Effect of Digital Economy on Marine Economic Development Level by Big Data Analysis

Abstract

Digital economy is a new factor to promote regional development. To explore the impact of the digital economy on the level of marine economic growth, we establish a panel threshold model with capital for marine as the threshold variable and marine economic growth level as the explained variable based on the neoclassical economic growth theory and the panel data of regions in China during 2006 to 2016. We performed a threshold regression analysis to understand the digital economy’s influence on marine economic growth. The results show that the impact of the digital economy on marine economic growth has a double threshold effect. When the marine capital investment is low, the digital economy influences marine economic growth negatively. When the digital level reaches the medium level, the digital economy enhances the growth of the marine economy significantly. However, if the digital level reaches a high level, its role in promoting marine economic growth is weakened.
