The technological innovation effect of industrial chain under the 'double cycle' pattern in the post epidemic era

Abstract

In order to improve the economic benefits of enterprises under continuing influence of COVID-19, the technological innovation effect of industrial chain under the 'double cycle' pattern in the post epidemic era is studied in this paper. The fractional planning and integral planning functions of the industrial chain are obtained by constructing the CCR model, and the BCC model calculation of the innovation effect of the enterprise industrial chain is realised by the Chames-Cooper transformation. The data efficiency value of technological innovation effect of industrial chain under the 'double cycle' pattern is obtained via the SBM network model for analysis on the technological innovation effect of industrial chain. The experimental results show that the effect of industrial chain technological innovation is analysed from the aspects of main business income and the profit margin of enterprises extending the industrial chain and connecting the industrial chain. The highest profit margin after connecting the industrial chain technological innovation is 34.2%, which proves that technological innovation can improve the economic benefits of enterprises.
