Innovation and Entrepreneurship Coupling Based on Simultaneous Equation Model and Its Energy Economic Effect Measurement

Abstract

In order to quantitatively analyze the synergistic relationship between the digital economy and high-quality development, the author proposes a measure of the coupling and coordination of China’s digital economy and high-quality development. Based on the data of 271 prefecture-level and above cities in China from 2016 to 2021, the coupling coordination degree model is used to examine the coupling relationship between the digital economy and high-quality development. The result shows that China’s digital economy and high-quality development are highly coupled, with an average coupling value of 0.9227. Conclusion. This study reveals the characteristics and facts of the coupling and coordination relationship between China's digital economy and high-quality development and provides useful policy inspiration for the central and regional formulation of differentiated digital economy development policies and high-quality development strategies.
