The economic benefit of marine based on DEA model

With the development of China’s economy, the marine economy has been an important way of increasing national economic output value. However, the marine economy is still at the initial development stage. The theory and management of marine economy and resulting economic output value has not been able to satisfy the requirements of the overall economy. To increase the impact of the marine industry on the overall economic increase, the economic benefits in marine environment needs to be investigated and discussed. Using a Data Envelopment Analysis model, this study conducted data analysis for regional marine environments, noted relatively optimal aspects of marine economy based on the analysis results, analyzed an aspect of marine economy which is urgent to be improved, and suggests other solutions. Finally, the development prospects of marine economy were evaluated. This work aims at maximizing the economic output of marine environment and provides guidance for the development of marine economy. Some problems existing in the development of marine economy in coastal provinces were discovered, and suggestions, and counter measures were proposed to solve those problems.
