Analyzing The Development of Technology from The Perspective of Patent: Taking Ships Diesel Engine as An Example

Abstract

It is an important strategic issue for enterprises and countries to analyze and study the patent of ships combination of diesel and diesel (CODAD), understand the process of technological development and identify potential research and development hotspots. This paper discusses the development status of the patent of ships combination of diesel and diesel (CODAD) from the aspects of language distribution, patentee and organization distribution, patent classification number distribution, etc. On the basis of using the LDA model to explore the core technology, the technical development level in this field is understood. The research on relevant patents shows that although the technical level of ships diesel engine in China has been greatly improved, there is still a certain gap compared with the leading countries.
