通过考察多元场对钧瓷文化创意产业知识创造、流动及学习创新的影响发现:①场为主体的地理、社会及文化认知等临近等提供了条件,有助于经验意会及符号知识的获得、共享与传播,有利于思想的交流碰撞及创意萌生;②生产现场、地方关系场、地方社会场与临时性场在钧瓷的学习创新中发挥着不同而又相互补充的作用。生产场推动着集群知识积累和增进,地方关系场促进了行业知识、生产经验及家族核心知识的传播传承,地方社会场形成了地方共享知识信息,而临时场建立起外部通道联系,发挥着更新地方知识库的作用;③地方性的历史文化资源与传统以及地理-社会-文化等临近造就了外围地区文化创意经济的动力,但若未来本地知识更新的机制不够强大,则易产生发展锁定,这是需要未来引起关注的问题。 相似文献

全球—地方关系为产业创新研究提供了新的视角。本文基于全球(通道)—本地(蜂鸣)关系视角构建了软件产业集群创新效应研究的理论框架。以西安市软件产业集群为例,采用Stata13定量分析不同尺度创新合作的创新效应及其影响因素。研究发现,本地和国际创新合作均对集群创新具有积极的影响,且后者比前者的创新效应更强,说明搭建外部通道对集群创新的必要性;本地与国际创新合作交互对不同规模的软件企业产生的创新效应不同,对小型软件企业存在减法效应,对中型软件企业存在加法效应,对大型软件企业具有乘法效应。建立领先软件企业带动的开放创新系统,是西安市软件产业集群提升创新效应的有效路径。 相似文献

Previous research in the history of physics has led us to believe that Yoshio Nishina (1890–1951) virtually single‐handedly imported quantum physics into Japan. However, there are first‐hand accounts that Yoshikatsu Sugiura (1895–1960) also played an important role. Sugiura made his name in quantum chemistry with his contribution to the Heitler‐London theory of the chemical bond. Yet, historians of physics have paid scant attention to him. This paper brings forward information on Sugiura from his letters, his scientific papers, and his own recollections until ca. 1930. By examining this material, the present paper studies Sugiura's accomplishments in Europe and his contributions to the development of quantum physics in Japan. We conclude that Sugiura was one of the most important physicists when it comes to the arrival of quantum physics in Japan. In addition, we assess why he has been under‐appreciated in the history of physics in Japan. Our historical study on Sugiura suggests that, in addition to the position Nishina and his students rightfully occupy, there still are important unexplored aspects in the history of Japanese quantum physics. 相似文献

Having been adopted by legislatures in over a dozen states, postsecondary merit aid programs are largely concentrated in the southeastern United States. The observed clustering pattern seems to support previous evidence that policies spread between proximate states, a phenomenon referred to by political scientists as policy diffusion. Often, however, policy diffusion is not complete, and one or more states in a region fail to adopt. By interviewing policymakers throughout the southeastern United States—including actors in the three states in the region without merit aid—the study addresses the following question: Why do diffusion pressures lead to adoption in some states but not in others? Studying state “hold‐outs” promises not only to uncover the reasons for failed legislation in specific state contexts but also to better our understanding of the limits of diffusion theory. 相似文献

Science Cities: What the Concept of the Creative City Means for Knowledge Production. – The article aims to show that the relationship of science and the city has changed since the 1970s in the context of the knowledgeable society. While cities have principally been regarded as the typical space of science, of new ideas and innovation for centuries, since the 1960s and 1970s universities, research institutes as well as industrial research institutes have relocated to the periphery of cities. There, however, these sites of knowledge have been organized in an ‘urban mode’. That means that the concept of the city as a place of science and innovation has determined the architectural, spatial, and social organization of these sites on the periphery of cities. Certain features of the city have been copied, such as social infrastructures, places of communication, restaurants, cafes etc., while others have been left out – housing, cinema, theatre etc. An ‘urban mode of knowledge production’ in the sense of a very stylized model of the city has become a tool to enhance the production of scientific and technological knowledge. – The article exemplifies this by focusing on a case study, namely of the so‐called ‘Science City’ of the Siemens Company in Munich‐Neuperlach. 相似文献

顾炎武以"采铜于山"的话,形象地说明了学术原创性的重要性.原创性的研究不只是要从原始史料上入手,从思想史研究上说,从原著、代表作入手,要站在一个时代的理论高度从根本上进行阐释,与此同时,也要看到学术与社会现实的关联.要注意到"述"与"作"的关联、"众手修书"与"成一家之言"的关联,还要注意到比次之业、考索之功与独断之学的关联.学者应有原创性研究的自觉意识,意识到这是关系到学术发展的大事. 相似文献
