Technological Innovation, Regional Heterogeneity and Marine Economic Development——Analysis of Empirical Data Based on China's Coastal Provinces and Cities

In order to analyze the impact of technological innovation and regional differences in marine economy on the development of marine economy, the paper uses the regional panel data of China’s total marine production value from 2006 to 2015, and uses the Theil index to measure regional differences in the marine economy based on the logarithm of the Cobb-Douglas production function. Finally,the paper establishes a random effect panel data model for empirical analysis. The research indicates that the regional differences in the marine economy show a narrowing trend, which promotes or inhibits the development of the marine economy; The extent of the impact of regional differences in the marine economy on the development of the marine economy is inconsistent; Scientific and technological innovation in various regions has promoted the development of marine economy.
