This study investigates the performance effect of scientific knowledge in the context of highly science‐dependent industry. Given the popularity of sourcing scientific knowledge from science community, the purpose of this study is to investigate which firms gain greater benefits from scientific knowledge. From the perspective of absorptive capacity and combinative capability, we argue that both knowledge accumulation and knowledge combination moderate a firm's ability to capture value from scientific knowledge. Empirical data come from paper and patent citations and financial information in biotechnology and pharmaceutical firms. Results show that scientific knowledge alone has a positive effect on firms' financial performance. A firm's tendency to combination familiar and older technological knowledge amplifies the positive effect of scientific knowledge. However, knowledge accumulation, including R&D investment and patent stock, does not boost the positive effect.  相似文献

A destination's image and on-site recreation experience can be regarded as precedents of the authenticity perceived by heritage tourists. Historic images attract tourists to experience the authenticity of a heritage destination. This study examines the linear relationships among destination images, recreation experience, and the perceived authenticity experienced by tourists at the Shengxing Heritage Recreation Area in central Taiwan. In total, 536 usable questionnaires were collected. Analytical results indicate that the cognitive and affective images of a destination directly and significantly affect the recreation experience of tourists at a heritage recreation area. Additionally, recreation experience directly and significantly affects perceived authenticity. Moreover, recreation experience has a significant mediating effect on the relationship between cognitive image and perceived authenticity. We conclude that when tourists visit a heritage-based tourism destination, such as the destination under consideration, these tourists gain tourism image and recreation experiences, which strengthens their perceived authenticity of heritage tourism; as a result, these tourists are more likely to contribute to the development of heritage tourism. Applying this theoretical framework to research on heritage tourism further extends our understanding of the behavioural model of heritage tourists. Finally, this study provides a valuable reference for managers striving to develop heritage tourism.  相似文献

国际贸易结构分析:贸易品的技术分布   总被引:68,自引:4,他引:68  
对国际贸易结构的理论与经验研究已经充分揭示了技术在贸易中的重要作用。但是,对于如何识别贸易品的技术差异,如何分析贸易品的技术分布状况,进而如何从技术分布来分析贸易结构等,目前还没有非常成熟的方法。本文试图通过完善关志雄(2002)在这方面的努力来提供基于贸易品技术分布的贸易结构分析法。本文用显示技术附加值赋值原理作为识别贸易品技术附加值高低的理论基础,然后根据这一原理提供了具体的赋值方法,并提出了四种基于贸易品技术分布的贸易结构分析方法,分别是:竞争互补指数、竞争压力指数、技术高度曲线和贸易品高低技术分类分析法。最后,本文用上述方法分析了中国的对外贸易结构。  相似文献

One hundred and thirty-nine entrepreneurs in Ankara, Turkey were surveyed to determine their motivations for business ownership, the factors contributing to their success, and their problems. Based on survey responses, the primary reasons for starting a business are to increase income, to obtain job security, and to secure independence. According to the factor analysis, small and medium-sized enterprises owners are driven more by income rewards than intrinsic rewards. The most important business success variables are the entrepreneurs' reputation for honesty and friendliness. Social skills and good customer service were also cited as critical success factors. The most serious problem faced by entrepreneurs in Turkey is the complex and confusing tax structure. Other important problems include unreliable employees, the inability to maintain good records, and a weak economy.  相似文献

This paper aims to identify the effects of innovation on employment and labor composition in Taiwan. Using a new and detailed firm‐level data set, the empirical results determine that innovations, measured by R&D investments or patent counts, have a positive impact on employment. Both of the estimated employment effects of product and process innovations are overall significantly positive. Although the effects of process innovations differ between high and low R&D‐intensive industries, the process innovation tends to expand the firms’ output and then increase employment for high R&D‐intensive industries. However, it frequently results in laborsavings in terms of production work and reduces jobs in low R&D‐intensive industries. Moreover, technological innovations are found to be non‐neutral, leading to a shift in labor composition in favor of skilled and more educated workers.  相似文献

After evening out all the benefits and costs, the overall optimal level of democracy is about 3.2, on a scale of 1 to 7. On average, fully dictatorial countries have a conditioned growth rate of –1.113 percent, fully democratic countries have a conditioned growth rate of 1.146 while countries with the optimal level of democracy/autocracy have a conditioned growth rate of 2.665. In the case of a fully dictatorial country, moving one unit towards democracy can raise the GDP growth rate by about 1.725 points; while for a fully democratic country, moving towards autocracy by one unit can raise the growth rate by about 0.885 points. This study provides useful information for many developing countries which are experiencing substantial pressures to restructure their political system.  相似文献
