Collaborative Innovation Network, Knowledge Base, and Technological Innovation Performance-Thinking in Response to COVID-19.

Amid the pandemic of COVID-19, the collaborative innovation network of enterprises is conducive to the sharing of innovation resources, knowledge transfer, and technology diffusion, which is closely related to the improvement of corporate technological innovation performance. Based on the patent application data of listed enterprises in Jiangsu, Zhejiang, and Shanghai in China, this study constructs a cooperation matrix, describes the characteristics of collaborative innovation network from two dimensions of network structure and network relationship, introduces the breadth of the knowledge base as a moderating variable, and analyzes the nexus between characteristics of a collaborative innovation network and technological innovation performance. Based on the panel data of 193 listed companies in Jiangsu, Zhejiang, and Shanghai, this study uses a multiple linear regression model for empirical analysis. The results show a U-shaped relationship between clustering coefficient and technological innovation performance. The breadth of knowledge base strengthens the positive relationship between the structural hole and technological innovation performance. In contrast, the breadth of knowledge base weakens the positive relationship between network relationships strength and technological innovation performance. The study findings will enhance enterprises' participation in a suitable collaborative innovation according to their knowledge-based characteristics and improve the technological innovation performance.

The preparation of cold -dampness medicine iron stick and treatment clinical observation of cold -dampness lumbago / 中国基层医药

Objective To investigate the preparation process of cold -dampness medicine iron stick and the curative effect of cold -dampness medicine iron stick,thus to provide reference for the clinical treatment of cold -dampness lumbago.Methods Using science and technology of preparation and the thermal effect of cold -dampness medicine iron stick was observed.1 20 cases with cold -dampness lumbago of dampness type with low back pain, according to the order of treatment were divided into the observation group and control group.63 cases of the treatment group were given cold -dampness medicine iron stick affixed to the surface of the skin,57 cases of the control group were given kanlisha affixed to the surface of the skin.The treatment effect after one course of treatment was observed. Results Cold -dampness medicine iron stick heat effect index of heat time was 1 2min,to thermal time was 1 0.8h, the highest temperature was 56.5℃,thermal equilibrium curve was gentle and lasting.The efficacy of the two groups of drugs within the observation time effect was obvious.The total effective rate of the observation group was 90.5%(57 /63),which was higher than 75.4%(43 /57)of the control group,the difference was statistically significant (χ2 =4.87,P <0.05).During the treatment,local skin blisters,rash,itching and other low temperature burns and other allergic reaction were not found.Conclusion Cold -dampness medicine iron stick process is stable and controllable in quality and heat balance curve slow long -lasting,determine the efficacy,innovative therapies,it is easily accepted by patients and worthy to be popularized in clinical practice.
