ABSTRACT
This paper selects 12 indicators of 47 Chinese materia medica (CMM) listed companies from 2013 to 2017, and builds an enterprise competitiveness evaluation system. Firstly, the global principal component analysis (GPCA) method is used to aggregate 12 indicators into four principal components, which named as scale capability, profitability, growth ability and technological innovation ability, and calculate the competitiveness score of the enterprise. Secondly, the Q-type cluster analysis method is used to divide the enterprise into four echelons based on the competitiveness score of the enterprise, and then use the combination of dynamic and static to analyze the development status of the four types of enterprises from static and dynamic perspectives. This study finally drew relevant conclusion and suggestions, providing reference for the companies making a targeted development strategy.
ABSTRACT
Discrete industry is different from the complex industry, the patent citation between enterprises is the main channel of its dominant knowledge flow. In order to help the enterprises to find the imitative innovation objects and the investors to evaluate the value of the listed companies in the discrete industries, this study took the Chinese materia medica listed companies as the research samples, first used the social network analysis method to construct the visual flow chart of knowledge flow, then the K-means clustering was carried out by using the degree centrality and the betweenness centrality of the network graph, and the type of knowledge flow was divided and summarized. Finally, based on the previous classification of the main body, the binary logistic regression was adopted to explore the influence of patent factors and business factors on the knowledge flow from two dimensions of knowledge outflow and inflow. The results showed that enterprise age, technology width, enterprise scale and R & D investment had a significantly positive correlation with the knowledge outflow; The knowledge inflow was positively relative with R & D investment and the number of claims, while with significantly negative correlation with the enterprise age, technology width, scientific relevance and technical concentration.
ABSTRACT
With the development of economic globalization, "internationalization" has become the key word in the national economic development strategy. Chinese materia medica (CMM) is the treasure of ancient Chinese science, and now has entered the era of international development. CMM compound is an important part of CMM, and patent protection is an important guarantee for the internationalization of Chinese medicine products. This paper explores the factors influencing the international influence of CMM from the perspective of patents; Besides, this paper is based on the CMM listed companies' patents at home and abroad as the research object, establish the evaluation index of the international influence by combining the number of foreign applicants' patents that cite it and the number of citing patents' family number. Construct the patent index system to evaluate the international influence of patents, and explore the factors influencing the international influence of CMM patent by establishing count models. The empirical study found that increasing R&D team size, absorbing large areas of technology and more scientific literatures can enhance the international influence of CMM patent; Patents that protect effective sites, effective ingredients, and quality control/inspection methods can generate more profound international influence. At last, we put forward some suggestions to improve the international influence of CMM according to the results of empirical analysis.
