Empirical Research and Analysis on the Development of Digital Economy and Communication Industry - Taking the Chengdu Chongqing Economic Circle as an Example

As a key link between production and consumption, the level of development of the circulation industry will greatly affect prosperity of a region. In the context of the digital economy, improving the efficiency and competitiveness of the circulation industry is of great significance for building a new development pattern of "dual circulation". This article uses panel data from 15 cities in the Chengdu Chongqing Economic Circle from 2014 to 2021 to quantitatively evaluate the development level of digital economy and circulation industry in each city using the entropy method, and conducts empirical research on the degree of correlation between the two. The empirical results show that the degree of digital economy development in Chengdu-Chongqing twin city economic circle will have a significant impact on the circulation industry of the cities in the circle. So, it is a wise choice to accelerate development of circulation industry and promote urban prosperity by strengthening construction of digital economy infrastructure, increasing the construction of circulation infrastructure around Chengdu economic circle and coordinating the development.
