Based on eight engineering departments in Tsinghua University, this paper tries to investigate how social capital affect the research output and the associations between different dimensions of social capital. The results indicate scientists with higher structural dimensions in co-authorship networks have higher citation count. Due to discipline differentiation, relational capital and cognitive capital are positively related to citation count in some departments. The associations between relational, cognitive capital and structural capital are positive to some extent, which may help scientists to obtain advantage positions in co-authorship network.
The role of breakthrough technology invention in the participation of enterprises in global technology and market competition has been widely recognized, but how to search and recombine the knowledge elements to create breakthrough inventions is still a hot issue in the academic and business circles. Based on the knowledge recombinant search perspective and social network theory, this paper investigates the relationship between knowledge element network search and the creation of breakthrough invention, and reveals the moderating effects of inventor team characteristics based on team learning theory. Then, the empirical test was conducted with 6,132 granted invention patents in the field of nanotechnology from the United States Patent and Trademark Office (USPTO) during 1995-2010. The results show that first, the lower the network centrality of knowledge elements and the fewer the structural hole of knowledge elements, the higher the likelihood of forming the breakthrough inventions. Second, compared with the collaborative inventors, the lone inventor's search for knowledge elements with lower network centrality and fewer structural holes will have a higher likelihood of creating breakthrough inventions. Third, the richer the technology experience of the inventor team, the higher the likelihood that it creates breakthrough inventions by searching for knowledge elements with lower network centrality and fewer structural holes. This study reveals the formation mechanism of breakthrough inventions from the perspective of both knowledge elements and inventors, which has important implications for firms’ team building and knowledge combination strategy in the pursuit of breakthrough inventions.
In the context of great power competition, the 337 investigation increases the risk of intellectual property friction between China and America. This paper discusses the nature of the 337 investigation from the perspective of “America first”, analyzes the current situation of the China-related 337 investigations and predicts the trend of the investigation based on the discussion of the Sino-US “asymmetric” competition pattern as well as relevant policies of the United States. According to this paper, the number of China-related 337 investigations will still rank the first in the world, while the future areas need to be focused are 5G communication, artificial intelligence and biomedicine. Finally, this paper puts forward corresponding policy suggestions, aiming to help enterprises accomplish the “going global” strategy successfully and enhance the international discourse power of China in the intellectual property protection system.
Using the Innovation Theory and the Innovation Ecosystem Theory, this paper studies the hot issues such as the private nature of the financial Scientific and Technological Achievements(STA) and the Intellectual Property Rights(IPR), the characteristics of IPR assets, the IPR ownership allocation and devolution , and the IPR price accurate evaluation. The State-Owned Assets Management is not the main problem hindering the STA transformation and the IPR application. The internal technology transfer institutions of the university and the research instituters can effectively solve the problems of supply and demand mismatch, asymmetric information and risk, and patent rights owned by different people in one technology technology transfer. It is needed to set up this kind of institutions and talent team wirh patent management, technology transfer and seed investment functions which can form a mechanism of "mutual support and restraint". For financial STAs and IPRs that have not been transformed and implemented within a certain period of time, and that do not involve public welfare or that have fewer patent rights, the ownership or long-term use right of them can be delegated to researchers in service who has completed the STAs and IPRs .
The root of artificial intelligence is the liberation of repeated heavy labor and the replacement of labor population shortage. The more scarce the labor population, the higher the marginal cost of increasing labor force. The greater the marginal value of artificial intelligence substitution creation, the more obvious the effect on economic promotion. Through the empirical research of artificial intelligence substitution enterprise labor force in Qingdao, it is found that intelligent substitution promotes the outflow of human capital in manufacturing industry, the inflow of human capital in service industry, Promote the promotion of human capital education and integration, post and wage income. The article suggest that we should enhance the guiding consciousness of "intelligent substitution for artificial ", attach importance to the effective promotion of" low cost strategy "of artificial intelligence, and strive to promote the accurate implementation of" human capital promotion ".
The spatial agglomeration of industries has become an important phenomenon in modern urban economy. The coagglomeration of manufacturing industry and producer services is of great significance for transforming the mode of economic growth driven by single industry, integrating and extending regional resources and industries, and improving urban total factor productivity. Therefore, taking 27 central cities of Yangtze River Delta as the research object, the paper analyzes the influence mechanism and industry heterogeneity of coagglomeration of manufacturing industry and producer service industry on urban total factor productivity. The conclusion shows that industrial agglomeration has a positive effect on urban TFP. From the perspective of industry segmentation, the coagglomeration of real estate industry and manufacturing industry, transportation, warehousing, post and telecommunications industry and manufacturing industry has no significant effect on the promotion of urban total factor productivity, while the coagglomeration of scientific research, technical service and geological exploration industry, information transmission, computer service and software industry, financial industry, leasing and business service industry and manufacturing industry can improve urban total factor productivity. Therefore, the city should improve the diversification of industries, based on its own advantages, choose different subdivision industries to focus on training.
The cross-border innovation of emerging technologies has promoted the trend of the cross-border integration in the internal knowledge network. This paper analyzes the evolution of the knowledge flow path and the structural characteristics of an emerging technology knowledge network with the development of cross-border integration based on the patent data coming from DII (Derwent Innovation Index), which targets the field of virtual reality technology and uses social network analysis method as well as patent citation network.The results show that the emerging technology knowledge flow path evolves from one-way path to mixed path to two-way path, and the continuous increase of both core and peripheral enterprises widens the development space of the two-way path.The number of knowledge fiow path has increased sharply and the direction of that has dispersed,which leads to the emergence of the cross-border integration of knowledge networks between enterprises and regions. And the cross-border integration is characterized by increased heterogeneous knowledge, flexible knowledge connection and expanded network scale.The central enterprises and central regions further strengthen the cross-border integration capacity through the knowledge flow preference of "Central regions cite the domestic knowledge and non central regions cite the knowledge in central regions",reflecting obvious first mover advantages.
Scientific collaboration plays a key role in producing scientific knowledge, which is vital to the success of firm technological innovation. We investigate 585,348 co-authored research papers published in the Web of Science during 2000 to 2017 in disciplines relevant to the new energy vehicle industry. We discovered 139,090 inter-organizational scientific collaboration ego-networks involving 32,715 Chinese organizations. Meanwhile, we collected data on 16,112 patents applied by 1,893 Chinese organizations in the industry from the Derwent database. We use co-authored papers and patents applied by 174 focus firms and other organizations as panel data to empirically analyze how scientific collaboration network relation affects firm innovation in Chinese new energy vehicle industry. The study findings show, both relation breadth and relation strength in the scientific collaboration network can positively affect firm innovation, and the relation strength has a more direct impact than the relation breadth. Knowledge diversity (interdisciplinary and technology diversity) are mediating variables between network relations and firm innovation. Interdisciplinary is a mediating variable between relation strength and firm innovation, while relation breadth influences the firm innovation through technology diversity. Besides, both interdisciplinary and technology diversity are beneficial to firm innovation.
：Global technology competition has changed from single technology competition to common technology competition, from enterprise core technology competition to industry generic technology competition; "platform" and "innovation and reproduction" as the core characteristics of common technology, put forward special requirements for the spillover and diffusion of generic technology. In this paper, 373 strategic emerging enterprises are taken as research samples to investigate the impact of the characteristics of patent cooperation network on the spillover of generic technology. The results show that: the relationship between the scale of patent cooperation network and the spillover of generic technology is inverted U-shaped; network relative centrality has a significant positive effect on generic technology spillover, and technology proprietary has a negatively moderating effect on the relationship between scale of patent cooperation network and the generic technology spillover, and the relationship between network relative centrality spillover. The research of this paper promotes the understanding of the relationship between patent cooperation network and generic technology spillover performance, and also provides enlightenment and suggestions for enterprises to build appropriate patent cooperation network and technology proprietary, so as to promote generic technology research and development and spillover.

The continuous evolution mechanism of innovation is always the focus among academic, business and government. In this study, the object of innovation ecosystem is the key point which we understand continuous evolution mechanism of innovation ecosystem, we think that the object of innovation ecosystem changing and evolving the innovation ecosystem continuing evolution. Based on the government and firm view, we conclude four models of continuous evolution ecosystem. Namely, governments, as the main body of area-level and national-level innovation ecosystem, can set the object, change the environment and ensure the evolution process. On the other hand, firms always adjust the strategy and open the capability boundary to design the object of innovation ecosystem. So, beyond the interactives of firm-level innovation ecosystem and focus on the objects of different levels innovation ecosystem will help us get more insights for continuation evolution of innovation ecosystem.
Abstract: Based on the data of green patents of listed companies in Shanghai and Shenzhen stock markets from 2004 to 2015 as samples, establishing a comprehensive measurement index of environmental regulation and using systematic GMM estimation method, the influence characteristics and mechanism of environmental regulation on enterprises' green technology innovation is studied, with the heterogeneity research on green patent types, enterprise ownerships and industry types. The environmental regulation has a “U” shaped influence on the green innovation of enterprises in which green innovation is suppressed first and then enhanced; In green innovation activities, environmental regulation tends to promote the creation of green invention patent with higher value; Non-state-owned enterprises have a lower tolerance for environmental regulation, and have a preference for more valuable green invention patents, while the inflection point of its “U” curve comes earlier; There are differences in the “U” shaped impact of environmental regulation on green technology innovation between the cleaning industry and the pollution industry, the cleaning industry mostly reflects the right half of the “U” shaped curve with an early inflection point, while the pollution industry fully reflects the whole “U” shaped curve with a late inflection point. Therefore, adopting flexible and differentiated environmental regulation policies plays a positive role in promoting green innovation and green development.

As an important way and means for latecomers to catch up with innovation, radical innovation is attracting wide attention in the academic and industrial circles. Using the method of case study, this paper makes an in-depth discussion on the relationship between capability evolution, institutional supply and radical innovation of latecomers. It is found that the pursuit of the goal of radical innovation in latecomers needs the combined effect of internal capability and external institution. With the dynamic evolution of latecomers’ capability from ordinary capability to high-level capability, from enabling capability to empowerment capability, and the change of government industrial supply from administrative intervention to perfect service, from single policy to policy integration, latecomers have gradually completed the transition from "innovation following" to "innovation breakthrough" to "innovation leading". The above findings reveal the law of synergistic co-evolution among capability, institutional supply and radical innovation, which is of great significance for deepening theoretical understanding and carrying out theoretical practice.
