Research on the Development Trend of Ship Integrated Power System Based on Patent Analysis

Abstract

We can understand the technical strength and invention dynamic of other countries in this respect, and clarify the current technical theme and core technology by studying the patents’ status of foreign ship integrated power system, so as to accumulate experience and provide a reference for the development of ship technology in China. This paper demonstrates the development trend from the perspectives of technology development life cycle and direction of research and development based on the research about ship integrated power system, using the methodologies and tools of social network clustering, technology life cycle S curve, visual analysis, and so on. And the direction of research and development is illustrated from three aspects including technology concentration, industry concentration, and regional diffusion. The foreign ship integrated power system has entered the phase of rapid growth and Japan and South Korean are very competitive in this domain.
