Abstract:Technology innovation has been the critical thrust in the industry clusters upgrading. From the view of patent analysis, this present study investigates the technology development in Dongguan, Shenzhen, Ningbo and Taizhou mould industry cluster, and explores the characteristics of technology innovation network in these four clusters. The analysis results revealed that patents out in mould industry concentrated in some geographic regions. The technological fields of patents in industry cluster had manifested different features in regional manufacturing industry. Leading firms have become the main innoators in the innovation of mould industrial cluster. Moreover, Cross-regional and cross-organizational technological cooperation are more prominent in the industry cluster. Finally, some policy suggestions for promoting the innovation and transformation of mould industry clusters have been put forward.
