Abstract

Abstract: In this paper, taking the patent star database as the data source, the technical life cycle, patent core technology area, organization types of right holder and the advantage patent technology of region were deeply studied, based on the analysis of the patent application age, technology field, rights holders and regional distribution in Zhejiang Province from 2008 to 2017. The results showed that Zhejiang sewage treatment technology was in the rapid development period of technology life cycle; the core technology of sewage treatment patents in Zhejiang Province was highly concentrated, mainly in 12 IPC classifications such as C02F 9/14, C02F 9/04 and C02F 9/02. Affected by the technical force and industrial policies, the regional difference of advantage sewage treatment technology in Zhejiang province was obvious.

Key words: sewage, patent, literature analysis, technology innovation
