Abstract:﹝﹞[Objective/Improvement] For the competitive intelligence needs of regional science and technology innovation, a competitive intelligence service system based on multi-resource integration, multi-agency linkage and multi-information sharing is constructed. [Method/Process] According to the needs of regional science and technology innovation mains, with the support of big data and Internet +, we will build a competitive intelligence linkage service system that is based on regional science and technology innovation demand and multi-party resources cooperation and sharing. [Results/Conclusions] Combining the construction of competitive intelligence service system driven by regional science and technology innovation, this paper explores the data supply and online collaborative service linkage mode under the regional competitive intelligence line, aiming at providing high quality and efficient competitive intelligence services for regional science and technology innovation development.
