resource scarcity, firms may benefit from pursuing exploratory and exploitative knowledge simultaneously.     

How can David orchestrate resources to enhance firm performance? A dynamic approach to coping with resource constraints

Given that the possession of abundant resources does not always guarantee superior firm performance, this study proposes a dynamic approach to enhancing firm value. Building on the resource orchestration thesis, we investigate how firms facing resource constraints enhance their capabilities over time by orchestrating resources and how this resource orchestration can play a role in improving firm performance. Using the dynamic perspective, this study identifies four resource orchestration modes, which are specified based on how a given firm dynamically allocates its resources to technology (enacted by R&D activities) and marketing (enacted by advertising activities). Accordingly, we claim that firms with resource constraints can enhance their performance by escalating or altering their resources over time. To test our hypotheses, we used a sample of 4078 small and medium-sized enterprises in manufacturing industries between 1984 and 2018. We found that focus escalation for technology positively affects firm performance, captured by Tobin's q, and that focus alternation toward either technology or market is positively related to firm performance. Finally, we discuss the theoretical and practical implications of our findings.     

基于成本核算的政府绩效评价指标体系构建与应用

政府绩效评价是政府评价主体运用一定的评价方法对政府绩效进行考核评价的过程。由于我国政府绩效评价起步较晚,部分地方还存在重投入轻管理、重支出轻绩效的问题,绩效考核结果的导向作用不强,成本核算成为提升政府绩效的核心。因此,文章在成本核算的基础上对政府绩效进行评价,采用层次分析法从经济发展、社会管理、教育科技、资源环境、成本管理、公共服务六大方面构建基于成本核算的政府绩效评价指标体系,将其应用于H市政府的绩效评价工作,从而有效地提高政府的公信力和执行力,同时也有助于推进我国政府绩效评价工作的发展。     

双元学习关系、平衡及绩效研究综述

双元学习作为企业获取和创新知识的一种有效方式,是提升企业竞争能力、促进企业可持续发展的关键。通过回顾国内外学者对双元学习的研究,从双元学习的内涵与关系、双元学习平衡的实现方式及其影响因素、双元学习的绩效效果四个方面进行了综述,认为现有研究在研究的层次、维度、视角和方法等方面有待进一步拓展和深入。未来应开展多层次与跨层次的双元学习研究,加强不同理论视角的结合,整合各领域相关研究成果,进一步揭示双元学习内涵与关系的独特性;重视从动态研究视角,深挖影响双元学习平衡的不同层面各因素间的相互关系及其作用机制,提高对情境因素的重视程度,进一步探讨双元学习平衡的实现路径;拓展组织绩效维度,开展双元学习影响组织绩效的权变因素研究,剖析不同条件下双元学习对不同绩效影响的差异。     

以任务为中心：县域编制资源的整体性调配机制研究

在机构编制资源总量控制的前提下,如何通过内部调配,盘活编制资源存量,提升编制资源使用效益,实现编制资源统筹调配和动态调整,是当前机构编制管理改革的重要方向。调研发现,浙江S县创新推出一条“摸清底数-绩效评估-统筹优化”的系统性编制管理改革路径,有效破解编制管理部门多样化、管理流程割裂化、编制利益私有化等多重困境,并通过编制管理的部门协同、流程闭环以及统筹优化实现编制资源的整体性调配。相较于传统以职责划分为基础的科层体制造成的政府碎片化,这种整体性调配以问题为导向,以治理任务为中心重新构建治理场景,能够在场景内部系统实现协调、整合与责任等整体性治理要求,是破解政府碎片化的有效探索。
