中国公司声誉测量指标构建的实证研究

作为一种特殊的无形资产,公司声誉能够帮助企业有效整合企业内外的资源,但是由于认知的不同,公司声誉在不同的文化体系下有很大的差异.美国的公司声誉研究所通过多年的研究认为,美国人从产品和服务、工作环境、社会责任、愿景和领导、财务绩效、情感吸引等六个因子去衡量公司声誉,并把这六个因子的指标体系称为"誉商","誉商"的指标体系已经在世界许多国家得到了认同.本文首先对美国"誉商"指标在中国的适应性进行了研究,得到了一个五因子的指标体系;然后根据中国企业的现实情况,寻找与中国公司声誉密切相关的补充指标,对中国公司的声誉构成进行了探索,得到了一个七因子的指标体系,并认为社会背景因子和跨国经营能力因子是中国公司声誉的专用因子.     

Scaling unobservable constructs in social science

The use of the logit–probit model for constructing social measurement scales is explored by using two data sets. The first was specifically designed for scaling and consists of answers by 1490 individuals to five questions on economic self-determination. The second is from the Workplace Industrial Relations Survey and relates to answers to six questions addressed to 1005 firms about innovations. It is shown that although scales can be constructed their precision (reliability) is likely to be low. Further, for examples like these, latent class models may give an equally satisfactory account of the data.     

大学生主观生活质量及其影响因素研究

大学生的主观生活质量是目前学术领域研究比较薄弱的一个环节。文章通过实证调查所得资料的分析,认为当今大学生的主观生活质量总体上处于比较理想的水平,并通过因子分析和多元回归等统计方法,发现影响大学生主观生活质量的因素首先是学习满意度,其次包括人际关系满意度、精神满意度等10个方面。性别、家庭经济状况和年级对大学生的主观生活质量也有不同程度的影响。     

Forecasting data revisions of GDP: a mixed frequency approach

Releases of GDP data undergo a series of revisions over time. These revisions have an impact on the results of macroeconometric models documented by the growing literature on real-time data applications. Revisions of U.S. GDP data can be explained and are partly predictable according to Faust et al. (J. Money Credit Bank. 37(3):403–419, 2005) or Fixler and Grimm (J. Product. Anal. 25:213–229, 2006). This analysis proposes the inclusion of mixed frequency data for forecasting GDP revisions. Thereby, the information set available around the first data vintage can be better exploited than the pure quarterly data. In-sample and out-of-sample results suggest that forecasts of GDP revisions can be improved by using mixed frequency data.     

Allocating Capacity with Demand Competition: Fixed Factor Allocation*

We consider a supply chain consisting of a supplier and two retailers. The supplier sells a single product to the retailers, who, in turn, retail the product to customers. The supplier has limited production capacity, and the retailers compete for the supplier's capacity and are duopolists engaged in Cournot competition for their customers. When the sum of the retailers' orders exceeds the supplier's capacity, the supplier allocates his capacity according to a preannounced allocation rule. We propose a new capacity allocation rule, fixed factor allocation, which incorporates the ideas of proportional and lexicographic allocations: it prioritizes retailers as in lexicographic allocation, but guarantees only a fixed proportion of the total available capacity to the prioritized retailer. We show that (1) the fixed factor allocation rule incorporates lexicographic and proportional allocations from the perspectives of the supplier and the supply chain; (2) under fixed factor allocation, the supply chain profit is not affected by the allocation factor when it is greater than a threshold; (3) the retailers share the supply chain profit with the supplier depending on the value of the allocation factor; and (4) the fixed factor allocation coordinates the supply chain when the market size is sufficiently large. We also compare fixed factor with proportional and lexicographic allocations, respectively. Furthermore, we demonstrate how the supplier can optimize his capacity level and wholesale price under fixed factor allocation.     

子女受教育状况在农户非农 外出务工决策中的作用

文章旨在分析农户在非农外出务工决策过程中受子女受教育状况的影响程度。文章利用甘肃基础教育的调查数据，比较了不同类型农户的家庭特征和地区特征，并采用概率模型实证分析了子女受教育状况对农村地区非农外出务工决策的作用。研究结果表明，农户外出务工决策明显受到子女受教育状况的抑制影响，家庭中学龄前儿童、小学生和高中生人数每增加1人，家庭外出务工的概率将分别降低17．89％、3．93％、6．90％。这在一定程度上验证了代际因素在农户家庭决策中的重要作用。     

The derivation of a brief Student Nurse Stress Index

The lack of an adequate measure of perceived sources of stress for student nurses led to the construction of the Student Nurse Stress Index (SNSI). Responses from 235 first-year student nurses to 35 items from the Beck and Srivastava Stress Inventory (Beck, and Srivastava, 1991), and 15 new items, were subjected to exploratory factor analysis using principal components analysis and oblimin rotation. A reliable 22-variable solution with a simple oblique structure including Academic load, Clinical sources, Interface worries, and Personal problems factors was obtained in this initial sample, and confirmed at an exploratory level in a further independent validation sample of 188 first-year students. Confirmatory factor analysis established the four-factor model in the first sample, but required that three variables load onto more than one factor. This more complex four-factor model was confirmed using independent data from the validation sample, and the total invariance of factor loadings and factor covariances of this more complex four-factor model was established in both data sets simultaneously using multi-sample techniques. The SNSI shows cross-sample factor congruence, good internal reliabilities, and concurrent and discriminant validity across a range of reporting conditions.     

中国地区经济发展不平衡及影响因素研究——基于夜间灯光数据

本文以全球夜间灯光数据为参照，分别从地级和县级行政区层面研究了1992-2016年我国地区经济发展不平衡的演化及其影响因素。受地级和县级人均GDP数据可得性和准确性的限制，首先利用省级人均GDP与灯光亮度关系估算地级和县级的经济产出水平。基于地级和县级经济产出水平，测算了地区经济差异指数、泰尔指数和阿特金森指数，证实了各省份、全国及四大地区均呈现库兹涅茨倒“U”曲线。对泰尔指数进行四大地区分解，发现了四大地区间的经济差异是我国地区经济不平衡的主要根源。地区经济发展不平衡的影响因素研究再次证实库兹涅茨曲线的存在，还发现城镇化水平和产业结构变迁与地区经济不平衡之间也存在倒“U”型关系，教育水平的提升与交通基础设施的完善分别扩大和缩小了地区经济的不平衡，但资源禀赋、对外开放度和政府消费与地区经济不平衡的关系并不显著。
