环境规制与畜牧业经济绿色转型OACHSSCD

Under the increasingly severe ecological and environmental constraints,the construction of a multi-level and comprehensive environmental regulation system is driving the restructuring of the livestock production model.This study aims to empirically examine the nonlinear relationship between environmental regulation and the green transformation of China's livestock industry,so as to provide scientific evidence for the rational formulation of environmental policies.Using the panel data from livestock industry between 2007 and 2022,the SBM model and panel threshold model were applied to analyze the relationship between environmental regulation intensity and green total factor productivity.The results were showed as follows.(1)Over the 16 years,China's livestock green total factor productivity generally showed an upward trend,but there were significant regional differences.The green total factor productivity in the centralsouthern,southwestern,and northwestern regions of China was lower than the national average.(2)The main reason for the lagging efficiency in some regions was the significant waste of capital and human resources.(3)Further analysis revealed that environmental regulation intensity had a single-threshold effect on green total factor productivity,with a threshold value of 0.359 2(95%Confidence Interval:0.330 8-0.379 6),and the impact of environmental regulation intensity on green total factor productivity followed an inverted U-shape,which first promoted and then inhibited productivity.(4)Additionally,regional economic levels,industrial structure,scale of production,and labor quality significantly contributed to the improvement of green total factor productivity.Overall,there are significant regional disparities in the green transformation of China's livestock industry,and there is still considerable room for improvement in the transformation level in various regions.Therefore,each region should select environmental regulation tools flexibly according to its own economic and social development realities,and maintain regulation intensity within a reasonable range to stimulate the endogenous drive for regional livestock green transformation.
