Abstract:The traditional manufacturing capacity sharing mode has some problems such as information asymmetry and credit system imperfections, the characteristics of blockchain: decentralization, de-trust and so on, which can effectively improve the shortcomings of the manufacturing capacity sharing mode. By studying the fit between blockchain and manufacturing capacity sharing in three dimensions: goals, subjects, and basic conditions, combining characteristics of blockchain: smart contracts, consensus mechanism and so on, a new mode of manufacturing capacity sharing based on blockchain is proposed to improve the traceability of the sharing process, realize the effective transfer of manufacturing capacity value, and promote the cooperative development of manufacturing industries.
