Analysis of Global Competition Situation of the Alternative Fuel Powered Ship Industry Based on Patent Information
With the increasing emphasis on environmental protection and sustainable development in the global shipping industry,the alternative fuel powered ship industry is facing opportunities for rapid development.The patent information analysis model constructed in this article combines information from the three dimensions of actual market demand,patented technology distribution and product competition landscape to analyze the industry competition situation and conduct an in-depth discussion of the patent layout in key technology fields.The study found that although the number of patent applications and ship orders in China is the largest,the quality of the patents is still poor,and there is a certain gap in the technology of medium and low-speed high-power engines.Based on this,the challenges and opportunities faced by industrial development are put forward,and in order to provide scientific references for formulating relevant policies and corporate strategies.
