With the emergence of the digital age, smart healthcare services based on the new generation of information technologies play an increasingly important role in improving the quality of resident health. This study empirically examined the impact of regional smart healthcare services on resident health as well as the underlying mechanism by employing a two-way fixed effects model. We constructed a Regional Smart Healthcare Service Development Index and matched it with survey data from the China Health and Retirement Longitudinal Study to validate the model. The results showed that (1) smart healthcare services have a significant positive impact on resident health. (2) The availability of outpatient services and inpatient services plays a mediating role in the relationship between regional smart healthcare services and resident health. (3) The influence of regional smart healthcare services on resident health is heterogeneous among different regions. Specifically, the effect of smart healthcare services on resident health is significant in the eastern regions, while it is not significant in the central, western, and northeastern regions. The effect of smart healthcare services on resident health is significant in rural regions but not in urban regions. This study enriches the nascent research stream of smart healthcare services. This study offers useful insights for practitioners and the government to guide them in formulating smart healthcare strategies.

Received multinational enterprise theories are challenged by the progress of digitization. How do emerging-market multinational enterprises utilize cross-border merger and acquisitions to improve innovation quality in the digital economy era? To shed light on this question, we combined the literature on network balance with a digital gap perspective. We conducted a bootstrap repeated-sampling analysis of a sample of 146 overseas mergers and acquisitions conducted by Chinese-listed manufacturing companies between 2001 and2016. We found that network-embedding balance has a positive impact on the quality of post-M&A domestic and international innovation, and that China's digital development has not promoted a positive correlation between network balance and innovation quality. In the presence of a wide digital gap between a firm's home and host countries, network balance can significantly improve the quality of post-overseas M&A domestic innovation; conversely, when this gap is narrow, a firm can use the interaction between network balance and the host country's digital level to improve the quality of its international innovation. Chinese manufacturing enterprises can enhance their ability to obtain highly complex tacit knowledge by increasing their digital level. In this paper, we explain a new mechanism that digital economy emerging-market multinational enterprises can use to construct a balanced network and thus gain global innovation advantages.
