The conventional framework for cross-sectional studies of industrial organisation focuses on the hypothesised relations among structure, conduct and performance (SCP). This paper investigates these relationships for the food and beverage manufacturing industries in a European country, i.e., Greece. 3SLS method is used to estimate the parameters of the profitability, concentration and advertising model for a sample of 38 four-digit industries in 1994. The main results, which are in line with the relevant empirical work, show that profitability is determined by advertising, which, in turn, is affected by both profitability and concentration, while the latter is determined by economies of scale. 相似文献

中国农产品出口市场结构的实证分析及国际比较 总被引:3,自引:0,他引:3
使用了出口市场集中度指数等分析工具,对我国农产品出口市场结构进行实证分析.结果表明,与世界主要农产品出口国相比,我国农产品的出口市场结构比较集中,在1993~2006年期间经历了先恶化后改善的过程;与肉类产品和水产品相比,我国蔬菜水果产品的出口市场结构相对较为合理. 相似文献

A sample of 9339 subjects aged 13–75, living in the six macro-regions of Poland rated the preferences of 140 various food products, eating frequency and factors influencing food choice. Four groups of consumers were found: “consumers susceptible to advertising and seeking novel healthy products” (33.2% of the sample), “consumers not taking care of their health” (25.4%), “consumers not susceptible to advertising and taking care of their health” (32.5%), and “consumers insensitive to sensory attributes of fruit and vegetables” (9.0%). Among factors influencing the food choice, sensory and functional factors were significant, and health and price – moderate. Advertising was generally denied as an important factor in food choice. The food choice motives were highly dependent on age and gender, and to a lower extent – on region of residence, size of place of residence, economic condition and education level. Women/girls more often showed pro-health behaviours in food choice, choice motives, preferences and food intake. 相似文献

This study measures the incidence and tolerance of sexual harassment in hospitality in an effort to understand its causes. It examines the tradition of sexual behaviour in hospitality, exacerbated by hierarchical structures, the nature of hospitality work, the characteristics of typical front line workers, customers’ reduced sense of responsibility, and an emphasis on meeting customers’ needs. Customer contact is shown to be a key predictor of harassment, especially for young European women. The typical profiles of hospitality staff and the nature and traditions of the industry are considered important causes of harassment in hospitality. 相似文献

给出了一种采用信干噪比准则的、集成了预多波束天线与LMS自适应天线的软件天线方案,该方案采用开关合并方法,把软件天线输出接到最大输出信噪比的算法输出,实现算法分集.在TD-SCDMA动态模型上对提出的方法进行了仿真,结果表明,采用集成软件天线方案的误码率性能要优于单纯的预多波束天线或LMS自适应智能天线.仿真过程考虑了用户来波方向和用户到基站距离的动态变化,以及功率控制算法和系统同步过程的影响. 相似文献

笔者基于山东省693个样本数据,以绿色食品为例,将消费者认知行为划分为知晓、识别与使用三个层面,构建多变量Probit模型,分析在消费者认知程度提高过程中起主要作用的因素。研究发现,男性或年轻受访者在知晓层面的认知率较高,而女性、年长受访者在识别和使用层面的认知率相对较高;收入和卷入程度的影响在知晓层面不显著,而在识别和使用层面显著;学历、子女状况与环境保护意识的影响在各层面皆显著;食品安全意识与信息渠道的影响在较低层面显著,而在较高层面不显著。消费者认知行为的异质性为市场细分与开发提供了空间。厂商应针对不同群体采取差异化营销战略,引导消费者认知行为,促进潜在需求向现实需求转化。 相似文献

We develop a semi‐structural new‐Keynesian open‐economy model – with separate food and non‐food inflation dynamics to study the sources of inflation in Kenya in recent years. To do so, we filter international and Kenyan data (on output, inflation and its components, exchange rates and interest rates) through the model to recover a model‐based decomposition of most variables into trends (or potential values) and temporary movements (or gaps) – including for the international and domestic relative price of food. We use the filtration exercise to recover the sequence of domestic and foreign macroeconomic shocks that account for business cycle dynamics in Kenya over the last few years, with a special emphasis on the various factors (international food prices, monetary policy) driving inflation. We find that while imported food price shocks have been an important source of inflation, both in 2008 and more recently, accommodating monetary policy has also played a role, most notably through its effect on the nominal exchange rate. We also discuss the implications of this exercise for the use of model‐based monetary policy analysis in sub‐Saharan African countries. 相似文献

全球化是一个历史范畴,是世界各国各地区的经济、政治、文化等领域超越国界、扩大联系的历史进程和历史趋势。全球化加速了强势文化的扩张和弱势文化的萎缩,各种文化在融合的过程中趋同,全球化不断吞噬文化多元性。因此从对全球化、文化、文化的多样性及民族文化的概念界定,探析全球化对民族文化的影响及冲击。 相似文献

This study examined data from over 5000 organizations in 22 countries to address three complementary issues: (1) the influence of national culture on the adoption of diversity programs aimed at recruiting, training and promoting individuals from specific target groups; (2) the moderating effect of national cultural practices on the relationship between these diversity programs and the organizational outcomes of absenteeism and turnover; and (3) the mediating effect of absenteeism and turnover on the relationship between diversity programs and organizational performance and innovation. National cultural values and practices were taken from the GLOBE study and assigned respectively to the organizations in our sample. A multilevel path analysis supported the hypothesized effects of national cultural values on organizational diversity programs. Moreover, cultural practices were found to moderate the relationship between diversity programs and absenteeism and turnover. Our hypotheses on the role of absenteeism and turnover as mediators of the relationship between diversity programs and organizational performance and innovation were also supported. Our findings may help guide managers' decisions on the adoption of diversity programs in units operating in different national cultures. We discuss the implications of our findings for scholars and practitioners concerned with diversity management issues in a global context. 相似文献

欧盟食品安全技术法规体系的产生、发展现状及展望 总被引:1,自引:0,他引:1
欧盟食品安全体系被誉为全球最为成功的食品安全体系之一,而欧盟健全的食品安全技术法规体系,成为整个欧盟食品安全体系建设的重要基石。本文深入研究了欧盟食品安全技术法规产生和发展的各个阶段,阐述欧盟食品安全立法的运作模式,分析了欧盟现行“从农场到餐桌”全过程的食品安全技术法规体系建设的重点和所发挥的作用,并对今后欧盟食品安全技术法规体系建设的重点做了展望。 相似文献
