Impact of pesticide use zero-growth policy on the total amount and intensity of pesticide utilization
The pesticide use zero-growth policy was implemented in 2015;however,the quantitative assessment of policy effect,especially the heterogeneity of pesticide reduction effect and moderating effect of price mechanism on pesticide use reduction has not received much attention.To narrow these gaps,this study constructed a panel data comprising the data from 26 provinces in China from 2010 to 2019.Based on the dataset,this study used the static panel,dynamic panel,and moderating effect models to investigate the impact of zero-growth policy on pesticide use and the moderating effect of market price mechanism on the reduction effect of pesticide use zero-growth policy.The models' estimation results revealed that the zero-growth policy significantly reduced the gross amount and intensity of pesticide use,while the reduction effect declined over time.Furthermore,there were regional difference in the pesticide use reduction effect of the zero-growth policy.The zero-growth policy has caused a greater reduction effect on pesticide use in non-major grain producing areas than in major grain producing areas.Besides,the reduction effect on the total amount of pesticide use was slightly higher than the intensity of pesticide use.Finally,the market price mechanism had a significant moderating effect on the reduction effect of the pesticide use zero-growth policy,which is measured as the ratio of the produce price index to pesticide price index.The increase in produce price could encourage the use of pesticide and discourage the reduction effect of pesticide use zero-growth policy.To achieve the optimal control effects,this paper proposes those suggestions such as building a price subsidy mechanism for green control technology according to regional characteristics,strengthening rigid constraints on pesticide utilization intensity,and paying more attention to the linkage between zero-growth policy and agriculture-related market price mechanisms.
