环境规制视角下奶牛场粪污资源化利用技术采纳强度影响因素分析OA

This study aims to explore the intrinsic connections and driving factors behind the adoption intensity of source reduction technologies,process control technologies,and end-of-pipe treatment technologies in dairy farms.Based on survey data from 412 large-scale farms nationwide in 2023,the study used the Multivariate Probit model and Covariance Analytic Hierarchy Process(Cov-AHP)to analyze the correlation effects between the adoption behaviors of the three types of technologies and the influencing factors of adoption intensity.The results indicated a significant complementary relationship between the three types of technologies,with positive correlations observed between technologies such as dry manure cleaning and composting agents,as well as biogas production and fertilization.The national average adoption intensity of technologies was 2.215,with the highest in North China and the lowest in Northeast Inner Mongolia.Medium-sized farms showed significantly higher adoption intensity than small-sized ones.Incentive-based and guidance-based environmental regulations significantly enhanced adoption intensity,while constraint-based regulations suppressed it.Technological awareness played a mediating role between environmental regulation and technology adoption,with the mediation effect accounting for 4.4％-18.1％of the total effect.In particular,under constraint-based regulations,enhancing awareness could mitigate its negative impact.In conclusion,the technology adoption behavior of farms is synergistic,and its intensity is driven by the interaction between the type of environmental regulation and technological awareness.Regional differences and scale heterogeneity indicate that policy design needs to consider both technological interrelationships and the enhancement of awareness.
