COVID-19: Evaluation of S&T Innovation Efficiency of 14 Prefecture-level Cities in Hunan Province under the Background of Climate Change-Based on Dynamic Network DEA with a New Framework

Abstract

With the urban development entering a new stage, science and technology innovation (S&T innovation) is becoming more and more important for urban development. Nowadays,the influence of global climate change on cities is increasing,and different cities have different climate changes,which have different degrees of influence on scientific and technological innovation in different cities.Urban scientific and technological strength plays an important role in urban economic growth, greatly promotes urban economic growth and industrial upgrading, and expedites the development of urban comprehensive competitiveness. At present, it is necessary to use dynamic network DEA method to study the efficiency of scientific and technological innovation of 14 prefecture-level cities in Hunan Province. Therefore, in this paper, the dynamic network DEA with a new framework was adopted to evaluate and study the S&T innovation efficiency of 14 prefecture-level cities in Hunan Province with the panel data from 2016 to 2021.The data of 2019 to 2021 include the data during the covid-19.dynamic network DEA is a new research framework that combines two-stage network DEA and Malmquist Index Approach to analyze the index of each prefecture-level city. Relevant suggestions were put forward according to the index. The results show that the tfp (total factor productivity) index values of S&T innovation in 14 prefecture-level cities of Hunan Province from 2016 to 2021 showed a gradual improvement trend; technological progress is an important factor affecting the tfp of S&T innovation; and there are regional differences in the tfp of S&T innovation in different cities.The suggestions put forward in this paper are as follows: policy support for scientific and technological innovation, scientific management, and strengthening the scientific and technological system of prefecture-level cities.
