We study the importance of individual characteristics and national factors influencing individual attitudes towards the impact of multinational corporations on local businesses. Our sample includes more than 40 000 respondents in 29 countries from the 2003 National Identity Survey conducted by the International Social Survey Programme. We find that individual demographic factors and socioeconomic status, such as gender, age, income and education, are strong predictors of their attitudes. For example, income and education are positively associated with favourable attitudes towards the impact of multinational corporations (MNCs) on local businesses while age is negatively associated with individual attitudes towards MNCs. In addition, hierarchical ordered logit model results show that approximately 8% of total variations in individual attitudes around our sample mean are not explained by differences in personal traits. Instead, they are due to country-level heterogeneity such as, but not limited to, different degrees of openness or different aggregate income. 相似文献

The concepts of technology convergence or technology fusion describe the phenomenon of technology overlap. Despite evidence of the higher value associated to interdisciplinary research and cross-industry innovation, few studies have investigated the characteristics of technology fusion based on patent data. This study identifies new cases of convergence relying on the International Patent Classification (IPC) of patents filed at the European Patent Office between 1991 and 2007: the first occurrence of a patent incorporating a combination of IPC subclasses signals a new instance of fusion. Duration models are employed to investigate the impact of field level characteristics derived from patent bibliometrics on the likelihood of identifying a new fusion. The results show that merges are more frequent if the focal technology fields are closely related (based on a higher number of cross citations), are characterized by wide technological scope, and are the result of an inter-firm collaboration. In contrast to previous findings, the results show that the more complex the technologies involved, the less the likelihood of their convergence or fusion. The correlation between fusion likelihood and the characteristics of the merging fields could help managers and policymakers to predict the emergence of new technology areas. 相似文献

Applying econometric techniques to EU28 panel data and controlling for explanatory variables such as road types, we find that increased truck load capacity does not necessarily aggravate road traffic safety. Specifically, heavy trucks do not seem to be linked with greater numbers of traffic fatalities/accidents, medium trucks appear to be the worst performers in terms of fatalities, and light trucks seem to be the worst for accidents. In summary, our results clarify the complex relationship between truck load capacity and road safety, pointing to the existence of a negative correlation for accidents per capita and an inverse U-shaped curve for fatalities per capita. 相似文献

近几年来,"省直管县"财政体制在各省陆续实施,其主要目的在于克服既有的市管县体制存在的各种弊端。可以预期,这项改革措施有减少行政管理成本、解决县乡财政困难、促进县域经济增长等多种潜在作用。但可能存在的问题是,该财政体制如何促进经济增长?文章利用江苏省51个县(市)2004-2009年的空间面板数据进行分析发现,"省直管县"财政体制对经济增长的作用主要是通过县(市)扩权而产生的"政府竞争效应"实现的。 相似文献

This article provides new evidence on the contribution of local banking to local economic growth (i.e. at county level – the Italian ‘province’) in Italy. A comprehensive data set is used, which includes control variables for social capital and human capital as well as indicators of the quality of local infrastructures and the production structure of the local economy. A linear within-estimator technique with fixed effects is applied to a modified version of the so-called Barro regression in order to address the well-known econometric issues of reverse causality and estimation bias resulting from unobserved district-specific influences. 相似文献

‘This study measured the effectiveness of US dairy export promotion programmes on increasing foreign demand and enhancing producers’ revenues. An import demand equation based on panel data was used to test whether export promotion has a positive and significant impact on US dairy exports. The effects of various promotion scenarios on the dairy market were then simulated, and benefit–cost ratios (BCRs) for these programmes were estimated. There were three key findings. First, the combined effort of public and private dairy export promotion expenditures had a positive and statistically significant impact on demand for US dairy products in the world market. The findings indicated that export promotion stimulated total dairy exports by 4.14 billion pounds, on average, per year, which represented 55.8% of total exports. Second, US dairy export promotion has been highly profitable for the nation’s dairy farmers. The calculated BCRs, based on assumed elasticity of supply, ranged from a low of 8.54 for the most elastic assumption to a high of 30.12. Third, from an optimality standpoint, dairy farmers are underinvesting in export promotion. The marginal BCRs ranged from a low of 3.79 to a high of 15.22, which means that, at the margin, increasing export promotion expenditures would be profitable for dairy farmers. 相似文献

专业分流是高校教务管理工作中一项重要的、具有复杂性的工作,随着高校招生规模的不断扩大,依靠传统手工的方式完成分流工作已不能够适应新形势下对专业分流的要求,设计开发一套基于教务管理平台的专业分流系统软件是非常有必要的。本系统采用分层设计思想、应用struts2开发框架,实现网上专业志愿填报、成绩计算、志愿成绩排名、专业分流录取等功能。本文给出了专业分流系统的设计和关键代码实现。 相似文献
