关于推进企业信用体系建设的思考

加快建立和完善企业信用体系,是解决我国目前企业信用危机的重要措施。文章对现今我国企业信用缺失现象造成的危害及产生的原因进行了简要分析,提出了有一定价值的对策。     

我国各地区高技术产业投入产出效率综合评价

根据我国30个省(市/区)2007年高技术产业的相关投入产出数据指标,基于因子分析和数据包络分析(DEA)方法,对比分析了各个地区的高技术产业的投入产出技术效率、投入产出比例。分析结果表明,东部地区在高技术产业的投入产出数量上占有绝对优势,但是投入存在着大量冗余,而中西部地区的投入产出数量相对不足。因此,应当调整我国高技术产业的区域投入结构,加强东部地区与中西部地区的高技术产业在技术、资金、人才上的融合。     

关系嵌入、知识获取与BOP市场导向的产品创新：内外部不确定性的调节作用

在主流市场日趋饱和的背景下,更多企业将目光聚焦于金字塔底层市场。基于权变视角,探索企业在BOP跨部门合作网络中,双边关系耦合与网络嵌入交互构建的双环协同机制如何影响企业外部知识攫取,进而作用于BOP市场导向的产品创新。采用大样本问卷调查,收集396家电动自行车企业数据,利用多元回归分析对研究假设进行实证检验。研究表明,跨层级嵌入双环协同机制与知识获取呈倒U型关系,高外部不确定性会增强该倒U型关系,但高内部不确定性对该倒U型关系无显著影响;通过知识获取的部分中介传导效应,最终跨层级嵌入双环协同与BOP产品创新呈倒U型关系。结论对企业把控BOP网络嵌入程度、优化网络配置及网络治理具有一定指导意义。     

Analysis of interregional industry linkage and economic distance in China: evidence from the mining industry

The mining industry is an important sector of the national economy, which provides essential support for energy and other resources for economic development. Industrial linkage and economic distance are two different concepts in measuring the correlationship of different industries, in this article, we apply the model that combines both of them to analyse the industries significantly influence the mining industry. We find that electricity and heating industry, and the mining industry itself from forward linkages have greatly influenced the mining industry, and the industries from backward linkages affect mining industry are changing with industrial economic transformation. We also find resources can flow across several regions only after 2007, which means the role of geographical factors limiting long-range transportation of resources is weakening after 2007. And we explain how resources flow among various regions during 1997 ~ 2007. Based on the findings above, policy implications from the empirical results obtained are discussed.     

Financial liberalization and sectoral reallocation of capital in South Africa

We examine the impact of financial reforms on efficient reallocation of capital within and between sectors in South Africa using firm-level panel data for the period 1991–2008. The measure of efficient allocation of capital is based on the Tobin’s Q. We find that financial reforms are associated with improvements in within-sector, but not between-sector allocation of capital. These results imply that for South Africa to unleash the potential for take-off that is often associated with reallocation of resources from the primitive to modern sectors, reforms that focus beyond the financial sector are necessary. While more research is necessary to determine what would fully constitute such additional reforms, our analysis shows that reforms that improve the quality of economic institutions may be a step in the right the direction.     

冀北超基性岩地质特征

冀北超基性岩带位于华北地台北缘，受崇礼－隆化深大断裂控制。该岩带从西往东可分为赤城、丰宁－滦平和承德－平泉三个超基性岩群。各岩群的形态、产状、岩石类型、矿物成份、化学成份各有特点，表现出一定的规律性。Ｋ－Ａｒ及Ｓｍ－Ｎｄ同位素年龄表明，这些超基性告形成于中元古宙、海西期及印支期。

排球中的物理问题:有目的的扣球

排球教练向作者提出了一个排球中的物理问题:“运动员应跳多高去扣球才能使球过网并落在对方场地预想的区域内?”作者在本文中应用抛物体的运动公式及有关的力学知识推导证明这个问题,并获得了当球落在对方场地的预想区域时,运动员跳起扣球的高度公式.     

Customer query handling in sales interactions

Using a novel approach with video-recordings of sales interactions, this study focuses on a dynamic analysis of salesperson effectiveness in handling customer queries. We conceptualize salesperson behaviors, namely, resolving, relating, and emoting, as separate elements of customer query handling and empirically identify the distinct verbal and nonverbal cues that salespeople use to display these behaviors during sales interactions. We draw from compensation effects in social cognition theory to propose that customers’ perceptions of a salesperson’s effectiveness are prone to trade-offs between competence (resolving behaviors) and warmth (relating and emoting behaviors). Results, robust to endogeneity corrections, support the proposed tradeoffs such that the effectiveness of salesperson’s resolving behavior is significantly curtailed, even neutralized, by the salesperson’s relating and emoting behaviors. We situate these counterintuitive results within the extant theory and research on sales interactions, and outline implications for practice.
