The presented research paper addresses the role of the stimulative effect of the digital economy in the high-quality development of the regional economy.Initially, we have developed individual assessment systems based on the level of development of the digital economy and the level of high-quality development in the regional economy. Using the panel data of 30 Chinese provincial regions (2014-2023) and combining the methodology of entropy weighting with TOPSIS (Technique of Order Preference by Similarity to Ideal Solution) method,the measurement of both aspects are obtained.Next, a benchmark panel regression model is constructed based on the multiple regression approach in order to study the relationship The correlation between the development of the digital economy and the rapid development of the regional economy with high standards.The results show that since 2014, there has been an exceptional growth in both the level of digitalization of China economy and the high-quality development of regional economies at overall growth rates of 447 percent and 87.60 percent respectively.The digital economy can be effectively used to support the high-quality development of the regional economy.Technological innovation can drive the high – quality development of the local economy. The computed metric for the extent of digital economy implementation stands at 0.318, and it has the most substantial promotional effect. When it comes to the impact on the high – quality development of the regional economy, the estimated coefficient of the digital economy in the eastern region is 0.175, which exerts the most notable influence. Subsequently, when considering the impact of the digital economy on local economic output, the central and western regions follow in sequence. In summary, fostering the growth of the digital economy, reducing the regional disparities, and advancing technological innovations are all crucial for enhancing the level of regional economic development.
