我国土壤改良专利技术发展态势分析

Analysis of Development Trend of Soil Improvement Patent Technology in China

该研究以incopat系统建立的土壤改良专利数据库为基础,采用专利计量学的统计分析方法,对我国近20年土壤改良技术专利数据结果进行了统计、分析和对比,直观地展现了土壤改良技术专利的申请趋势、主要申请人布局、法律状态、地域发展差距、专利技术生命周期。另外,从IPC号及土壤改良细分领域的发展历程角度分析了土壤改良技术的研究热点和方向,以期为我国土壤改良技术的研究与应用提供参考。

Based on the soil improvement patent database established by the incopat system,this paper uses statistical method of patent metrology to carry out statistics,analysis and comparison the patent data of soil improvement technology in China in the past 20 years.The result intuitively shows the application trend of soil improvement patents,the layout of main applicants,legal status,regional development gaps,and the life cycle of patent technologies.In the meantime,this paper also analyzes research hotspots and directions of soil improvement from the perspective of IPC number and the development succession in the field of soil improvement subdivision to provide reference for the research and application of soil improvement in China in the future.
