Comparative Study on Indigenous Innovation Resource in Pharmaceutical Fields:An Entropy Measure over Patent Data in China
It is widely believed in international literature that R&D and related innovation movement in pharmaceutical field is different from activities in other manufacture areas. This paper deals with the nature of innovation activities in Chinas pharmaceutical field, focusing on innovation activities in its size and technical scope, by investigating patent data in China between 1985 and 2005. Entropy measure is introduced in this paper to reveal degree of concentration and diversification. With data processing result based on entropy measure, the paper provides a descriptive chart in two dimensions: namely, degree of size and degree of technical scope. Patenting activities from foreign firms and local firms are compared in this study, and development tendency of technology resources in local companies in China is also provided comparatively. Implications from this research can be used as reference to policy makers and business companies in China.
