摘要:专利保护和加计扣除政策是政府保护和激励私人技术创新的重要手段。本文利用2005-2015年间77家农业上市公司公开数据,研究了专利保护和加计扣除政策对私人农业研发投入与研发投入强度的影响。结果表明,专利保护政策并未促进私人农业研发投入或者提高私人研发投入强度,而加计扣除政策则显著提高了私人的研发投入和研发投入强度。通过设置专利保护和加计扣除政策的交互项,发现专利保护的增强削弱了加计扣除政策的溢入效应。本文结论验证了已有的部分研究结论,建议进一步完善专利保护政策,加强加计扣除政策的实施广度和强度,推动国家创新体系建设。 相似文献

Creating value in ecosystems: Crossing the chasm between knowledge and business ecosystems 总被引:1,自引:0,他引:1
Policy makers take initiatives to stimulate knowledge ecosystems in technology hotspots. It is implicitly assumed that these ecosystems will lead to value networks through which the participating companies can realize a competitive advantage. Value networks refer to business ecosystems where the value proposition is offered by a group of companies which are mutually complementary. The strategy literature suggests that business ecosystems lead to competitive advantages for each of the partners in the ecosystem. Based on a unique hand-collected database of 138 innovative start-ups in the region of Flanders, we analyze the knowledge and business ecosystem and the financial support network. We find that the knowledge ecosystem is well structured and concentrated around a number of central actors while the business ecosystem is almost non-existent at the local level. Further, we find that the financial support network is almost 100% publicly backed and fails to bridge the knowledge and business ecosystem. The implications for policy makers who tend to focus on the development of local ecosystems are discussed. 相似文献

This study examines the acceptance of cloud computing services in government agencies by focusing on the key characteristics that affect behavioral intent. The study expanded upon the technology acceptance model by incorporating contextual factors such as availability, access, security, and reliability. The research model was empirically verified by investigating the perception of users working in public institutions. Modeling results showed that user intentions and behaviors were largely influenced by the perceived features of cloud services. Also these features were found to be the significant antecedents of cloud computing usefulness and ease of use. The findings should guide governments' promotion of cloud public services to increase user awareness by enhancing usability and appeal and ensuring security. 相似文献

This study utilizes linear and log‐linear stochastic models to examine the impact that a variety of variables (including graduate education) have on M.S.W. students' desires to work in clinical practice. Data was collected biannually (between 1992 and 1998) from a complete population sample of all students entering and exiting accredited graduate programs of social work in California (n = 5,793). The influences of past practice experiences, professional motivations, socio‐demographic characteristics, ideological affiliations, and education and training experiences while a graduate students were all examined. Findings suggest that there is tremendous commonality in the variability of interest toward doing clinical practice among all student groups both before and after the completion of graduate studies. Male and female students, students of varied ethnic, social class and political identifications/affiliations, along with students of varied ages did not differ in their desire or interest to engage in clinical practice. The desire to prepare for private practice had the strongest influence—that was maintained over the course of their education—on students' interests in clinical social work. Desires to work with the poor were not associated with students' desires to be clinicians who wish to apply their trade across a wide variety of problems and populations. 相似文献

公共消费品的特性决定着其经营方式,各级政府经营和民营公共消费品时分别存在“非市场缺陷”和“市场缺陷”。“非市场缺陷”主要根源于“经济人”的本性与非市场体制不相容的一面,目前尚无克服这一弱点的有效途径。而“市场缺陷”主要是技术和交易方式落后造成的,随着现代科技迅猛发展和产权制度的创新,这种缺陷已呈缩减之势,因此,为了提高公共消费品经营效率,要优先采用民营方式。 相似文献
