Effects of Black Soil Protection Policy Instruments on Agricultural Green Total Factor Productivity and Its Spatial Differences
This study categorizes black soil protection policy instruments into three types:supply-oriented type,demand-oriented type,and environment-oriented type.Based on the data of 297 new-type agricultural management entities in 5 counties and districts,this study analyzes the effects of black soil protection policy instruments on agricultural green total factor productivity(GTFP),and further examines its mechanism and geospatial heterogeneity.The results indicate that:1)Black soil protection policy instruments and their combinations have achieved the innovation compensation effect,and significantly enhance agricultural GTFP.2)The marginal effect of the demand-oriented policy instruments on promoting agricultural GTFP is the largest,followed by the environment-oriented type,and the supply-oriented type is the least.Currently,the using proportion of policy tools is 18.8%for the demand-oriented type,30.0%for the environment-oriented type,and 51.2%for the supply-oriented type,which indicates that market mechanisms are more efficient than direct government intervention.3)The effect of black soil protection policy instruments on agricultural GTFP is geographically heterogeneous.The marginal effect of the supply-oriented policy instruments from high to low is Keshan,total sample,Longjiang respectively.The marginal effect of the demand-oriented policy instruments from high to low is Beilin,Keshan,Longjiang,total sample,Lanxi,Yi'an respectively.The marginal effect of the environment-oriented policy instruments from high to low is Keshan,Longjiang,Yi'an,total sample,Lanxi,Beilin respectively.4)The supply-oriented policy instruments improve agricultural GTFP by facilitating scale management,the demand-oriented policy instruments improve agricultural GTFP by stimulating market participation,and the environment-oriented by influencing risk perception.
