摘要：In face of the emergence of knowledge-based economy and global competition,
countries in the world have actively increased sci-tech resources inputs and
accelerate R&D innovation. Medical device industry is the emerging star industry
under the time. Medical device industry with higher technology, large market
potential, high added value of output products, low pollution, emphasis on scitech
integration, and broad application presents higher risks but higher profi ts, is
a knowledge intensive industry, and will become a star industry leading global
economy. Medical biotechnology industry requires constant innovation that it
has long-term invested in large amount of R&D expenses for various patent
rights and R&D results to enhance the competitiveness. R&D expenses and
patent rights are therefore the key factors in medical biotechnology enterprises
maintaining the competitive advantage. The managerial level and employees of
medical device companies in Shanghai, as the research object, are distributed 300
copies of questionnaire. Total 232 valid copies are retrieved, with the retrieval
rate 77%. The research results show positive relations between R&D expenditure
and patent right, patent right and operational performance, and R&D expenditure
and operational performance. According to the results, suggestions are eventually
proposed, expecting to assist medical device industry in acquiring various patent
rights for the R&D inputs and maintaining the competitive advantage.
