福建省高端装备制造业技术创新效率评价

将技术创新分为两个阶段——投入转化阶段和转化产出阶段,运用DEA两阶段法和DEAMalmquist指数法,对2008—2012年福建省高端装备制造业5个细分行业的两阶段技术创新效率进行了静态和动态评价。研究结果如下:在技术创新的第一阶段,福建省高端装备制造业的投入转化效率在很大程度上依赖于技术进步,但这种趋势在减弱;在技术创新的第二阶段,福建省高端装备制造业的转化产出效率呈下降趋势,且技术进步和技术效率对之共同发挥影响作用。     

论西部民族地区自我发展能力的提升

提升西部民族地区自我发展能力,面临着自然环境、经济、政治和思想文化等诸多因素的制约。因此,必须要调整产业结构,完善基础设施建设,增强区域的资本积累能力和要素聚集能力;完善制度,改善环境,增强区域的政府组织协调能力和人文发展能力：构建社会主义核心价值体系,增强区域的民族凝聚力和向心力;创新科技,发展教育,增强区域的智力支持力和发展持续力;合理利用资源,保护环境,增强区域的生态平衡发展能力。     

多市场接触与市场竞争行为——以中国民航运输业为例

多市场接触竞争理论考虑了同一企业在不同市场的竞争行为的关联性,大量来自西方市场的研究证明多市场接触可导致企业在竞争中"相互容忍",降低市场竞争的激烈程度.参照这些研究方法,本文运用中国国内主要定期航线市场数据,计算出航线多市场接触指数,并进行回归分析.结果显示,尽管中国国内航线市场多市场接触程度较高,但对市场竞争的实际影响微弱.研究还发现管制制度是影响中国航空公司竞争战略的重要因素.

企业规模对绩效评价的影响及解决方案

在对同类型企业进行绩效评价时,经常因企业规模不同,导致无法用统一的考核指标得出公平的评价结果。文章以笔者所在的邮政企业为例,运用国资委提出的经营难度系数,对初步考核结果进行差异调节,提出了有效的解决方案。     

The Essential Role of Sense of Community in a Youth Sport Program

This multiphased study identifies the salient benefits that parents seek for their families from a youth sport program. Phase 1, a preseason focus group study of parents of swimmers in three clubs (N = 15), indicated parents seek a sense of community for their children and themselves, and sense of community is linked to their desire for children to learn sport and life skills. Phase 2, a postseason survey of parents in the same three clubs (N = 129), tested the relationships among coaching quality, friendships, organizational communication, sport and life skills, sense of community, parents' satisfaction, and their repeat purchase intention. Using path analysis, sense of community was identified as the key driver of satisfaction and repeat purchase intention, with swimming improvement also having a significant effect on satisfaction. These findings highlight the central role sense of community plays for participants and their families in youth sport contexts.     

“Speculative Influence Network” during financial bubbles: application to Chinese stock markets

We introduce the Speculative Influence Network (SIN) to decipher the causal relationships between sectors (and/or firms) during financial bubbles. The SIN is constructed in two steps. First, we develop a Hidden Markov Model (HMM) of regime-switching between a normal market phase represented by a geometric Brownian motion and a bubble regime represented by the stochastic super-exponential Sornette and Andersen (Int J Mod Phys C 13(2):171–188, 2002) bubble model. The calibration of the HMM provides the probability at each time for a given security to be in the bubble regime. Conditional on two assets being qualified in the bubble regime, we then use the transfer entropy to quantify the influence of the returns of one asset i onto another asset j, from which we introduce the adjacency matrix of the SIN among securities. We apply our technology to the Chinese stock market during the period 2005–2008, during which a normal phase was followed by a spectacular bubble ending in a massive correction. We introduce the Net Speculative Influence Intensity variable as the difference between the transfer entropies from i to j and from j to i, which is used in a series of rank ordered regressions to predict the maximum loss (%MaxLoss) endured during the crash. The sectors that influenced other sectors the most are found to have the largest losses. There is some predictability obtained by using the transfer entropy involving industrial sectors to explain the %MaxLoss of financial institutions but not vice versa. We also show that the bubble state variable calibrated on the Chinese market data corresponds well to the regimes when the market exhibits a strong price acceleration followed by clear change of price regimes. Our results suggest that SIN may contribute significant skill to the development of general linkage-based systemic risks measures and early warning metrics.
