我国粮食生产力的空间差距分解及影响因素分析 ——基于单要素生产力视角
Analysis on the decomposition of the spatial disparities and the influencing factors of China's grain productivity: From the perspective of single factor productivity
摘要
Abstract
Improving the single factor productivity efficiently is the basis for China's grain security and the improvement of the total factor productivity. Based on the data of 30 provincial areas in China from 2000 to 2015, this paper built an empirical framework, "descriptive statistics- decomposition of Theil Index-spatial regression models", and examined the relationship and differences between the two different indicators, including the grain yield per unit area (yA) and the labor productivity (yL). Results show that: 1) Domestic researchers usually prefer yA, while foreign researchers often select yL, as the measuring indicator of agricultural productivity. The difference in selecting indicators originates from different research paradigms. The indicator selection will affect the general tendency profoundly when making and enforcing grain policies; 2) The spatial distribution of the two indicators displays a gradual declining trend from the northeast to the southwest and there is no obvious linear relationship between them. Opposite trends have been shown obvious difference after decomposing the Theil Index of the two indicators; and 3) Spatial regression analysis shows that farmland transfer and intermediate inputs have consistent influences on these two indicators in terms of the direction, magnitude and significance level of the estimated coefficients. However, the models' goodness of fit performsbetter when yL is treated as the dependent variable than when yA is treated as the dependent variable. Policy implications of this paper include enforcing and optimizing the current polices in a more targeted and heterogeneous way.关键词
