李彦勇  林润辉 《科技管理研究》2020,40(23):204-212

知识要素之间耦合形成的知识网络结构和跨界搜索是突破性创新形成的前端因素,知识网络结构特征和跨界搜索程度的不同,对突破性创新影响也不同。研究者利用美国人工智能技术领域的专利数据,构建了243家组织的知识网络,并考察了知识网络中心势、结构洞以及跨界搜索对相关组织的影响。研究表明,知识网络中心势、结构洞与组织突破性创新绩效呈正相关的关系;知识网络中心势、结构洞与跨界搜索呈正相关的关系。同时研究也验证了跨界搜索会正向影响突破性创新,并呈现部分中介效应。  相似文献   

基于三阶段DEA的人工智能上市企业创新效率评价     

徐书彬  黎新伍  李果 《科技管理研究》2020,40(5):165-172

以中国41家人工智能上市企业为样本,采用三阶段DEA模型对人工智能企业的创新效率进行有效测算。结果表明,企业规模、成立年限、政府补贴、地区对外开放水平和经济发展水平的提高有助于企业创新效率的提升,而股权性质、股权集中度和信息化水平则制约了企业创新效率的改进;清除环境影响和统计噪声后,多数企业的创新效率与纯技术效率上升,但仍处于较低水平;不同类型人工智能企业的创新效率存在差异,应用层企业最高,基础层企业次之,技术层企业最低。为了进一步提升人工智能产业的创新效率,政府应实施差异化战略,加大补贴力度,落实配套政策并加强知识产权保护;企业应扩大研发规模,完善管理机制,加强产学研合作,深化股权结构改革。  相似文献

山东省城市创新空间关联网络演变特征及影响因素分析     

曾文霞  董会忠  盛科荣  赵蕾 《科技管理研究》2020,(14)

基于2014～2017年山东省17个地级市创新联系能力,借助修正引力模型构建城市创新联系能力空间关联的有向加权矩阵,运用社会网络分析法及QAP回归方法探讨城市创新联系能力空间网络结构特征及空间传导关系的形成机制。结果表明：①山东省城市创新联系能力空间关联网络的网络密度加大,网络整体连通性增加,内陆中部、东部沿海地区城市处于网络的中心位置,易与其他城市发生空间关联,起到城市之间产生空间关联的“桥梁”作用。②内陆地区的“多三角型”与沿海地区的“倒T型”强关联网络得以扩展,边缘城市依赖于核心城市发展,形成具有较强关联的稳健性复杂创新网络。③地理距离、人力资本水平差异、政策支持力度差异、企业信息化水平差异对山东省创新联系能力空间关联网络结构的影响方向及回归结果较为稳健。  相似文献   

基于二级嵌套CES生产函数的工业企业创新效度研究——基于江苏省电子信息和新材料行业数据     

魏迎敏  刘钢  王继平 《科技管理研究》2020,40(17):163-172

对传统CES生产函数进行改进,构建三种二级嵌套CES生产函数,针对江苏省两大主导产业——电子信息、新材料进行创新效度评估。研究表明,对于电子信息行业,(LS)K嵌套方式的拟合度最好,且更倾向于"开放式创新"模式;对于新材料行业,(SK)L嵌套方式的拟合度最好,且更倾向于"封闭式创新"模式。最终,根据拟合结果并结合行业特征进行综合分析,给出针对性建议。  相似文献

物联网嵌入我国制造业企业——是否依然保持“微笑”?     

段玉婷  王玉荣  卓苏凡 《科技管理研究》2020,40(19):175-183

基于“微笑曲线”理论将企业创新划分为研发、生产、营销和服务四个阶段,应用DEA方法根据20家嵌入物联网技术的制造业企业2013-2017年间的创新投入、产出数据,对其整体及各阶段的创新效率进行了测评,得出以下结论：①从整体来看,各阶段的创新效率水平不再呈现“微笑曲线”分布,服务阶段的创新效率水平最好,且稳定;②从时间上看,企业整体综合创新效率变化不明显,但研发、营销和服务阶段的综合创新效率水平总体呈上升趋势;③物联网嵌入会在一定程度上提升企业的纯技术效率,但受规模效率的影响会使企业综合创新效率产生波动;④从投影分析来看,不同企业间及同一企业内部在各阶段的资源利用水平存在差异。  相似文献   

Demystifying blockchain: A critical analysis of challenges,applications and opportunities     

《International Journal of Information Management》2020

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.  相似文献   

Influence of organization learning on innovation output in manufacturing firms in Kenya     

《国际创新研究学报(英文)》2020,4(1):16-26

Knowledge entrepreneurship is increasingly becoming important in driving innovation for high levels of competitiveness. The purpose of this study was to investigate the relationship between Organization Learning (OL) and Innovation Output (IO) for improved performance in manufacturing firms in Kenya. The theoretical underpinnings on this study are the Schumpeter’s (1934) innovation theory of and the Gleick (1987) complexity theory. The methodology used was mixed method research because it provides a more holistic understanding of a thematic area. The research design that was used is cross-sectional design because it allows for making observations on different characteristics that exist within a group at a particular time. The target population was manufacturing firms across the country. Multi-stage sampling strategy was used to sample 303 respondents from 101 firms. Primary and secondary data were used to collect both qualitative and quantitative data. The questionnaire, interview schedule and a checklist of key informants were used to collect data. Content validity was used to ascertain the credibility of the research procedure and internal consistency technique was used to test for reliability. Correlation and linear regression were used to determine the relationship between OL and IO. Work disruptions were avoided by making prior arrangements and appointments. The findings indicate that OL has a significant influence on IO. It is recommended that lifelong learning, management support and risk tolerance should be encouraged to improve creativity. High creativity is important in raising the capacity to integrate internal and external knowledge for greater levels of IO. Further research should be carried out to find how customers and suppliers information can be utilized to enriched OL.  相似文献   

The Sources of Science Teaching Self-efficacy among Elementary School Teachers: A mediational model approach     

Ya-Ling Wang  Shih-Hsuan Wei 《International Journal of Science Education》2013,35(14):2264-2283

This study aimed to investigate the factors accounting for science teaching self-efficacy and to examine the relationships among Taiwanese teachers’ science teaching self-efficacy, teaching and learning conceptions, technological–pedagogical content knowledge for the Internet (TPACK-I), and attitudes toward Internet-based instruction (Attitudes) using a mediational model approach. A total of 233 science teachers from 41 elementary schools in Taiwan were invited to take part in the study. After ensuring the validity and reliability of each questionnaire, the results indicated that each measure had satisfactory validity and reliability. Furthermore, through mediational models, the results revealed that TPACK-I and Attitudes mediated the relationship between teaching and learning conceptions and science teaching self-efficacy, suggesting that (1) knowledge of and attitudes toward Internet-based instruction (KATII) mediated the positive relationship between constructivist conceptions of teaching and learning and outcome expectancy, and that (2) KATII mediated the negative correlations between traditional conceptions of teaching and learning and teaching efficacy.  相似文献
