Based on the development of the digital economy and the uncertainty of demand information in the equipment manufacturing supply chain, the impact of government subsidies on the information sharing strategy under the equipment manufacturers quality innovation was explored. The price and quality innovation decision models for non information sharing and information sharing were established and solved, and the model results were analyzed. Results show that retailers sharing optimistic demand can definitely motivate equipment manufacturers to improve product quality, but it may not necessarily increase wholesale and retail prices at the same time. Moreover, it is only when government subsidies are high that it helps to increase the actual demand for products. Equipment manufacturers always benefit from information sharing, and designing an information compensation mechanism can increase the motivation for retailers to share, but this mechanism requires government subsidies to be within a certain range. In addition, the increase in government subsidies helps to enhance the consumer surplus value and social welfare value of information sharing.
