解析经理股票期权制度

盛行于西方国家的经理股票期权制度（简称ESO），近两年来已逐渐引起中国有关方面的注意，学者和企业家们从不同角度出发，就中国实行经理股票期权的可行性及其现实意义进行了探讨和研究。本文试图从股票期权制度的产生、包含要素和效应等方面进行介绍并就其在中国的运用现状及发展作一些粗浅的探讨。     

Untangling the relationships between consumer characteristics,shopping values,and behavioral intention in online group buying

This study examines the link among consumer characteristics (price-sensitive behavior, variety-seeking behavior, and compulsive buying behavior), shopping values (utilitarian and hedonic shopping values), and behavioral intention in online group buying (OGB). This study tests usable responses collected by means of mall-intercept systematic sampling from consumers who previously participated in OGB. Structural equation modeling was used to analyze data and test the hypothesized relationships. Findings suggest that price-sensitive and variety-seeking behaviors are significantly related to utilitarian shopping value, whereas price-sensitive, variety-seeking, and compulsive buying behaviors are significantly related to hedonic shopping value. Both utilitarian and hedonic shopping values significantly influence consumers’ OGB intentions. For a successful OGB strategy, Internet marketers and site operators should emphasize the utilitarian shopping value of price saving and selection and introduce the hedonic shopping values of promotions and sensory experiences. This study provides a link between two streams of prior research – that is, consumer characteristics and shopping values. Furthermore, it validates an empirical model whose results can help business practitioners make better-informed marketing management decisions for OGB and help academics and consumers better understand OGB behavior.     

精准扶贫政策对贫困户增收效应的科学评估

在后扶贫时代到来之际,有必要科学评估精准扶贫政策对贫困户的增收效应,探讨增收机制,从而为后续的防返贫工作提供指导.利用2018年实地调查的微观数据研究发现:建档立卡政策的确能够有效提高贫困户的家庭收入.无论是建档立卡政策还是贫困村政策,其最终的落脚点均在于开发式扶贫.在增强贫困户内生动力上,产业扶贫、金融扶贫以及就业扶贫均产生了正向作用,首先为产业扶贫,其次为金融扶贫,最后为就业扶贫.自2020年后,在乡村振兴战略框架下,要有效融合产业扶贫、金融扶贫与就业扶贫,努力保证在脱贫攻坚过程中培育起来的扶贫体系实现可持续发展.     

石化电厂锅炉结渣及煤种优化试验

煤种及煤质对锅炉运行的经济性和安全性有较大影响。根据石化电厂410t／h锅炉的特点，对煤源进行了跟踪分析，并对单煤和混煤的实验室燃烧特性进行了研究。据此对试验煤种的燃烧特性进行了排序，，并提出了相应的混配方案，为石化电厂煤炭采购、混配以及合理使用提供了依据。

Finding Bayesian Optimal Designs for Nonlinear Models: A Semidefinite Programming‐Based Approach

This paper uses semidefinite programming (SDP) to construct Bayesian optimal design for nonlinear regression models. The setup here extends the formulation of the optimal designs problem as an SDP problem from linear to nonlinear models. Gaussian quadrature formulas (GQF) are used to compute the expectation in the Bayesian design criterion, such as D‐, A‐ or E‐optimality. As an illustrative example, we demonstrate the approach using the power‐logistic model and compare results in the literature. Additionally, we investigate how the optimal design is impacted by different discretising schemes for the design space, different amounts of uncertainty in the parameter values, different choices of GQF and different prior distributions for the vector of model parameters, including normal priors with and without correlated components. Further applications to find Bayesian D‐optimal designs with two regressors for a logistic model and a two‐variable generalised linear model with a gamma distributed response are discussed, and some limitations of our approach are noted.     

Huatie Intermedia, A Leading Media Runner in Low Voice Train

When most of the media are confused in the anxiety of the advertisements income in 2007, Lu Liming has started the consideration of seeking the breakthrough of railway media in 2008. Actually Lu has some anxiety, for instance, the too much scheduled advertisements to be reasonably arranged.     

我国通胀持久性的区间转换分析及其政策启示

抗通胀是当前一个阶段我国经济面临的重要难题。本文通过非线性小波变换阀值去噪和双区间Markov转移模型的分析表明,无论高通胀区还是低通胀区,我国通货膨胀的持久性均在0.9以上,通胀率偏离预期后受到随机冲击所需的回复时间较长,通货膨胀的治理成本较高。为有效降低我国通胀的高持久性,提高央行货币政策制定的透明度和政策施行的信用度是首要解决的问题。     

软土地基中新型CFG桩板结构数值模拟研究

新型CFG桩板结构复合地基是在CFG桩复合地基和桩板结构复合地基的基础上提出的一种地基处理方法,其借鉴桩-承台-土相互作用理论,充分利用承载板"荷载分配"作用以及桩间土的承载和变形协调能力。以京沪高铁某段软土地基为工程背景,通过有限元数值方法对常规CFG桩复合地基和新型CFG桩板结构复合地基的控制沉降效果进行对比分析,讨论桩板结构形式对复合地基沉降特性的影响,对新型CFG桩板结构复合地基数值模拟给出若干结论。     

Ownership,autonomy, incentives and efficiency: Evidence from the forest product processing industry in China

Using enterprise-level data from China's Northeast-Inner Mongolia state-owned forest area for the year 2004, this paper investigates the technical efficiency of forest product processing mills and the relationship between institutional and managerial practices and efficiency. A two-stage procedure proposed by Simar and Wilson (2007) is adopted. In the first stage, a bootstrapped data envelopment analysis (DEA) model is used to compute the efficiency scores. In the second stage, the bootstrapped DEA scores are estimated over a set of mills’ institutional and managerial systems and other characteristics with a bootstrapped truncated regression. The results show that there is a wide dispersion in the technical efficiency among mills. Private ownership, autonomy and mill size have statistically significant positive impacts on efficiency. These results provide support for the ongoing reform and implications for future development of this area.
