Technical Efficiency of Chemical Fertilizer Use and Its Influencing Factors in China’s Rice Production

Low technical efficiency and excessive usage of chemical fertilizer in grain production is a problem commonly faced by China many other developing countries, which leads to serious environment pollution high environmental governance cost. the largest rice producing consuming country, several kinds are grown all important edible grain. However, there has been no systematic research on kind difference provincial use (TEFU) for production. Using data China’s 22 provinces from Agricultural Product Cost-Benefit Compilation Statistical Yearbook, this study measures TEFU early indica rice, intermediary late japonica using stochastic frontier function (SFPF) model, then analyzes TEFU’s influencing factors Tobit model conducts robustness check panel fixed effect model. We found that, average, four were improved significantly during 1997–2018, increasing 67.70%, 39.93%, 14.76%, 21.88%, respectively. have significant differences among different provinces, still large improvement potential. Government’s fiscal support agriculture, agricultural labor productivity, mechanization, effective irrigation, implementation “Soil Testing Formulated Fertilization Program” (STFFP) positive impact TEFU; natural disaster price negative TEFU.
