Research on the Impact of Digitization on the High-quality Development of Marine Industry
Digital economy,as an important driver of industrial transformation,is being gradually applied in the field of marine economy.This paper empirically examines the impact of digitalization on the high-quality development of marine industry from two dimensions:The transformation and the upgrading of marine industry,which are based on panel data of 11 coastal provinces from 2013-2019 and via fixed effect model and panel threshold model.It is found that digitalization enables the transformation and upgrading of the marine industry,with a more significant impact on the industry's transformation.The heterogeneity analysis shows that there is obvious regional heterogeneity in the effects of digitalization on the transformation and upgrading of the marine industry in the three major marine economic circles,with the promotion effect is shown as north>south>east.Further research found that the development level of marine economy is an important threshold variable.When the northern and southern marine economic circles crossed the threshold,the contribution of digital technology to the marine industry increased significantly,while when the eastern marine economic development level crossed the threshold,it weakened significantly.This study provides policy recommendations for the high-quality development of the digitalized enabling marine industry.The government needs to increase capital investment,appropriately move the marine economic development center to the north and south,and improve the ability of ocean-related scientific and technological innovation.
