数字素养对牧户超载过牧行为的影响及作用机制研究OACHSSCD

Overgrazing remains a prominent challenge to grassland ecological conservation,and information asymmetry in herders' access to key production resources is one of its major contributing factors.Enhancing digital literacy can improve herders' ability to obtain relevant information,reduce their dependence on natural grasslands,and thereby facilitate a transition toward more ecologically friendly livestock management practices.Based on micro-level survey data from herdsmen,this study constructs a multidimensional measure of digital literacy-encompassing digital information literacy,digital social literacy,digital financial literacy,and digital security literacy-and empirically examines the impact and mechanisms of digital literacy on overgrazing behavior.The results indicate that an improvement in digital literacy significantly suppresses overgrazing behavior among herdsmen.This conclusion remains robust after controlling for potential endogeneity and conducting multiple robustness checks.Further mechanism analysis indicates that digital literacy reduces herders' overgrazing behavior by improving the reliability of information search.Among the dimensions of information search reliability,the mediating effects of grassland leasing information reliability and forage price information reliability are the most prominent,whereas the mediating effect of livestock breeding technology information reliability is not significant.In addition,the effects of different dimensions of digital literacy on overgrazing vary markedly,with digital social literacy and digital financial literacy demonstrating stronger inhibitory effects.Based on these findings,this study recommends accelerating digital literacy initiatives in pastoral areas,with a particular focus on strengthening digital social and financial literacy,implementing differentiated intervention strategies based on the degree of overgrazing,and improving the rural information service system to reduce information search reliability.
