主　　题：port supply chain blockchain technology investment technology sharing co-opetition 

摘      要：Blockchain technology plays a very positive role in promoting the development of the port supply chain.Although there are some practical examples of blockchain in the port supply chain(eg.Trade Len or Cargo Smart),there are few application scenarios.Therefore,blockchain technology has yet to be widely used in the port industry.This may be related to the construction of blockchain.This paper analyzes the impact of blockchain technology on the port supply chain and the technology sharing on the shipping market.It is found that the investment of blockchain technology in a competitive environment has different characteristics.When the efficiency of technology investment and the proportion of market expansion reach a certain combination,there are two different equilibrium strategy choices:Only technology investment or technology sharing.Based on the above research results,this paper further investigates the results of the comprehensive influence of different factors such as competition intensity and market expansion proportion.
