空间计量视角下创新网络结构资本对产业发展的影响测度

针对创新网络结构资本空间溢出如何影响产业发展的问题,基于地理邻近性和社会邻近性动态耦合视角,运用加权平均思想构建动态空间权重矩阵,并借助Moran′s I空间相关性检验、空间滞后（SLM）、空间误差（SEM）和空间杜宾（SDM）模型实验测度多元“地理-社会”邻近耦合下创新网络结构资本对产业发展的影响。以广西电子信息产业专利数据为例展开实证研究发现：①广西电子信息产业发展空间集聚效应明显,且地理邻近性作用大于社会邻近性;②广西电子信息创新网络结构资本空间溢出能够产生产业发展空间集聚效应;③广西电子信息创新网络结构资本通过直接和间接层次路径影响产业发展。研究结论可为产业创新空间（均衡）发展提供决策支持。     

环境成本会计初探

随着科学技术的迅猛发展,人类把发展生产力建立在对自然过度索取的基础上,而补偿普遍不足,迫于各方面的压力,企业不得不履行其保护环境资源的社会责任,因此环境成本必将成为企业成本的重要组成部分。本文旨在对环境成本的概念、确认、计量和报告等进行初步探讨。     

连续波相干应答机的测速定位误差

在高精度的连续波跟踪测量系统中,应答机是其测速定位信号传输通道的重要部分。本文分析了系统本振及应答机中采用的非相干本振的相位噪声所引起的测量误差,推导了测速定位误差的数学表达式。分析表明,非相干本振会使测量产生较大的误差。

关于SPS措施的研究动态综述

SPS措施是与食品安全、动植物健康、环境风险密切相关的技术性措施,也是国际贸易必须遵循的游戏规则,是一把“双刃”剑。西方学者对SPS的研究已形成较为完整和成熟的理论,在研究方法上,多采用定量研究为主,并紧密地服务于贸易实践,这对我国学者加深对SPS的理论认识,借鉴以贸易实践为基础的量化研究方法,具有重要启示。本文从多维角度综述了中外学者关于SPS的研究成果。     

Demand and distribution relationships in the ready-to-drink iced tea market: A graphical approach

The relationship between distribution coverage and market share for an incumbent brand and for new entrants in the ready-to-drink iced tea market during its growth phase is explored using state space diagrams. This graphical visualization method was originally developed to disentangle lead–lag relationships between short nonstationary time series, a situation in which standard econometric methods have difficulty. In this research we show the usefulness of this method for long time series in offering complementary insights to econometric models, in providing a simple and managerially useful tool, and in conducting exploratory data analysis to guide subsequent modeling decisions. In the ready-to-drink iced tea market, usage of this method shows that during introduction of new brands and growth of the category, demand leads distribution, but that as the market matures, the dominant incumbent can defend with a distribution-leading-demand dynamic. Further, distribution coverage eventually becomes relatively stable so that short term fluctuations in demand (probably due to responses to promotion) have minimal impact on distribution.

热敏电阻温度计大范围线性化的新方法

本文提出一种新的对数函数来实现热敏电阻温度计的线性化,介绍所提出的方案的理论研究。文中讨论实现这种对数函数的电路结构,既新颖又简单。所述方案能够在大的动态范围内实现温度—电压变换,而且输出与环境温度的波动无关。电路测试结果证实了理论研究所得出的结论。

长三角协同创新网络韧性演化及驱动机制研究

构建以网络节点韧性、网络结构韧性以及网络群落韧性为核心的城市网络韧性评价体系,并运用ERGM模型分析创新网络韧性形成的驱动机制。研究表明：①创新网络节点韧性分布格局呈动态演进特征,由以“沪宁”为强韧性核心形态向以“沪苏锡”为强韧性核心再向以“沪宁苏杭”为强韧性核心形态转变;②网络结构类型相对稳定,三元结构中以核心节点散射联系的网络结构为主,四元结构中以散射联系及三元结构为基础的网络结构为主,随时间演进,整体网络结构韧性表现为曲折提升趋势;③创新网络群落逐渐减少,聚集指数持续上升,长三角创新一体化程度不断加深,抵御外部冲击能力增强;④创新合作互惠性及交互性逐渐成为创新网络韧性强化的驱动因素,产业结构及对外开放的驱动作用也较为显著,而创新网络韧性与信息距离网络存在强依赖性。     

The customer-based corporate reputation scale: Replication and short form

Corporate reputation attracts significant attention among marketing scholars. However, researchers often overlook customers' opinions specifically. Walsh and Beatty [Walsh, G., Beatty, S.E., Measuring Customer-based Corporate Reputation: Scale Development, Validation, and Application. J Acad Mark Sci 2007; 35(1): 127–143.] identify dimensions of customer-based corporate reputation (CBR); they develop scales to measure these dimensions. Researchers in the present study use the Walsh and Beatty CBR scale in the UK and Germany across contexts to study the cross-cultural validity of the measure of customer-based corporate reputation. This study assesses an abbreviated version of the CBR scale (with 15 items). The CBR Short scale has equally good dimensional properties as the original scale. The paper ends with implications for cross-cultural marketing research and management.
