数字出版供应链下区块链投资与版权保护策略
Blockchain Investment and Copyright Protection in Digital Publishing Supply Chain
摘要
Abstract
The immutability,security and traceability of the blockchain technology can be well used to solve the problem of piracy in digital content products.In this case,the decision-making issues of publisher optimal pricing and platform optimal copyright protection intensity in a digital publishing supply chain composed of publishers,sales platforms,and consumers in traditional copyright protection and blockchain copyright protection modes are explored,and the performance of the supply chain is compared.It is found that in the copyright protection mode under blockchain,platforms implement strict copyright protection,which increases the attractiveness of genuine products and compensates for the profit loss caused by publishers lowering prices to increase demand under traditional copyright protection.However,platforms are only willing to invest in blockchain when the investment cost is low,which cannot maximize the benefits of the supply chain.In response to this issue,contracts are designed which has increased the motivation of the platform to invest in blockchain.Finally,a study is conducted to investigate the impact of platform investment in blockchain on the consumer surplus and social welfare of consumers who purchase genuine products.It is found that investing in blockchain can improve social welfare,but will harm the consumer surplus of genuine products to some extent.关键词
