借助专利信息这一有效的技术信息载体形式,论文从专利地图的角度分析产业技术创新活动的演进与变化来把握广西地方产业核心知识演化,通过可视化数据挖掘工具,绘制出基于专利地图的广西地方产业技术领域演化路径图。研究表明,甘蔗制糖业作为广西地方特色产业技术演化较为缓慢并且缺乏内生的持续的创新驱动力量,但是产业技术演化趋势是存在的。最后从国际技术引进及地方化、产权保护与制度建设、加强内部交流促进创新协同等角度提出对策建议。

As for the resources constraint and the environment challenges to the development of local industries, Guangxi's sugar-cane industry is the typical, and with the high production cost and low product quality, the competitiveness of China sugar production is weak comparable with other countries even if there is huge demand in China. So it is important to analyze the role of technology that underpins the development of sugar-cane industry in the evolutionary view to explain the strange phenomenon in sugar-cane industry, in order to put some suggestions on the endogenetic path to participate in international competition for China sugarcane industry.Enhancing the competitiveness of sugar-cane industry has great theoretical and practical significance. From the view of evolutionary theory, at first, the authors hold knowledge is the core of industry development and knowledge itself is evolutionary also. In this paper, the authors try to discuss the path dependence of knowledge evolution with the tool of knowledge map which will illustrate the relationship of different technologies. Secondly, after comparing technology of Guangxi's sugar-cane industry in the global vision, the authors illustrate the path of technology, and with the data of the State Intellectual Property Office patent database, analyze the patent production with patent map for patent application trend chart, the patent growth rate analysis chart, IPC distribution chart, patentee distribution, patentee cooperation network, technology life cycle chat, and the patent maintenance time chart. Finally, according to the analysis, the authors put forward some constructive proposals, such as 1) two-step process should supersede the one-step process. 2) To strengthen the incentive mechanism to patent production, cooperation, and transfer. 3) Enhance the protection of intellectual property. Intellectual property is important to sugar companies.
