Abstract

The New Quality Productivity is the evolution direction of advanced productivity, which ensures the high-quality growth of marine economy in China. The marine economy is the key to constructing a strong marine nation. This paper empirically uses the spatial autocorrelation analysis and coupled coordination degree model to examine the spatial and temporal evolution characteristics of new quality productivity on the high-quality development of marine economy using 11 coastal cities and provinces' panel data from 2011 to 2020. It also investigates the correlation between marine new-quality productivity and high-quality marine economic development. The study found that: (1) marine new quality productivity has a positive-going promotion influence on the superior growth of the maritime industry; (2) marine new quality productivity's development level, marine economy's high-quality advancement level, and the degree of coordination coupling's degree of development of China's coastline comprises eleven provinces and cities show an overall upward trend. Yet, there are variations in the development of each province and city, the cities and provinces in the east and south being superior to the northern part of the country; (3)A feature of spatial clustering exists in the degree to which coastal cities and provinces' high-quality development is coordinated with the marine economy and new quality productivity. In addition, this study broadens the scope of new quality productivity and provides corresponding countermeasure suggestions for the excellent growth in the marine economy.
