MECHANISM AND EMPIRICAL ANALYSIS OF THE INFLUENCE OF LAND ENDOWMENT ON REDUCTION IN CHEMICAL FERTILIZER USE
Studying the relationship of land endowment and reduction in chemical fertilizer use is important for improving the agricultural ecological environment and promoting the green development of agriculture.Based on the survey data of 882 farmers in five provinces around the Bohai Sea,the Probit model was used to study the relationship between the chemical fertilizer use and four aspects of land endowment:scale,fragmentation,natural attributes,and property rights.The results were showed as follow.(1)81.18%of farmers experienced excessive fertilization,resulting in huge potential for fertilizer reduction;(2)The land scale and the reduction in chemical fertilizer use had an"inverted U-shaped"relationship,and it was necessary to maintain a certain scale;(3)For small farms,land fragmentation increased the probability to reduce chemical fertilizer use;(4)Compared to rented land,farmers had higher probability to reduce chemical fertilizer use in their own land;(5)Educated farmers and farmers without non-agricultural income were more"rational"and good at"adapting the chemical fertilizer use based on different land endowments",while uneducated farmers and part-time farmers were more likely to be"path dependent",and their fertilizer use was not sensitive to the heterogeneity of land endowments.Therefore,in order to further reduce chemical fertilizer use,it is necessary to improve the land market conditions,encourage the moderate-scale operation,increase agricultural production subsidies,give subsidies based on farmers'characteristics,provide the agricultural production service to support the reduction in chemical fertilizer use.
