Spatial-temporal Differences of Agricultural Total Factor Productivity:Restudy of Previous Literatures
基于1982至2011年的文献，重新计算中国农业全要素生产率，发现1978至2008年间年均增长3.17%，存在技术进步与技术效率损失并存、东中西区域不平衡的特征。
In order to reveal the accurate agricultural total factor productivity in China,this paper investigate the temporal and spatial nature of agricultural total factor productivity based on previous literatures from 1982 to 2011.The results show that:during 1978 to 2008,agricultural total factor productivity grows at 3.17% annually and presents characteristics of technological progress and technical efficiency loss coexistence.In view of three areas,there exists regional imbalance in China's agricultural total factor productivity and the rank ordering is eastern,middle and western,meanwhile the growth of agricultural total factor productivity is mainly promoted by the technology progress whether in eastern,middle or western.The above conclusions are obtained from agricultural total factor productivity calculating literatures by various authors using different methods and data.Therefore,it can reflect the growth of agricultural total factor productivity more accurate and objective.
