The development of the marine industry plays a decisive role in future economic development. At present, the marine industry still has problems, such as the over-dominance of the primary industry and the slow development of the secondary industry in China. The purpose of this research uses the extended linear expenditure system to analyze the consumption structure and the relationship with marine industries, then find a path for improving innovation capability to promote the development of marine industries. This paper takes Liaoning Province in China as research object. The results show that this consumption structure has entered a stage of development consumption. In this context, the industrial structure coefficient and the industrial influence coefficient are used to explore the impact of the consumption structure changes on the marine industry and conduct industrial structure testing. The study found that the consumption structure has a greater impact on the marine industrial structure, especially in the secondary industry. Based on this analysis, this research builds a double helix innovative development path driven by technology and market.
