生产性服务、迂回投资与农业化肥减量增效
Productive Services,Circuitous Investment and Agricultural Fertilizer Reduction and Efficiency Improvement
摘要
Abstract
Reducing the amount of agricultural fertilizer and increasing its efficiency are im-portant measures to comprehensively consolidate the foundation of food security and accelerate the construction of ecological civilization.China's agricultural fertilizer reduction and efficiency im-provement has great potential,but the quality of small-scale management organization has many constraints on the application of fertilizer reduction and efficiency improvement technology,resulting in the lack of overall and long-term policy measures.This paper constructs an analytical framework of"productive services-circuitous investment-fertilizer reduction and efficiency im-provemet"to explore the internal mechanism in helping farmers to cross the technology gap through the roundabout investment path of agricultural productive services and finally achieve fer-tilizer reduction and efficiency improvemet.Based on the panel data of Chinese provinces(cities and districts)from 2000 to 2021,the empirical analysis finds that agricultural productive services can significantly reduce the intensity of fertilizer application and improve the efficiency of fertilizer application.Agricultural productive services and other control variables together explained 1.26％and 15.92％ of the changes in the intensity and efficiency of fertilizer application,and the explan-atory power of agricultural productive services reached 2.48％ to 26.28％,and 71％ to 82.13％,respectively.The mechanism analysis shows that roundabout investment effect is a key mechanism of agricultural productive services driving fertilizer reduction and efficiency improvemet.However,due to the inherent characteristics of fertilization link,link service is more dependent on the fast and flexible response of small-range and short-radius collaboration,while the cross-regional serv-ice with large-range and long-radius collaboration has limited fertilizer reduction and efficiency improvement.Nevertheless,the service market pattern that combines large-scale cross-regional services with multi-center and small-range local services is still conducive to promoting fertilizer reduction and efficiency improvement.关键词
