Abstract:Each industry has its own development law in the integration path, while the mechanism behind the integration of two chains affecting different industries has common characteristics. Therefore, this paper constructs a comprehensive and systematic analysis framework from the perspective of the integration path and mechanism of the two chains. There are three main integration paths, namely, the extension of the innovation chain to the industrial chain, the extension of the industrial chain to the innovation chain, and the construction of a bridge for the integration of the two chains; The integration mechanism mainly includes allocation of innovation resource, the management of innovation project, the cooperation of industry and university and the share of innovation resource. Based on this theoretical framework, taking Shenzhen as an example, this paper puts forward suggestions to promote the integration development of two chains.
