The association between religion and health is well debated and receives continuous attention in research. Selection bias is often a major concern among the observatory data routinely used worldwide to examine this topic. Adopting the propensity score matching (PSM) method, the present study tries to assess the treatment effects of religion on self-reported health status. The final sample from the 2007 Spiritual Life Study of Chinese Residents (SLSC) contains 6194 valid responses. The average treatment effects (ATEs) estimated by the PSM method show that respondents with religious affiliations are on average significantly more likely to report being very healthy by 5.2 percentage points (by 3.6 and 9.6 percentage points among Buddhists and Protestants), especially, by 16.2 percentage points among those regarding religion as being very important in their lives. Meanwhile, ATEs of religion on reporting being very happy is 17.0 among Protestants and 13.4 among those regarding religion with high importance and 11.3 among those with “regular religious attendance”.

In recent years, the Sustainable Development Goals have introduced a “race to the top” mechanism to complement the “race to the bottom” in local governance and have an impact on pollution. This study utilizes the environmentally oriented accreditation of National Civilized Cities as a policy shock and applies the PSM-DID method to identify the pollution-relocation effects among cities triggered by the competition in local governance. The results indicate that environmentally oriented intergovernmental competition leads to the transfer of industrial enterprises to non-accredited cities, resulting in a significant increase in their pollution emissions and industrial pollution intensity. This indicates that the competition in asymmetric local governance will lead to the transfer of pollution to backward regions, which hampers the overall implementation efficiency of national environmental policies. Furthermore, heterogeneity analysis reveals that the impact is more significant for cities in the central and western regions. Being nominated for the National Civilized City accreditation helps to inhibit the influx of polluting enterprises. Cities that are not part of integrated environmental regulatory regions show a more pronounced increase in pollution emissions compared to other cities, indicating that symmetric local government environmental regulations and environmental collaborative governance contribute to restraining pollution transfer.
