Analysis on the Operation Efficiency of China's Marine Transportation Industry and Its Influencing Factors

China's marine transportation industry needs to change its current operation mode and improve economic efficiency, so that it can survive in the turbulent market. Based on the DEA model, it measures the eleven coastal provinces and cities' marine transportation industry efficiency by taking the number of berths and their berths as input indicators and the coastal port cargo as throughput, international standard tank throughput and passenger throughput as output indicators. Then, a regression analysis of China's marine transportation industry and its influencing factors is done by using EVIEWS software. It is found that the operation efficiency of China's marine transportation industry is good, but still needed to be improved. The investment in fixed assets of the coastal transportation industry and the container capacity of the wheel barge and its power have a positive effect on the operation efficiency of the marine transportation industry. Measures in the fields of ports, fleets, employees and waterways should be taken to solve those problems.
