THE STABILITY OF MANAGEMENT RIGHT,SCALE OF LAND TRANSFER,AND FARMERS'USE OF CHEMICAL FERTILIZERS——AN EMPIRICAL STUDY BASED ON MICRO DATA AT THE TRANSFERRED LAND
Demonstrating the impact of the stability of farmland management rights on farmers' use of chemical fertilizers,and based on the perspective of property rights theory,we construct a theoretical analysis framework of"farmland management rights stability-scale of land transfer-amount of fertilizer application."This framework provides decision-making references for government departments to formulate policies for reducing fertilizer use,aiming to promote green and efficient agricultural production.Utilizing survey data from 1 040 households in four provinces(Heilongjiang,Henan,Sichuan,and Zhejiang)in 2015,we employed the mediation effect model to reveal the relationship and pathway through which the stability of farmland management rights affected farmers' use of chemical fertilizers.We also attempted to introduce instrumental variables to alleviate endogeneity issues in the model.Overall,the stability of farmland management rights significantly reduced farmers' use of chemical fertilizers.From different dimensions of the stability of farmland management rights,it was observed that longer land transfer periods and signing contracts during the transfer process helped reduce the amount of chemical fertilizer used by farmers.The stability of farmland management rights had both direct and indirect effects on farmers' use of chemical fertilizers.Stable farmland management rights in terms of duration and power protection would significantly reduce farmers' use of chemical fertilizers by expanding the scale of land transfer.Therefore,long-term stable farmland management rights and clear contractual responsibilities in land transfer are important factors in reducing farmers' use of chemical fertilizers.The government should actively guide the longer-term transfer of land to ensure sustainability in the temporal dimension.Moreover,the government should strengthen the standardized management of land transfer and cultivate farmers' awareness of contracts.Additionally,the government should actively promote the transfer of idle farmland and provide policy incentives tailored to local conditions.
