Information Sharing and Shareholding Strategy for a Low-Carbon Supply Chain in the Blockchain Era

This study examines a low-carbon supply chain consisting of a retailer who has private demand information and a manufacturer who adopts carbon reduction technology. Supply chain members need to make optimal decisions about shareholding strategy and information sharing. The manufacturer produces low carbon products and determines the low carbon level in the blockchain era. With the use of blockchain, consumers' low carbon awareness level is improved. There are four cases (case, case, case, and case) comprised of shareholding strategy and information sharing. For the shareholding strategy, the retailer prefers no shareholding strategy to get the whole retailing profit. The manufacturer tends to hold the retailer's shares and wants a slice of the retailer's profits. The reason is its investments in blockchain technology and carbon reduction. For information sharing, the manufacturer needs to predict the uncertain demand when it has no accurate demand information. Therefore, the manufacturer is inclined to obtain the full of market demand. However, the retailer may choose to protect its private demand information value. In addition, blockchain improves low carbon awareness, which strengthens supply chain members' attitudes toward sharing strategy.
