- Abstract:
- In order to distribute and allocate the science and technology innovation capital in various regions in a rational manner and improve the efficiency of science and technology capital, as well as study the issues in the input and output efficiency of urban science and technology innovation capital, this paper selects 11 regional central cities in China as the evaluation objects, and establishes an index system that takes R&D investment expenditure and technology introduction, digestion and absorption as input indicators, domestic patent applications, grants, and effective quantities as output indicators. The DEA efficiency evaluation model is adopted as the main research method in this paper, and the efficiency of science and technology innovation capital input and output capital in each city in 2017 is measured. The results are comprehensively analyzed and projected, while an empirical evaluation is conducted on the science and technology innovation capital efficiency. The study indicates that the total amount of science and technology input in the regional central cities is continuously increasing, but the gap in the input and output of science and technology innovation between cities is significant. Evaluation results show that Chengdu, Xi’an and Shenzhen are valid in the DEA method, while Chongqing, Beijing, Tianjin, Shanghai, Guangzhou, Wuhan, Nanjing and Shenyang are severely invalid in the DEA method. The reasons for invalidity include the insufficient use of capital input of science and technology innovation, and the low efficiency in the transformation of scientific and technological achievements, etc. The cities should increase the introduction of advanced technology and talents, give full play to the enterprises’ capabilities as the subject of innovation, enhance the science and technology innovation capital input and optimize the allocation of capital, strengthen the innovative capabilities and capital competitiveness of cities, and aim to implement a winwin strategic policy of resource sharing and complementary advantages among cities.
