Reinventing the Global Services Value Chain under the Wave of Digitization: An Analysis Based on Nonlinear Regression Models

Under the impact of digitalization wave, it is both a challenge and an opportunity for the global service industry value chain. Combined with the current development status of digital economy, it is proposed to use the entropy weight method to obtain the value of the development level of the former digital economy, while the value of the global services value chain is obtained by the trade value added method. The research variables are set, the data sources are determined, and the influence relationship between the two is explored using a nonlinear regression model. There is a significant positive correlation between the level of digital economy development and the status index of the global services value chain, and the status index of the global services value chain rises by 0.042 units for every unit increase in the level of digital economy development, which shows the interaction between the two, and provides guidance and reference for the reengineering of the value chain of the global services industry under the wave of digitization.
