突破性技术创新是中国落实创新驱动、绿色发展、提升关键核心技术创新能力等多个国家战略的重要路径。本文采用文献计量方法和知识图谱工具,以2001—2018年发表于SSCI和CSSCI期刊的765篇文献为研究样本,从多个视角系统揭示国内外突破性技术创新研究的现状,并对未来研究方向进行展望。主要研究结论是:近18年国内外突破性技术创新研究发文量总体呈逐年上升趋势,国内研究与国外相比起步较晚且持续热度较低、对外合作研究较少且国际影响力不足;突破性技术创新研究遵循的理论基础主要是社会网络理论、动态资源管理理论和组织学习理论;突破性技术创新研究的热点主要集中于技术、组织、资源和财务四个方面,与市场发展问题相关的研究是薄弱环节。进一步从创新主体、创新变轨、研究层次和研究主题四个方面归纳了突破性技术创新研究热点的演化规律和存在问题。突破性技术创新的市场风险、跨国合作战略、大数据赋能和绿色导向会成为未来突破性技术创新研究的主攻方向。  相似文献

We examined 2007, 2010, 2012, 2014, and 2016 data from 49 countries to determine changes wrought by China’s Belt and Road initiative; we also used panel data regarding the Maritime Silk and Inland Silk Roads to test initiative effects on Chinese exports. Post-initiative infrastructure expansion and logistics performance improvements led to positive effects on China’s exports. Additionally, legal-system similarities and inland borders with trade partners had a more positive effect on Chinese exports in the Inland Silk Road, while population and free trade agreements were found to have a more positive effect on the Maritime Silk Road.  相似文献

The One Belt One Road (OBOR) project is perhaps China's most significant international relations initiative in recent times. It is based on openness, harmony, inclusivity, mutual benefit and market operations and aims to connect the economically vibrant East Asia and the developed Europe by land and by sea, and in the process, it brings growth and development to tens of countries along the modern Silk routes. In this paper, we compare the impact of the main initiatives of OBOR, namely enhancements in physical infrastructure and improvements in border administration, on the trade of countries that have signed on to this project, especially countries along the six economic corridors. We find overwhelming evidence that shows improvements in border administration has the greatest impact on exports of corridor countries. Although physical infrastructure is important for trade, the Chinese government should place equal attention to improvements in trade facilitation to ensure trade routes operate seamlessly across the various corridors.  相似文献

This study assesses the impact of traffic sign deficit on road traffic accidents in Nigeria. The participants were 720 commercial vehicle drivers. While simple random sampling was used to select 6 out of 137 federal highways, stratified random sampling was used to select six categories of commercial vehicle drivers. The study used qual-dominant mixed methods approach comprising key informant interviews; group interviews; field observation; policy appraisal and secondary literature on traffic signs. Result shows that the failure of government to provide and maintain traffic signs in order to guide road users through the numerous accident black spots on the highways is the major cause of road accidents in Nigeria. The study argues that provision and maintenance of traffic signs present opportunity to promoting safety on the highways and achieving the sustainable development goals.  相似文献

Cycling-inclusive urban planning is attracting attention worldwide because of the environmental, health, economic, and transport benefits inherent to cycling from the individual and the societal perspectives. The Czech Republic is one of the emerging cycling countries that are trying to promote and support cycling, but cycling mode shares are low because of the poor quality of the scarce infrastructure and the psychological barrier of the perceived lack of safety when cycling in mixed traffic. This study takes a multimodal approach based on the Theory of Planned Behaviour and focuses on the factors underlying the willingness to share the road from the perspective of cyclists and drivers: positive attitudes toward cycling, positive attitudes toward cyclists’ behavior, social norms toward cycling and anxiety to share the road. A web-based questionnaire was tailor-designed and administered in the Czech Republic via social networks, web forums, and the Civinet network, and a hybrid bivariate-ordered model tested the behavioral framework. Results show that the willingness to share the road as a cyclist or as a driver relates positively to positive attitudes towards cycling and cyclists’ behavior, and negatively to the anxiety of sharing the road. Moreover, mediator effects are observed and a clear relation emerges between the experience on the road as both a cyclist and a driver on the willingness to share the road as a cyclist. Lastly, results show that the factors underlying road sharing intentions are related significantly to gender, travel habits, and perceived personal and infrastructure-related barriers to cycling.  相似文献

China is a major funder of developing country infrastructure, lending $40 billion annually through policy banks. Lending does not favor the belt and road above other regions. China’s lending is indifferent to risk, that is, it is uncorrelated with indices of political stability and rule of law. Some major borrowers with poor governance are beginning to have debt sustainability problems, while other borrowers are in good fiscal shape. Chinese banks have been reluctant to follow global environmental norms but seem to be evolving in that direction. Chinese actions seem more a revision of the global system than a challenge to it.  相似文献

This study aimed to identify the roles of laypeople at road traffic injuries (RTIs). A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words of ‘laypeople’, ‘layman’, ‘layperson’, ‘bystander’, ‘first responder’, ‘lay first responder’, ‘road traffic’, ‘road traffic injury’, ‘crash injury’, ‘crash scene’, ‘emergency’, ‘trauma care’, and ‘prehospital trauma care’ were used in combination with the Boolean operators OR and AND. We did electronic search on Google Scholar, PubMed, ISI Web of Science, CINAHL, Science Direct, Scopus, ProQuest. Based on the reviewed studies, some factors such as cultural conditions, knowledge, relief agencies, and demographic factors affect the interventions of laypeople at the crash scene in functional areas. Regarding the permanent presence of people at the crash scene, the present study can provide an opportunity to reduce different side effects of RTIs imposed on the society.  相似文献
