In mid-2017, a supply constraint analyst at General Motors (GM) was working on two electric vehicles: the Chevrolet Bolt EV for the US market and a similar Buick model to be marketed in China. GM had chosen to work with only one supplier for the vehicles’ lithium-ion battery: Morningside Power Storage of South Korea. However, since making that decision, consolidation in the freight shipping industry had led to higher shipping costs, and China had introduced regulations to restrict and discourage the importation of batteries. The supply constraint analyst needed to decide where the battery cell manufacturing and battery pack assembly should be located and the production levels necessary to meet, at the lowest cost possible, the needs of both the Chevrolet Bolt EV in the United States and the Buick version in China.

In October 2019, BYD Company Limited (BYD), a leading Chinese company in the new energy vehicle industry, was pursuing the goal of building a business ecosystem. The firm and its partners jointly launched a blockchain-enabled green ecosystem that delivered new value to customers by issuing carbon points to users who had made efforts to reduce their daily carbon emissions. Users could spend carbon points at partner merchants and get rewards. Blockchain, as the core infrastructure of the project, provided an ideal environment to cultivate a healthy and efficient business ecosystem that benefitted all stakeholders, including the firms, its users, and the environment. With the program still in its early stages, how could BYD and its partners further utilize the green ecosystem’s potential to achieve greater economic and environmental value?

Iloof Technology Co. Ltd. was a Chinese start-up high-technology company at the forefront of the smart water bottle market, one of the newest sectors in the reusable water bottle industry. Smart bottles or cups, also known as interactive water bottles, were technologically advanced devices that had wireless communication capabilities to connect with electronic devices, such as smart phones. They also helped record and optimize the user’s water intake and develop healthy drinking habits. In 2016, after two years of research and development, Iloof Technology Co. Ltd. released its first smart water cup, the HeyDo S1, to great success. However, after three quarters of growth, sales slowed and the company’s founder considered expanding to traditional or offline channels to sustain growth. Could the company operate in both online and offline markets? What potential challenges would the company face in its sales channel expansion?

In February 2020, an entrepreneur and his team in China created a mobile application called Tong Cheng Lian Kang (TCLK), which crowdsourced information on publicly known cases of COVID-19, enabling users to find out if they might have been exposed to an infected individual. The application leveraged blockchain technology to record and validate user submissions of COVID-19 cases to ensure that submission and validation data were immutable, transparent, and decentralized. Users could volunteer to submit publicly recorded cases of COVID-19 or to validate the submissions of others in exchange for digital tokens on the blockchain platform, which they could use to redeem small gifts. As the number of new COVID-19 cases decreased, the entrepreneur wondered how to expand the blockchain concept to build a more sustainable business model. He was considering three options: expanding internationally, which would require building trust with users who lacked familiarity with Chinese applications; diversifying within the healthcare industry by expanding to a business-to-business model, possibly by linking prospective patients to hospitals and health care; and applying the blockchain concept to address issues in industries outside of healthcare. How could he best ensure the sustainability of TCLK?

An estimated 640 million online gamers participated in China’s games industry in 2019. Their pursuit included earning points or tokens that they could redeem for prizes or gifts and in-game assets. A centralized platform allowed game operators to share the administration and management of tokens and rewards, but the system was not as transparent or immutable as stakeholders desired. In January 2019, a new points redemption system was launched based on blockchain technology. The new system, involving game operators, users, custodian banks, suppliers, and tax agents was credible and more transparent, and foreshadowed China’s growing interest in legal digital currency. How policy would shift toward digital currency was unclear; however, the fact that the blockchain race between countries had intensified was clear. The application of blockchain in China’s games industry was just one of the visible examples.
