Research on the impact of informal learning duration on the production efficiency of herdsmen in Inner Mongolia
To analyze the impact of informal learning duration on the production efficiency of herdsmen,this study utilized micro-data from 439 herdsmen households across three leagues and cities in Inner Mongolia.A stochastic frontier production model was employed to estimate production efficiency,and empirical analysis was conducted by using the Ordinary Least Squares(OLS)and Two-Stage Least Squares(2SLS)models.The findings revealed that the effect of informal learning duration on production efficiency exhibited an"inverted U-shaped"relationship,primarily mediated through technology adoption.Furthermore,the study addressed potential endogeneity issues,and the conclusions remained valid after applying instrumental variables.Further robustness checks,including winsorizing and variable substitution,confirmed the stability of the results.Heterogeneity analysis indicated that informal learning served as a necessary complement to formal learning,and improved internet quality could shift the balance point of optimal informal learning duration to the left,thereby enabling herdsmen to maximize production efficiency within a shorter time.Consequently,the government should focus on enhancing internet infrastructure in pastoral areas,assess the herdsmen's skill and management needs,and utilize platforms such as official social media accounts to foster self-learning awareness and stimulate autonomous learning potential among herders.
