| 中文摘要: |
| 通过对相关专利数据的分析，可以客观地评价企业的技术竞争力，比较和分析同一领域内各个企业的研发重点、技术优势和劣势，有助于判断企业间的专利战略、创新能力和创新水平，具有十分重要的实践意义。本文以国外船舶柴油机推进系统领域为例，借助德温特的专利权人代码，绘制船舶柴油机推进系统领域的技术实力分布，利用波士顿矩阵图的思想衡量船舶柴油机系统领域具有竞争优势的企业，采用社会网络分析法对各企业的核心技术进行挖掘，基于S曲线对技术生命周期进行划分，并分析各个时段的企业集中度，从而预测未来的发展趋势。通过分析可以发现：MAUG-C拥有专利数量最多，之后依次为CSHI-C、MITO-C和SIEI-C等企业；借助专利数量和专利质量两个衡量标准，可以划分出该领域的优势企业、高产企业和高质量企业；柴油机及其相关的核心技术目前处于成熟期，未来几年相关技术专利将会逐步减少，优势企业逐渐在该行业占据垄断地位。 |
| 英文摘要: |
| Through the analysis of relevant patent data, the technological competitiveness of enterprises can be objectively evaluated, technological advantages and disadvantages of each enterprise in the same field can be compared and analyzed, which is helpful to judge the patent strategy, innovation ability. Based on the area of marine diesel engine propulsion system abroad, enterprises’ technology power distribution of marine diesel engine propulsion system can be mapped by means of the DII patent assignee code; The idea of Boston matrix chart is used to measure the enterprises with competitive advantages in the field of Marine diesel systems; The social network analysis method is used to dig out the core technology of each enterprise; The technology life cycle is divided based on the S curve, and the enterprise concentration degree of each period is analyzed, so as to predict the future development trend. Analysis shows that: MAUG-C has the largest number of patents, followed by companies such as CSHI-C, MITO-C and SIEI-C; By virtue of the two measures of patent quantity and patent quality, the dominant enterprise, high-yield enterprise and high-quality enterprise in this field can be divided; the diesel engine and its related core technologies are currently in the mature period. In the next few years, the related technology patents will gradually reduce, and the dominant enterprises will gradually occupy the monopoly position in the industry. Finally, some Suggestions on the development of marine diesel engine technology in China are put forward. |
