The application of mobile health holds promises of achieving greater accessibility in the evolving health care sector. The active engagement of private actors drives its growth, while the challenges that exist between health care privatization and equitable access are a concern. This article selects the private internet hospital in China as a case study. It indicates that a market-oriented regulatory mechanism of private mobile health will contribute little to improving health equity from the perspectives of egalitarians and libertarians. By integrating the capability approach and the right to health, it is claimed that mobile health is a means of accessing health care for everyone, where substantive accessibility should be emphasized. With this view, this article provides policy recommendations that reinforce private sector engagement for mobile health, recognizing liberty, equity, and collective responsibility in the Chinese context.
