This study analyzed Chinese labor-force survey data to determine the relationship between cropland abandonment and high-speed rail (HSR) infrastructure. A PSM-DID approach was employed to examine 2014 and 2016 data from the China Labor-force Dynamics Survey and estimate the impact of HSR, from which it was found that HSR accessibility promoted cropland abandonment in local farm households with a coefficient of 0.206, that is, HSR projects led to a 20.6% increase in area of cropland abandonment and these impacts were found to be greater in hilly areas and lower in plain areas. The results also suggested that HSR accessibility could have a “pull” effect, which resulted in rural labor force shifts to non-agricultural sectors in the local region. Countermeasures and policy suggestions are given to reduce cropland abandonment.

This paper examined the effects of household technology on child health using evidence from the Chinese government’s “Home Appliances Going to the Countryside” policy. A difference-in-differences approach was employed to examine 2000 to 2015 data from the China Health and Nutrition Survey data from before the policy in 2007 to after the policy was implemented. It was found that the policy-induced household technology adoption significantly increased child health, especially girls’ health. Various sensitivity tests proved this finding to be robust. The potential paths through which household technology improved child health were also examined from which it was found that parental care for children and increased nutrition were effective paths between household technology and health status. These results could guide policymakers when constructing and developing a supportive child health system in China.
