Abstract:Based on the panel data of 9 prefecture-level cities in Fujian province from 2012 to 2021, applying the Malmquist index and the DEA-Tobit two-step method, this paper evaluates the efficiency of sci-tech innovation resource allocation in prefecture-level cities in Fujian province, and the causes behind the deficiency, then further explores the impact of digital economy development on the regional sci-tech innovation resource allocation efficiency. The research reveals an overall rise in the efficiency of sci-tech innovation resource allocation in cities in Fujian, but a significant difference in digital economy development between different regions. Besides, the development of digital economy has a significant positive impact on the efficiency of regional sci-tech innovation resource allocation, but the impact varies in different cities and regions. Therefore, it is suggested to take the development of the digital economy as a starting point to break down the barriers to the flow of sci-tech innovation resource elements, to give full play to the radiating and driving role of the central city in the coordinated development zone to achieve the coordinated development of regional sci-tech innovation, and to design differentiated optimal allocation paths for sci-tech innovation resources for different types of cities and regions.
