耕地地力保护补贴对福建省农业全要素生产率的影响

Effects of the Subsidies for the Protection of Cultivated Land Fertility on Agricultural Total Factor Productivity in Fujian Province

【目的/意义】随着农业三项补贴的改革,财政结构发生转变,探索耕地地力保护补贴是如何影响农业全要素生产率的变化有助于完善补贴政策,为促进福建省农业发展提供参考和启发。【方法/过程】采用DEA-Malmquist模型,对泉州市、宁德市和漳州市的农业全要素生产率进行测算,并通过Tobit模型对农业全要素生产率进行回归分析。【结果/结论】结果表明:技术效率是引起农业全要素生产率增长的主要原因;从农业全要素生产率的影响因素来看,耕地地力保护补贴资金和年日照时数显著正向影响农业全要素生产率,各县市GDP、户均耕地面积和年平均气温显著负向影响农业全要素生产率,而年降雨量与农业全要素生产率呈负相关关系。

【Objective/Meaning】With the reform of three subsidies in agriculture,the financial structure has changed.Exploring how the subsidies of farmland productivity protection affect the changes of total factor productivity in agriculture is helpful to improve the subsidy policies and provide reference and inspiration for promoting the agricultural development in Fujian Province.【Methods/Procedures】By using the DEA-Malmquist model,the total factor productivity of agriculture in Quanzhou City,Ningde City and Zhangzhou City was calculated,and then the Tobit model was used to make regression analysis on the total factor productivity of agriculture.【Results/Conclusions】The results showed that the technical efficiency was the main reason for the increase of agricultural total factor productivity.From the perspective of the influencing factors of agricultural total factor productivity,the subsidies for the fertility protection of cultivated land and the annual sunshine duration had significant positive impact on the total factor productivity of agriculture.The GDP of each county and city,the average cultivated area per household,and the annual average temperature had significant negative impact on the total factor productivity of agriculture,while the annual rainfall was negatively correlated with the agricultural total factor productivity.
