High-standard farmland construction (HSFC) is a key measure to ensure national food security. The development of digital technology has brought new opportunities for HSFC. Based on panel data from 30 provinces (municipalities and autonomous regions), this paper employs a two-way fixed effects model, a panel threshold model, and a spatial Durbin model (SDM) to empirically examine the impact of digital technology on HSFC efficiency, as well as its threshold and spatial spillover effects. The study yielded the following key findings: First, digital technology has significantly improved the effici...
