技术进步对产业增长作用的测度——基于北京高技术产业的实证研究

在分析技术进步对产业增长作用的传统理论和方法的基础上,将技术进步导致的规模效应置于技术进步效应中,并把技术进步效应分解为技术进步的纯产出效应和规模效应。构建了修正的DEA-Malmquist指数模型,基于1998—2008年全国22个地区高技术产业五大行业的面板数据,对北京高技术产业进行了实证分析,得出了北京高技术产业及五大行业的技术进步效应值及其分解值,验证了本文提出的理论和方法的科学合理性。     

Efficiency and productivity of the food and beverage listed firms in the pre-recession and recessionary periods in Greece

This study uses data envelopment analysis to examine the liquidity and sales efficiency of the Food and Beverage listed firms in Athens Exchange in the period 2006–2012. The liquidity efficiency of the firms is higher than the sales efficiency but the results indicate that there are not statistical significant differences in the rankings estimated by the two models in each period. The Malmquist Productivity Index reveals that over the period of the study, firms have experienced an annual average increase in productivity of 0.5% (a slight progress). On examining the components of this productivity change, it becomes evident that firms have experienced an annual average of 2% increase in technology combined with a decrease in technical efficiency of –1.5%. The results indicate that 52.4% of the firms experienced productivity gains in the examined period, and this was mainly the result of technological gain rather than efficiency improvement. More than 90% of the firms in the sample shift the efficiency frontier and only 33.3% of the firms are catching up, improving their productivity by reducing inefficiency. Moreover, the empirical study reveals that the overall technical inefficiencies of the firms are primarily caused by pure technical inefficiencies rather than scale inefficiencies.     

服务消费的满意度、感知价值与消费忠诚——医疗领域的一个实证研究

本文以济南某三甲医院的263名医疗服务消费者(患者)为样本,对服务消费者的满意度、感知价值和消费忠诚之间的关系进行了实证研究。结果表明,满意度是感知价值影响消费忠诚的中介变量,感知价值是消费忠诚的最终来源。其应用意义在于,在医院管理中,不能仅停留于对患者满意度的测评,应在功能、情感、社会3个方面为患者提供高水平的服务。

Hedging Housing Risk in London

This paper investigates the benefits of allowing households to compensate the portfolio distortion due to their housing consumption through investments in housing price derivatives. Focusing on the London market, we show that a major loss from over-investment in housing is that households are forced to hold a very risky portfolio. However, the strong performance of the London housing market means that little is lost in terms of expected returns. Even households with limited wealth are better off owning their home rather than renting and investing in financial assets, as long as they are willing to face the financial risk involved. In this context, access to housing price derivatives would benefit most poor homeowners looking to limit their risk exposure. It would also benefit wealthier investors looking for the high returns provided by housing investments without the costs of direct ownership of properties. Comparisons with French, Swedish and U.S. data provide a broader perspective on our findings.     

布伦特原油价格与美元指数的交互相关性分析

以北海布伦特原油的现货价格和美元指数为研究对象,探讨它们之间的交互相关关系。首先运用交互相关统计量定性地说明布伦特原油价格和美元指数之间存在交互相关关系。然后利用多重分形分析法对它们之间的交互相关性作定量的分析,证实了它们之间的交互相关性具有多重分形特征。同时运用MF-DFA方法对单个研究对象进行自相关分析。     

领先顾客的消费者创新性对新能源汽车采用意愿的影响

将领先顾客的消费者创新性分为3个维度——一般创新性、特定创新性和替代创新性。界定了3个维度的具体内涵,并将参照群体示范效应作为消费者创新性的3个维度与新能源汽车采用意愿之间的调节变量。结合技术接受模型,从内外部动机的视角研究消费者创新性对新能源汽车采用意愿的影响机制。在此基础上,构建新能源汽车采用意愿的结构方程模型,对研究假设进行验证。实证结果显示:消费者创新性的3个维度以及感知有用性、感知风险对新能源汽车采用意愿具有不同程度的显著影响;参照群体示范效应有显著的调节作用;感知易用性对新能源汽车采用意愿的影响不显著。     

我国海峡两岸农产品产业内贸易的实证分析

本文选取2001—2006年我国海峡两岸农产品贸易数据,利用G-L指数和B指数从整体和分类两个层面对我国海峡两岸间农产品的产业内贸易状况进行了实证分析,并得出以下结论：我国海峡两岸农产品以产业间贸易为主,产业内贸易水平较低,且在贸易结构上具有较明显的互补性;2001—2006年我国海峡两岸间的贸易变动主要由产业间贸易引起。在此基础上,提出今后两岸农产品产业内贸易的发展方向。     

黑龙江省农业现代化评价

客观评价现代农业发展水平,是制定区域现代农业发展政策与推进“三农”工作的重要前提。该 文基于现代农业特征构建农业现代化评价指标体系,并依此评价黑龙江省农业现代水平的时空特征,主要 结论如下:黑龙江省现代农业于2010年由起步阶段进入了初步实现阶段;全省农业现代化水平的区域差异 明显,以省会哈尔滨为最高值区,整体呈现出由西南向东北的递减趋势;不同地区在现代农业发展中具有 不同的限制因素和主要矛盾;今后,应进一步针对全省及各区域现代农业发展的“瓶颈”环节制定区域农 业发展政策,促进全省现代农业协调、快速和可持续发展。
