Research on urban innovation efficiency of Guangdong-Hong Kong-Macao Greater Bay Area based on DEA-Malmquist model

In order to scientifically evaluate the allocation efficiency of science and technology innovation system and build a good science and technology financial environment, this paper constructs an evaluation index system based on the panel data of 11 cities in Guangdong-Hong Kong-Macao Greater Bay Area from 2010 to 2019. By using the Three-stage DEA model and Malmquist model, this paper makes a static and dynamic analysis on the efficiency of scientific and technological innovation, calculates the efficiency of scientific and technological innovation, and reveals its internal reasons. The results show that: the productivity of scientific and technological innovation in Guangdong-Hong Kong-Macao Greater Bay Area has been steadily improved; technological progress is the key factor to promote the productivity of scientific and technological innovation; there are differences in the efficiency of scientific and technological innovation in the same city, and the efficiency of scale has inhibited the efficiency of scientific and technological innovation to a certain extent.
