摘要:
为探究实施农机购置补贴与农地流转以来中国农业TFP的发展规律及增长源,运用Hicks-Moorsteen指数法测算并分析了中国农业TFP的时空差异,并通过Dagum基尼系数及其分解方法探究空间差异存在的内源构成。结果表明:中国农业TFP呈持续增长态势,驱动要素主要是技术进步而非技术效率;中国7个区域农业TFP增长态势表现不一,各区域的增长来源也不尽相同;不同区域间农业发展潜力存在显著差异;7个区域农业TFP的总体差异存在逐步扩大的趋势,而区域间差异是总体差异的主要诱因。

Abstract:
In order to explore the development rules and growth sources of Chinese agricultural TFP since the implementation of agricultural machinery purchase subsidy and farmland transfer, this research calculates and analyzes the spatial-temporal differences of Chinese agriculture TFP by the Hicks-Moorsteen index, and further uses the Dagum Gini coefficient and its decomposition method to explore the endogenous composition of spatial differences. The results show that: Chinese agricultural TFP is in a sustained growth trend, and the driving factor is technological progress rather than technological efficiency. The growth trend of agricultural TFP in China's seven regions is different, and the growth sources in each region are also different. There are significant differences in agricultural development potential among different regions. The overall differences of agricultural TFP in the seven regions have a gradually expanding evolution trend, and the interregional differences are the main triggers for overall differences.
Key words:  Chinese agriculture  total factor productivity  spatio-temporal evolution  Hicks-Moorsteen index  sources of differences
