By integrating external factor evaluation （EFE） and internal factor evaluation （1FE） matrix, this study proposes a new technology selection method. The proposed fi＇am^work is applied to a real technology selection problem faced by a bio-technology enterprise in the context of China＇ s economic, political and social environment. Two major aspects and 24 external/internal factors are determined. This study uses analytic hierarchy process （AHP） method to sort the information and derives weights of each criterion. Empirical results indicate that the candidate technology is promising, and shall be developed as one of the enterprise＇s primary products.展开更多

We draw on diverse data to demonstrate the unique development trajectory of the industry in China. China has benefited through targeted spin-offs of R＆D-oriented foreign direct investment from developed countries driven by the effects of globalization, government-encouraged collaboration between the domestic academia and industry, and the input of overseas returnees. Together with an increasing focus of the government and domestic enterprises on independent innovation, such developments have enabled China to catch up with the global biotechnology industry. However, its small scale and low capacity for commercializing innovations under China ＂s current regulations and other barriers pose challenges for the development of the industry. Suggestions for the sustainable development of China＇s biotechnology industry are presented in this study.展开更多
